Hi all. I don't know a lot about RAID, but someone brought me a computer that was setup with a RAID 1 array. It's not a RAID 0 array, for speed. This is a RAID 1 array, for redundancy. And I'm sure about that. I mention this because in all the posts concerning RAID, there are many responses along the lines of, "Which type of RAID array is it?," and "if it's a RAID 0 then there's no way you can recover the data". It's a RAID 1 array.
Now that I have that established... here's the deal. The operating system totally crashed and the RAID array stopped working. It doesn't appear to be the result of any kind of physical damage to either of the disks (which are 180GB Seagate SATAs). But some very weird things are going on.
On the master disk, there's a 60GB partition showing, and 120GB of unpartitioned space.
On the slave disk, there's a 180GB partition which contains data. Though none of this data can be seen by the OS--it can only be seen by a file recovery program.
On the master disk, some of the data can be seen by the OS, but the majority can only be seen by a file recovery program. We recovered about 35 GB of data on the master disk. This was all good data that wasn't corrupted or compressed.
On the slave disk, we've found about 100GB of data with the use of a file recovery program. According to the owner of the computer, there should be about 100GB of data stored on the array. All of this data is corrupt. I mean, files can't be opened using the normal programs that would open them. Text files are full of binary characters. What's odd, though, is that I've found bits of text in binary files, like MS-Word documents, which contain some strings of readable text, even though they're binary files.
My question is, is the data on the second drive compressed or encoded by some special RAID process? And if so, how can we decrypt it. Or are we going to have to setup a RAID array again to be able to recover the data?
Thanks in advance,
