Well I received my wd scorpio blue and tried to clone my original 160 gb hard drive. I can get the drive to mount and erased and formated but when I try to clone, it stops at 21.5mb copied and then after about a minute, it says that the drive has been ejected improperly and gives me that warning. I have also tried to just copy files over to the hd and it hangs also. Could this be the drive? I am using a brand new external enclosure also. Any help would be appreciated! for reference, I have reformated and erased the drive multiple times and taken out the drive, made sure it is seated, restarted the computer, and all to no avail. so any ideas? EDIT: I tried to mount the disk on windows and format and it would not allow it. So now, I will try to do it via the osx disc and the hd in the computer. any other solutions?
