mfsbackup fails after 91%

[themonk]

Hello,

I've just taken my drive out of my Tivo to create a backup after a recent failure but I'm having problems with mfsbackup.
It's a 300GB Maxtor drive and I'm using the latest ptvupgrade CD to boot from which has lba48 support. The Tivo drive is connected as sec-master and I have a 30GB FAT32 drive as sec-slave.

Thus:
mkdir /mnt/dos
mount /dev/hdd1 /mnt/dos

mfsbackup -l32 -1so /mnt/dos/tivo.bak /dev/hdc

I then get the message:
Scanning source drive. Please wait a moment.
Source drive size is 39 hours
- Upgraded to 342 hours.
Backup image will be 342 hours
Uncompressed backup size: 1175 megabytes

It all runs smoothly up until:
Backing up 1147 of 1175 megabytes (97.61%)

... and then freezes.


Any thoughts as to what is going wrong?

Thanks,
Mike.

Most likely drive corruption.

Try the MFSLive CD (http://www.mfslive.org) as that has more robust error handling. If you have the space on your FAT drive I would drop the compression too (use -so instead of -1so) as it is buggy.

Thanks Blindlemon for the suggestion though with mfslive I cannot mount my DOS drive with the syntax as described above; just comes back with:

Mounting /dev/hdd1 on /mnt/dos failed: Invalid argument

Perhaps I'm bootong in the wrong mode when the CD starts up. Which mode should I be using?

Thanks.

I normally use option 3. However, IIRC you have to create /mnt first - eg.

mkdir /mnt
mkdir /mnt/dos
mount /dev/hdd1 /mnt/dos
