    THR22-100 Partition Table

    Not sure where to post this but want to see what's on the new THR22 DirecTV with TiVo DVR's and need some help as things have change so much from my DTiVo days. So far I have been able to dump the partition table.

    sudo ./pdisk.x86 /dev/sdb

    That would confirm that the OS is not on the hard drive. The MFS partitions are obvious, as are the swap and VAR partitions. The interesting partitions are 6 and 14.

    From what I've been reading, partition 14 was new in the tivo premiere. I'm trying to come up to speed on the current partition table of the Premiere to compare with the THR22 as there seems to be some common changes here.

    I also don't recognize the "10: MFS MFS application region" but my memory fails me. So the RSRVD areas are probably place holders for the non-directv Tivo's 2 kernels and 2 other partitions?

    So far all I've found of much interest is the log files. I'm probably wasting my time but what the heck, lol.

    It's been a while since I ran pdisk, but it seems to me partitions 10 - 13 are the same as those found in the Series II DirecTiVos. That's where the recordings and other information are saved. Certainly they are the largest partitions.

    Partition 14 looks the same as the Premiere. It appears to be a SQLLite DB now used for guide data. Not sure what partitions 6 and 7 are used for. Would be interesting to mount them up and see what is inside.

    I just let the dvr run long enough to initialize the esata drive and I pulled it pretty soon after it acquired and started downloading. tried this many times until tivopart found the above. May have been operator error not running sudo before tivopart. Was also trying to do a 'graceful shutdown' since I wasn't sure if I was going to see a XFS or Tivo partition table.

    Any idea where the serial port is on the (T)HR22? probably on the motherboard?
