backup failed

I am experimenting with the MFS 2.0 on an older Tivo before I actually go ahead and do my real one. It is an HDR312 ( single 30 GB hard drive ), I have tried to back it up using MFS 2.0 and Hinsdale's instructions, however after I start the backup, it gets to about 15% and then fails. It reports this:

Source drive size is 30 hours
Backup Image will be 30 hours
Uncompressed backup size: 1849 megabytes
Backup failed: /mnt/dos/tivo.bak : Success
/mnt#

Additionally, when I first mounted the dos drive, I had to mount /dev/hda1 instead of hda, any idea why that would be?

Thanks in advance

John

hda is the whole disk (starting with the partition table), which is what we want MFS Tools to work on, but makes no sense to Linux. hda1 is the first partition on primary master and that contains a filing system that Linux can read.

hda is a mis-print in some older (but widely available) copies of Hinsdale. ALWAYS work from the latest copy, particularly if you have newer model of TiVo.

I had the same problem today. I am trying to install Airnet on SVR-2000. I burned a CDR of the MFSTools 2.0 image, and booted it. It loaded fine.

I have one configuration anomaly. When I opened my tower, I noticed my CD-ROM drive was a master as OEM on the secondary IDE. I tried resetting it as the slave, but it wouldn't boot. I rejumpered the TiVo A drive to be a slave, and substituted 'hdd' for 'hdc' in my command string.

I saw this:
Source drive size is 30 hours
Backup Image will be 30 hours
Uncompressed backup size: 972 megabytes
Backup failed: /mnt/dos/tivo.bak : Success

I noticed that the progress bar never got above 11%. I'm not familiar with UNIX, so I only tinkered with the commands a little - but to no avail.

Worse still, I tried to boot the Airnet Install Software image which I burned to a CD from Silicondust.com's image (can't link to it here, because I'm a n00b). I was hoping to try the MFSTools 1.1 on that disk.

When starting from the Airnet CD, I get to the available boot options, and hit enter. (Other options produce same result.) During the Linux load, after it installs the drivers, it says this:
RAMDISK: Compressed image found at block 0
Kernel panic: Out of memory and no killable processes...

I thought maybe the Airnet Install image was corrupt, so I redownloaded it, burned it to another CD, and got the same result.

So I have a corrupt installer, and an unbackupable TiVo drive... I would really appreciate some guidance here.

HI Robert,
Ok, I'll ask, where is the latest and greatest copy of Hinsdale's instructions?

Thanks
John

How did you mount the partition you're writing the backup to?

If you do ls /mnt/dos do you see the files from your C: drive listed.

Hindsale has a post at the top of this Forum that links to his How-to.

Robert S: I only saw a few files which I didn't recognize as my C drive. There was a config.sys and Windows-like files, but there was no directory structure or anything. There were no other drives than the C, TiVo's A, and the CD-ROM - what else could it be?

Try mounting hda2 or hda5 instead of hda1

Oh, I forgot to add: I had printed out Hinsdale's instructions and followed them to the letter (save the master/slave swap on the secondary IDE chain).
