I restarted the machine with spare hard disk and previous night backup, but I have no backup for the emails received during the last day. I cannot do a low level SCSI verify, it may be that all spare sectors have been reallocated. I cannot run an fsck. I am wondering if there is a way to read the physical blocks (those that are readable) and save the data, from that I could be able to rebuild some of the mailboxes. Best regards, Olivier
