flash-drive

My friend saved by his works onto my flash drive which was detectable/openable, but ...

The very next day, the drive wouldn't show up in My Computer and Windows gave him error code 43 (Unknown device).

I tried others few systems that once detected his flash drive but the problem still persisted. I don't know whether or not his flash drive is damaged but when plug/un-plugging, there are still sounds coming out though.

Tried solutions:

On Vista Home Premium (his computer): Uninstalled --> Restarted computer --> Re-installed (ERROR 43)
On Windows 7 (my computer): Uninstalled --> Restarted computer --> Can't install (ERROR 43)

It seems that my computer (Windows 7) had the lastest drivers already but still can't detect it.

Its a Kingston DataTraveller 101 (DT101) 8GB.

Could unplugging the flash drive without clicking "Safely Remove Hardware" have caused the problem?
