We have a SBS 2008 server that has 2 removable USB hard drives which are rotated on a daily basis, everything has been working fine for the last 2-3 years on this basis however recently the SBS server has stopped detecting one of the removable USB hard drives when its rotated and plugged in.

When I run the Western Digital utils the hard drive is connected and can be scanned but USBTools reports Access denied and the volume could not be mounted as shown below, I have no idea whats going on and nothing has recently changed to my knowledge.

Greetings.  We have a nice HP SAN that is currently backed up using Symantec Backup Exec 2014 to a Western Digital NAS box.  Good redundancy, but not offsite.

I'm curious what other small businesses are using for offsite backup these days ?  One of our IT consultants mentioned a Barracuda solution with an onsite appliance.

We have a 40Mb/s pipe (up and down) and about 1TB of user data.  I have no problem with an archive type of storage (i.e. once a week or every two weeks, an upload of incremental changes).  The data would not need to be accessed unless a total disaster struck our organization.  We're a non-profit, so I know some discounts are available out there.

Ideas ? Suggestions ?

I just installed an Inateck 2-port USB 3.0 PCIe card (model KT4006) in my Dell T110 II server.  I would like to know if it is configured properly to run at maximum speeds.  Inateck sent me an email when I ordered saying I should install the latest driver from the Fresco Logic Website.  I installed the Fresco Logic xHCI USB 3.0 controller driver dated 1/15/2015.

I then ran LANspeed tests from my server to several attached storage devices with file sizes ranging from 20MB to 1.5GB.  Here is a summary of the results, expressed in Mbps (megabits per second)

A. RDX 3.0 drive connected with MOBO USB 2.0 (this is a baseline before installing card)
 - Write: 149 - 211 Mbps
 - Read: 253 - 264 Mbps

B. Quantum external RDX 3.0 drive connected with USB 3.0 before installing Fresco drivers**
 - Write: 254 - 290 Mbps
 - Read: 480 - 521 Mbps

C. Quantum RDX 3.0 drive connected with USB 3.0 after installing Fresco drivers
 - Write: 342 - 447 Mbps
 - Read: 516 - 522 Mbps

D. Western Digital Passport Essentials USB 3.0 drive
 - Write: 466 - 494 Mbps for files 150 MB+ (50MB file was 683 Mbps)
 - Read: 522 - 606 Mbps

** Note the RDX was configured to NOT use it's internal buffer.  This means I do not need to do a safely remove.  When I set the drive to use the buffer, write speeds jumped to some huge number (5,000 or 10,000 - cannot recall).

I did a lot of research looking for a USB 3.0 card that would work in 2012 R2.  It came down to this Inateck and a card …
My office server is running Server 2012  Datacenter R2, fully patched. I setup a Storage Pool using 2 Western Digital Red 3 TB drives. Configuration is Mirrored, Thin Provisioned with a 5 TB capacity. Everything is working fine, but recently, when I look at the Storage Pool, it says that it is 99.6% used and only has 25 GB of free space!? Have not changed anything that I can think of.

However, the 2 Volumes in the pool show that they have the following:
Volume D: 1.25 TB Capacity and 816 GB Free
Volume E: 3.75 TB capacity and 2.82 TB Free

I've tried various powershell commands to trim, defrag, slabconsolidate.
I also moved  142 GB of files off the Storage Pool - and the free space remained at 25 GB?!

Nothing helps - and I am not by any means a storage spaces or powershell expert - just trying things that I've discovered in my research.

This screenshot shows what, to  me, doesn't make sense. Disks with lots of free space and a storage pool that is almost full!:
Am I missing some important concept or is my Storage Pool somehow corrupt, etc.? Any ideas on how to repair or make sense of what I'm seeing?
I have a Western Digital external hard drive. I don't know the model. It doesn't say anywhere. I access the ext hd using a Cat6 cable. We had an issue with our server and network going down. I am attempting to recover the data off the ext hd. I have the hd at a different location. When i plug a cat6 cable into the hd, i can tell it has an IP. I can ping it too. How do I access the files? When i go to network and look for it, i don't see it. When i type \\192.168.xxx.xxx in explorer, nothing comes up. What do i need to do to access the files? Thanks!!!
I have a 3TB Western Digital hard drive which I can view all the file/folders on yet when i open any of the files regardless of file type it states the file maybe corrupt.

In Windows 7 I ran a chkdks from the command-line which did repair some index yet it error out stating it was not able to recover the MBR table due to lack of space. Yet 1.5GB of free space is on the drive.

1) Does an external drive have an MBR?
2) Are they an GPT tools in windows which I should use?
3)  I was able to open some files after the chkdks but not all of them
4) It sounds like the partition table is messed up is my only option to use a recovery software..


