CylonWolf Posted December 23, 2013 Share Posted December 23, 2013 Hi, I apologize in advance if Im asking something thats been posted somewhere, but Ive not seen anything regarding it so far.I have my adapter setup, Ive did the loopback test to make sure everything is working with it, so basically ready to start the actual procedure. The adapter is USB powered (its this one: http://www.ebay.com/itm/280748167812?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649), so no need to hook it up to the power supply. What Im particularly nervous about is powering the HDD. My plan was to use the same power supply that is in my terminal computer...power off the computer, plug everything in, and power back on before proceeding... but if I need to power cycle the drive at some point, this could be an issue. Is it much better to use a stand alone power supply to power the HDD only? Link to comment Share on other sites More sharing options...
jaclaz Posted December 23, 2013 Share Posted December 23, 2013 Is it much better to use a stand alone power supply to power the HDD only?Yes and no. The advantage of having ALL the devices involved (the PC, the converter and the disk) powered by the same PSU is that you won't have the need to ground everything together in order to avoid possible ground loops (and consequent gibberish on the terminal).Having a separate power supply implies the need for accurate grounding, but it is easier to remove power off the disk.With a single PSU, you simply pull off the disk power connector, then switch off the PC and reboot and re-connected it (and this is more or less likely to take the suggested 60 seconds).Please consider also (see the recommended guide by CarterinCanada: http://www.mapleleafmountain.com/seagatebrick.html ) how the actual powering off of the disk drive may be needed or may be needed not. jaclaz Link to comment Share on other sites More sharing options...
Milos87 Posted December 23, 2013 Share Posted December 23, 2013 Hello, i menage to start communication with HDD(with controler 232) and get to spin up command and when i supposed to pull out paper card and tighten screws one screw nearest to hdd motor moved about 1/10 mm and touched one of power lines and HDD is dead ( Unfortunately now i need to send HDD to get all of my data back to another HDD. Thanks for help guys!! Link to comment Share on other sites More sharing options...
jaclaz Posted December 24, 2013 Share Posted December 24, 2013 one screw nearest to hdd motor moved about 1/10 mm and touched one of power lines NO .1/10 of a mm is a 1/10 of a mm, there are NO "power lines" within 0.1 mm from any screw on the PCB of a ST3100034as:http://cdn.shopify.com/s/files/1/0207/3304/products/ST3100034AS_FW_HP13_100466824_REV_C_PCB_1024x1024.jpeg?v=1378998992and at least last time I checked screws did not move by themselves.I am sorry for your misadventure , but evidently you did something else and the *whatever* you did caused *something* to move more than 1/10 mm.jaclaz Link to comment Share on other sites More sharing options...
Milos87 Posted December 24, 2013 Share Posted December 24, 2013 I followed line and it seams that screw touched signal line to RX pin and that caused spark, and hdd is dead, that happened when i tried to tighten the screw, and screw fell on that side where is signal line and the end :( Link to comment Share on other sites More sharing options...

jaclaz Posted December 24, 2013 Share Posted December 24, 2013 You are likely having BOTH a connection issue AND a grounding issue. Which EXACT converter are you using?How EXACTLY are you powering the converter?How EXACTLY are you powering the hard disk?Does the loopback test work OK?At which speed settings did you set HyperTerminal?Should you have failed to read the read-me-first and FGA's, NOW is like the right time to do it:http://www.msfn.org/board/topic/143880-seagate-barracuda-720011-read-me-first/http://www.msfn.org/board/topic/147532-fga-for-the-seagate-720011-drives/jaclaz Link to comment Share on other sites More sharing options...
Beezgr Posted December 25, 2013 Share Posted December 25, 2013 (edited) Thanks Jac for the fast reply !!!!i have read those links ofc !!! at the second FGA i am at 4 Ctrl Z doesn't work... !!! lolloop test is working as it should be now about converter i use a USB one bought from ebay i think converter draw power from usb and about hdd i use an external power source plugged directly to hdd.sata molex.speed at terminal you talk about 38400 right ? or somethiung else ?thanks !!this is the controler btwhttp://www.ebay.co.uk/itm/STM3500320AS-ST3500320AS-HDD-Repair-Tools/221309522581?_trksid=p2045573.m2042&_trkparms=aid%3D111000%26algo%3DREC.CURRENT%26ao%3D1%26asc%3D27%26meid%3D3643536863362203267%26pid%3D100033%26prg%3D1011%26rk%3D1%26rkt%3D4%26sd%3D280748167812%26 Edited December 25, 2013 by Beezgr Link to comment Share on other sites More sharing options...

