Sorry if my frustration is showing through but I am attempting to not only learn Unix but to make a system work dependably. My job depends on it. This "can't mount root" problem has happened three times to what seems to be a perfectly working system, not a new install. It seems that something that occurred on my IDE drive, destroyed the superblock on my SCSI drive, even though they have seperate controllers. I have now taken to unplugging the SCSI drive when I work in dos and disabling the IDE drive when I sprk in UNIX. Effective but annoying. My freeBSD system resides only on the SCSI 1gb drive and my dos system is only on the IDE drive. I did the install this way as I was told here that this was the only way to ensure that my dos system wasn't trashed. That is very important to me as I have 6 hours of backup/restore to do every time the BSD trashes the dos system (and it did it every time I tried to install the BSD OS). As far as the geometry is concerned, several people here have told me that a SCSI drive that does not share space with another OS, does not need geometry information. Please let me know if that is wrong. Anyway, I've wiped the drive once again and put 2.1.5 up on it. The superblock was trashed. I have several hundred dollars worth of Unix texts now but I need a reference for disk restructuring in case of this kind of failure. Any help woould be appreciated. Dave Blizzard
