Salvaging data from a RAID-5 where two disks failed

[Danie Roux <droux@tuks.co.za>]

Hi All,

I have 4 drives in a RAID-5 configuration.

One of the drives broke. I replaced said drive, did a 
'raidhotadd /dev/md0 /dev/hdb2'. Watched it for a while and then went
home. 

And then /dev/hde failed too. The syncing wasn't done:

Jan 25 19:17:23 clio kernel: hde: dma_intr: status=0x51 { DriveReady SeekComplete Error }
Jan 25 19:17:23 clio kernel: hde: dma_intr: error=0x40 { UncorrectableError }, LBAsect=80464841, sector=79214920
Jan 25 19:17:23 clio kernel: end_request: I/O error, dev 21:03 (hde), sector 79214920
Jan 25 19:17:23 clio kernel: raid5: Disk failure on ide/host2/bus0/target0/lun0/part3, disabling device. Operation continuing on 2 devices
Jan 25 19:17:23 clio kernel: md: updating md1 RAID superblock on device
Jan 25 19:17:23 clio kernel: md: (skipping faulty ide/host2/bus0/target0/lun0/part3 )
Jan 25 19:17:23 clio kernel: md: md_do_sync() got signal ... exiting

And then ext3 went bonkers:

Jan 25 19:29:11 clio kernel: EXT3-fs error (device md(9,1)): ext3_get_inode_loc: unable to read inode block - inode=32997377, block=65994779
Jan 25 19:29:12 clio kernel: EXT3-fs error (device md(9,1)): ext3_readdir: directory #17055779 contains a hole at offset 0
Jan 25 19:32:56 clio kernel: EXT3-fs error (device md(9,1)): ext3_get_inode_loc: unable to read inode block - inode=26214401, block=52428827

Ok, so my question is: 

Any way in which I can salvage at least a part of the data?
