First of all: Thanks for your very fast
and helpful response.
I copied actually only the partition, not the whole disk: dd_rescue --force -r1 /dev/sdd1 /dev/sdc1 The cause for this is that I don't have enough space left on another device to store a whole copy of the faulty disk. I thought it would be possible, like in some examples I found with google, that you can rescue a partition directly. file -s /dev/sdc1 says: /dev/sdc1: data The disks look like this (fdisk -l): Disk /dev/sdc: 3000.6 GB, 3000592982016 bytes, 5860533168 sectors Units = Sektoren of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0xcba506ee Gerät boot. Anfang Ende Blöcke Id System /dev/sdc1 256 732566645 366283195 83 Linux Disk /dev/sdd: 2000.4 GB, 2000397852160 bytes, 3907027055 sectors Units = Sektoren of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x3c34826b Gerät boot. Anfang Ende Blöcke Id System /dev/sdd1 63 3907024064 1953512001 83 Linux If it is not possible to rescue the partition this way I will have to extend my to RAID5 so that I can put the copy of the faulty disk on this one, like Michael explained in his answer. I just hoped that I can avoid this, because it would save me more than 100€. As last information: The content of this copy is not totally lost, actually only the last few files I have added. All the other stuff is already stored on the RAID5, only the latest stuff is not contained in this backup. So I don't loose everything if something goes wrong (at least one thing :-) ). Kind regards, Benedikt |
