Storage Hardware





Storage devices include any device used for storing and retrieving digital information. Hard disk drives (HDDs) use one or more rigid ("hard") rapidly rotating disks (platters) coated with magnetic material. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially. The primary competing technology for secondary storage is flash memory in the form of solid-state drives (SSDs), but HDDs remain the dominant medium for secondary storage due to advantages in price per bit and per-device recording capacity. CD-RW (Compact Disc-ReWritable) is a digital optical disc storage format that allows information to be stored outside the mechanical HDD.

I am running a Dell PowerEdge T310.  I have 2(qty) RAID 1 setups.  The Hard Drives are Hot Swap.  The first RAID runs the O/S and the second my data.  One of the drives in the first RAID has a blinking amber light and states there is a predictive failure.  I can see this through the Dell Server Admin login on the Server O/S.  I am purchasing a new drive that is the same model, size and speed. My question is do I simply just pull the Hard Drive with the Predictive Failure out and insert the new one or should I run the Dell Server Admin and set the Predictive Failure drive to offline and then replace?  What would be the safest/proper way to replace this drive?

I have need to read and write to a solid state 1 tb memory module. One is Samsung and one is Toshiba. I know that there are manufacturers that make external pockets that will accommodate one hard drive or two hard drives. Does anyone know of any manufacturer that sells an external device that I can insert these ssd modules into and read/write  to them? There are 34 pins on each memory module. Enclosed are photos of the two memory modules inserted into the daughter card.
Hardware: Dell Poweredge R630 - running latest BIOS and firmware.  SD card boot;   Accessories: CD drive;  USB port;  [NO Hard Drive]

Operating System: VMWare 6.5.0    5310538

Problem with sticky boot up when restarting a Dell Poweredge R630 VMWare ESXi host which has no hard drive. [i.e. boots up from onboard SD card] It can take 3 attempts to restart the server which appears to successfully boot through all the hardware configurations but stalls when loading the VMWare environment.  I have spoken with Dell who say that this is a VMWare problem. I am not an expert on this but since the server is running at the moment I was hoping that I might be able to copy the current configuration onto another medium and boot up from it in order to eliminate the SD cards.   Does anybody know how to do this?

If the problem is with VMWare how do I diagnose the likely cause? Does anybody know the best course of action?

Thanks to anybody for taking the time to look at this.

I am trying to diagnose an occasional paging file error I am receiving on an HP Proliant ML150 Gen 9 server running Windows 2012 Server R2 Standard.  The warning message is:

warning:  eventid 51
An error was detected on device \Device\Harddisk3\DR291 during a paging operation.

I am trying to figure out which physical or logical device this is pointing to on the server.   Note that the number following DR changes every time there is an entry for this paging error in the system logs.

 I took over administering this server earlier this year.  The server uses an embedded B140i RAID controller for the physical drive connections. The physical disks are set up as follows:

4 X 1 TB SATA drives in RAID-5 array, total available storage c. 2.7 TB
array is split into 2 logical drives:  

  drive C: at c. 400 GB
  remainder is drive N: at c. 2.3 TB

There is also an external Seagate USB 5 TB drive, total available storage c. 4. 7 TB, split into 2 logical drives:

  drive X: at 2.3 TB
  remainder is drive Y: at c. 2.4 TB

I'm attaching a PDF with screen shots of the DISKPART  screen showing disks and volumes as the server sees them, Computer Management / Disk Management screen, My Computer / Drives screen, a Device Manager disk drives summary, and also a tech doc at the beginning of the PDF that provides some decent info on this message but doesn't quite solve it for me.  As per the recommendation of the tech doc I also ran a WMOBJ listing of the …
I have 5 Kingston KC300 240 GB SSDs.  I have a LSI Megaraid 9285CV-8e RAID card version 5.5.  My motherboard is ASRock E3C204-4L with latest available BIOS.  

The SSDs are not detected by the RAID card.  I also tried a Seagate 1 TB HDD and also did not detect it.   I loaded the UEFI defaults in the BIOS but they are still not detected.  On bootup the POST screen says 0 logical drives detected and after logging into the server and launching ServerView RAID Manager, it sees the card but no drives.  All 5 drives are connected to the ports using SFF8087 cables.

Any suggestions?
i have been facing issue with HP ProLiant DL380 G7 Server. Hard Drive bay 1 and 2  steadily have blue light (actually it looks like multi color) and display is not coming on monitor, when i unplug the power jack connected with pcb of hard-drive bay, and turn on the server then display appears on monitor (but no disk drives detected on server because i removed the power jack), again when i plug same power jack ; and turn on the server then again display not coming on monitor.

this server has only 2 drives, 1 in bay 1 and other in bay 2.

