Kingston USB 2.O Usb drive

Hello,

I have Kingston 2.0 USB Memory Drive. Its working fine with direct file copying. The main problem is when i copy some folders contains many files it saves. But when the drive is connected to other pc, the files seems to be corrupted and could not be retrieved. Now when the direve against connected to the one from where the files are copied then also the files seems to be corrupted.

Kindly guide me on this and how to get rid of this problem

Thanks in advance
