Hi,Sorry to be so dumb but what is t43 ?
i do not know if the todays update has effected this, i think not.
While updating, the filesystem switched itself to only readable.
After that, i reboot my t43
and fsck.ext3 has to fix the fs.Usable ? Does it boot at all ? how far does it get ?
It recognize some errors, fix it, but the system is not usable.
...
When i use fdisk know, it shows a warning to me:This seems reasonably common, even when there is no problems that I can see with a machine. When using parted, the error message is:
Partition 1 does not end on cylinder boundary.
(parted) print
Warning: Unable to align partition properly. This probably means that another
partitioning tool generated an incorrect partition table, because it didn't have
the correct BIOS geometry. It is safe to ignore,but ignoring may cause
(fixable) problems with some boot loaders.
Another Problem:Bad blocks on the disk. Usually the drive is designed with reserve space, that is normally inaccessible. When a failing sector is detected, smart can remap the bad block to the reserve area (and lets you know about it). Sometimes this is indicative that the disk is beginning to fail - especially if more and more sectors show up as bad over time.
smartd shows me in the /var/log/messages sometimes:
Device /dev/sda, 1 Offline uncorrectable sectors.
Is this an error, is this a powermanagement feature from the hd, which
smartd does not recognize?

So before i reinstall the system, i have some questions here:# fdisk -v {fc6 dvd disc and updates to 2006-12-14}:
Is the fdisk on the fedora core 6 DVD an old one?
fdisk (util-linux 2.13-pre6)
dvd/Fedora/RPMS/util-linux-2.13-0.44.fc6.i386.rpm
machine updated to 2006-12-14:util-linux-2.13-0.45.1.fc6
# rpm -q --info util-linux|grep Date
Release : 0.45.1.fc6 Build Date: Wed 22 Nov 2006 11:06:35 AM EST
Install Date: Thu 23 Nov 2006 07:34:31 AM EST Build Host: ls20-bc1-14.build.redhat.com
which partitionerback it up to some sort of removable media using:
should i use? How can i fix the partition table know?
dd if=/dev/hda of=/root/mbr-backup bs=512 count=1
then you could use a rescue disk to reapply the backup attempts to fix are not successful.
Can i ignore the smartd messages or is the HD defect?I would be making a complete copy of the disk to another drive, in case there is information that you want, just in case the disk goes dead.
Please, only answer when you know an answer, not only when you guessWithout more info from you I suspect you would be getting less than optimal advice!
it ;-)
