Gradius2-

Let me start off and personally thank you for the work you have done in putting together this guide for us all. I haven't performed the fix yet, but am planning to very soon.

I am wondering if it would be at all possible to give a part list with links to a site where you purchased your materials. I already saw your RS232 link but I want to make sure I get the right connectors, wires, battery holders, etc. I hope I am not being to forward.

Also I'd like to make a suggestion for you to set up some way that others, including myself, can possibly send a donation as a sign of appreciation for what you have done. If it wasn't for this guide, many people might be forced to pay hundreds of dollars in data recovery fees. .. just a thought.

I would also like to thank Gradius2 for the tenacity, persistence, and willingness to share his work with the rest of us. I too would like to thank with more than words.

It would be nice if someone would start making these cables and selling them on eBay maybe...

Hey guys! :hello:

Trying to find components here in Sweden to build me my own interface. Since Seagate are giving us the silent treatment I don't have to much hope in them saving my data (atleast not within reasonable time).

The problem is that I'm having a hard time finding the RS232 to TTL converter. I have emailed the biggest electronic component store and asked, but they are probably sleeping at the moment. =) SO thought I'd check with you guys if you think that any of the pasted names links below could do it?

FT232BL USB - seriellt if LQFP32

https://www1.elfa.se/data1/wwwroot/webroot/...TA/07320658.pdf

FT232RL USB - seriellt if SSOP28

https://www1.elfa.se/data1/wwwroot/webroot/...TA/07320659.pdf

FT232RQ USB - seriellt if QFN32

https://www1.elfa.se/data1/wwwroot/webroot/...TA/07320659.pdf

FT2232D 2x combined FT232/245 LQFP48

https://www1.elfa.se/data1/wwwroot/webroot/...TA/07320666.pdf

Cheers!

The problem is that none there is in clear text RS232 to TTL. But maybe TTL is referred to as something else also?

Guys I'm new here.. I've got 10 DiamondMax22 1TB drives with MX15 in a RAID-6 and I'm hoping when I next power cycle them they come back up..

I just thought this might come in handy. It's a USB->3.3v TTL converter used to program the Parallax Propeller chip. It has a standard FTDI USB interface on it and by clipping 2 pins off the TTL connector it will plug right into the back of the seagate drives perfectly.

http://www.parallax.com/Store/Microcontrol...98/Default.aspx

I know Parallax have distributors across the globe, so I thought those of you looking for USB->TTL converts might find this handy.

I'm taking one home with me just in case my drives fail when I shut the machine down to firmware upgrade them (provided Seagate actually gets a fix out anyway).

Hope this might help someone.

Cheers..

<edit> Oh friggin 'eck. I've just read the Seagate forums. I'm not that BradC!

Hey all,

I have a "friend" from these boards coming over tomorrow with a bricked drive. I will get him to film the process and I'll post a video. It should make things much clearer to everyone as to the "power on/off", when and how long etc.

If you are unsure of what you are doing, STOP NOW and wait. It will be worth it.

Check back around 7PM MST Wednesday Jan 21st.

Thanks,

Fatlip

Thanks fatlip. will eagerly await the video. Right now I'm understandably confused by the 5V and 3.3V and which ones I should be doing etc etc. On top of that finding that RS232 chippy thingy is harder than I thought (buying from eBay is not an option for me I live on the other side of the planet). If possible can we get a clear footage on removing the connector since that part seemed to be a delicate part of the process.

Thanks again, you the man, man!

Nobody has an idea what will help against my problem described in #56 ? I can't imagine it's a hardware fault.

It just won't regenerate the partition successfully...

Connect the HD on terminal, you should be able to see which error is (if CC or not).

Gradius

I don't get the CC message, but the method of "unbricking" 0LBA-drives does not work. Seems like I have to wait for any news or for an answer from Seagate.

Umm.... :huh:

I connected my rs232 board's TX to Seagate's TX [ oo*o ] [ ......] [...................]

and rs232's RX to Seagate's RX [ooo*] [ ......] [...................]

Did I wrong or Did I disunderstand?

Anyway It worked. I succeed in solving a "Not Detecting" problem. :o

Thanks.

Keep in mind TX and RX from Seagate are exactly like that, but on Seagate side.

Connect it this way:

PC (TX) > RX on Seagate

PC (RX) > TX on Seagate

The wires was inverted to me and I didn't get nothing, so I just reverted and finally got a terminal answer.

Look at my post here:

This is all you need and it will take the confusion out of the voltage issue.

You didn't do anything like sticking your HD in the freezer or anything extreme did you? Some people went to desperate measures to figure out what was up with their drive. Sadly, one suggestion out there is to stick it in the freezer.

I seriously think you have a regular failed drive. The 1-2% normal failure rate.

Thanks for sharing this information! Can anyone confirm that this will work for hooking up drives to a terminal?

The guides and help from Gradius2, pichi and fatlip are great, I'm willing to give it a try as well but I want to be sure to order the right converter.

barakaspeed,

I'll update the guide (once more) with links for the materials. So far, you'll spend $20 or less in all them.

About donation, I created this link

Does this look like it would work?

http://alldav.com/index.php?main_page=prod...d6ba656f1d26c58

Looks like only $4 in US shipped.

Yes, it will. I used a more expensive one, yet more simple:

http://www.sparkfun.com/commerce/product_i...products_id=449

Includes full pics and schematic.

Gradius

I would also like to thank Gradius2 for the tenacity, persistence, and willingness to share his work with the rest of us. I too would like to thank with more than words.

They sell jumpers (wires), but since I'm on Chile and I couldn't wait too long importing them, I just made them myself. :blushing:

http://www.hobbyengineering.com/H2362.html

You only need 4 (four), but they sell 10 (minimum). Includes 20 headers too.

FT232BL will works just fine, the problem it looks like IC only, and not mounted (ready to use).

Will I be able to recover my data using the method stated in Post#1? I think my drive is in BSY mode at the moment.
