Dear Dell OptiPlex 755 Specialist,
I have tried to use a decommissioned Dell OptiPlex 755 mini-tower that was functioning at work, but found that it no longer detect any SATA devices during boot up, despite have detected in F2 BIOS as follows:
SATA-0 (On), Drive-ID: WDC WD1600AAJS-75M0A02, Capcity: 160GB, Controller: Serial ATA, Port:SATA-0, BIOS: Control by system BIOS.
SATA-1 (On), Drive-ID: OPtiarc DVD+/-RW AD7200S, Controller: Serial ATA, Port:SATA-1, BIOS: Control by system BIOS.
SATA-2 (On), Drive-ID: Hitachi HDS721616PLA380, Capcity: 160GB, Controller: Serial ATA, Port:SATA-2, BIOS: Control by system BIOS.
SATA Operation: RAID Autodetect / ATA
However, the following hardware detection is displayed during bootup:
Primary Channel:
IBM-DTLA-307045 38,166MB (IDE drive attached to RAID controller)
Drive 1 not found
Secondary Channel:
Drive 0 and 1 not found
Below is the outcome from F5 diagnostic test:
Hard Drive – DST Short Test
Test Results – Fail
Error Code: 0146
Msg: Error Code 2000-0146
Msg: Unit 1: DST Log contains previous error(s).
There are powered to all these devices and I have replaced them with different SATA data cables, including swapping the data cable on different SATA connector on motherboard without success. Both hard drives & DVD drive are working.
The only thing that has changed was I had to carry this computer by foot for 1km together with catching train to take it home, not sure whether this would have damaged it in some way.
Thanks in advance,
George
