I have a HDR112 that has been working nicely for the past 12 years (bought it originally on August 23rd, 2000). A couple of weeks ago it stopped working, and I suspected the HD was bad. This is the 3rd hard disk that I used for this unit, a Maxtor 120GB that I put in it 4 or 5 years ago. I can replace it with a virgin drive, but I'd prefer if at all possible to recover some shows from that drive so I'm first trying to make a copy with all streams on it. The drive isn't dead, it powers up and spins. However when I boot one of the upgrade CDs (so far I tried the LBA48 CD from ptvupgrade, and also the MFSlive 1.4CD) it shows as exactly 20000 sectors, 10MB. It acts as if it were locked - which is weird, as none of my TiVos had locked a drive before. Long story short, I mounted the drive as secondary slave (/dev/hdd) and used diskutil -u 3 on it. It reported that the operation was successful, but now after power cycling the drive shows as 0 sectors, capacity=0MB. I'm out of ideas, and thought I'd better check here before doing anything else.
