Disk /dev/sdb doesn't contain a valid partition table

xxx@xxx:/dev$ sudo fdisk /dev/sdb

Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel

Building a new DOS disklabel with disk identifier 0xdc2cc610.

Changes will remain in memory only, until you decide to write them.

After that, of course, the previous content won't be recoverable.



Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
