In my previous job I had spent quite a lot of time pounding these disks; mostly the 600MB 5.25" variety, but also some of the larger units. I would expect that the smaller 3.5" units are comparable, but I haven't had much exposure to them. We were using Ricoh and Sony mechanisms close to 10 years old, with disks as old or older. They're incredibly robust provided you keep them clean. Cleaning them isn't too hard either, as long as you do it properly. -- \\ Sometimes you're ahead, \\ Mike Smith \\ sometimes you're behind. \\ mike@smith.net.au \\ The race is long, and in the \\ msmith@freebsd.org \\ end it's only with yourself. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
