Hi,

I am in the process of trying to recover some data from a hard drive melt d=
own. =

The drive is a SATA Seagate Barracuda 7200.7. When pursuing this I have fou=
nd =

that the drive actually has a serial (UART) terminal interface which can be =

accessed through the jumper pins without even connecting anything to the (S=
)ATA =

interface. This goes for drives with both the (P)ATA and SATA interface. =


The terminal interface has a ton of commands that are primarily used at =

manufacturing and testing. There exists software that can read data from th=
e =

drive using the terminal interface (as part of a recover process) and I ass=
ume =

it can write data to it also.

Even though this might only work on old seagate drives, it is an interestin=
g =

idea to have access to (almost) unlimited storage space for a small PIC thr=
ough =

a simple and relatively slow RX/TX serial interface.

Has this been done with a PIC or any small micro before?
