!!!pease help, anyone!!!

I have 2 Usb flashes, none of them seem to work :(

I haven't used them for 4 days, and now when I attach them to my computer/laptop for one it says that it's not recognizable (4Gb Kingston DT) and the other one doesn't even register (8Gb SanDisk Cruzer). In some computers it turn to be "unknown device" and it is ready for use, but it is not in my computer.

This happened just few minutes ago. I have tried on 3 computers and 3 laptops to view them and the results are the same. The OS on those comps are: XP 32x, Vista 32x, Vista 64x, Win 7 64x...

Can anyone help me with this problem pls? I need these by Monday :(
If any of you can recommend some program for flash recovery it will be greatly appreciated. BTW, the content of those flashes are not in my interest to save but it would be great to save whatever it is on them. Aka, I just need to get them to work. I will try few more times on some other computers.

PS: I suspect that it has something to do with some viruses, but I'm not sure because I cant access it!!!

Thanks again for all future help, and cheers

Most probably you need to update your USB drivers or troubleshoot it (since they can't be recognised). If you think that it is related to viruses, just scan it with any anti-virus software you have.

Thanks.

Well I can't agree on that one because on some OS says unknown device was installed but there is nothing to see and other says that device has malfunctioned!... That is for this one that can be 'seen', but what to do with this 8Gb San Disk, Can't even register him that even exist in system?

*stupid flashes XD*

There must be some other explanation than they have start malfunctioned both at the same time. That is like 1/1000000 chance you must admit.

I will try to update my drivers but I sincerely doubt that that is the problem. Other flashes work fine . Thanks anyway, if you think of something else please share with me. Thanks...

Cheers
