Disk /dev/sdb doesn't contain a valid partition table
NOTE
Step 5 In this example, the command fdisk /dev/sdb is used to partition the logical disk sdb of the AS
(set according to the actual situation). The following information is displayed.
Command (m for help): n Command action e
Partition number (1-4): 1 First cylinder (1-1011, default 1): 1 Last cylinder
(1-1011, default 1): 1011
Command (m for help): w The partition table has been altered!
Calling ioctl() to re-read partition table. Syncing disks.
Step 6 In this example, the command mkfs.ext3 /dev/sdb1 is used to create a file system for sdb (set
according to the actual situation). The following information is displayed.
mke2fs 1.38 (30-Jun-2005) /dev/sdb is entire device, not just one partition!
