I've been thinking about R-Studio especially since it claims it can work on RAID volumes as a set without needing the controller. The disk doesn't contain a complete filesystem by itself but the RAIDset as a whole should theoretically have all the data – at least that's my going theory.

I'm looking for good tools to do a low(ish)-level volume scan looking for things like MySQL databases, etc. It doesn't look like there was any physical disk damage – the RAIDset came back online when I forced the disks back to OK – but I'm definitely missing some file indices. Does anyone have any recommendations? If I understand you, you have a disk that is not damaged physically, but the file system is damaged. Given that this is a raid 5 system, the disk doesn't contain a complete filesystem, does it? If it does, then r-studio is a great utility for digging into messes and extracting files. But I don't think it can help out if this is part of a raid system. I hope I'm wrong on this. --STeve Andre'
