I had a laptop that went down beyond repair. So I got the HDD and set it as an external 2.5" disk. This disk used to have Win XP and was set with 4 partitions. Yesterday I transferred all the data I had to my new laptop, and everything went fine. Then, I used Win Vista's programs to eliminate the 4 partitions setting the disk to only one volume. Still everything ok. The problem now is... when I try to transfer data from my laptop to the disk, it only transfers small files. With files over 1Mb the computer just hangs up. I ran Scandisk and there were no problems, so I suppose the problem is not with the disk... Can it be the USB cable? But yesterday when I used it to transfer the data from the external to the computer HDD, everything went fine...
