I really don't think anything messed
with the bios, they usually require some kind of specific driver
or method to chat with the bios, usually relying on the vendor to
create a linux binary, or at the bios level, to update the
firmware. I wish I could automagically update the bios, it's
usually a pain.
You might consider booting the drive on a usb to sata adapter on a working system, or whatever format the disk is, to see if another os sees it even inserted. Usually you'll get some sort of dmesg spew about this and that as it inserts and probes the hardware. If linux/grub doesn't see it at all, it's usually damaged. Worst case you'll usually get /dev/sd[a|b|c] inserted message, which is linux understanding how to probe the hardware, and subsequent enumeration of your partitions if possible as /dev/sdX[1|2|3] as the partition. A live cd should see some form of /dev/sdX drive aside from the usb. If you see /dev/sdX without the number, and some grumbling about missing partitions, likely it wiped your data enough wipe from sector 0 at least as you let it run. I'm thinking it isn't seeing your partition/mbr, etc, but probably sees /dev/sdX without at least /dev/sdX1 meaning you wiped your data. Does the bios see it on the sata bus? If so, the disk should be OK as long as you can rewrite the partition or access it without ata failures. Only other thing is maybe a bug in the kernel not seeing a legacy adapter or something buggin' it out. Maybe a different distro with an older kernel? I have booted a newer kernel that didn't see old devices before for whatever malfeasance there was (usually stupid video card/driver issues tho, never a disk). I did have crappy disk firmware update utility from linux nuke my Adata ssd with an upgrade binary to fix the disk from linux that was here today, gone tomorrow once invoked on my drive. Their crack(head) tech support promply ignored me too, but again, requires some sort of binary interaction that is far from default on a disk utility to automagically update bios or firmware to a disk or mobo. Dmesg just would give ugly kernel messages of sata timeouts beyond that - to the garbage pile and blacklist of vendors to buy disks from. I just lost another ssd, apparently an equally crappy Crucial m100 disk after 2 months that gave out showing me no partitions and ata timeouts, so maybe bad luck of it just giving out on a cleansing? Every disk seems to die in different ways, especially with the advent of ssd's. -mb On 12/15/2014 05:59 PM, Michael Torres wrote:
