2 drive upgrade.
(Click here to view the original thread with full colors/images)

Posted by: ironman

Hi,
I am new to tivo having used one for only a few weeks, I must say I have been very impressed by the level of support recieved from all the members of the board! I have bought a Samsung 120gb drive to add to my tivo which is a 2 drive model. One of the drives is 30gb and the other is 15gb, am I correct in thinking that it is the smaller of the two drives that is to be substituted? Or is it the one with the operating system on?
I am not doing the job my self a friend who is a computer wiz kid is tasked with this one. I had a computer crash at the weekend and had to format my c drive and lost a bit of data concerning the upgrade. Before that I burned the MFS TOOL2NDJ.IOS file onto CD. Is this all I will need to substitute the drive for a 120 upgrade?
Thanks for any help offered.

Normally it would be the larger drive you'd use.

Typically you would make a backup of the two disks together, then restore the backup to the 120Gb drive on its own, and finally add the 30Gb as a second drive. This is all explained in the Hinsdale guide.

Doing that would lose all your recordings (but not Season Passes).

It is possible to do it while keeping all your recordings, but its not recommended as your expanded Tivo won't then be able to recover properly from any serious software errors it encounters in the future.

Hi,

Out of interest why wont it be able to recover from software errors in the future if he backed it up with the recordings?

Thanks

Probably, because it wouldn't increase the size of the swapfile. The current swapfile will not be large enough to recover from the Green-Screen-Of-Death (GSOD) once the drive sizes have been increased. There is way round the problem (it keeps rebooting back to the GSOD), buts it's a bit messy.

Hi,

ah, ok. But if you do a normal backup without the recordings, it does increase the swapfile?

Thanks

To increase the size of the swapfile, you need to use '-s 127 ' with mfsrestore. If you use 'dd' to copy your recordings you wouldn't have that option. However, I don't know why using the 'mfsbackup | mfsrestore' pipe method wouldn't work and increase the size of the swap file.
