I have a DSR6000 that exhibits no problems whatsover. It's been running with 2 80 GB drives since August 2001, but the A drive was simply a mirror of the original 40 GB drive, i.e., only 40 GB was used. Today I decided to activate the 2nd 40GB of the A drive with MFS Tools.
I started by doing a backup. While the backup was taking place, I got a bunch of unrecoverable sector errors all on LBA 44533970. This sector is in partition 10, the first MFS Application Region. (partition table below).
I'd like to preserve my recorded program yet still fix this problem. Any ideas? I'm going to delay running mfsadd until I resolve this.
I ran PowerMax on this drive and it did find a problem and offered to fix it; I assume by remapping the sector. If I let it do this, I'll end up with a sector in the MFS application region that's unitialized. How destructive would this be? Can the TiVo software recognize and fix this sort of problem?
Any other ideas would be appreciated.

Here are the actual errors I received. Had to write them down and type them back in even though I sent stderr to a file (anyone know how to capture these errors to a file?)
hdc: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hdc: dma_intr: error=0x40 { UncorrectableError } LBAsect=44533970, sector=44533736
end_request: I/O error, dev 16:00 (hdc), sector 44533736
This repeated over and over with the LBA being constant and the sector sequencing from 44533736 to 44533970 (even only)
