Failing to read drive: "Very big device. Trying to use READCAPACITY(16)"

Dear kernel people,
We are trying to access the harddrive of a decomissioned laptop.
It's a Western Digital Scorpio Blue 320Gb SATA drive (WD3200BEVT¹,
When we attach it via USB, however, the kernel fails to read its
size and assumes it's 2**32 blocks long (2 TiB):
kernel: [ 2466.318829] scsi 9:0:0:0: Direct-Access PQ: 0 ANSI: 2 CCS
kernel: [ 2466.319359] sd 9:0:0:0: Attached scsi generic sg9 type 0
kernel: [ 2466.323641] sd 9:0:0:0: [sdh] Very big device. Trying to use READ CAPACITY(16).
kernel: [ 2466.325387] sd 9:0:0:0: [sdh] Using 0xffffffff as device size

kernel: [ 2466.326060] sd 9:0:0:0: [sdh] Write Protect is off
kernel: [ 2466.326063] sd 9:0:0:0: [sdh] Mode Sense: 00 38 00 00
kernel: [ 2466.326066] sd 9:0:0:0: [sdh] Assuming drive cache: write through
kernel: [ 2466.333816] sdh: unknown partition table
kernel: [ 2466.360579] sd 9:0:0:0: [sdh] Attached SCSI disk
If we attach it directly to the SATA bus, it is not detected.
Is there anything we can do, or is this drive simply lost?

who's general failure, and why's he reading my disk?