Hopefully itll finish copying all of the files before the drive experiences anymore issues Very exciting to see what files I had forgotten about that are on this drive. Thanks again everyone involved in putting this guide together! Link to comment Share on other sites More sharing options...
mathemaddicts Posted January 5, 2014 Share Posted January 5, 2014 Hello all,First, thank you for compiling such a complete thread on this topic. My wife is a photographer and had a 7200.11 bricked right now (and I think) because of this issue. None of our PCs will recognize the disk (in BIOS).I am a complete layperson when it comes to doing anything with electronics (other than slapping together a desktop). To be honest, I am also quite short on time to do such a repair. Does anyone on this board, who has done this job before and has the proper tools, offer their services to others to "unbrick" these drives so we may get our data off?I am sorry if this has been asked before, but I didn't see it in the Read This sticky or about 30 pages of this thread.Thanks,Roy Link to comment Share on other sites More sharing options...
Casalla1 Posted January 5, 2014 Share Posted January 5, 2014 Hi!I need some help, too.at first, sorry for my bad english. Im from Germany, if you want to know.Problem: Hyperterminal under Win XP is very slow, and most of time it does nothing, or sends errors to screen, unfortunality it looks like egypt hyroglyphes.In the beginning, it needs al lot of STRG-Z's to get the first prompt, where i can Type my "/2", if i had doen this, and pressed ENTER, the cursor only goes to beginning of line, and then... nothing. eventually there comes a lot of Error, i cant read it really, cause it looks senseless.Equipment:this adapter from Artekit/italy: http://www.artekit.eu/products/accessories/ak-rs232/Backlooptest OK.Powersource for the TTL-Adapter: at first USB-Charging Supply (HTC MobilePhone) with USB-2-Pole-Cable (Checked with Multimeter: 4,5-5V),at second 1 CR2023-Battery (3V), effektivly circa 2,7VPC: Pentium4, 1GB, Windows SP 32-bitPowersource for the HDD: the extern-Power-Supply from my HDD-Adapter SATA-to-USBand, of course, the seagate HDD (if got 2 of them, but only 1 is important with Data)If i let the Paper away from motor-contacts, the motor runs, and i got the wished errormessage.Can anyone tell me, what i did wrong?I am afraid about every help, tipp and trick!Thanks, and greetings,Casalla Link to comment Share on other sites More sharing options...

Thanks, RoyActually such kind of "service offers" (and consequently - though indirectly - corresponding requests) are conflicting with Rule #13: http://www.msfn.org/board/index.php?app=forums&module=extras§ion=boardrules You haven't got a friend more familiar with electronics? Or have in the neighbourhood a shop that repairs cellular phones (who normally already has the converter and can follow the guide easily)? jaclaz Link to comment Share on other sites More sharing options...

Casalla1 Posted January 5, 2014 Share Posted January 5, 2014 Hi,THX for your fast Answer!Jeah, I had read this Pages, and a lot more, but sometimes its so much reading in a "strange language", so the one or other goes away of my simple sense ;-)Ok, if I understand specially this point #7, I tell it in my simple words:The Pin "Grnd" at HDD must Conected with one of the black cables from the HDD-Power-Supply (in my Case the external HDD Power Supply i use),so I got 3 Points of the construction are connected together."Grnd Converter">>>>"Grnd HDD">>>>"Black Cable Power supply" is the shematic?Sorry for my explicit writing and questioning, i want to cut off any Errors and Fails...I can't see anywhere on Pictures a connection between this contacts, neither at Mapleleaf, nor here, so i wonder, but, if i understand it right now, i can comprehend this necessity...So i will test it.I tell my success (or fail) here...Casalla Link to comment Share on other sites More sharing options...
