My backup hard drive was running very slowly during a backup so I stopped it and tried to open Disk Utility to Verify the drive. Disk Utility couldn't find it and froze. After ten minutes I force quit Disk Utility and moved the drive out of my FireWire enclosure to an internal bay within my MacPro. The drive doesn't show on the System Information (SATA) section and System Information seems to check forever. I downloaded SmartReporter which lists the drive as good. It was FAT32 formatted but doesn't show up on anything except SmartReporter, everything else that looks for SATA drives looks forever without finding it.
I think the drive might be OK but is there any way to get into it to reformat or verify it? I've tried Terminal commands (e.g. DiskUtil) and it gets stuck too.
Any suggestions?

Just used Data Rescue II to check the drive and it read it right away although it seemed like the drive ran very slowly. I don't need to recover any data off the drive, I just need to be able to use it for backups. Maybe it's dying, not sure. Last time I had a drive fail, the S.MA.R.T. told me it was failing beforehand.

I left DiskUtility to run for a couple hours and it identified the FAT32 drive to be messed up. I reformatted as HFS+ and all is fine

I wouldn't trust that drive if I were in your position.

Just to add a comment. I had HDDs fail even with "verified" smart status, so the smart status is a doggy method of judgement

I just did a backup of 136GB of data onto it (took little over an hour which is normal). I really think that the drive just got corrupted (it was FAT32). DiskUtil had to run fsck32 to check it which made it really slow. Weird, but I'm willing to run the drive through it's paces and see if it is reliable. I am cautiously optimistic.
Edit: Forgot I had TechTool...running it to see if it says anything...
