Seagate 7200.12 Not Recognized by System

So a friend of mine had a Seagate 7200.11 drive die on him (which, after investigating, is no surprise at all). He had backups, so I told him to go get a new drive, and I'd take care of the restoration.

He shows up with a 7200.12. I put it in the PC and the onboard SATA controller doesn't recognize it at all. I change ports from SATA0 to SATA1 and still nothing.

I throw it in the enclosure for his backup drive and plug it into my Macbook. The Macbook sees it right away and allows me to format it as FAT32. So the new drive is apparently good.

I plug his backup drive into the PC, and the SATA card recognizes it. Windows Setup doesn't, but that's another problem. I try putting the new drive in and switching the SATA from 'RAID' to 'IDE' to see if that helps, but no go.

The new drive seems good, but the desktop PC just won't read it.

Solution 1:

Have you run Seagate's drive tester tool on it? Have you checked any jumpers on the drive and verified they are set sanely? Have you checked your system's BIOS to make sure the SATA controller is enabled?

I don't think that drive actually has jumpers, but you should check if you haven't already.

I have an older system with a SATA-1 controller that won't recognize my Seagate SATA-2 drives right off the bat, but I haven't taken the time to figure out why. (They're the Green drives, not 7200.12's. They were installed into another system, so there wasn't a need to diagnose the issue.) Some Western Digital SATA-2 drives include jumpers to force SATA-1 mode, so my suspicion was that the Seagates don't fall back to SATA-1 correctly. SATA-2 is supposed to be backwards compatible, but it wouldn't be the first time a newer tech didn't make good on all its promises.

Is this your jumper pinout? Verify with the drive's label or manual and set that jumper if present:
