how do I get my image off the cd

Posted by: severeamoeba

Okay.. my backup image is on a cd_rom. Question is.. how do I get it off. Can I dump straight from the cd .. to the drive or do I have to put the image onto a harddrive? Either way.. could someone clarify the linux commands needed.. I dont know anything about linux, and I cant seem to see the mount commands I need... so if someone can help.. please assume your dealing with a complete novice when it comes to the commands and such. Thanks for your help.. whoever you may be.

How did you create the image?

Did you use something like:

dd if=/dev/hdb | gzip -c9 > /tmp/TivoBackup.dd.gz

If so, then you can use:

gunzip -cd /cdrom/TivoBackup.dd.gz | dd of=/dev/hdb

Note: I see people cat'ing their gz's into gunzip/gzip -d commands, this is not necessary, the above command works just fine.

Well it's pretty straight forward....

If you have been lucky and the backup is in one CD-ROM then the instructions of the last post are OK

If the backup is in several CD's then the way to do it is the following:

Copy all the archives from the different CD's tivodisk_a* to a fat formatted drive

Drive to restore to connected to secondary port as the master drive ( /dev/hdc ), fat formatted drive with the tivodisk_a* files connected to Primary port as the master drive ( /dev/hda )

Boot with dilan's disk http://www.tivofaq.com/hack/tivoboot_v3.zip

Log as root

Type mount -t vfat /dev/hda1 /mnt'' (no quotes)

that makes accessible the disk with the files of the backup to the operating system (linux), and mounts it in the directory /mnt...
if you type "cd mnt" and then type "ls" (dir in ms-dos) you will see the files of the original backup drive (no quotes)

Type cat /mnt/tivodisk* | gzip -dc | dd of=/dev/hdc obs=1024k'' (no quotes)

That in essence "types" all the contents of the decompressed files of the backup (tivodisk_*) and raw writes in the drive hdc (c stands for secundary master)

Then you are set.

All this is explained in

While it needs a little bit of thinking http://www.avsforum.com/ubbtivo/smile.gif))

Hope this helps

By the way... this is for all, now it's payback time http://www.avsforum.com/ubbtivo/smile.gif), over the last month or so I've been asking questions regarding how to use and setup a TiVo overseas and using it in a PAL country, I've succeeded in doing so, if any one wants to do it pls do not hesitate to contact me (mainly trough the forum so everybody is aware) if you are in trouble.

Now This one for Otto:

Regarding the Nag Screen. In the setup I've described the nag screen is a pain in the ass, so I've found ways around it, but they are not very "elegant", I'm searching in that direction.

- Is that particular topic (nag screen) allowed in the forum ?

Bye
