mfs_load_volume_header: mfsvol_read_data: Invalid argument

[sberger]

I have a Series 2 (240080) that I upgraded a few years ago from an 80GB to a 160GB. My 160GB seems to be failing, and so I am trying to move to a 500GB Western Digital.

Using MFS Tools 2.0 and the same command as in years past...

mfsbackup -Tao - /dev/hdb | mfsrestore -s 127 -r 4 -xzpi - /dev/hda

I get
mfs_load_volume_header: mfsvol_read_data: Invalid argument
mfsbackup: Backup failed to startup. Make sure you specified the right devices and that the drives are not locked.

When I <shift><page up> I see that my drives are seen on hdb and hda, and that the size of my new drive is recognized (500GB), but the OLD TiVo drive shows a size of 33GB!! In fact, it shows

hdb (TIVO_DRIVER_MAGIC) hdb1 hdb2 hdb3 hdb4 hdb5 hdb6 hdb7 hdb8 hdb9 hdb10 hdb11 hdb12 hdb13 hdb14 hdb15 hdb16

I also note the error:
kmod: failed to exec /sbin/modprobe...

(Also, new 500GB disk is not locked. Checked with diskutil.)

Any suggestions??? My TiVo OS is 9.1.

Did you happen to put the jumper on the 32GB limit pins instead of slave?

What the output of mfsinfo /dev/hdb

Future problem: Unless I missed it and the expand once has been fixed. You can not easily re-expand and keep recordings.

HomeUser,

Thanks so much! You're were right. I put the jumper on 32 GB. I can't believe I did that.

I'm all set now (but here's the rest of the story for completeness)...

mfsinfo /dev/hdb has the output

The MFS volume set contains 6 partitions
/dev/hdb10
MFS Partition Size: 256 MiB
/dev/hdb11
MFS Partition Size: 34207 MiB
/dev/hdb12
MFS Partition Size: 256 MiB
/dev/hdb13
MFS Partition Size: 42991 MiB
/dev/hdb14
MFS Partition Size: 0 MiB
/dev/hdb15
MFS Partition Size: 74384 MiB
Total MFS volume size: 152095 MiB
Estimated hours in a standalone TiVo: 175
This MFS volume may be expanded 3 more times.

I tried again the command again

mfsbackup -Tao - /dev/hdb | mfsrestore -s 127 -r 4 -xzpi - /dev/hda

and got the result

Scanning source drive. Please wait a moment.
Source drive is 81 hours
- Upgraded to 175 hours
Uncompressed backup size: 151032 megabytes

After waiting a few minutes and not seeing anything, I hit Enter on the keyboard and saw the line

Restore failed: Backup target not large enough for entire backup by itself

So I guessed I was up against the problem you mention and tried the line

mfsbackup -f 9999 -so - /dev/hdb | mfsrestore -s 127 -r 4 -xzpi - /dev/hda

I now have a working TiVO with 628 hours! Yay! Of course, no recordings.

I guess I'll go ahead and upgrade my other TiVo now and then transfer my old programs over to that one.

Thanks again for your help!
