LVM, RAID0 or hard-drive failure.


Dear all,
woke up in the morning and Fedora Core 7 couldn't boot (in addition video card burnt).
I have three hard drives
160G IDE
80G SATA
80G SATA
Two sata drives most likely in raid0 configuration. All three are in LVM. The data on hard drives is important. Please tell me whether it can be at least partially restored?
Now I run Knoppix on live cd on that computer.
Here is the dmesg output.


Thanks in advance.
