Disk /dev/sdb doesn't contain a valid
partition table
[root@nfs ~]# fdisk
/dev/sdb
Device contains neither a valid DOS
partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel. Changes will
remain in memory only,
until you decide to write them. After that,
of course, the previous
content won't be recoverable.
The number of cylinders for this disk is
set to 1044.
There is nothing wrong with that, but this
is larger than 1024,
and could in certain setups cause problems
with:
1) software that runs at boot time (e.g.,
old versions of LILO)
2) booting and partitioning software from
other OSs
(e.g., DOS FDISK, OS/2 FDISK)
