[b]Disk status: CRITICAL
CAUTION! Sectors that required more than 6 read attempts detected, drive may be ALREADY FAILING![/b]

doesn't look so good... what can i do about it? it's a laptop btw with a regular non-ssd hd

The only sector that needs closer examination is the 360'th block. I don't know why it didn't retest it more, 4 samples is very low for a sector with 23ms 3rd quartile.
Some disks can't read 0th and 1st sector the way I'd like them to, you can safely ignore 'em with the rest looking like this.

To confirm:
create file disk.bad with this content:

88064 96511

and run hdck as this:

hdck -r disk.bad -f /dev/sdX --min-reads 20 --max-reads 50

It will thoroughly test this part of the disk.
If the problem persists, you can try to "rejuvenate" those sectors by reading this part of the disk and writing it again using dd, it's highly recommended to do it from a LiveCD environment.

sorry for my miserable english, it's my third language ; )

"Disk status: excellent!"

Maybe I interfered with hdck while it was doing the tests before?

with only 4 samples it's very likely that it was constantly interrupted while trying to re-read this block.

Re: hdck - new software for testing hard drives - v.0.5.0

Hi guys. I have another project like this one. WHDD.
https://github.com/krieger-od/whdd

Gentoo users can install it from sys-apps/whdd in portage tree.

There're no packages for other distros yet. Package maintenance help is highly appreciated.
