ok allora se faccio fdisk -l ottengo questo:

codice:
Disk /dev/hda: 40.0 GB, 40016019456 bytes
255 heads, 63 sectors/track, 4865 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
                                                                                
   Device Boot    Start       End    Blocks   Id  System
/dev/hda1   *         1        13    104391   83  Linux
                                                                                
Disk /dev/hdb: 80.0 GB, 80060424192 bytes
255 heads, 63 sectors/track, 9733 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
                                                                                
   Device Boot    Start       End    Blocks   Id  System
/dev/hdb1   *         1      9479  76140036   83  Linux
/dev/hdb2          9480      9733   2040255   82  Linux swap
se poi faccio fdisk /dev/hdb per creare modificare la partizione ottngo quest'altro invece:

codice:
The number of cylinders for this disk is set to 9733.
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)
 
Command (m for help):
efettivamnte prima quello era un disco con partizionamento NTFS di win 2000 ma quando ho installato il sistema gli ho anche detto do cancellarmi tutte le partizioni e formattarmi i dischi con un filesystem adeguato a linux...

che faccio ora?

grazie
