Well, the Cavier HDD in my sig is acting funny. Last night I loaded about 30 gigs of data to it, not that much (its still over 60 percent free). So today I turned on my computer and was using files on it, and all of a sudden it made Windows Explorer stop responding. I thought that was wierd, and had to restart the computer. Well when it started back up the hard drive was working fine, mind you it hasn't been making any noises or anything like a normal HDD that is dieing would. I opened my computer about 30 minutes later noticed that that disk wasn't showing up. I restarted the computer, and the drive was working again, but then about 10 minutes later it just "shut off", if doesn't actually shutoff I can hear it running, but it just stops working with Windows. I read a chkdsk but it said there were no errors at all. I tried to defragment but it doesn't stay on long enough to finish. So do you guys this it's dieing? If so I'll buy a new one tonight.

EDIT- And how can I back up data to another HDD if everytime I try it freezes?
