fsck bad or duplicate block(s)

at boot disk gets scanned, bad or duplicate block(s) are reported.
it says i have to run fsck manually.

what fsck arguments should i use ?
i used "fsck /dev/sda1" "fsck -f /dev/sda1" "fsck -c /dev/sda1" but it just displayed some short data, filesystem modified and exited.
after reboot it scans again, with same errors :(

i tried tried removing problematic files manually, umount /dev/sda1 .... mount -o rw,remount /dev/sda1 , but it displays "read only filesystem".

ozo

sudo fsck -p

ozo

or set the fsckorder field in fstab to 0 to prevent fsck from scanning

it said "RUN fsck MANUALLY ( without -a or -p options) "

ozo

> fsck -p
the options may be different on your fsck, check your man pages

is "fsck -p" different than fsck run automatically at boot ?
i am running "fsck -p" currently, this is already my 5-th fsck today, and each one takes ~ 30 minutes.

If it says not to use -p or -a, then don't use them. Just fsck /dev/sda1. In your Q, you say you tried that and errors persist - can you post the fsck output? (you might have to write it down - do what you can)

fsck on /dev/sda1 didn't work because it's a LVM disk.
but i'll give half points each.

anyway i just bought new disk.
