confused999 Posted March 28, 2009 Share Posted March 28, 2009 I've been having problems trying to talk with my hard drive through terminal software. I've tried both PuTTY and HyperTerminal, but neither seem to work. I verified that my USB to UART adapater was working fine by doing a loopback test and it passed, but when I hook it up to the hard drive, nothing comes up when i push CTRL+z. Is it necessary to connect the ground cable from the board to the hard drive as well? Might have been my problem when I was trying it. I'm using this board btw http://alldav.com/index.php?main_page=prod...;products_id=21You need connect GND too (pin3).I think that the board is good.I too am having having the same problem and pin 3 of the serial connector is TX Data. Why would one ground that pin to electrical ground of the power source?? Link to comment Share on other sites More sharing options...

If so then one has to connector a jumper wire from the GND lead from the battery to pin3 on the jumper block??

Was able to revive the hard drive and then flash it. Thanks for the help. Edited March 29, 2009 by confused999 Link to comment Share on other sites More sharing options...
Puppetnation Posted March 30, 2009 Share Posted March 30, 2009 (edited) Hello everybody!Thanks Gradius2 for putting vital info on resuscitating hard-drives, your contribution is very very precious!I'm so excited: tomorrow I'll get the necessary gear and will fix my 30-days old "locked" 1TB drive plenty of data.This condition makes my stomach burning... I think restoring access to personal data has no price...At Seagate they say "mine it's not affected"... it's easy to act like this... they simply offer a drive replacement...thanks so muchI'll let you know!Update: haven't found the serial interface on shops, ordered on eBay and waiting for the postman to come, maybe this week I'll be on the job!

zatang2009 Posted March 30, 2009 Share Posted March 30, 2009 Hi, Thanks for all the info but I am stuck with a problem. I have this Nokia CA-42 clone. There are 3 wires in itBlack, white and blueBlack is GND as it is mentioned on the IC. Also, i tested it through a Voltmeter and I am getting above 3.3V on both White and Blue, i.e., when connecting the Negative of Voltmeter to black and Positive to White or BlueThen its saying connected to terminal, but i am not able to type anything in it. When trying different USB ports, i got it typing for a while but it was only momentary. Now what to do ?How to make it type in Terminal Window ?? Also i am not getting any random characters when i joined TX and RX or (TX + GND) or (RX + GND). Now what to do ? Link to comment Share on other sites More sharing options...
BlackFyre Posted March 31, 2009 Share Posted March 31, 2009 Hi Guys, I'm currently trying to repair my Seagate 1TB harddrive, and purchased a CA-42 cable off e-bay.M/N: WACAS07The cable when opened up has Red, Black, Green and White.Has anyone else used this cable, the connectors are blue and the cable itself is black.Just wondering which color is which.Thanks Guys Link to comment Share on other sites More sharing options...
MikeT31 Posted March 31, 2009 Share Posted March 31, 2009 I am so glad I found this forum. This evening I experienced the BSY error. IMHO I am competent enough to attempt this fix , but I want to describe my problem to you guys before I try. Maybe if I am missing something you can warn me. My drive is ST31000340AS bought last August. Label claims it has the SD15 firmware. The whole drive is encrypted using TrueCrypt. There are three partitions. The drive does not matter to me, I just want my data. Will the partitions and encryption cause complications for this recovery method?One more issue. I experienced power failure this evening. On my first restart the computer worked fine for an hour and I shut down normally. On my next power up it failed and was not recognized in BIOS. I already tried the drive on my second computer and it was not recognized in BIOS. Still, my problem could be another issue not related to the BSY error. I would appreciate any advice you could give me. Link to comment Share on other sites More sharing options...
circuit Posted March 31, 2009 Share Posted March 31, 2009 I have tried and tried to get this to work ...when i connect everything all i get in hypertermis a black arrow pointing to the right ..each time i hit ctrl z i get the blackarrow to the rightif i unhook the wire ctrl z does nothing if i do a loopback test i get my text back ....

bloodraveb27 Posted March 31, 2009 Share Posted March 31, 2009 (edited) my story my pc was ok until the close 2 days ago after open pc windows never start and when i unpick seagate it opened as normal...it's saying " Drive is not affected. No action required." on the https://apps1.seagate.com/rms_af_srl_chk/ but this happened and i found this forum...i am going to find a nokia CA-42 cable and if i can i will post the result...

This recovery method normally doesn't touch the "User Data" of the hdd.This method repair the "Service Area" of the hdd, a hidden area of the aluminium plates. This area is out of the disk capacity.

brother Posted April 1, 2009 Share Posted April 1, 2009 HiI have a Maxtor Diamondmax 22 STM3500320AS 500 Go wich seems to have the BSY error. I bought an RS232/TTL adapter that I wait for and also the other stuff. Since my english is not 100% sure, I don't want to miss something before I start to unblock the HDD. When Gradius2 says "connect the power supply to Hard drive circuit board", is it the sata power ? Thanks Link to comment Share on other sites More sharing options...
