Dashboard corrupted

Thank you for your effort but I already went further than that. BTW, ext2fsd handles also ext4. I have already did all recovery steps listed in the de-bricking guide you cited. The data is definitely gone. At this moment it seems that the MBLD software caused the disaster. For unknown reason, it went into initialization mode and destroyed file systems on entire RAID 1 array. Because I do not know what caused it, I am not going to take risk of using it MBLD again. I dismounted drives, I will perform physical formatting and reuse drives for other purposes. Currently, I am migrating data from other two MBLDs to avoid further loses. I’m done with MBLD.
