Hey, I recently installed FreeBSD4.3, and I noticed my harddrive seems to be running slower than it has done under Windoze and Linux. I ran 'disklabel ad0' and it told me that my rpm of my HD is 3600, which is wrong; the drives only 9 months old. If I run 'disklabel -e ad0' and changed the rpm manually, will it speed up the drive, or could it damage it instead? (Thought I'd better check before I tried.....) Is there any other ways to speed up the HD, like doing something funky with DMAs? Output of 'disklabel ad0': # /dev/ad0c: type: ESDI disk: ad0s3 label: flags: bytes/sector: 512 sectors/track: 63 tracks/cylinder: 240 sectors/cylinder: 15120 cylinders: 641 sectors/unit: 9691920 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 1024 8192 16 # (Cyl. 0 - 13*) b: 1056624 204800 swap # (Cyl. 13*- 83*) c: 9691920 0 unused 0 0 # (Cyl. 0 - 640) e: 102400 1261424 4.2BSD 1024 8192 16 # (Cyl. 83*- 90*) f: 1024000 1363824 4.2BSD 1024 8192 16 # (Cyl. 90*- 157*) g: 7304096 2387824 4.2BSD 1024 8192 16 # (Cyl. 157*- 640*) Thanks, Chris Pearce.
