But what's strange for me is, that I preformatted the > disk 12 hours ago ... And then this, hmmm ... Er, rule 1: Do not perform a SCSI format on a disk unless you absolutely *MUST*. Disks are formatted at the factory under optimal conditions. You can't reproduce those anywhere else. rule 2: If you have to perform a format, run the disk (properly cooled and mounted) for at least an hour before starting the format. Failure to do this will almost certainly result in a poor format. Also, your error is not uncommon; if the media has lost some retention it will be OK during the format, but hours later the data will be gone. -- \\ 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-scsi" in the body of the message
