Old issue with Sony Ericsson W800i reporting wrong Memory Stick capacity
seems to be solved - with new firmware R1AA007 it reports something closer
to 512 MB:

$ dmesg
...
usb-storage: device found at 5
usb-storage: waiting for device to settle before scanning
   Vendor: Sony Eri  Model: Memory Stick      Rev: 0000
   Type:   Direct-Access                      ANSI SCSI revision: 00
SCSI device sda: 960512 512-byte hdwr sectors (492 MB)
sda: Write Protect is off
sda: Mode Sense: 00 6a 00 00
sda: assuming drive cache: write through
SCSI device sda: 960512 512-byte hdwr sectors (492 MB)
sda: Write Protect is off
sda: Mode Sense: 00 6a 00 00
sda: assuming drive cache: write through
  sda:
sd 10:0:0:0: Attached scsi removable disk sda
usb-storage: device scan complete
...

Just for record - this probably applies to D750i, too.
