I'm resigned to RMA/replacing at this point, but for educational purposes, how does a SATA controller "die"?
A few nights ago, my home-built workstation was idling and froze. I restarted by holding the power button on the PC case; the OS wouldn't boot, and now here I am. The BIOS won't recognize any SATA devices except the DVDRW drive. None of my HDs or SSDs are visible. The BIOS will recognize USB devices, but the boot loader will not. I don't have an IDE port.
OS = Ubuntu 12.04, kernel 3.13.5 updated 7 days prior to crash
Mobo = AsusP8Z68-VLX BIOS = American Megatrends ver 4105 (most recent) CMOS = reset by reseating battery (tested at 3.0/3.0 V)
RAM = 4x 2Gb Kingston DDR3 1600 MHz - verified working in BIOS
2x Western Digital 500 Gb SATA HD - verified working
1x OCZ 30 Gb SATA SSD - verified working
2x 6 Gb/s - verified working
4x 3 Gb/s - verified working
BIOS will recognize my DVDRW in any port, but will not recognize any other drive. It also sees my SMI multicard reader, but won't recognize any media in the reader.
AHCI = drives undetected
IDE = drives undetected
RAID = drives undetected
UEFI = drives undetected Legacy = drives undetected
Coolmax 850W = verified working
Surge protected Belkin power strip on 120VAC, 15A circuit with 6 other small consumer electric devices (on the whole circuit, not the strip)
Command Results (from Ubuntu live CD)
lsusb = shows all devices
lspci = shows all devices
lsscsi = shows DVDRW, card reader, all USB
fdisk -l = returns nothing
gparted = /dev/sda1 3.73 GiB (this is the DVD holding the .iso)
So, the BIOS won't see any SSD/HD. I'm resigned to RMA/replacing at this point, but for educational purposes, how does a SATA controller "die"? Or, what else might have happened?
