Problems when cloning hard drive

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?

 

I put the drive into my mbp and booted off the instal disk to no avail. I rma'd the hd this morning but am a little mad cause I will be without a larger hd for a week or more

 

it failed to instal the OS. But I am sure it is the drive, as I tried to copy files to it and it hang up too.

 

I rma'ed it today and got it sent out. now I have to make the 4gb of space left on my 160gb stock drive last till I get a new one
