Followed instructions from rosswalker.co.uk/tivo_upgrade/#linux
cat /proc/partitions (Showed correct drives and sizes)
Printed them off, copied command and put ^ where spaces were to be so I was exactly like copied off page when I input the command.
inputted:backup -qTao - /dev/sda | restore -s 128 -xzpi - /dev/sdb
hdparm -k 1 -B 1 -M 128 /dev/sdb
I popped it out again and checked partitions, the new drive has same partitions as the original as well as 1 more at the end with 1.85tb space showing for it as like sdb17
If you're using the MFS Live bootable cd, then
should show the partition maps for any TiVo drives attached to the PC.
That one big partition at the end should be labeled as a "Apple Free" partition, which is what the Apple Partition Map uses as a label for unpartitioned space (the Map itself is the first partition--when Apple says "think different", they ain't kiddin')
If you're running Windows XP or newer on that PC when you don't boot from a cd, then using WinMFS might well be the easiest and least likely to go wrong method from here on out.
(When you appended the
option to the restore command, it should have done the same thing as if you'd done the restore without it and then run
but since it didn't add a 3rd MFS Application/MFS Media partition pair, the expansion did not happen.
This is not uncommon, which is why I advise skipping the
option when doing
copies of other drives or when restoring from a .bak truncated backup file and checking the target drive with
mfsinfo /dev/sd[insert letter for target drive here--in your case it was 'b']
afterwards, and only then after seeing things look okay using
(where * depends on which is the target drive)
to do the expansion, if the target drive is bigger than the drive from which the image was originally taken.
A restoration without expansion should give you 2 MFS pairs, and the
option should have put one of the MFS Media partitions near the front of the drive (which is how it's supposed to be for Series 2 and Series 3 platform TiVos), and then
should add a 3rd MFS pair.
I haven't really experimented with the MFS Live cd version of MFS Tools and 2TB drives, because I found out WinMFS will do what I want without any extra fuss and bother (except for it being better to do the expansion as a later separate step with it as well), so I don't know for certain how MFS Live would handle a 2TB. It might limit that 3rd MFS Media partition to 1.2TB, I just don't know.
If you need WinMFS let me know.
