If you can see the display of blocks processed and 244,140,625 (1000,000,000,000 / 4096) is the approximate total number of blocks, if you take the time taken so far divided by number of blocks processed times 244140625 you will have the estimated total time. Just subtract time taken so far and you have time to completion.
Now I'm wondering why I didn't think of that. D'oh! And thanks. :-)
If you saved the badblocks list to a file using the -o filename option you can input it to fsck.reiserfs, read man fsck.reiserfs for more info.
Yep, that's my intention.
If smart is disabled on the drives and data was static for a long time you may be able to recover the sectors by doing a few zero write passes but this will take a long time. Its a good idea to run a western digital disk utility on the drives. The biggest cause of bad sectors is data that is static for a long period of time. Regards Dave P
SMART doesn't seem to work over USB, but the data has been relatively static. When you say "zero write passes", is that an option to fsck or badblocks?
I'm pretty sure he is saying that if you are willing to accept that the data is lost, but you want to put the sectors back in service you can overwrite them with zeros. In deed that should work. The drive itself should have kept track of all the sectors that failed to read. When you write to those sectors, the drive itself should remap the logical sectors to good sectors from a spare supply that it has. ie. Every drive is made with spare sectors used for replacing failed sectors. The activity of performing the replacement only occurs on sector write. Also, the most recent versions of hdparm have new options related to working with sectors. I don't remember exactly what it can do. The version with 10.3 is not new enough. You need something from the last few months. (8.3 or newer I think?)
