I moved a lot of files on and off an external drive. So, I ran Tech Tool and did the Directory thing and the Optimization thing.

The drive will not mount now.

What is weird is, the external drive has my "e-drive_ on it and I can boot from that, but I can't mount the external drive as an external drive.

I hooked the external drive up to another Mac, and it shows up as an "e-drive" but the original volume still will not mount.

Any tips? No errors were ever reported?

10.3.8 on my main machine, but no problems previous. The other mac is running 10.3.6.

Thanks!

That sucks. And I was strongly considering purchasing TechTool. You can try Disk Utility but it probably won't help. Get Disk Warrior if you don't have it; if it can't fix what TechTool broke nothing can.

Yeah, if I don't run these utilities, I lose drives. If I run these utilities, I lose drives.

I've had my G5 for about 14 months. Lost an internal Seagate SATA 160GB and now an external Seagate 160GB.

The internal just failed to spin up after I went out of town for a week and turned the computer off.

The external was always fine until I ran Tech Tool on it. It prolly still works, just I have about 130GB of stuff on the drive.

I'm at wits end. I prety much have to run RAID on everything? Hard drives remain the the physical weak link in the computer.

Tech Tool unmounts the drive to optimize. It has failed to remount since. I used Diskwarrior on it, the drive showed up as a drive I had named it about 6 months ago. Weird eh?

Anyhow, I'm going through data recovery steps now. Basically, it seems like Tech Tool screwed up my directory structure or the journaling. The drive is ok, the data seems hosed at this point. Argh.

I just noticed that the "Journaling is invalid" No I'm running Recovery on it, and it looks like... it's gonna take about 1 week to complete. Sigh.

TechTool is bad news. It killed my PowerBook's hard drive...............twice.

After the second failure I chucked it into the trash can (but not before giving it to my gf to use it as a drink coaster, drawing on it, and scratching it) and picked up a copy of DiskWarrior. Best move ever.
