My toshiba pen drive is now 4mb and i'm really freaking out. I have tried everything from easeus partition master, testdisk, hp usb disk utility. I've searched the entire web for help and nothing has worked. I even tried diskpart. When i go to the disk manager, there are no unallocated spaces. It's just the 4mb. I REALLY REALLY need help!!!

Sounds like a hard failure. If that is the case there isn't very much that can be done, you have tried, nearly everything we could suggest or a variation of it. Hopefully you have backups.– RamhoundJul 14, 2015 at 13:18

@RogUE - I don't see how that could possibly be a duplicate of this question.– RamhoundJul 14, 2015 at 13:19

@Ramhound Why can't it be a 'fake' drive as mentioned in the dup?– DavidPostill ♦Jul 14, 2015 at 13:22

@Ramhound: Question is so annoyingly lacking in detail, that it may be a duplicate as marked by RogUE. No mention if drive was used before as 16 GB, no mention what he did with all that software listed and what not worked...– AcePLJul 14, 2015 at 17:59

It may be one of two things.
It may simply be defective, though assuming you have used it without issue in the past this may not be the case.
It has a corrupted filesystem, which would unfortunately require a format and erase any data.
If you suspect it is neither of these, it may need to be replaced unfortunately. It seems that you have already run many of the tests that I would have run.
