I have been running freebsd for quite a while now and I just bothered to look at the disklabel info. Funny since I once installed a Dec Alpha system with OSF and the disklabel was the worst part of the install program (you couldn't change a thing). So now I look in the file at see the following. type: SCSI disk: sd0s2 label: flags: bytes/sector: 512 sectors/track: 63 tracks/cylinder: 255 sectors/cylinder: 16065 cylinders: 455 sectors/unit: 7309575 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: 65536 0 4.2BSD 0 0 0 # (Cyl. 0 - 4*) b: 409600 65536 swap # (Cyl. 4*- 29*) c: 7309575 0 unused 0 0 # (Cyl. 0 - 454) e: 61440 475136 4.2BSD 0 0 0 # (Cyl. 29*- 33*) f: 6772999 536576 4.2BSD 0 0 0 # (Cyl. 33*- 454*) Well, nice it got all the drive info without asking me (Quantum Atlas 4.2gig FW). But why does it have 0 for fsize and bsize? This is really weird. I can't seem to figure out the filesystem blocksize anywhere (haven't checked the source yet though). Is it really a 4.2BSD filesystem? I will need to change the rpm if that does any good. My disk just seams a little slow. Any where I can find technical information about FreeBSD filesystems would be helpfull. I would like to use the lastest version is 4.2BSD it? Thanks for the info. dicen
