backing up a tivo A drive to a partitioned drive?

First off, I just brought a refurb 14hr tivo so I am a newbie at this. I read the tivofaq as every newbie should do and I came across a problem. The drive I want to backup to (a 27 gig) is partitioned into 2 drives, a 7 and a 20. It seems when I backup the tivo drive using dylan disk and "dd if=/dev/hdc bs=32k | gzip -9c | split -b 650m - /mnt/tivodisk_" (no quotes)." it would backup on the 7 gig instead of the 20 gig (at least that is my assumption why it would give me a no space left error). Should I proceed and use the 2nd prompt command in tivofaq (section 2.18 step 6) which suppose to fix errors or is there a way to make it backup on to the 20 gig?

Actually, where the command saves its file to is to where "/mnt" points to.

Before you can execute that command, you have to execute a "mount" command to tell Linux that you're going to attach another filesystem to the file hierarchy (all filesystems are descendents of the root filesystem). You have to determine where your 7GB and 20GB partitions are located on the hard drive -- e.g., hda1 = 7GB, hda2 = 20GB, or vice-versa, or even hda1=7GB, hda5=20 GB or vice version (depending on whether they're regular physical partitions, or extended partitions).

When you boot DBD, you'll see something like (but possibly not exactly):
Partition check:
hda: hda1 hda2 < hda5 > ...
listing all the partitions. If a partition is located within those angle brackets (hda5 in this example), it means it's an extended partition, and one of hda1 or hda2 is unmountable.

Best bet? mount those partitions and see. do a "df" and see how much space is listed for the /mnt mount. If it's 7GB, then umount /mnt, and mount the others. If you get an error mounting, try another partition (you may have run into an extended partition).

I kind of figure that out eventually, but only after I plug in a empty 10 gig drive to backup the 14 (hoping the 14 is not completely full). Fortunately, it wasn't. It was only 7.xx gig (about half full). I heard horror stories about how the refurbs usually have the drive full. I am just wondering now do I have to backup again because the tivo isn't updated yet.

I would recommend backing up 2.0.1. If you don't hook up any video source, the image size should be about the same as what you have now.
