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.

Just for full disclosure, I've already posted this question on the Western Digital community forums, but I've come to value the level of contributions and input from the Experts' Exchange, so I wanted to share my experience here to see what else I might hear from any of you.

Recently, I discovered a disheartening problem with a piece of my equipment, and the prospects for straightening it out aren't great, based on my own research. Long story short, I have a WD Passport portable hard drive that has been working pretty decently for the better part of the last ten years since buying it at my college's bookstore. Unfortunately, I had a mishap while my device was in transit: carrying it in a box up a staircase, it started to slip out as I got up the stairwell; I managed to make it to the top in time, but the hard drive fell out just as I got past the threshold of the door. My intent was to hurry inside to carefully set the box down, or at the very least have the fall be cushioned by the carpeted floor rather than have it tumbling down the hardwood staircase. It seemed pretty harmless at the time, so I didn't check it immediately that night. but over this past weekend, I needed to hook it up to my computer, and I found that it wasn't working anymore. I immediately did some online digging and found that this is pretty common; not only that, I've seen WD

Trying to restore data from a NAS drive. So i have this Bufalo NAS Terrastation, and the fan died, so i am trying to recover the data from, usually, i just use something like knoppix, but when i boot Knoppix up with drives attached, it doesnt see the drives, it must be something to do with the Raid thats installed, i can see the drives in the BIOS no problem and they have passed all tests ( i was worried with the fan not working they may have overheated)

Hi,

 I am considering HP Proliant ML110 G10 server and like to buy 2TB SSD hard drives.
 Must I buy HP branded SSD hard drives or enterprise grade SSD hard drives made by ntel/Sandisk/Samsung work work?
 The reason for buying non HP branded SSD hard drives are because of lower costs.

Thanks.

Do you consider it ill-advised to install firmware updates on a hard drive? Context: We have two hard drives on our Dell PowerEdge R710 that aren't officially backed by Dell. We could install firmware for those but are afraid they will break and because Seagate, the drive brand, doesn't like the idea. We keep getting media errors on those hard drives even though the RAID 5 server is running drive and there are no other drive issues. Thoughts?

I am trying to copy over a photo library approx 14GB from a mac hard drive connected via external usb connection to my desktop on my macbook.
The hard drive keeps freezing up whenever I try to copy it via finder. I also tried to do first aid on the drive via Disk Utility. My guess is that the hard drive is very close to failure but I can browse the files and folders. How can I get these photos recovered?

Im interested in what peoples experiences with replacing the hard drive with an SSD are like, this is for a Win7 64bit machine using a SATA interface,
currently the drive is a 1TB partitioned as 50:50 C: and D: drives, with programs on C: mainly,  my questions are:

1) Reliability - i believe flash memory has a limit on number of re-writes, so will an SSD eventually become corrupted?, is the SSD lifetime comparable
to the trusty mechanical Hard drive?

2) The machine only has 2 SATA interfaces, one used by the CD/DVD drive which i rarely use, is there a way to keep the HDD installed so
it could be used as some sort of quick backup device?

3) What sort of speed improvements are likely on boot up time, and what software would you use to install/ copy over the existing hard drive info?

4) Could a 500GB SSD be used just for frequently used programs/data and the HDD for archive info?, or is the idea to throw away the hard drive when you
install the SSD?, or do you need the same size SSD drive as your existing HDD?

Many thanks for your help / experience !

Hi,

We use Seagate STDR5000200 external hard drives for backing up our data on our systems each month.

These systems we backup data for would include Windows 10 Pro, Windows 7 and Windows Server 2003, all systems are using BIOS.

The Seagate STDR5000200 external hard drive we have contains every piece of data for our business such as databases and Microsoft office files.

We prefer to keep our external backup drive portable so that we can bring our external drives offsite.

This drive is replaced each month at a time by another drive which contains backup data where we switch between two drives each month backing up our systems.

These external hard drives are formatted as NTFS.

These drives are recognised by all our PCs.

We have had a problem with these Seagate external hard drives where, if we have a backup running and the power of our PC goes off, the drive becomes corrupt and we lose our data.

This has happened with our Seagate drives more than once.

What would be the best external hard drive to use for backup of our system's data that is fail safe and portable?