I have a NAS that I want to backup to external HDDs using Robocopy.  I am looking for advice on some specific questions how to do this.  Here is some background info and then I will ask my questions.  

Synology DS412+ with four Western Digital 2TB Red drives.  The drives are configured in RAID 6 so I effectively have a single 4TB volume.  This Volume has four shared folders, the largest having 16,000 video files totaling 1.4 TB.  (Note: One of these drives recently failed and I needed to rebuild the RAID array.  For this reason I really want to have the files backed up the way described below).

This Synology is currently backed up to a 4TB Western Digital green drive that is connected to the NAS via eSATA.  I am using Synology's backup software.  I do not like this solution very much because the files are backed up in a way that I cannot see them from my Windows PC.  Also, if the NAS were to completely fail I want to be able to attach the HDD to my Windows 7 PC and read the files.  This is not possible now because the NAS backs up the file in some form of Linux format/OS.  

Backup Plan
I purchased two WD 4TB green drives for my backup.  My plan is to first backup all the NAS files to one drive using Robocopy.  This will take many, many hours over the network since I am talking about a total of 2.5TB of data.  

Once the NAS is all backed up to Disk #1, I will use a Sabrent Dual Bay HD Docking Station to clone Disk #1 onto Disk #2.

I will then …

Up to today I've made a backup of my 'iTunes' folder about once a year. Each time I've simply copied the 'iTunes' folder to an external hard drive, ... which means that most songs/albums are stored multiple times on my backup hard drive (I have one hard drive dedicated only to backup my music). I always assumed that there must be a better way to backup my music files, but I just never got around to doing it.

I'm using a 2TB Western Digital portable hard drive with 'SmartWare' pre-installed, ... but I think WD charges £19.99 per year if I want to use it.

Isn't there an easier and less expensive option to do this?

Many thanks in advance,

Just got a USB casing & an (think it's mSATA) HDD : after assembling & insert into a few
PCs/laptops, though I can heard the disk spinning & the casing's LED lighted up, all the
laptops Win 7 could not detect it.

For the common brands like Western Digital, Toshiba, usually Windows will auto-
install some sort of driver.  Is there a way to activate a generic USB driver for this
setup in a manual way to be able to use this USB casing with HDD?

What are the common USB casings for HDD that are known to be detectable by
Win XP & Win 7 with drivers auto-install?

Can always get another casing that will auto-install driver as this one is really cheap at US$11

I have a roughly one year old Synology DS412+ NAS that started sounding an alarm.  The NAS is configured with 4 hard drives, all 2TB Western Digital Red NAS drives.  The drives are configured in RAID 6 with data protection.

I store music on one of the volumes and noticed that when I went to play song lists starting a couple of days ago Windows Media Player would sometimes crash.  A few minutes ago the NAS started sounding an alarm.  Apparently Disk #4 has failed.  When I log in I see the message in my first image attached.  DS412-Error.png
I also saw that my notifications log exploded in size with many I/O error messages.  See this screenshot: NAS-notifications.png
Here are my questions.

1. What should I do now?  I need to see if I have a spare drive.  I kind of remember buying an extra - but need to check.

Assume I do not have one on hand.  Should I shut the NAS down?  If so, what is the best way to shut it down?

Assume I do have a spare drive, how do I replace / rebuild disk 4?

Hearing this constant alarm is a bit unnerving.  I also have all my home videos and photos on the NAS and pray I will not lose them!  Thanks!

Update:  As far as I can tell, I do NOT have a spare drive.  My bad.  So I think I need to shut the unit down, but will wait to hear advice.
I'm helping my neighbor with his laptop. It won't start into windows. so I took his hard drive out of the laptop and put it in my computer and ran check disk on it. It repaired a number of things, and I put it back in his laptop. This time when it booted it ran check disk again, and again repaired a number of things, but still wouldn't boot into windows. So I booted to the windows 7 dvd and ran the repair windows routine, and got to this window.

It found the instance of windows 7 and attempted repairs, and even said that the repairs were successful, but after restarting, it still didn't boot into windows. It shows that windows symbol for awhile, then just a cursor, and it just sits there. I tried the win7 dvd again, and this time chose system restore, but it couldn't find a restore point.  So my question is. Is there some other windows 7 repair to try? Or does it look like I should just back up his files and reinstall win7? If I do reinstall windows, before I do, I want to run a disk diagnostics on the drive. The thing is, for a western digital drive for example, I usually go to their website and get their disk diags. However, this is a Hitachi and I can't find a diagnostic for this type of drive. Any ideas?
I have a hard drive that I scrubbed with some software but I guess it did too good of a job. I pulled it from the computer and have it hooked to another via usb. When I try to do a chkdsk I am getting a message:

'The disk check could not be performed because Windows can't access the disk.'

