Hi all,

I've experienced some disk corruption on my laptop.

Scenario:
I'm cross-compiling tons of sources and I felt the need
to insert a CompactFlash card (via PCMCIA) in my laptop.
So I did, no problem: 
mounted, touched a file, umounted, cardctl-ejected.

Pretty soon my compilation stops:
bash: /usr/bin/sort: cannot execute binary file

Okey. The date on /usr/bin/sort is unchanged. Must be root to write.
I am NOT compiling as root. 
"File" on /usr/bin/sort says "data". No elf.
The only thing that the logs say:

modprobe: Can't locate module binfmt-464c

The filesystem on /usr is ext2.

I downloaded a new textutils.deb and installed it.
(But I made a backup of the corrupted file for some reason)
Searched the net and found some previous problem with
2.2.10 and DMA + CompactFlash.
Started to write a mail like this. 
Tried to do a ls -> Segmentation fault.
Then the entire machine crashed.
I rebooted the machine and fsck.ext2 complained about
my largest partition, did a manual check and now I'm back.

I wonder how many corrupted files there are left...

The machine is usually very stable, but I haven't done
much PCMCIA activity with it.

Maybe this is not even related to PCMCIA...

Anyway, this is what I do to my disk/controller:

/sbin/hdparm -c1 -d1 -m16 -a0 -S4 -u1 /dev/hda

I don't know if that has anything to do with it.

I've used this computer about three months now
and another Portege (3440CT) six months.
Never experienced anything like that...

So, all Portege users out there - be careful!

Cheers /

Magnus
