Do you > think I should try? If I were you, I would first buy/get a XXX GB SATA drive, create a filesystem there and copy all three disks block-by-block as three separate files (which will be the size of the disks). This way you'll still have the backup of your screwed up drives somewhere in case something goes even more wrong. However, I don't think your data is *physically* lost. I am almost sure that it is still on that drives, only the metadata could be fscked up. Now how to get the data back is another thing. In worst case scenario you could analyze the specification of the metadata format for you controller and then write a C program which would somehow put the bits together again using syscalls. Bye, Nejc
