I have just added a second WD 1Tb disk to my desktop system for backups and such.
It *looks* like the one that the system started with but it has some subtle differences and I wonder whether these are significant in any way.
Firstly fdisk reports slightly different geometry:-
Disk /dev/sdb: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xf24a2de7
Disk /dev/sdc: 1000.2 GB, 1000204886016 bytes 81 heads, 63 sectors/track, 382818 cylinders Units = cylinders of 5103 * 512 = 2612736 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x4e451e03
Secondly (and the one I have *slightly* more concern about) blkid reports as follows:-
/dev/sdc1: UUID="c4ae6fbe-18b3-4af9-aed8-a442e0fb6893" SEC_TYPE="ext2" TYPE="ext3" /dev/sdb1: UUID="6976542f-0471-411e-8c0d-97492c3f49b5" TYPE="ext3"
What does that SEC_TYPE="ext2" mean? I used mkfs.ext3 to create the file system on the disk with no explicit option. Presumably the other disk (/dev/sdb1) was partitioned and formatted when I installed xubuntu.
