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.
