Hi all,

I am upgrading my HR10-250 from 2 250gb drives to 2 500gb drives and I want to keep all my recordings. Presumably using MFSLive is the way to go, but my question is this:

Since I only have 2 IDE ports (4 drive max) on my PC, and I need one of them for the CDROM to do the upgrade, what is the best way to go about this? Should I first merge the dual drives into one using:

backup -qf 9999 -so - /dev/hda /dev/hdc | restore -s 128 -r 4 -xzpi - /dev/hdd

and then add the second 500gb drive (after reconnecting things in the PC) using:

mfsadd -x -r 4 /dev/hdc /dev/hdd


Any suggestions would be greatly appreciated...

If you can, boot MFSLive from a USB or USB Thumb drive.

Most people I talked to used pci ide card, or usb to ide adapter.

I've never tried but supposedly you can merge original A & B drive to one.
Then add new B drive. (This method only works if you A drive is the original capacity)

So do (without x and -r 4)

backup -qf 9999 -so - /dev/hda /dev/hdc | restore -s 128 -zpi - /dev/hdd

then

mfsadd -x -r 4 /dev/hdc /dev/hdd

Let us know how it turns out.

Well, unfortunately the command aborted 60% of the way through. I ran diagnostics and one of the old 250gb drives failed. I would still like to try to salvage the recordings so I'd like to try the dd_rescue/knoppix approach. Any idea the best way to approach this? Using the abbreivations as follows:

OldGood = Current 250gb drive that originally came with the HR10-250
OldBad = Current 250gb drive I added a couple years ago, that is now failing
New#1 = New 500gb drive to hold current original 250gb
New#2 = Other New 500gb drive to hold the 2nd 250gb

I was thinking maybe the following steps:

1) OldBad -> New#2 via dd_rescue
2) Put OldGood and New#2 back in Tivo to see if it is working as before
3) If so, then do mfsadd on the New#2 to bring its space up to the full 500gb
4) OldGood -> New #1 via a backup/restore
5) Do mfsadd on New#1 to bring up to full capacity

If you think this is a reasonable approach, any ideas on the syntax for the commands?

Thanks again for all help!

I do not think that step 4) "OldGood -> New #1 via a backup/restore" will work, you would need both 'A' and 'B' drives installed and use MSFLive 2 drives to 1 option however there may be a space problem depending on the actual size of the drives.

Otherwise you could just dd copy the old-good to New #1 then expand again with mfsadd.
