Da root eseguiamo una rapida verifica con fdisk:

# fdisk -l
Disk /dev/hda: 8589 MB, 8589934592 bytes
255 heads, 63 sectors/track, 1044 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00000000

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

Dal precedente comando abbiamo verificato che, in questo caso, le partizioni salvate si trovano sull'hdb mentre l'Hard Disk vergine (senza partizioni) è l'hda. Ripristiniamo su quest'ultimo le due partizioni iniziali. Per fare ciò dobbiamo:

1. avviare l'utility fdisk su /dev/hda;
2. aggiungere una prima partizione di 200M;
3. aggiungere una seconda partizione primaria su tutto lo spazio disponibile;
4. assegnare alla seconda la descrizione di tipo di partizione LVM.

# fdisk /dev/hda
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)

Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.