Thanks,
Robbie

Hello,
We have a raid 5 cofiguration, and running out of space.  It is on a dell server r620 with perc h710 mini (embeded) controller.  If I were to replace one hard drive at a time to bigger size and let it rebuild .. will I be able to increase the size of the volume on the raid without having to backup and restore?

I have read contradictory information and I want to make sure, for example below is a link that gives step by step on how to achieve this.

so using hyper backup to backup files from nas to external harddisk.

currently, backup fails- because no space in destination.
i have posted the pic of current config of the rotation policy. can someone pleas have a look at it, and let me know what needs to be changed, so it deletes the oldest backup automatically and creates space for new backups in future.

I am trying to reset the IP address and the superuser password to defaults for a V3700 IBM Storewize using satask commands but to no success. No one knows any of the storage IP addresses at the moment. Hence the need to reset them to default.

 I do not have the initialization tool that is normally shipped with the storage in a USB drive. I cannot download the tool either because it seems it requires the storewise to be associated with some warranty or IBM hardware support contract for the download to continue. Anyone who has the initialization tool, you are welcome to share it with me. Otherwise i would like some advising on the use of the satask commands, especially their syntax.

Backup Solution?    I've read so many reviews/articles on backup solutions and software, that my head is spinning.   We are a very small company and have three servers:
SBS2011 which has the AD, Server 2008 R2 (SQL); and Server 2008 Standard (DATA files).   We would like to do a full backup weekly on the SQL and DATA servers with daily incrementals.   There is a docking station hooked up to the DATA server that I manually change out the 3Tb hard drives daily.

Can you recommend a solution?   Our budget is small and our needs are simple.   Thanking you in advance.

AWS Snowball help.  

We received an AWS snowball and I'm trying to make it work.  AWS support SUCKS with a capital SU, so, here I am.  :)

The snowball is connected and pulling an IP.

Problem one is that the LCD screen on the front does not show that it has an IP.  The LCD screen is showing that the device timed out and I need to try again.  However, in my DHCP leases, I can see the IP and the DNS name and I can ping it.  So, I figured the LCD screen is wrong.  Maybe...

Second thing is the CLI snowball start command.  I downloaded the manifest and the unlock key and I "think" I have the command written correctly, but it's failing.  It's telling me it can't find the manifect in the path I specified.  Here's the command I'm using:

snowball start -i 192.168.0.53 -m c:/snowball/JID54a9420f-455e-462b-8d8f-caecc2be40a3_manifest.bin -u 8aaaf-8febd-xxxxx-b580d-xxxx

Notice my path...it's to the location on my C: drive where the manifest file lives.  The message I get is that the client cannot communicate with the snowball.  However, as I said, I CAN ping it.  

Anyone have any experience with these things?  At this point, it's a brick.

Thanks

is there a way to disable Windows Update on Windows 10? I have mini-pc that has 16G hard drive, only serves run one slide of powerpoint, nothing else. Every so often, the Windows Update ran and trying to install but fail due to the no storage available.  Whenever it failed, the windows screen filled with asking for troubleshooting.  I googled and tried many things differently, but all failed. Any idea?

I have a server 2008 r2 that has a software raid 5 with 4 drives.  I have one drive failing and need to replace it.  Its not in a failed state yet but senses it is failing.  I have seen several horror stories on the process and and want to ensure I get it right the first time.  What is the correct process to do this?  I do not have a extra drive bay so I will have to pull and swap.  Do I need to do this with the server off or do a hot swap?

Again, I don't want to get in to the situation where it is not recoverable and need to know the correct steps to take.

Thanks in advance.

I am having problems with a RAID 5 setup utilizing 4 x Samsung 850 Pro 2 GB SSD SATA drives. Intel RST version 16.5.1.1030. Server = Compulab Airtop. BIOS version ARTP-3.1.0.637.5.0 (set to RAID mode).

Everything appears to operate correctly in normal operation. However, I have recently been running a scheduled Verify & Repair operation from the Intel RST utility. The first time it was run it reported over 50,000 errors that were repaired and thereafter each night I get 50-60 errors. The system reports no physical hard drive errors and Chkdsk on the RAID drive also give no errors.

Can anyone help? Many thanks.

Hello,

Is there a way to measure the connection speed of a peripheral/external hard drive.

For example, I read that a USB-2 connection has a speed of ~60 MBps and a USB-3 connection a speed of ~640 MBps. But is there a way to check the exact speed (eg ping the hard drive)?

Thanks
