I also said I found bad sectors on it.
Well, which is it?
The more specific help you need, the more concise/accurate information
you need to provide.
So it could be that the mbr had a bad sector that was not used when
I tested it as an aux storage device. That would mean that it might
not show up as a drive in the dell but would work fine (as long as I
didn't use a bad sector) for storage.
Go for it.
The fact that your drive isn't causing the error message should be
clear by now. Considering the fact you just bought a new drive and got
the same error message. And taking into consideration your previous
statement about the first drive that was producing the same error
message your new drive is producing, that the first drive "works so
well in my system".
Apparently the error message is being caused by something other than
the hard drive.
