rmilyard Posted December 4, 2018 Share Posted December 4, 2018 Question for all. I have used these 8tb external Seagate drives in the past that I have shucked from case. No issues. So black friend I purchased 3 from Newegg and 1 from Amazon. All of them now have Reallocated sector count! In the past didn't get this. So I put them all back in cases and tested them with SeaTools and ran the Fix All - Long and they all pass. Is Seagate doing something to these drives now? Quote Link to comment

I was wondering if they did something with the controller board now to maybe cause it to skip these or something. Quote Link to comment
rmilyard Posted December 10, 2018 Share Posted December 10, 2018 Ok so it has to be something Seagate is doing. I picked up 8 of these new. All 8 have failed with same issues. No way would 8 fail. I have used them in the past with no issues but now can't get one to work. Remove them from UnRAID put back in case and run Seagate tools and all test fine. Quote Link to comment
BRiT Posted December 10, 2018 Share Posted December 10, 2018 Maybe they have the reset-pin issue? Quote Link to comment

rmilyard Posted December 10, 2018 Share Posted December 10, 2018 Here is one I have right now. New drive. milyard-tower-smart-20181210-0820.zip Quote Link to comment
JorgeB Posted December 10, 2018 Share Posted December 10, 2018 Looks to me just like a normal failing drive, don't see how it can be related to being shucked. Quote Link to comment
rmilyard Posted December 10, 2018 Share Posted December 10, 2018 Here is one more that had 9000hrs on it. All the others I have returned. milyard-tower-smart-20181210-0838.zip Quote Link to comment

Just switched to a WD Red and zero errors in same port. So don't think it's the controller or power. Quote Link to comment

Then bad luck, I'm sure Seagate could cause bad sectors on a disk if they wanted to, I have a program that can create pending sectors on many disks, but for me it doesn't make any sense they doing that on purpose, at least not without a big warning on the disks "using this disk outside the USB enclosure will damage it" or most users would just think they got a bad disk, and that's not good for the brand.

Hi! Is there more info on what exactly is TGMR? I have a 8TB Seagate Desktop drive (CystalDiskInfo says it is a ST8000DM004-2CX188, haven't shucked it yet). The interesting thing is, CDM shows normal (as in "not SMR") values for 4K writing (same as for reading, about 1 MB/s), unlike about 10 MB/s, like for example my other 5TB SMR drive.

wheel Posted January 24, 2019 Share Posted January 24, 2019 (edited) So last month, I started having some issues writing to certain 8TB drives, but never took note of which specifically since no parity errors ever popped up before or after checks. I was looking into adding more 8TBs to a 19-disk array this week when I realized I’ve been adding ST8000DM004-2CX188s left and right over the past couple of years. SIX disks in a nineteen-disk array (not counting parity) are SMR drives (one is ST8000AS). Some have been going for years with decently intense read use and no real issues now, but reading this thread has me kind of freaking out about the possibility of multiple SMR drives failing simultaneously. Instead of looking to expand, which I still really need to do, I’m now wondering if I’m better off using my next 3-4 HD purchases to replace some of these 8TB SMR drives before I even try swapping some 4 or 6TB drives out with 8TBs. If I’ve made it this far without any failing (three pre-shuck preclears on each drive, too), is there any safe way to stress-test each SMR drive individually and maybe figure out which should be replaced first - or, ideally, if some look like they’ll be more reliable than others, which can stay in safely for awhile, so I don’t need to immediately replace 4 and just leave those 8TBs lying around to eventually replace the SMR 8TB “slot” whenever it inevitably fails? Whole situation feels wasteful, but that’s on me for continuing to buy these drives without looking here for guidance each time... Any help or ideas would be greatly appreciated! Edited January 25, 2019 by wheel Realized I had an 8000AS disk, too 1 Quote Link to comment
