I took my iMac into get my HDD replaced. After 3 days, I got a call that my iMac was ready to be picked up and my HDD was replaced. When I look in the system profiler information, I get this as my HDD number: ST31000528AS I asked what HDD they would be replacing it with and they said most likely a Western Digital, but if not, a Hitachi. That doesn't look like either one, it looks like another Seagate. Am I missing something here? Edit: I was looking at Newegg and many people said that this drive they put in my iMac fails a lot. Very mixed reviews don't have me feeling well about the "new" drive.
