Hello,
I was wondering if the messages displayed during startup are recorded
somewhere that can be consulted later. /var/log/dmesg and
/var/log/syslog do not actually contain **exactly** the same messages
displayed during startup. They contain something related but
different.
Kind of a newbie question...
Reason I'm asking is that I just rebooted my amd64 sid box after a
week of no interaction (was out of town came back and machine was
inexplicably slow) and I got a whole bunch of nasty messages. Here is
what I could see on the screen at the end of the boot sequence:
Buffer I/O underrun on device sda5, logical block 68243
ata1: status=0x51 {DriveReady SeekComplete Error}
ata1: error=0x40 {UncorrectableError}
SCSI error : <0 0 0 0> return code = 0x8000002
sda: Current: sense key: Medium Error
Additional sense: Unrecovered read error - auto reallocate failed
end_request: I/O error, dev sda, sector 20181687
ata1: status=0x51 { DriveReady SeekComplete Error}
ata1: error=0x40 { UncorrectableError }
SCSI error : <0 0 0 0> return code = 0x8000002

So I boot off my knoppix CD and I try to mount the various partitions.
All of them mount except the home partition, the sda9. It's the one
where I had all my data.
Here is what knoppix's dmesg | tail says after trying to mount it
ata1: status=0x51 { DriveReady SeekComplete Error }
ata1: error=0x40 { UncorrectableError }
<these same two lines above repeated four times>
SCSI error : <0 0 0 0> return code = 0x8000002
sda: Current: sense key=0x3
ASC=0x11 ASCQ=0x4
end_request: I/O error, dev sda, sector 39652779
JBD: IO error reading journal superblock
EXT3-fs: error loading journal.
So it's not lookin so good... I mean it's lookin real bad.
Does anybody know a way I could still try to recover my data on the
sda9 partition (formerly known as /home) ?
Thank you for any help or suggestions.
Alex.
