A bit OT, but maybe related: I have similar strangeness with a Linux
box=20
with Areca controller. On this box, the reiserfs filesystem starts=20
getting seriously damaged after some time. Memtest showed no problems,=20
and everything looks fine. Today we will replace the mainboard, it=20
could have an internal problem (trans****t from memory to controller=20
broken?).
What I had twice (on different customers, once SCSI once SATA) is that
a=20
broken hard disk re****ts no errors, but delivers different data than=20
what was written before. Very nasty, as the RAID controller doesn't see=20
any problem, and destroys even the good harddisks data after the next=20
write, because the read data is already broken.
HTH, good luck.
