disk free space

[Roberto Bernetti <bernetti@inwind.it>]

Hi
I'm using a PW 500au with Debian woody. During the booting process the disk is 
labelled with 4GB of space (like during the patition process):

qlogicisp : new isp1020 revision ID (5)
scsi0 : QLogic ISP1020 SCSI on PCI bus 01 device 20 irq 27 I/O base 0x9000
scsi : 1 host.
  Vendor: DEC       Model: RZ2CC-KB (C) DEC  Rev: DC2B
  Type:   Direct-Access                      ANSI SCSI revision: 02
Detected scsi disk sda at scsi0, channel 0, id 0, lun 0
scsi : detected 1 SCSI disk total.
SCSI device sda: hdwr sector= 512 bytes. Sectors= 8380080 [4091 MB] [4.1 GB]
Partition check:
 sda: sda1 sda2 sda3

If I issue the command df only 2GB of space is reported.
Where is the others GBs?

Thanks
