fedora boot failed: can't mount root filesystem.

Hello :
My Fedora 12 System was failed when booting.The message like that :

mount: wrong fs type, bad option, bad superblock on /dev/mapper/my_vol
missing codepage or helper program, or other error.
In some case, useful info is found in syslog - try
dmesg | tail or so

Can't mount at root filesystem.
[drm: drm_mode_rmfb ] *ERROR* tried to remove a fb that we didn't own.

Boot has failed, sleep forever.

I guess something wrong with my hard disk, so the bootloader can't recognize the filesystem type. Am I right? And how to deal with the problem. Thanks.

Please don't post in such a large font-face.

And you're right, it seems like your drive has died. And how you deal with it, is replace the bad drive, reload the operating system, and restore your data from backups. That's the only thing you can do, same as with Windows, Mac, or any other OS. Replace dead hardware, restore from backups and move on.

However, there could be other causes, but you don't say what kind of disk hardware (RAID, etc.), or if you're using LVM's, etc.

I'm sorry, I won't use big font agin. But yesterday I found a page
https://bugzilla.redhat.com/show_bug.cgi?id=539709.
In fact, I'm using a USB harddisk just like the page said. Maybe it's the time to buy a new one.
