forse ho trovato qualcosa, sto provando con gpart

codice:
Begin scan...
Possible partition(DOS FAT), size(1004mb), offset(0mb)
Possible partition(Windows NT/W2K FS), size(6204mb), offset(1004mb)
Possible partition(Windows NT/W2K FS), size(67334mb), offset(9005mb)
End scan.

Checking partitions...
Partition(Primary 'big' DOS (> 32MB)): primary
Partition(OS/2 HPFS, NTFS, QNX or Advanced UNIX): primary
Partition(OS/2 HPFS, NTFS, QNX or Advanced UNIX): primary
Ok.

Guessed primary partition table:
Primary partition(1)
   type: 006(0x06)(Primary 'big' DOS (> 32MB))
   size: 1004mb #s(2056257) s(63-2056319)
   chs:  (0/1/1)-(1023/15/63)d (0/1/1)-(2039/15/63)r

Primary partition(2)
   type: 007(0x07)(OS/2 HPFS, NTFS, QNX or Advanced UNIX)
   size: 6204mb #s(12707344) s(2056383-14763726)
   chs:  (1023/15/63)-(1023/15/63)d (2040/1/1)-(14646/8/55)r

Primary partition(3)
   type: 007(0x07)(OS/2 HPFS, NTFS, QNX or Advanced UNIX)
   size: 67334mb #s(137901897) s(18442683-156344579)
   chs:  (1023/15/63)-(1023/15/63)d (18296/5/1)-(155103/11/63)r

Primary partition(4)
   type: 000(0x00)(unused)
   size: 0mb #s(0) s(0-0)
   chs:  (0/0/0)-(0/0/0)d (0/0/0)-(0/0/0)r
i valori dei chs sono quelli che mi servono, ora riavvio e li confronto con quelli di ranish... incrocio le dita
