I have a computer with 4 hard drives built in a RAID 5 array. Powering on the computer to get a disk boot error message.
The raid controller is only recognizing 3 of the 4 hard drives.
I loaded an optimized bios and enabled raid options. Still getting Disk boot failure, insert disk, enter.
Checked cables and all are connected to HD’s and motherboard appropriately.
Motherboard has a 6 SATA device capacity; so I moved the cables around in the 6 slots; then used the BIOS SATA enabled/disabled function to adjust for all 4. Disk boot failure message still persists.
Went through BIOS in onboard device configuration and disabled one of the 4 SATA drives, then rebooted. Used this process on each HD separately. 3 of 4 HD’s reported a “degraded array” warning when I did this. Disabling the BIOS for the 1 HD, produced no warning — Array reads as healthy. Same Disk boot failure message.
My thought is that HD #1 has either: suffered some unfortunate loss of boot files, or has failed and needs to be replaced and the array rebuilt.
Since a RAID 5 can run on 3 HD’s, is there a way to configure just these drives to work together and boot without compromising data?
Is the only solution to rebuild from a new, identical HD?
