Just look at the outputs from fdisk and disklabel and they will tell you. Presuming your disk is device da0 (first SCSI disk), type: fdisk -s da0 lists the number of blocks/sectors in each slice. Then disklabel -r da0s1 lists the number of blocks for each partition in slice 1 of that disk. If the disk is other than the first SCSI disk you will need to use the appripriate device, such as da1 for the second SCSI disk or wd0 or whatever for IDE (I don't have any IDE disks to look at right now). If that 10 GB slice is not the first slice you will need to use a different number with the 's' in the disklabel command - such as da1s3 would be the second SCSI disk drive and the third slice on that disk. Then realize that blocks/sectors are 512 bytes and Megabytes are 1048576 bytes or 2048 blocks (not 1,000,000 bytes) GigaBytes are 1073741824 bytes or 2097152 blocks (not 1,000,000,000 bytes). BUT NOTE that manufacturers rate their drives using 1,000,000 bytes as a Megabyte and 1,000,000,000 bytes as a Gigabyte so there is quite a difference between what the vendor claims and what the system claims the disk will hold. ////jerry > > > James Leone > > _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
