Nope, of course raid-1 and both disks were my first suspects but I found
nothing in log files suggesting any raid failure or strange things
involving one or both HDz, I also never lost a file or a directory.

There's a script doing this that sends an e-mail in case of problem
but it was never activated.

RAM is also ok, so my latter suspect is the power supply.
I first dismissed it because it was no as old as the machine, but I
already saw that in SOHO machines like this one (mostly because
capacitors are never oversized compared to pro PSUs.)

Thanks anyway,
