I'm trying to go through https://raid.wiki.kernel.org/index.php/Recovering_a_failed_software_RAID echo $DEVICES /dev/sda1 /dev/sdb1 /dev/sdc1 /dev/sdd1 parallel -j0 dd if={} of=/dev/null bs=1M ::: $DEVICES dd: error reading '/dev/sdd1': Input/output error 23510+1 records in 23510+1 records out 24652464128 bytes (25 GB, 23 GiB) copied, 173.685 s, 142 MB/s Or is that just doing a scan and just checking which drive are bad? I sure would like to get that 25GB back. Is that possible? I also see this: ddrescue -r 3 /dev/old /dev/new my_log ddrescue -R -r 3 /dev/old /dev/new my_log Can I just use a mount point for /dev/new?
