I recently purchased a WD 320 GB my passport studio. It arrived and I unpackaged etc. I then plugged it in using the FW800 port and decided I'd try and copy a large file to the drive to test speeds. Initially I tried to copy from my old WD elements drive which was running off the usb 2.0 It copied for a long while then completely froze my laptop. This happened on several occasions during transfers. I also had the drive fall asleep and 'unsafely' remove itself without any initiation from me. I decided I would reformat and try again. Instead of copying from the elements drive I did it to my main drive and then to the passport drive. Once again errors occured. The drive came from a amazon seller and to be honest it looked used. Can anyone restore any faith in this drive or recommend me another with similar specs.
