View Full Version : Anyone know a command line to make a duplicate of my Tivo HDD?

I have a 250gb Samsung 5400RPM in one of my Tivos and I'd like to "clone" that HDD, kernel update, recordings & all, for my other Tivo.

Using an MFSTools boot CD is there a command line I can use to make an exact copy of that HDD onto another 250gb Samsung 5400RPM HDD?

I am able to have both HDDs connected at the same time, typically I'd have the original disk on hdb and the destination disk on hdc for a normal disk upgrade.

Thanks,

Mark.

Do you want an exact copy - ie. sector by sector? In that case use DD:-

dd if=/dev/hdX of=/dev/hdY bs=2M conv=noerror,sync

Or do you just want a copy of the TiVo OS and recordings excluding the empty space? In that case:-

mfsbackup -Tao - /dev/hdX | mfsrestore -s 300 -r4 -xzpi - /dev/hdY

followed by copykern to initialise the swap.

Make sure you use the LBA48 Boot CD (ptv-mfstools2-large-disk.iso) in both cases or you will only copy stuff up to 137gb :eek:

Is one method better than the other? Either will do what I want to achieve.

I want to put all the changes I've made to the OS and also the shows on my other Tivo.

Both methods will copy everything, although the 2nd method requires you to run copykern afterwards.

If your drive is 100% full then both will take a similar amount of time; if your drive is not full though, the 2nd method will be quicker, maybe a lot quicker if your drive is only half full or nearly empty and especially so if you run my PurgeDeleted script via telnet first ;)
