Question about Acomdata (HD250UE5-72) (HD250UE572) 250 GB Hard Drive
I have an Acomdata PHD250UHE-54-LS external hard drive. I bought it in August and it has worked great however I now got the message telling me that I must format the drive before I can use it.
It doesn't show any files.
I do get a G: prompt.
The unit is humming as normal.
The light is blue (normal).
How do I get my files off of the drive and what should I do?
a 6ya expert can help you resolve that issue over the phone in a minute or two.
best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

I have the 250 GB Acomdata drive. Had the exact same problem--computer would not recognize drive; blue light on drive lit and drive making a slight whirring/clicking noise. I read somewhere that some people that have had this problem have found the problem is with the USB interface between the drive and case, NOT with the drive itself. I took the drive out of its case and installed it in a desktop computer and was able to get all of the data off of the drive.

This generally means you have a hardware failure in the drive or enclosure. The simplest way to test which is to have a hardware tech move the drive into a new enclosure and see if it works.
This will void your warranty if you do it, so, if the drive is under warranty and there are no files you consider valuable on the drive, call the manufacturer for warranty support.
If you value the data more than the drive is worth then take it to your local hardware vendor and ask them to test the hard drive in a new enclosure. Good odds it will work this way but if not you may need the help of a data recovery specialist.
In North America I use Armor-IT, if you are in a different region and the new enclosure fails to garner results, comment back with your region(Country, State, City) and I will supply you with the closest reputable facility.

Remove the drive from the enclosure and either install it in your machine as a slave or you will need to buy a new enclosure and put the drive in it.

Hello there Mansoor.
First, I have to commend you on how clear and extremely well articulated your problem is presented. You give every detail necessary to grasp your current situation. Good job! I can also clearly see you're at least a fairly proficient user. I only wish I'd reviewed your question before now, so I could have replied sooner. That notwithstanding, here's my GEEK-steer ...
Good job testing the drive against other "known good" systems. Because (as you probably already know) based on that, it's a virtual certainty it's the drive itself that's the source of the problem (UNLESS you used the same USB cable in all tests ... rule that out by using a "known good" cable). Its trouble could be caused by any number things [e.g., deleted partition, virus related, "sector" (file/folder structure related) errors, etc.]. At this point you've utilized all the tools that Windows avails you to work this problem (e.g., you obviously can't perform a Windows "chkdsk" on it unless there's an assigned and known driver letter, "Disk Managment" was no help, etc.). We therefore need additional software tools in order to proceed further.
Per the manufacturer's webpage, "Acomdata does not have any Windows XP, Windows Vista or Mac OS drivers because all products use the built-in driver support already supplied by the associated Operating System". Therefore, they design all their devices to be supported by Windows' database of generic drivers. However, here's their offered driver package for "All Platforms". It's a long-shot, but it couldn't hurt to start by giving this driver a try (you can always "Roll back driver" from within "Device Manager" if necessary).
== CAPTURE AN IMAGE BACKUP ==
If, as you state, data recovery is of the utmost importance, then I would strongly advise your very first objective to be (if at all possible) creating an image of the problem drive, then backup that image onto another drive. I would do that FIRST to lock in it's current state as an insurance policy, BEFORE I ran any testing/diagnostics, or attempted any alternate means of data recovery. Keep that image intact throughout this process until resolution. There are several disk image "Backup Tools" (e.g., "DriveImageXML", "Acronis True Image", etc.) in "Hiren's Boot CD" you can use to accomplish this.
== BREAK OUT THE TOOLBOX ==
Refer here for complete list of its available tools. There are far too many to cover in any detail here. Particularly when the nature of your problem is yet known, as each may, or may not be THE one for the job. However, you can simply Google each to obtain background and usage instructions. Also, tools reside in either the DOS or mini-Windows boot portions of the CD, as some are DOS executable and some Windows. You may have to venture into both until you find the tool that works for you. I know there's a lot in that puppy, but that is intentional because it's a good thing ... affords wide range of choices/options.
== HOW-TO CREATE 'HIREN'S BOOT CD' ==
Next I would attempt recovering the data using any number of Hiren's "Recovery Tools" category of tools (e.g., "ProSoft Media Tools", "GetDataBack for NTFS", "TestDisk", "Ontrack Easy Recovery", etc.). Many of these include diagnostics/repair facilities you can use in the course of your recovery efforts.
== RECOVER/FIX THE DRIVE ==
Then once/if you've successfully recovered the drive's data, you can (if applicable) use any number of Hiren's (hard-drive related) "Testing Tools" and "Hard Disk Tools" categories of items in order to fully test/diagnose and hopefully recover the drive to working order.
Good luck, and please do post back to ...

Tips for a great answer:
you might have to designate your acomdata drive to just your windows 7 computer
you might have format it on your windows 7 machine
then use it only with this computer
have had similiar problems using usb drives with both xp and w7
althought where of large capacity usb data drives
if you have any important data you want save it to a smaller capacity usb data drive then transfer it to your w7 acomdata
A few important bits of information about using faults and possible fixes on usb drives
click start control panel administrive tools computer management device manager scroll down universal serial bus controllers you could see a yellow question / exclamation mark? ! or a red X
you will need to update/reinstall drivers
right click to reinstall drivers
if you can see your usb drive but its not working
ports(com&lpt)right click update driver if this fails to fix the problem
check the USB leads that attach to the motherboard usually red white green black make sure they are securely seated and have no dust build up on them dust will cause static and a lot of unforeseen problems for a computer and its parts
click start control panel administrive tools computer management disk management right click on your drive select properties click tools you should see click check now click start two boxes automatically fix files and scan for and attempt recovery of bad sectors place then a tick in one box then select check now start or you might tick one box then return after its finished the first repair then return and tick the second box
(I have found better results ticking the first box then reurn and tick the second box) you should not do anything while the chkdsk utility is in progress any input may damage this drive also you might need to do this
click start click to open on my computer you should see your usb drive F: right click select properties there will be an array of options select the sharing tab option then advanced sharing
permissions make sure you have a tick in the share this folder box then click permissions make sure all three boxes are ticked you full control change and read in windows 7
click start control panel user accounts click on the administrators account if And finally, click Allow next to Full Control.
hope this helps you
