Most likely something in the Kernel got them mucked up.  Or your
hardware is junk.

No, XFS would be my first suspect with LVM a close second, and hardware
a third.  I'd eat my hat if Samba had anything to do with this other
than dispatching a write request (which it is the kernels job to deal
with sanely).  Samba or other applications do not deal with disk
geometry.

Why?

False.

Why?

What does this mean?  Of course they "care about files"

Ah, IDE hardware.  So that puts it solidly on the suspect list.

> something to do with Samba

EXTREMELY doubtful.