So how do I fix this thing so I can install Win 7 back on it in my other computer?

It is hooked to a computer right now that is running Win 7 SP1 and the drive is  Western Digital 1-TB
What hard drive recovery service
or tools do you recommendations
in the USA (Chicago if possible) ?

•      Employee stored data on local C drive instead of network folder
•      western digital
•      SATA
•      250GB
•      Plugged hard drive into my laptop, checking “show hidden files”, nothing displayed
•      Plugged hard drive back into original desktop, inserted Windows 7 disk, Windows found Recovery, tried to do recovery, failed

Maybe one of the below or some TOOLS so I can do on my own ?

I am trying to connect a 2TB Western Digital USB drive to a Ubuntu server.  When I do, I get the following errors (some occur multiple times)

usb 1-6: device descriptor read/64, error -71
hub 1-0:1.0: unable to enumerate USB device on port 6
SD 5:0:0:0: rejecting I/O to offline device

Another USB drive will mount without to the Ubuntu server on the same USB port without errors
The WD drive will mount to a windows machine, also without any problems.
Western Digital support says "we don't support Linux"

Any help will be most appreciated.
Hello experts,

Based on your vast experience, could you guys suggest a reliable HDD for Dell XPS 8700 desktop?

I understand that HDDs are never reliable and frequent backups are to be made for important data.

I really like Western Digital Red drives and was wondering what other drives are comparatively better..

Thanks for your time and insights.
Currently going through hell trying to find a 4TB External USB HDD capable of backing up all of our data (This is SOLELY for off-site backup/ISO compliance. On-site backups are handled with a separate NAS).

I've just purchased 2x 4TB Seagate GoFlex drives hoping to use them alongside Window Server Backup.


Turns out the drives I purchased are reporting themselves as 'natively' having physical 4K sectors.

I have been hunting high and low for a 4TB drive that supports 512 byte emulation; I'm getting mixed reports about Western Digital drives (Will their WD Black 4TB drive in a USB3.0 Caddy allow me to format the drive as 512b sectors?)

Thanks in advance. This is REALLY causing me a nuisance! My next final step is to crack these two external drives out of their enclosures and put them both into a Netgear ReadyNAS or something to cover off-site backups. (Will this even work!?)
I need to thoroughly test multiple hard drives by various manufacturers (mainly Seagate and Western Digital) to see if they are still good, and if they are, see what is on them, wipe them, and prepare them for reuse. Does anyone know of any free tool that will accomplish this? I would prefer a bootable USB Linux tool or a tool that works outside of Windows OS as some of these hard drives may contain a virus. Thanks for reading my post and I look forward to any and all responses.
What is the best IDE to USB hard drive enclosure?

Hard Drives are Western Digital IDE ,
Hello experts,

I'm trying to install 2 Western Digital Red HDDs to my desktop (Dell XPS 8700, that already came with an internal drive)

I'm not sure if I need 18, 24 or 36 inches and straight or angled connections. :(

Could you please recommend something from monoprice?

How about these:



And I guess, I need something like this as well?:


Thanks so very much for your time.
I am trying to get the HARDWARE Serial Numbers of hard-disk drives (which includes SSDs) with WMI (Windows Management Instrumentation):

Class: Win32_DiskDrive
Namespace: root\CIMV2

Now, a customer's computer contains 4 Western Digital hard-disk drives:

WDC WD2002FYPS-02W3B0 ATA Device
WDC WD2003FYYS-02W0B0 ATA Device
WDC WD3000GLFS-01F8U0 ATA Device

And these are the serial numbers of these 4 hard-disk drives I got with the above WMI query:


Please note that these serial-numbers are very similar, so I cannot believe these are the real serial-numbers of these hard-disk drives.
So I used a professional hardware information program (HWiNFO) to compare these serial-numbers with those detected from HWiNFO, and they were totally different.

So I wonder whether it is possible to query the REAL hardware serial-numbers of hard-disk drives by using WMI?

I have a 1.5 TB Western Digital Caviar black drive that I need completely wiped.  This drive is going to be returned to the manufacturer.  I tried running WD's diagnostics tools on it, but the drive failed.  In another question I was told to use Dark's Boot and Nuke (DBAN) to wipe the drive.  I created a DBAN boot disk, unplugged the other HD in my PC, booted into DBAN and started a single pass wipe.  Before starting DBAN showed maybe 5 drives with ????? before it and the HDD I wanted to erase.  I started the simple erase and for the first hour + the system showed steady progress and had an ETA of 4 total hours.  I left the house when it was at 25% complete.  I came back 4.5 hours later thinking it would be done.  Wrong!  Instead it is at 60% with 32 verifying errors.  It is estimating it will need another 23 hours to finish the drive!

