Your
clear and easy-to-follow instructions are exactly what I have been looking for. I think this disk is finally formatted properly:
Code:
$ disklabel -h sd1
# /dev/rsd1c:
type: SCSI
disk: SCSI disk
label: BUP Slim BK
duid: 0000000000000000
flags:
bytes/sector: 512
sectors/track: 63
tracks/cylinder: 255
sectors/cylinder: 16065
cylinders: 243201
total sectors: 3907029167 # total bytes: 1.8T
boundstart: 0
boundend: 3907029167
drivedata: 0
16 partitions:
# size offset fstype [fsize bsize cpg]
c: 1.8T 0 unused
i: 1.8T 64 MSDOS
Code:
$ fdisk sd1
Disk: sd1 geometry: 243201/255/63 [3907029167 Sectors]
Offset: 0 Signature: 0xAA55
Starting Ending LBA Info:
#: id C H S - C H S [ start: size ]
-------------------------------------------------------------------------------
*0: 0C 0 1 2 - 243200 254 63 [ 64: 3907024001 ] FAT32L
1: 00 0 0 0 - 0 0 0 [ 0: 0 ] unused
2: 00 0 0 0 - 0 0 0 [ 0: 0 ] unused
3: 00 0 0 0 - 0 0 0 [ 0: 0 ] unused
I have a few final questions:
Will this disk be readable by any machine running Linux or Windows? This will be a backup drive. If something happens to my OpenBSD machine, I want to be able to read and possibly restore my files to another location.
I noticed that the offset of partition "i" and LBA start values have changed from 32 to 64. Does that make a difference?
I'm also wondering how you learned the process for formatting disks. I will probably have to format additional drives on OpenBSD at some point in the future, and I'd really like to be confident that I have the knowledge to do so correctly.
