dcheck doesn't detect bad blocks under RTP

Hi
I has old HDD with some amount of bad sectors. After creation qnx4 partition
on it dcheck (RTP PatchA version) said that
all is OK. I wrote some files on that partition, but when I tryed to read
them (via cp to null for example) system hangs!
Then I use dcheck again and again get that all OK.
So how can one check hard drives under QNX 6?

BTW, when I rebooted into QNX 4 dcheck found bad blocks on that partition
and cp to null aborted with Input/Output error message (and system was
operational after that!)

Regards
Boris

Did you do the command-line option to enable bad sector testing? I think it
does not by default…

And what this utility can do but finding bad blocks? IMHO it can mark it or
not, but should find it in any way.
I used dcheck -m on both systems. On QNX4 it works on RTP it doesn’t find
bads though it checks
some blocks noticeably slower than others.
