yes this is a fairly old WD

original was

Device Model: WDC WD1600JS-22MHB0
Firmware Version: 02.01C03
User Capacity: 160,041,885,696 bytes


they replaced with

Device Model: WDC WD1600JS-75NCB2
Firmware Version: 10.02E03
User Capacity: 160,000,000,000 bytes

which looks quite strange as it looks like something got lopped off somehow. I 
didn't think bad blocking/sectoring was done any more. Anyhow they've removed 
this disk and are considering options (at least I hope they are).
