# fdisk /dev/vdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a
new
DOS disklabel
with
disk identifier 0xb5f18769.
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)
WARNING: DOS-compatible mode is deprecated. It'
s strongly recommended to
switch
off the mode (command
'c'
) and change display units to
sectors (command
'u'
).
