So you mean if this solves the problem of not spinning up the disks, then I can use the disks without problems like forever? Or just until I recovered everything to new Drives? Quote Link to comment
Mor9oth Posted October 10, 2020 Author Share Posted October 10, 2020 I just removed the PCB. So one of the bigger diodes in the circles are the protection diodes, right? Quote Link to comment

Yes, trace the diode which connect the RED wire at power plug side. Bottom left one not relate. Any burn-out found ? Edited October 10, 2020 by Vr2Io Quote Link to comment

Yes too. Only one was target, but I can't confirm which one by the PIC, need multimeter. Don't try guess. Edited October 10, 2020 by Vr2Io Quote Link to comment

Sorry, what do you mean? Which Red wire? On the picture is no wire. Do you mean the line? so this one? (Circled) Quote Link to comment
Vr2Io Posted October 10, 2020 Share Posted October 10, 2020 (edited) I can't tell you which one or fault identify, sorry this need some electronic skill and know how to use multimeter to troubleshoot. Those component/circuit may contain fuse too. Pls don't do anything if you can't confirm. Some info.

In OL Mode the obove D47 rings up. This could be the one to remove. Quote Link to comment

If I need to buy new drives than it hurts but it is ok. All my settings of dockers, shares etc. are important. And of course the Data on the shares. Quote Link to comment

You can easily do more harm than good by attempting this yourself. Quote Link to comment

Pls test on molex power plug and not on component as previous two PIC show, if both readings are OL, then you should get professional service for get back your data.

Typically they would copy the files to a new drive, but if you tell them you need bit level cloning for parity recovery they would attempt that if asked, obviously that would require the same size drive.

Mor9oth Posted October 11, 2020 Author Share Posted October 11, 2020 So after some sleep and checking my files on my PC I came to the conclusion that the best way is to try first get my Drives replaces by RMA. But this rises the question is returning of shucked drives even possible? Maybe voided warranty because of opening the cases? I bought them on Amazon and did not keep the cases since I never thought this could happen ... Does anybody have experience in getting shucked Drives without cases replaced/refund? (byte my bits did, but he is a Youtuber). Quote Note. If you go RMA disk route and OK for lost all data, then could forget the multimeter. After that, contact SS to got a good blackplane, that's all. Today I also realized that the other backplate from the second cage is also not working - or the HBA-Card, or the Data cables aren't working. Symptoms: The LEDs are on, but the old 1 TB HDD (also tested a 500 GB one) is not been shown up in Bios and LSI list (boot sequence). But when I plug it directly over SATA, then I have the drive in the Bios and Unraid. 👉 So I guess the second backplate also died but LEDs still working. Right? Or something wrong with cables (I switched all I have, nothing changed), or the HBA itself (doesn't look like this, since showing up in Bios). But if 2 of 2 backplates and 4 of 4 Drives died - I really want to make sure that if I replace them (backplates and drives) then everything is set up correctly. I had it connected the following way: Power goes from PCI-E 8 pin connector (Power supply), split by 6 PIN Adapter (Y-cable, included to the SilverStone CS381 Case) to each Cage. The Cage has the 6 PIN female port, so this seems correct to me. Or is here a Problem? Can I reuse it that way if I got replaced the backplates and the Drives? Data: Mini SAS cable (SFF-8643 to SFF-8087) from the Cage to the HBA. This seems 100% correct to me. I really hope someone can help me with this - seems important since a lot of hardware died and I want to make sure to refuse it. Alternatively I just don't use hot swap anymore and just go SATA. But this would be sad. Thank you for your help! Quote Link to comment

Yes, if CS381 out if warranty. But I also agree if root cause can't identify, then reuse it will be danger even you got good blackplane replacement, same problem can happen again.

So I can remove the safety diode, otherwise I can only throw away the hard drives. That would at least be a chance for the data. Quote Link to comment

If you won't get 3rd party maintenance service then seems remain DIY path only, but best get help from person which have some electronic knowledge, if too many unknow then almost no successful chance. If DIY, pls try on parity disk, and provide two resistance measurement (reveser tip for the 2nd reading) across the suspect TVS diode. Edited October 12, 2020 by Vr2Io Quote Link to comment
Mor9oth Posted October 12, 2020 Author Share Posted October 12, 2020 I don't want to do it by myself. But I guess Data recovery Center are way too expensive, so I think a small er PC Doctor with electronic knowledge should be able to find out if the drives can be saved/repaired. And then he can maybe remove the diode. Quote Link to comment
Mor9oth Posted October 12, 2020 Author Share Posted October 12, 2020 What I tried by myself: Tested with multimeter the drives connected with a SATA to Molex Adapter. All crossed (Alternating red and black cable with the sensors) Red/Black measurements shows OL; all Black/Black gives me ring up. What does this mean when I go to a PC Doctor? Quote Link to comment

Alright, I guess I have to restart it from scratch. At least with new drives. But how does it work in my current Unraid? How do I set up a new Array in Unraid? At the moment my old drives are still shown up as "disabled/missing". Choosing a different Drive gives me the message "wrong" What is the best way to replace the old setting? This is how it currently looks like: Quote Link to comment