I have tried to replace the new hard drive, but still same issue
i have tried to remove the hard drives and turn on the server, but still same issue,
i have also tried to replace the array battery, but still same issue,

would you please advice me for this.
Hi I have some servers that are using software raid on Server 2012 R2.  I was looking for a software program to email me if one of the drives goes south.

Thanks all.

Please, how can I reset the password for HP storage Works P2000/MSA2000

Thank you in advance
Dell PowerEdge T620 Failed Disk. The server boots up to a foreign configuration. Asking to select "C" or "F". The system will boot up after selecting F to import foreign config. Server 2012r2 boots up then blue screens critical process died. The system config shows that the virtual disk is offline and 1 disk is ready and 1 is foreign. I am attaching pics of the config page. I have a new drive to install for the one that has the amber light  flashing on it. Any help on getting the RAID fixed and server started would be awesome.

Our network share is on an enterprise class NAS farm with flash and lots of physical drives. We can copy files to and from the network quickly, our performance with large Excel files and large Access databases is abysmal.

After raising the issue with IT, they gave us a test environment on a Windows Server share and it a bunch faster than the NAS drives, but IT considers this "just a test" and "temporary". The project manager in IT that is helping us doesn't seem to know why the Windows server share is so much faster, but I'd like to know why so I can advocate to make our network folders permanently reside on a Windows Server instead of a NAS.

Does anyone know why Windows Server is so much better? From testing I'd say that performing operations like indexing fields on 1mil record tables and such is about 8 times faster and does not suffer from the bottlenecks and freezes on Windows Server that we see on the NAS drive

I own an ASUS laptop with a small hard drive. I bought a large Hard drive to replace it, but was told it could not be replaced. I cannot do anything with the computer because I have no disk space. I keep trying to move things to an external terabyte drive, but I don't know how to move programs to free up disk space. I cannot update WIndows because of no space. I cannot backup my laptop because of no space. My dropbox keeps telling me there is no space. I am not storing document on the C drive. I need to know if there is a way to move programs to an external hard drive, or do I need to give up on this otherwise fine laptop.
I have a server 2012 with a Raid 1 hosting a virtual machine. Total allocated disk is 460 gb and the virtual machine disk space was filled up somehow very fast. Hyper.v machine wont boot as a result. Can I pop another hard drive in that server to reallocate a larger raid disk size to increase the space? If I put a 2tb in there can I somehow fix this?
I have a new LSI 9381-8i with 8-7200rpm  NAS drives running on windows 10 and my throughput is ~ 30 MB/s. If I copy to a single SATA drive on the same system, I get about 110 MB/sec.

Writing to 8 drives in raid 5 should be a lot faster even with parity calculations. Why is my raid set so slow compared to a single drive? Does LSI require some kind of configuration setting I'm unaware of? At that speed my system can't cope with the video feeds I'm sending to it.

Thank you for any help.
Need a new internal 1T SSD (not hybrid)

I have a 2013 MacBook with a 500GB SSD, but I need more space. The drive is 2012 and slower than today's SSD's.

Any suggestions for a drive I should get? I am budget conscious but do not want buyer's remorse once I upgrade to the new drive.

May I please have FOUR opinions please.  I will split the points 4 ways for the opinions.

The question: If you were to purchase a 6 tb mechanical hard drive to be used in a workstation desktop with 256 meg of ram, what brand would you choose and why? It will not be used for constant video use. My computer is a Dell 6810 Workstation with two 1 tb ssd drives and I wish to add the drive I am asking the question about.
Hi all,

I don't know where to begin on this one.

I have an external hard drive which is about 6TB in size. There are hundreds of folders and sub folders on the external hard drive.

What I need to do is delete all folders and the subsequent sub folders and keep its contents and put it all the contents into one master folder.

I did a google search and found an article dating back to 2013 and whe n i did a test it deleted all files and folders.

Navigate to C:\folder and run the following command:

for /f "delims=" %d in ('dir /ad /b') do @rd /q /s "%d"

Open in new window

Is this even possible?
Dell computer will not boot. I have run the F-12 diagnostics and when it hit about 45% of hard drive test it stopped with this error. 0f00:133c No suitable media present. I have tried to run in safe mode, pulled off all hardware but monitor, mouse and keyboard. Still will not boot. I have restore points going back to the start and none work. It seems the hard drive is bad. I need to or hoped to pull the documents off and just re-image but when I sled this to my other laptop, it sees the drive but says no media present? Any way to pull the data or know for sure it is the hard drive? I have run and exhausted all testing that I am aware of.
Hey folks - I'm trying to determine, how Windows creates the GUID for a given disk volume.   What are the various components / sections of a given volume GUID, and what is each section referring too, in a typical hyphen separated volume GUID like this:

Secondarily, and the reason I'm trying to determine this, is to figure out why so often, the C:\ volume GUID ends in "6963" on many Windows installs.   Since GUID's are intended to be largely unique, I'm assuming something with how these GUID's are created, so very often leads to the C:\ GUID ending in 6963?  Which seems like a fairly random number to end with - yet if you google 6963 GUID you'll see how very common it is indeed!  I work with disk images of servers at my job and see the volume GUID's for hundreds of servers per week, and the fact that they're so often ending in 6963 has had me curious far too often.

