Re: Format USB drives - best software?
Is it an SSD, or a regular HD? And how important is it that the info isn't recoverable?
For an SSD, you should use the drive manufacturer's own tool. Usually called Secure Erase.
For a regular HD, right click>format should do the trick for Vista and later OSs(do not check the quick format option). You can always use a hex editor and check that it did, in fact, write all zeros. If your drive has bad sectors, though, you won't be able to access/overwrite the data on those sectors.
