copy hda4 partition??

I have two 112's one has an 80 gig HD and the other has a 60 gig HD, both maxtors and both with turbonet cards. The 60 gig tivo is starting to have drive problems and somehow the software on it has been corrupted so that it no longer sets up the network. I can't even ping it.

I've swaped the drives around and it is definitely a software problem. I have ordered a replacement drive and it will be a few days before it gets here. What I'm wondering is this. Can I copy the hda4 partition from the 80 gig to the 60 gig drive? I'd like to still get the guide data while I wait for the replacement and IIRC the season pass and thumbs up/down info is in MFS. If I mount both drives in a PC and boot from one of the tivo boot disks what command would I use to copy hda4 over?

I'm thinking it would be something like
dd if=/dev/hdd4 of=/dev/hdc4 bs=1024k

where the 80 is the slave on the second ide channel and the 60 is the master on the second ide channel.

Am I making a mistake here?

Is there a better way?

Thanks,
Cat

Looks good to me.

If you wanted to make a backup file from that partition you could do

mount /dev/hda1 /mnt
dd if=/dev/hdd of=/mnt/root1.raw
umount /mnt

It's 128Mb, so it should cause a space problem on your c: drive. Might be sensible to backup the dodgy partition before you overwrite it so you can go back if necessary.

Wouldn't that make a copy of the entire 60 gig drive onto root1.raw?

Sorry, yes, my mistake. The partition would be hdd4, not hdd.

It didn't work. I tried booting from the CD and chose each boot option and never could get it to work. Sometimes I'd get zero records read 0 records written and I never was able to boot up with swap nor dmaswap

Which boot disk are you using?

I tried the MFSTOOLS boot CD and boot floppy.

I assume you mean MFS Tools 2.0? Byteswapping is broken on those disks. Try the net install CD (nuboot6.iso) or Dylan's Boot Disk. You can make MFS Tools 2.0 byteswap. See the first post in the Fixes thread.

If you see the TiVo partition table printed at boot then it should work.
