To be honest I think the drives are fine but the system is just soooo old including the IDE drives. I mean if I get a SATA/IDE USB adapter I should be able to backup the drives to the new DAS system I will have in place shortly since I am much more in favor of running Nexenta Core 3 OS with ZFS spanning the 16x drives meaning a total of 36TB with 2 internal drives used for logging and caching. Then this system will be obsolete. However, I will keep your suggestion of using *spinwrite* in mind next time I encounter issues! BTW I respect your H/W knowledge that's quite in deep :-) thank you for your insight. Best regards, Kaya
