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

Building a new DOS disklabel with disk identifier 0x6105d121.

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').
