Missing disk...

One of my disks pulled a Houdini (vanished).

We had an electrical storm last night. The computer was off, but it was plugged in.

It has 3 disks, each has OS's on it. 2 will boot, but the 3rd "does not exist", says GRUBloader.

If the machine powered off without proper dismount, would this be the result? How would I fix this?
Below is hardware, RED highlight is the question...

No. "Dismount" is a filesystem operation (data) and has nothing to do with the physical operation/status of the HDD. If the drive doesn't show up in a HW or BIOS scan, it's toast.

BIOS

Quote:

The initial function of the BIOS is to identify, test, and initialize system devices such as the video display card, hard disk, and floppy disk and other hardware.

GRUB is a bootloader and nothing more.

Nearly any bootable card will post following the motherboard's BIOS initialization - I have never seen one that doesn't. Most also have an option to enter the configuration menu for the card as well during initialization.

Google is your friend.

Silicon Image 0680 Docs

From "medley manual:"

Quote:

Creating and deleting RAID sets is a function found in the BIOS. During bootup, the following message
will appear, pausing for a few moments to allow the user to choose what to do:
Press F3 to enter RAID utility

This indicates that the card does post and does show up following the motherboard's BIOS routines.

Now, I've pulled the disk, plugged it into an external USB enclosure, powered up, and the disk spun up. Plugged it into another machine, powered THAT machine up, and the GRUB menu from the EXTERNAL disk displayed. SO, since the RAID function was recognized on the other machine, it is either a faulty molex connector (PSU), OR, a bad IDE cable). No testing besides switching parts, I presume...

It could be that the card is failing, it could be that the HDD is failing, or it could be a random strange event and it runs fine for years to come. I would watch the messages file for any HW messages and turn on the SMART daemon to make sure the HDD is monitored.

We had a lengthy power failure and after some time my UPS shut off, resulting in a hard power down of the system, while I was in the process of shutting it down rationally of course. Fortunately, the damage to the file systems was repairable, but for some reason the USB hub in one of my monitors got toasted. I had to spend about 3 hours on the line with Dell to convince them that the USB hub was indeed toast and they need to send me a new monitor (it's still under warranty, fortunately). I'm thinking of sending them a bill for wasting my time... __________________ Sometimes, real fast is almost as good as real time.
