It  can take up to a half hour to copy 1 gig. On the case it states 2.5″ Sata USB 2.0 certified

Also, when I copy data to it, a message appears ” Cannot read from source file or disk”.

I put another hard disk in it, but still same problem.

I installed a printer driver on my notebook and after restarting the note book could no longer boot, I tried the safe mode sothat I can uninstall but could not boot from the safe mode. so now I bought a 2.5" hard disk inclosure and tried to convert it to an external hard drive but if I plug it to the usb port it only shows me a red light and PCs does not recorgnize it at all.
Thank u all.