In fact, multiple of Microsoft's own articles, like this one, contain  GUID ending in 6963:

I have been searching around, and have found very little in the way of an explanation as to how these GUID's are created for disk volumes specifically, and/or why 6963 is so often the ending string, especially for C:\ partitions.

Thank you in advance!
Found this in my Windows 7 Pro x64 computer:

 The first Critical Blacklist Event found: Event ID - 11 System log - Disk: The driver detected a controller error on \Device\Harddisk1\DR1.

This computer only has one hard drive C: which is showing up in Disk Manager as Disk 0.

Could this be caused by someone removing incorrectly a USB device?

Thanks in advance.

So a customer accidentally formatted a 2TB hard drive to NTFS. I used the usual techniques to try a recovery but nothing worked (Testdisk, Ontrack).
After discussing with him it looks like the drive was previously HFS.

I was wondering if this new information can help me? I never tried a recovery from HFS but I don't think it should be very different with Testdisk.
Dear Experts,

I am configuring a Lenovo V3700 V2 with 24 hard drives.

I created two pools.

I added 12 drives to the first pool.

When I want to add the remaining 12 to the second pool, I only see 11 drives.

Where did the missing disk go?
Hi everyone,

We have recently been purchasing Refurbished Dell latitude 5590's from dell and another vendor. I've ran into the issue of the computer randomly booting to a black screen after the dell logo appears. Before this happened I had installed drivers, applications, and the latest BIOS. During a random restart the issue occurs and I am unable to get back into windows. I can not figure out why this is happening on these machines as these are the only one's having this issue.

I have worked with dell on one of the machines. They are sending me a new hard drive which didn't fix the issue.

I am able to boot into safe mode. I'm unable to do a clean boot with minimal drivers. I also attempted to perform a chkdsk command to repair the drive and I got an error message "chkdsk is not available for raw drive" which I thought was odd.

If anyone has any ideas or has experienced this issue with these machines please help.
I now have the Crucial DDR3 , 1600MHz , Non-ECC , CL11 , X8 , 1.35V , Unbuffered , SODIMM , 204-pin, memory for this unit and am now in need a good quality inexpensive SSD drive

All suggestions are greatly appreciated.
I have a Dell Vostro laptop with a 500 GB SATA hard dive
-      My client accidently spilled water onto his keyboard but did not pull out the battery while attempting to remove as much water as possible from the keyboard. He let it dry over night before actually pulling out the battery the next day
-      He let it dry out a few more days.
-      Powered up the laptop and it posted “No Boot Device”. Confirmed the BIOS does not see the HDD
-      He brought the laptop to me
-      When removing the back cover to view the hard drive, I saw some rust and corrosion on the controller board. I removed the controller board to clean off any corrosion on the board and contacts. Reconnected. Still, the pc post shows no hdd connected.
-      I then inserted the drive into a USB HDD dock. The drive would spin, makes a couple of “clattering” sounds but never see the drive
-      No backups
-      He also stated that the laptop has never been dropped

My question is
-      Is it worth trying to locate an identical hard drive and transfer the controller board to the defective hard drive? Like I stated above, the drive does spin up. I’m just wondering if the circuit board is damaged, which I’m sure it is -  is it possible to get the drive to be recognizable by the computer?
-      If not, I will have to send out the drive to a data recovery center
I have an aging internal hard drive, so I'm backing it up with an external. I learned my lesson after losing a drive a few years ago. It's all media: home movies, TV, music, etc.

I store my files in folders like this: (more complicated, but this is the structure)

I don't get around to sorting that often, so there's hundreds, possibly thousands of files in the unsorted folder.  I'm copying the entire drive to the backup as-is. What I would like to do is find a way to sort on the internal drive, and have the backup drive automatically mimic the moves. I don't think I want to use a windows-driven file backup, since I don't want to torture the drive by re-writing the data (it's already worked enough moving 3 TB in the last few days). These are simply index adjustments. (I also alter tags, but I imagine that could be a problem.)

I'd like to have a "system" going forward so as I acquire more media, I can sort at my leisure, and have my backup drive to the same, without having to open lots of windows and move every file twice. Otherwise, when the original drive dies, I'll have all the data, but won't be able to find anything.

Any ideas are welcome. Thanks.
