Force Seagate 2.5" SSHD ST1000LM014 to SATA1

[davidcie]

(Posting one reply after another as I have not found a way to edit posts.)

Update: switched my bridge to 3.3V by lifting one of the chip's pins and connecting it to 3.3V as per PL2303 datasheet. The board passes the loopback test just fine, but is now unable to communicate with the HDD at all (no output via PuTTY regardless of baud rate). I'll try to get an oscilloscope to see what sort of output levels I should be expecting, and work from there.

Btw, thank you for all your help so far, the response has been fantastic and really appreciated. Would not have gotten very far without you!

Gentlemen, just wanted to update you on the progress so far. I've managed to borrow an oscilloscope and noticed that the HDD does not pull its Tx line to 0V when communicating with the world. Instead it uses ~1.9-2.0V for "1" and ~0.6-0.8V for "0". Using PL-2303HXA datasheet I was able to tweak its Serial I/O voltage so that the built-in Schmitt trigger interprets these levels correctly. It turns out that 3.8-4.0V applied to the VDD_325 pin works a treat. Because noise on the HDD's Tx line increases a lot with voltage, I sticked to 3.8V, which boils down to Schmitt thresholds of around 1.25V and 1.9V (negative-going and positive-going, respectively). (Sharing these so that future generations may tweak their interfaces accordingly.)

I can also confirm that the correct interface values for this drive are: 38400 speed, 8 data bits, no parity, one stop bit, no flow control.

The second good news is that - judging by the prompt - the drive is indeed an F3 generation.

Off to trying some commands then

(I'm not much of an HDD specialist so please bear with me if I post something irrelevant / outright silly. Also not sure if I should be posting larger data dumps here; if not please let me know.)

From what I've understood so far the drive's controller and its firmware may be something slightly different to the drive itself. Hence I should probably concentrate on the controller area. Follwing on that conclusion, I've extracted controller register dump (^I command). Can you please have a look and check if anything you see makes sense? All it tells me so far is that the controller is probably a LuxorPlus rev 0203... which doesn't tell me much but perhaps will ring a bell to any of you if it is used in other drives.

Assuming max speed is stored in one of these memory locations - would (permanently) changing the drive's advertised speed be as simple as writing the right value to the right register, or are these re-populated upon power-up?

Code:

LuxorPlus Rev: 0203; No Host; SpdLimit: 6.0GbMax;  SSC: Yes; LED: No; StagSpinByp: Yes;

It seems that the above registers do change dynamically, and are not configuration information... Connected the drive to a 3.0Gbps controller and many values did change. So need to keep looking.

I have found a few interesting batch files in the SM15 firmware file: scripts/ata/featurecontrol.ss and scripts/ata/speedcontrol.ss. Thought I might be able to run them via level 6 commands, but B<x>, D<x> and E<x> are not available (my drive responds with "Invalid Diag Cmd") Do you know how I might be able to run these and/or "unpack" the firmware archive to check what's inside? It should be possible: I've found reference to a scripts/ata/thumbs.db file in the firmware archive, which - incredibly enough - could be a by-product of someone using Windows to pack it in the first place!

I think this is as far as I can get today without your input and helpful minds

also worth mentioning that incompatability may go deeper than simply the Gbit/s speed limit, and be something in the actual newer system that is NEVER going to work..

From many other reports with other drives I'm pretty sure "simply" forcing the drive to 1.5Gbps should be sufficient and make them both happily work together. Even if the worst comes to worst, I will hopefully have learned a little and entertained you with my incredible ignorance in the process

A little update on what I've written above: of course the "firmware" with script files turned out not to be firmware; these are rather "CAB" files (not real CAB, this is some custom file format) used by the SeaTools Express utility that is on the default firmware update CD. The real firmware sits in the KHTSM152D LOD file (uploaded to Speedyshare in case you want to have a look). The firmware itself does not seem to be encrypted, and I can see some interesting strings inside:

• SATA feature enable selected
• 6Gb Max Speed lowered to 3Gb for Intel bug (not the 1.5Gbps I'm looking for but hey it's a start)
• Fast IO Cmd, F[NumRevs],[Attrib1],[Attrib2],[Attrib3]
• Display Hardware Jumper Setting, j[HardwareJumperSelect]
• Reset drive customer settings, SHIP,[ParmValue]

Would love to get info on these, not very good with disassembly

Hi,
Here are all the strings I found so far. It may help you in the terminal..

Hi,

nice that he can connect to the Harddrive.
I've the same Harddisk bit I didnt get any connection to the Terminal.

My Connection is the same like davidcie
PCB-side up: [EMPTY GNDcable RXcable TXcable] [.......] [..................].

Baud: 38400
data bits: 8
parity: none
stop bit: 1
flow control: none

but I dont recieve any feedback from the Terminal.
The Cursor an Hyperterminal is just blinking, in putty just a green cursor.

Any ideas?

Best regards
Fabian

[davidcie]

If you cannot see anything on the terminal first swap the RX/TX cables, they might be labelled incorrectly on your serial interface. Second, make sure your serial interface is able to work with lower voltages as described above.
