Hey Jaclaz!

 

 If someone still has problem with failing drives and need a serial-to-TTL i found this little puppy!

This would have saved me some cash at least.

It seems like that the regular Usb-to-RS232 (serial) is at first TTL and then converted to serial signals with the Max213.

By solder some wires to these tiny tiny pins, you can get the TTL-signal before converted.

Hacking the Usb-to-serial is here: http://yd0nxx.wordpr...serial-adapter/

Datasheet for the Max213 is here: http://www.alldatash...MAX213ECAI.html

This is for the Profilic Usb-to-serial-adapter, but it is maybe the same for different manufacturer, or at least same concept?

If possible, you maybe can move this to the beginning of the thread?

I wouldn't be so sure/I don't know. :unsure:

 

The point is that the TTL level in the given link is given as 5V TTL (seemingly the "wrong" one or TTL/CMOS), you possibly missed the READ-ME-FIRST:

http://www.msfn.org/...-read-me-first/

 

particularly point 6 and the visual representation (original page is down now, but till viewable through Wayback Machine):

https://web.archive...._threshold.html

AND point 10.

 

This might also possibly clear the matter:

http://www.msfn.org/...72004/?p=972251

the difference between SHOUTED ENGLISH and whispered English easier to grasp ;).

 

So, while it is well possible that the Author of the "hacking adapter" is "wrong" :w00t: (and the actual TTL level between the Prolific chip and the Max213 is the "right" one at 3.3V) I would need some definite report of this hack (or of a similar one) working with one of these stupid 7200.11's before being convinced that it could represent a viable solution.

Hello Everyone,

 

Apparently my drive seems also bricked too. I am getting "Incorrect Function" when I try to initialize the disk via Disk manager on windows 2008.

 

Manufacturer : Seagate

Model : ST3500320AS

Barracuda 500 GB 7200.11

 

I ordered the necessary cable and going to follow the process soon,

 

Can you please check the screenshot, is it the reason when LBA0 happen to a disk... I beleive its not BSY because I am able to see it on windows...

 

Thanks,

 

M.G.

Yep, but do check also how the BIOS sees it.

A BSY disk won't be detected at all.

A LBA0 will be detected but with 0 size.

I've just managed to recover my Stupid Barracuda 7200.11 HDD.  I used the USB to RS232 TTL converter I bought from the following ebay link.

 

http://www.ebay.com/...=STRK:MEBIDX:IT

 

It costs only US$1.72, but took about 7 weeks to be shipped from Hong Kong to Singapore.

 

The cable works perfectly when I did the loop test by shorting the green and white color cable.

 

To connect to the HDD, I need to remove the black casing at the end of the cables, and covered it with insulative tapes individually.  After that I followed the instructions and connect it to the HDD.  Initially, it cannot communicate -> no respond after entering CTRL-z at the hyperterminal.  Then, I swapped the green and white cable, also did not respond.  I noticed the metal end of the cable could be too loose to have a good contact with the HDD pins.  I then used a plier to make the metal sleeve narrower to ensure good contact when plug in.  After this, it responded when I type CTRL-z.

 

I used the Avico procedures but without the optional codes initially.  After the last instruction (m0,2,2,0,0,0,0,22), there was no message return after waiting for more than 10 minutes. 

 

I then, power off the HDD. and repeat the procedures from the beginning (including removing the screws and re-inserting an anti-static plastic in between the PCB and heads connector).  This time, I used the optional part and after typing the last instruction, it immediately return the Max Wr Retires = 00, Max Rd .......... message.  Great !

 

I am now able to get back all the data and will update the Firmware.

 

Thanks to all the contributors in this forum !

Hey guys!

 

After attempting to fix my drive, it shows up in bios and windows with the correct capacity. Unfortunately it doesn't respond when I try to open up my drive in Windows. It also takes about 15 min to boot up windows. When I doubleclick my computer, it doesn't respond unless I detach my drive from the computer. I attached the hd internally.

 

ST3750330AS is my hd with firmware SD35

 

Windows 8.1 x64

 

Does anybody have any suggestions as what to do next?
