Greetings all,
At what point do I abort DD?

I've used MFS Tools before to move my SAT-T60's 40GB contents to a WD 160GB drive. Quite a bit of time has passed since then, and the WD drive is starting to exhibit intermittent bearing whine. I have an identical 160GB drive purchased at the same time, so I hooked 'em both up to a PC (no other boot drive connected - only the CD-ROM for the MFS Tools CD) and did the DD command.

24 hours later, there's still no return to the Linux prompt. I can't tell if there is drive activity or not: the drives are too quiet, and they don't have activity lights.

Should I abort the DD process? If so, what alternative should I use to copy everything (including shows) from the Tivo 160GB to the other 160GB?

Thanks,
Chris

Press the Shift key Linux may of gone into sleep mode.
I would think that after 12 hrs it should be done unless you have a really slow system.

The DD command has finished, although I don't know whether it succeeded.

The screen displays:


/# dd if=/dev/hdc of=/dev/hdb bs=1024k

dd: writing '/dev/hdb': No space left on device

131071+1 records in
131071+0 records out
/# _


I haven't yet put the duplicated drive in the Tivo to see if it boots. Am going to do a little research to see about this "No space left on device" message.

That does not read good, are the drives really identical, the same brand and model?
You can check the drive size with the dmesg | grep -i ide if there is a minor difference you might have to use MFSTools backup/restore and adjusting the size of the swap partition to make room.

Also while you're in there see if Linux is using the hard drives in PIO mode or DMA.

I had to use a Knoppix disc to fix one of my Tivos (LBA48 mfstools bootdisks don't boot for me) and a mfsbackup was running for over 12 hours and was only 50% done. Turned DMA mode in Knoppix on and it finished the rest in less than an hour... *grumble*

This was only copying a 80GB drive with recordings.

It also speeds up the transfer if the source and destination drives are on different IDE channels.
