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 ...

SOURCE: Hi, I cannot find my
The scary part is that you TRIED AN OTHER POWER SUPPLY was it the same VOLTAGE??? aws it the same AMPERAGE/WATTS??? was it the same POLARITY??? You could have dammaged the device if you did not respect the power ratings... IT'S NOT JUST A MATER OF PLUGING IN WHATEVER FITTS... You can buy a UNIVERSAL POWER SYPPLY but it has to meet the same VOLTAGE, AMPERS (WATTS), the same POLARITY (tip POSITIVE or tip NEGATIVE) etc... hopfully if the device is not dammaged, bring the storage device to a good electronic store and ask for a equivallant replacement meeting the EXACT power ratings on the device... if it works JUST PRAY GOD THAT YOU'LL NEVER DO THAT AGAIN, if it don't than you've busted the unit, DONT PANNIC you can still recover what ever is on the drive by taking it out of the enclosure and connecting it to a desk top PC via a SATA port and recover the DATA, as for the rest (USB CONTROLLER) than throw it away in the garbage...
