Here's the last smart report from two of the offending drives. As noted before, I did the hardware reorganization, replaced the dog slow 3ware 9500S-8 and the SiI 3124 with a single Areca 1130 and retired the drives for now, but a nephew already showed interest. What do you think, can I cede those drives with a clear conscience? The Hardware_ECC_Recovered values are really worrisome, aren't they? sdc: smartctl version 5.38 [i686-suse-linux-gnu] Copyright (C) 2002-7 Bruce Allen Home page is http://smartmontools.sourceforge.net/ === START OF INFORMATION SECTION === Model Family: SAMSUNG SpinPoint P120 series Device Model: SAMSUNG SP2504C Serial Number: S09QJ1GYA03006 Firmware Version: VT100-33 User Capacity: 250.059.350.016 bytes Device is: In smartctl database [for details use: -P show] ATA Version is: 7 ATA Standard is: ATA/ATAPI-7 T13 1532D revision 4a Local Time is: Sun Mar 23 01:13:37 2008 CET ==> WARNING: May need -F samsung3 enabled; see manual for details.

There hasn't been any similar problem on sata_sil24. Hmm, I didn't noticed any data distortions, and if there where, they live on as copies in their new home..
