mfsrestore stuck?

I'm trying to restore my original Tivo A drive (40gig) from the backup I took when I started the upgrade. See, my harddrive failed the Powermax miserably. So, I'm sending it back and wanted to restore my Tivo A drive (since my new drive was the B drive, and original was A).

I set it up, put in the command:

mfsrestore -zpi /mnt/dos/tivo.bak /dev/hdb

Now, that's definitely where the TivoA drive is (hdb) and it starts off okay:

Starting restore
Uncompressed backup size: 1365 megabytes
Restoring 20 of 1365 megabytes (1.53%) (95.22% compression)

Then it sits there. The compression will change. 525.34% 943.95% and then back down to 243.45% or something. It seems random. The other per cent never changes. Never past 20 megabytes. I've waited an hour. (I've also tried the mfstool restore option - same thing.)

When I first did the upgrade, I tested the backup on my new hard drive and it worked perfectly. Restored in no time. I tested it my Tivo and it worked. Any idea was a restore would fail now? Do you have to do something to the original before you start a restore to it?

Thanks all.

Uggg.

I can't even restore to another hard drive. I get nothing back from the restore command at all. It just hangs there. So, it appears I have a good backup (since it worked once), but I can't restore it to any hard drives. Why would it hang??? Is there any log created that I can look at? See what this guy is up to?

Try using a hard disk utility to check for bad blocks/sectors/etc. - you seem to have figured out that your backup is ok...so now eliminate that possibility that your hard drive is having problems and/or hosed.

Go to the manufacturer of the HDs site and there are usually DOS (or other type) of utilities you can run to check the health of your HD(s).

For those keeping score at home... and if anyone has this happen to them. I think the problem is the disk where my tivo.bak is stored. I had an old 10Meg hard drive (since I have Win2000), so I formatted it as Fat and used it as my primary c drive when I initially did my upgrade. Everything worked (and I also backed up my tivo.bak to another hard drive since then).

No, I think that drive is bad. I can't even see it anymore. I realized there's all these read errors too. That's two bad drives in one week. Jeesh.

So, scrap that drive for now... I'm using my main drive, using Partition Magic to get a new partition on it. Then, I'll copy the tivo.bak there and try this whole thing again.

Thanks for all the help - this board is great!

ARRRrrgggg...

What the odds? My backup, that I tested, that worked, which I even copied to another drive somehow got corrupted between the test and the copy. So... I've lost my only backup. Actually, it's there, but when I restore it gives me the error:

Restore failed: Premature end of backup data

So... it looks like the backup is bad. I'm pulling some bad newbie problems here... but... anyone know where I can get an image for a Philips DirctTivo unit? 40 Gig single drive? Anyone? Be so greatful...

Thanks all.

anyone know where I can get an image

If anyone did know, there's no way they could tell you because you've got PM's turned off!

Thanks Robert!

Thanks a million Robert. It looks like I'm back in the show...

Lessons to be learned (I think I remember you posting this somewhere else, but it should be in caps at the top of the Hinsdale) is to shelf your original drive! That would save so many problems...
