Recently a cvsup failed because of an input/output error in the
directory /usr/src/contrib/perl5/h2pl. I tried deleting the content of
the directory, and found out there were hardware problems with the
disk. For it says:

ls: eg: Input/output error

And in the console messages:

Feb  1 00:50:10 zeist /kernel: ad0s1h: hard error reading fsbn
99107103 of 27000944-27000959 (ad0s1 bn 99107103; cn 6169 tn 33 sn 39)
status=59 error=40

Similar messages appear for this physical address and another one when
the filesystem is checked daily at 03:00 h. This is happening for some
time now (since January 18), but did not give any problems.

Jan 30 03:05:54 zeist /kernel: ad0s1h: hard error reading fsbn

3247423; cn 5181 tn 232 sn 42) status=59 error=40

I have searched Google to find a solution to mark off these two
blocks/inodes (or however I should call them), so that they will not
be used anymore. All I found is that this is not possible on
IDE. Advise: Throw away the disk. Now this I find a bit radical :-)
Esp. since the disk is about 3 years old.

Any advise other than throw away the disk (or claim a new one)? Is
there really no way to tell FreeBSD to discard these sectors?

One more detail: Last time the machine booted it thought this of the
drive:

Jan  8 12:28:58 zeist /kernel: ad0: 39083MB <Maxtor 5T040H4>

Thanks!
