Restoring a TIVO drive
(Click here to view the original thread with full colors/images)

Posted by: Mike2001

I am attempting to restore a TIVO drive from an image. The image was taken from a winrar filed and when extracted creates a file called HDR112.3.0.mfs and copied to a CD rom

I have my drives setup as so:

hda: c drive
hdb: none
hdc: TIVO drive
hdd: CD rom

When I attempt the restore command:

mfsrestore -zpi /mnt/dos/tivo.bak /dev/hdc

I get an error message file tivo.bak cant be found.

What am I doing wrong? What should be the correct command to restore the TIVO drive

in that image anywhere is there a file called tivo.bak? if not then thats why you could try replacing tivo.bak with whatever the filename is, also make sure its in your C:\ directory what series tivo?

Its a series 1 Philips HDR112. I have tried to replace tivo.bak with HDR112.3.0.mfs and many different combos of replacement names all come up with the error. Is the format incorrect and unreadable?

Typically, the backup image file is named Tivo.bak. In your case, it appears to be called HDR112.3.0.mfs, so replace "Tivo.bak" with the "HDR112.3.0.mfs" in the command.

Are you sure that the .mfs file is an image file?

Also, it sounds like you copied the file to CDROM and are trying to restore it from there as opposed to from the c drive. If this is the case, did you correctly configure your command line entry? In other words, /mnt/dos is not pointing to the CDROM drive.

One other thing to consider is what version of MFS Tools was used to make the image and what version are you using now. If they are both v2, then no issues, however if image was created with v1.0 then you have to add "b" modifier to the command line entry.

Did you mount the drive first after you booted from your mfstools cd?

#mkdir /mnt/dos

#mount /dev/hda1 /mnt/dos

#mfsrestore -zpi /mnt/dos/HDR112.3.0.mfs /dev/hdc

After restore is done

#umount -f -a -r

then do a clrl alt del to reboot

Don't second guess the name of the file. Find out for sure what the file name is. If you need to rename it to tivo.bak that is fine.

Good luck and hope that helps.

if the file is on the cdrom you need to mount it the cdrom not /dev/hda

the commands to do this would be(specific to your setup)

mkdir /mnt/dos

mount -t iso9660 /dev/hdd /mnt/dos
"it should say something about mounting read-only"

mfsrestore -zpi /mnt/dos/HDR112.3.0.mfs /dev/hdc

"if expanding"
mfsadd -x /dev/hdc

umount -f -a -r

ctrl alt delete

your image should work now.

The first post says he is using "C" on first controller which probably means he has the image on that drive.

I would also test the image out before expanding the drive.

Just my .02.

Ignore what tac25 and Piggers said about the -b option. That forces Big Endian mode - required for Series 2 TiVoes. Your HDR112 is a Series 1 TiVo and requires Little Endian mode, which is the default.

I'm not sure why you're trying to restore the backup from a CD when you still have your C: drive attached. Copy/rename/whatever the backup file so that it's called C:\TIVO.BAK

If the Hinsdale commands don't work once you've done that, hda1 is not your C: drive, so try mounting hda2 or hda5 instead.

OK, renaming the file tivo.bak did the trick. I sucessfully restored the drive and now have a main drive to work with. Thanks to Piggers and joker81. Thanks guys. I owe you a bunch
