Hello and thanks in advance for any help :) .  I've an ADATA S102/64GB USB3.0 that from one moment to the next went from functioning properly to needing-formatting-but-the-formatting-can't-be-completed.  Using various tools (Windows 7 64bit Home Premium) the drive either doesn't populate in My Computer or shows as unallocated or raw; attacking with Disk Management, DiskPart, or numerous third-party partition managers hasn't worked; using a friend's Mac didn't solve anything; and GParted from several different Linux distributions all failed to format the drive.  My question:  is there any way to actually learn whether or not the flash drive can be saved?  That is, is there a utility (preferably freeware ;) ) that can diagnose the problem to the extent of "It's Dead" or "Do This"?  It seems to me that there's no physical issue with the drive since the stem is intact and it receives power from the USB port; and yet, nothing I've tried has solved the problem or even given me an idea of what the problem is.  I'm far from expert, but a dozen hours of effort has left me scratching my head and I'd really be pleased to be able to at least toss the drive in the trash knowing for certain that it's not fixable.  Thanks again for your time.

Hi,

 

Depending on the chip used there are tools specific to format the drive and make it work again if not damaged or is fake!

 

Download USBDeview http://www.nirsoft.net/utils/usb_devices_view.html that matches your OS (32 or 64-bits), run the tool with the flash drive connected and post the VendorID and ProductID

I can't say this will work for you but AData has there own repair utility for drives that cannot be formatted. I believe it reflashes the drives firmware. You need an internet connection to do the repair and it may not detect your drive. If under warranty I would contact customer service and RMA it.

LouieChuckyMerry try the tool suggest by JohnC, see if it works for you.

 

 

Finding the correct tool for the Controller could be difficult...

JohnC_21; SleepyDude:  Using the ADATA link worked, although I lost a GB+ (perhaps due to Dead Sectors?) when all was clicked and formatted.  Not a problem.  Thank you both very much for taking the time to teach an old dog some new tricks; I really do appreciate it :) .  Be well.

Good not a complete lost. :)

 

Just to be safe I would test the flash drive using http://www.heise.de/download/product/h2testw-50539 (interface can be changed to EN)

With the flash empty of data let the program read and write files by filling completely all the space on the drive, if there is any problem it will fail the test.

I tried H2testw earlier in my attempt to repair the flash drive, so I've a copy handy to run the test.  No errors reported, all seems well.  Thanks again for your help, SleepyDude :) .
