Sender: owner-questions@freebsd.org X-Loop: FreeBSD.org Precedence: bulk I have looked through all the FreeBSD FAQ and searched the website for answers but am still unable to fix this problem. I have two disks both of which are Micro1991 (I know - i have heard bad things about these disks but you got to give them the benefit of the doubt). One disk works happily because freebsd has managed to install on this disk (sd0) but the other is having problems. SD0 information is:- pepper# scsiformat -p c sd0 MICROP 1991-27 1128RF 28RF Mode data length: 35 Medium type: 0 Device Specific Parameter: 0 Block descriptor length: 8 Density code: 0 Number of blocks: 978576 Reserved: 0 Block length: 512 PS: 1 Reserved: 0 Page code: 4 Page length: 22 Number of Cylinders: 4476 Number of Heads: 27 Starting Cylinder-Write Precompensation: 0 Starting Cylinder-Reduced Write Current: 0 Drive Step Rate: 0 Landing Zone Cylinder: 0 Reserved: 0 RPL: 0 Rotational Offset: 0 Reserved: 0 Medium Rotation Rate: 5400 Reserved: 0 Reserved: 0 Parition information of SD0 is:- pepper# disklabel sd0 # /dev/rsd0c: type: SCSI disk: sd0s1 label: flags: bytes/sector: 512 sectors/track: 32 tracks/cylinder: 64 sectors/cylinder: 2048 cylinders: 8668 sectors/unit: 17754080 rpm: 3600 interleave: 1 trackskew: 0 cylinderskew: 0 headswitch: 0 # milliseconds track-to-track seek: 0 # milliseconds drivedata: 0 8 partitions: # size offset fstype [fsize bsize bps/cpg] a: 204800 0 4.2BSD 0 0 0 # (Cyl. 0 - 99) b: 409600 204800 swap # (Cyl. 100 - 299) c: 17754080 0 unused 0 0 # (Cyl. 0 - 8668*) e: 819200 614400 4.2BSD 0 0 0 # (Cyl. 300 - 699) f: 2048000 1433600 4.2BSD 0 0 0 # (Cyl. 700 - 1699) g: 14270464 3481600 4.2BSD 0 0 0 # (Cyl. 1700 - 8667) I have configured SD1 to be the same as SD0 but when it comes to newfs it it complains about superblock backups at about 13370960 12976160, 13041696, 13107232, 13172768, 13238304, 13303840,write error: 13370960 wtfs: Input/output error The parition inforamtion for this disk SD1 is :- 4 partitions: # size offset fstype [fsize bsize bps/cpg] a: 17752064 0 4.2BSD 0 0 0 # (Cyl. 0 - 8667) c: 17754080 0 unused 0 0 # (Cyl. 0 - 8668*) Does anyone have any clues what the problem is ? Could it be that newfs is trying to write to areas that don't exsist or is the parition table incorrect ? Any help would be greatly appericated. Thanx in advance. Tony -- Little Tony........
