failing disk, or not?

["George Georgalis" <george@xxxxxxxxx>]

I'm seeing some disk errors in dfly that I cannot reproduce with other
OS checking the partition:

ad4: UDMA ICRC error writing fsbn 249842603 of 110387664-110387679 (ad4 bn 249842603; cn 15551 tn 250 sn 38) retrying

This happened while running dvdbackup and I reproduced it running
a dd read from the partition. However, after several attempts I cannot
reproduce it from Linux badblocks (read or non-distructive write) check
or linux dd read from the partition. I know failures can be intermetint
But not getting any errors at all yet, from Linux, seems odd at this
point, if the disk is really failing.

# df -h
Filesystem    Size   Used  Avail Capacity  Mounted on
/dev/ad4s3a   248M   122M   106M    54%    /
/dev/ad4s3d   248M   1.3M   227M     1%    /var
/dev/ad4s3e   124G    94G    20G    83%    /usr
procfs        4.0K   4.0K     0B   100%    /proc

A bit of history, I did have a system lockup -- I could switch virtural
terminals but no keyboard input was accepted -- a week or two ago,
didn't file bug because I was half-hazard experimenting (in user space)
and couldn't explain well enough, at the time all I was doing, now I
don't even remember. A fsck was required, and with a 95Gb /usr, that
took quite a while. (welcome comments on why softupdates didn't help
here), also the /usr partition was near or over 100% capacity, but I
never got disk full errors, ie didn't *completely* run out of space.

At this point can I be sure my disk is failing or could there be some
driver instability? The full dmesg is below.

Don't see it in dmesg, but ad4 is a 200Gb Seagate drive, on a nvidia
sata controler.  Disk Product Number ST3200822AS, Part Number 9W2854-301

Thanks,
// George
