Oh boy.. did I mess up?
(Click here to view the original thread with full colors/images)

Posted by: gormly

Hi all.

I just restored a backup to a new 30 gig maxtor and tried to start up my tivo with that drive. IT will not do anything.. just sits there at the "please wait" screen.

I hear no noise from the drive other than startup spin.

I have tried every jumper configuration (just in case) and still nothing.

I am thinking there is something wrong with the restored disk.

Is there a way to verify the contents of this newly restored backup?
I try to mount the new restore tivo disk in my PC and I get filesystem errors.

(I know it is not a VFat file system)

1.) What command can I use to mount and check out the contents of the drive(to see if restore worked)? what file system?

Details on the situation:
I backed up my original 30 hard drive to a 27 gig hard drive.
I did it in chunks via the split command.

I restored onto a 30 gig maxtor.
>> This drive had Fat32 before I started the restore.<<

The big problem is I can not remember the exact commands I used to do the backup, I am not 100% sure I used gzip, but I know I spit the files into 650megs each. I have tivodisk_aa through tivodisk_bb on my backup drive. (also, the total size of the backup is around 22gigs)

I used "cat /mnt/tivodisk.gz | gzip -d -c | dd of=/dev/hdc bs=1024k''
as the command to restore and didnt get any errors.

2.) Could it be that I am using gzip to restore but didnt use it to backup?
3.) Wouldnt I get an error if so?
4.)Also if I did not use gzip but just spilt the files, what command would I use to restore?

Anyway, please be kind on me, I know I prolly shouldnt be foolin around with the system since I an a linux newbie.

Thanks for everyones help, you have all been very kind.

Did you set the runideturbo flag to false as noted in the FAQ?

You can't use a non quantum A drive without it.

The Faq States:

3. Type the following followed by the enter key. ``mount /dev/hdX4 /mnt'' where the X is the either b c or d depending on if you connected the non Quantum A drive to your PC's primary slave, secondary master or secondary slave respectively.

This is the start of runideturbo setting change.
I have tried to 'mount' with no success.

I get this error:
/dev/hdc4: Success
FAT Bread Failed
FAT Bread Failed
mount: you must specify the filesystem type

That is where I get stuck.

Thanks for the help and the tip about runideturbo.
I should have spotted it since I read the Faq many times.

Looks like your backup/restore didn't work. The mount is failing because it can't determine the file system type.

It is hard to determine the actual issue since you don't remember what you did for the backup.

You can connect the drive (the maxtor you want to use as your A drive) to your PC and run a program like Winhex and show us the first sector of data. That will give us an idea what type of partition it is, or if its byte swapped.

I believe I used the dd command without the gzip and used chunks of 650mb?

I have tried this
cat /mnt/tivodisk_* | dd of=/dev/hdc bs=1024k
(its running so far)

I am going to bed now...
hopefully it works.

Do you think it will ;<

Thanks for the help

I will post the results.

gormly,

I was just trying to edit my rc.sysinit last night for the first time when I came across this exact same issue.

/dev/hdc4: Success
FAT Bread Failed

It looks like you have the TIVO hard drive connected to your computer as Master and it needs to be slave. This is the default for the drive, so move that jumper over two spaces and try again. Don't ask me why this is, but it works.

Good Luck!

indeed, if he had it on the primary IDE port as the 'master', thats the only drive Dylans boot disk doesnt byte swap, so he has perfectly good data on the disk...if the tivo had a fine Intel Processor in it...setting it to secondary master or primary/secondary slave, then restoring, then putting it in the tivo with the setting for master may resolve.

There is no spoon.

I did the disk backup (Quantum to 15G Maxtor) using Dylan's disk and dd.

It ran for a few hours, reported an entirely plausible number of records copied.

I tried to mount /dev/hdd4, and repeatedly got the "FAT bread..." error.

Removed the quantum, rejumpered the Maxtor to be master, rebooted the PC.

I tried to mount /dev/hdc4 - no problems

What gives? I dunno.

Ok now I am getting really frustrated..

I can not seem to get a disk recognized now or at least not a recognizable file system. (bios, yes all is ok)

On bootup, during the Liloboot process I do get the drives listed as hdb,hdc,hdd whatever they happen to be on they are correctly size listed.

But I get this statement as it lists the drives:

Block 0 has signature c033 rather than 1492
(I assume this is part of my problem)

Then I can not mount anything I just keep getting the messages I listed above.

1. It is NOT a jumper issue, or a primary/master/slave issue
I have tried every combination.

2. I can mount a good Tivo disk without problems.

There are two drives I am attempting to mount
one is Fdisked in (win98 boot disk) Dos and (win98 boot disk) Formatted in Dos - This is the drive I want to restore TO to put in a Tivo as the A drive.

The other is a fat32 drive I previously used to store my backup of the original Tivo
I used to be able to mount this drive before, because I could get a listing of the tivo backup chunks
(tivodisk_aa through tivodisk_bb)

I can see all the tivo chunks if I use a dos boot disk, so I now that drive is not corrupted.

I am driving myself crazy, I must be missing something simple.

What should I do?

Is it something in the partition table?
Could I have screwed it up somewhere?

-Someone save me please.

Damn,

I was sure that this was the same issue that I had last night. I don't have any other answeres for you, but I do know that I had those same disconcerting errors last night.

quote:

Block 0 has signature c033 rather than 1492

I am not sure if it was when I had the drive on as Master, or when everything was working fine on Slave. I do know that dispite this error, eventually everything was working fine.

All I can suggest from my feeble Linux tech skills is to make sure that when you have the drive set as slave, that another drive on that cable is not set to slave also.

Good Luck,

Gultig

Posted by: gormly

Yep

I can't figure it out.

I didnt seem to get all these errors before, but now I do.
I have tried every setting and cable combination.

Thanks for the effort.

Any other guru out there have a suggestion?
How about the Great Otto?

Well C033 for block 0 means it is a DOS disk.

The only advice I can give you is only hook up your original TiVo drive to the primary slave, or either secondary ports.

Never connect your DOS drives to anything but Primary master.

If your DOS drive has multiple partitions on it you may need to use different device names for the mount. I.E. /dev/hdaX. Try values for X from 1 on up.

You are probably going to need to redo the backup.

Did you try remounting before a reboot after the backup?

Linux probably didn't see the partitions when restoring a backup to a new drive. (When you run pdisk it forces the OS to see the changes).

So the powering down and back up is probably what allowed you to mount the drive the next time.

Hey, when I first booted, it said that the signature on the Quantum was 0000 rather than 1492 (or whatever).

I just plunged ahead, anyway. Somehow, the copy seemed to have the right signature, which made the whole process suspect.

I wish people would stop saying this. The fact that the drive is byte swapped has nothing to do with the processor. PPC Macintosh drives and LinuxPPC drives are not byte swapped. We use the same byte ordering on our drives as you do. The TiVo is doing its own thing.
