Disk A faulty, new copy doesn't work

Hi, I have a UK two disk Tivo, upgraded about a year ago to two 120Gb Maxtor drives, worked like a treat for ages. Now Disk A has started clicking and PowerMax finds a fault.

I copied the faulty Disk A to a new 120Gb Seagate drive (slightly smaller in terms of bytes though) using the dd command from Hinsdale:

dd conv=noerror,sync if=/dev/hda of=/dev/hdd bs=1024k

Copy went fine, input and output totals were the same although several disk errors were reported towards the end.

I put the new disk A into my Tivo and it hangs on the "Welcomel, Powering up..." screen. Putting the original Disk A back in works fine (until the next disk crash..).

Why didn't my new disk A copy work? Any ideas? Was it because the size was slightly smaller than the original 120Gb disk? Did I need to do an mfsadd command? Did the new disk need formatting for Tivo in any special way?

Any help appreciated.

Thanks
Russell

The size was likely the problem, but it also may have been that the 'dd' didn't get the right data from the original A drive since it's obviously partially corrupt.

Can you make a backup and then re-image the drives? Do you have an older backup?

Thanks for your reply weaknees.

I don't know what you mean by this? Can you expand a little.

> Do you have an older backup?

Yes, if all fails I can revert to the two original disks and do the full upgrade from scratch but I was hoping to extract as much as possible from the faulty disk A in terms of recordings and SPs.

Thanks

The size difference is a killer. You should be able to make a fresh compressed backup from the drive set, even if your A drive is a little dodgy. If you restore that to new A + old B you'll at least save your SP's. There's even a chance some of your recordings might survive.
