Hey, I bought this hard drive and it was working fine, however I always kept it plugged into my laptop. One day, I removed the hard drive for a while and when I went to plug it back it, it didn't appear. I have notice that when the drive is plugged in, the light is on and I can here it spinning but nothing appears in "My computer". When I remove the drive, I message pops up saving it needs to be formatted as if it was still plugged it. This doesn't work. I have tried to change the lettering of the of the drive but whenever I plug it in, this program crashes. I have tried it in another Toshiba laptop which also runs windows 7 and it doesn't work. I have also tried it in an xbox 360. It seems that whenever I run a program relating to the drive when its plugged in, it causes the program to crash. Please can anyone off any advice? I spent £50 on this and I'd hate for it to be a waste. I bought it online but not form the official site, I don't know if I have any documents of this purchase so it will be hard to return. Any help please?
