Hard disk: WD Scopio Blue - 160 GB - WD1600BEVT-22ZCT0
 * Form Factor 2.5"
 * Operating temperature 0 &mdash; 60 ⁰C
 * Spindle speed 5400 rpm (90 rotations/second)
 * Serial ATA 3 Gbit/s
 * Buffer size 8 MB
 * Non-Recoverable Errors 1 per 10^14
 * JTAG
 * LVTTL 3.3V Asynchronous communication port 115200 8N1

Design layout:
 * Cache DRAM 8 MB
 * Microcontroller, ARMv7 88i6745
 * Three-phase spindle motor controller L7206

The LVTTL asynchronous port is located above "R36" on the top side. In order from R36 towards the top the connections are: unknown, TX from hdd, RX to hdd, unknown. Console is enable by connecting a resistor 4k7 between test point P1 (+3.3V) and test point E6.

Communications parameters are 115200 8N1. The console when activated supports three commands:
 * r <32-bit address> ; read 16-bit from address
 * w <32-bit address> <16-bit data> ; write to address
 * j <32-bit address> ; Jump or call code
 * h ; Halt?
 * Supports X-modem

JTAG is located on the top side PCB, opposite connection pad row of the "CON1" text. Counting from the marking "37" and left: GND, GND, GND, GND, GND, GND, GND, GND, RST, TDI, TMS, CLK IN, CLK OUT, TDO, E35, nc, GND, nc, nc.

Boot strap:
 * Flash start at 0x0000 0000 translates to physical address 0xFFF0 0000
 * Flash size is 0x30000
 * System image header ID: 0x5A 04 00 00

Connection with a 4.7k resistor between E61 and GND. Makes the drive on powering on to perform a RAM test.
