October 5, 201411 yr It looks like I have a damaged MBR on one of my disks related to a faulty PSU. I have 3 other identical disks in my array. Is it possible to use 'DD' to backup the MBR from a healthy Disk and restore it to replace my damaged one? Would the MBRs be identical for identical model disks bought at the same time? I've been reading on ubuntu forums how to do this, but if there's a better way to replace a corrupt MBR on an unraid disk I'd love to know the solution. Before anyone suggests I just replace the disk I'm still hoping it'll allow me to parity rebuild recover some data from a different disk that also had problems. I have 2 failed disks, this one seems like just the MBR. Thanks, Mark.
October 6, 201411 yr Author Does anyone have a good suggestion how to fix a damaged MBR when I can't rebuild the disk? I'm ready to try to copy the MBR from an identical make/model disk purchased at the same time, but is there information held within the MBR that is specific to that physical disk? I've read the the volume label may he held in there. IF so is that something I get get around? Thanks, Mark.
