I am very new to this. I bought 2 identical hughes dvr-80's recently. I attempted to hack one of them, and messed it up completely. The second is totally virgin--never even turned on. I figured that if I hosed the first one, I could use the second to fix the first.
I put both drives into my PC, booted from the CD-ROm and did a dd if=/dev/hda of=/dev/hdb to duplicate the contents of the "good" disk onto the "hosed" disk.
When i put the hosed disk back into the tivo, it just stays "stuck" at the "welcome...powering up" screen. The virgin disk works just fine.
I'm puzzled....am I missing something here? I thought that the dd command would duplicate everything (even the blank space).

Don't use hda. Move the drive to another position in the ide chain.

Be sure you put the HD jumpers back the way they belong when you put it back in the TiVo.

Why should you not use hda?

Some boot cd's/disks byteswap hda. Since I am not exactly sure what CD is being booted (nor do I remember which cd's use byteswapping) I generally stay away from hda to be safe.

Whenever performing a backup or restore using MFS Tools 2.0 it is a general rule of thumb to avoid installing a Tivo drive as primary master due to the potential byteswapping issue as indicated in the other posts. Normally you would install the original drive as secondary master and the new drive as primary slave. Check out Hinsdale's How To for the syntax and configuration required for this process. You should also include the block size for the dd copy at the end of the command line. Here's the line from Hinsdale's:
dd if=/dev/hdc of=/dev/hdb bs=1024k

WOW, i missed this important info.
I used HDA for all 3 of my HDVR2's so I would be sure I didnt have the XP drive connected to keep the other important piece of information an impossibility. ("dont let XP boot with your tivo drive connected".)
I have an HDC formatted FAT 32 with the images and such, HDD is cdrom.
I guess I got lucky! whew~~~!
Or I wasnt lucky, just wont be a problem since I booted off of HDD-Cdrom????