I am guessing it ran into the bad sectors that are the reason for my returning the drive in the first place.  I also read online that DBAN works best if I unplug all other drives (except the DVD boot drive) including flash drives, USB ports.

I would hate to have this run for 28+ hours only to learn it did not complete the job.  Should I leave the system alone or should I kill the power and restart the simple wipe after unplugging all other devices?

Is it possible that once the scan gets past the bad drive sectors it will speed up again?

Dear experts,

For some reason, the available free space on one of my external HDDs (Western Digital 2 TB) keeps decreasing. This started just today.

No matter how much free space I create by deleting some of the files, the space keeps going down..! I also noticed a couple of folders missing. There are no downloads currently.

I'm using a Dell XPS 8770 desktop that's running Windows 7 x64.. The system is currently running MalwareBytes Anti-Malware's "Full System Scan" for possible viruses.

Would appreciate any help. Thanks for your time.

I think I just experienced the proverbial "shooting oneself in the foot" syndrome.  I have a custom built PC that uses a CoolerMaster HAF-XM case.  This case has room for 6 internal hard drives and two X-Dock slots for hot swappable removable HDDs. My configuration this morning was as follows:

B: Blue Ray drive
C: Windows 7 boot drive - internal Crucial 128 GB SSD
D: internal Western Digital (WD) Black 1.5TB HDD (that failed and needs to be returned to WD)
E: another internal WD Black 1.5 TB drive
F: second internal 128GB Crucial SSD identical to C
J: new internal WD Black 1.5 TB that will replace failed D drive
H: internal 2TB Seagate HDD
Z drive: 1 TB WD Black drive in X-dock #1

I have an ASUS P8Z77-V LK motherboard running their UEFI Bios utility Bios version 0210.

Earlier today I opened the case to remove the failed D drive.  At that time I got it in my head to move around some of the other drives.  I wanted to move my two working 1.5 TB WD Black drives into my X-docks.  These drives are being used to backup photos and videos from a NAS device and I liked the idea of being able to easily pull them out and swap them.  

I did NOT move or touch either of the two SSD drives (including the C boot drive).  I did move all of the HDD drives into their desired place.  Just when I put the case back together I had a bad premonition - I was wondering if changing the drives would effect booting. In theory, I did not change the boot drive so I thought I was OK. Wrong!


I have a 1.5TB Western Digital Black drive that developed some bad sectors after 18 months.  After using WD's diagnostic tools and chatting with their support, it was determined the best bet was to get a new drive under their warranty program.  WD shipped me a "re-certified" drive that arrived in just two days even though I was quoted 5-7 days (give them an A+ for service), and I have since copied all my files from the bad drive to this new drive.

Now I need to return the bad drive to avoid being charged for the replacement.  The drive was mostly used to store family photos and videos.  There is a slight chance that some sensitive info may also have been stored on it. For peace of mind, I want to wipe the drive before mailing it in.

After deleting all the files and emptying the bad HD's recycle bin (yes I know this does virtually nothing), I started using CCLeaner's Wipe Free space using the 3-pass option.  It appeared this was going to take 12+ hours, so I stopped that process and instead selected three large photos (mix of jpeg and TIFF files) that totaled 100 MB in size.  I started copying and pasting them on this drive.  So far, I have filled 282 GB out of 1,360 GB on this drive with these three photos.  My thinking is that this is a quicker way to at least start the wiping process.  I was going to fill the drive up completely with these three files.  

Is this sufficient?  I could ship the drive back to WD with it full of thousands of copies of these …
I am working on a project that uses VB.Net and GDI+ to generate "lots" of fairly small bitmapped images. Since I am only generating 10's or 100's at a time, performance is not a real issue. However, I am looking at a job where I may have to generate up to a million at a time.

I am not too worried about the performance of generating the actual bitmaps in GDI+, however when I need to start writing so many files to the hard disk I am a bit concerned about that. Right now, I just do a "bitmap.save" -> <hard disk path> after I generate each one.

I am wondering if there are some strategies to optimize the writing out of "many" such small image files. For instance, letting them build up in RAM and writing out a bunch in a burst instead of "generate one, save, generate another, save, and so on..."

I realize the question is kind of vague, so possibly what I really need to know is the right question. Does anyone have some general advice, experience, resources, or comments that might address this issue?

Here are the specs of what I'm running now:
------- Hardware ---------
HP quad core, AMD A8-5500, 3.2GHz
8 Gb RAM
Western Digital WD Blue WD10EZEX 1TB drive
Windows 8 64 bit

------- Software ---------
VB.Net 2010, dot.net Framework 4
resulting bitmap file size ~100k
