I have been running a 12TB, i7, 32bg of ram server for many years. It uses 4 Ironwolf drives (one for parity) and a 1tb SSD for cache. I use it for archiving, backups, plex and occasional virtualising plus it has a few dockers etc. It has been a great machine but its bulky and produces a lot of hot air and noise so I start looking at mini pc options; something like the Beelink ME mini or similar but although they are small and quiet I think that type of computer isn't going to it. They may not even run unraid properly. Does anyone have any suggestions for an alterative build, either ssd or M.2, I liked to keep the option of virtualisation but if its a deal breaker then happy to for go. I'm just tired of my house being filled up with hot air and noise! TIA

Thank Trurl for your help. I have rebuilt to another disk and ordered some new sata leads.

I've used this process; is that the best thing to do? https://wiki.unraid.net/Manual/Storage_Management#Rebuilding_a_drive_onto_itself

Hello. I'm always getting CRC errors and sometimes they get so high I have to return the drives to Seagate. I'll invest in some better cables. How do I re-enable the disk? Thanks for your help.

Thanks for your help trurl, please find new diagnostics attached. All the cables were connected fine, could it be bad cables? fileserver1-diagnostics-20211205-1653.zip

Attached. Thanks. fileserver1-diagnostics-20211204-1518.zip

I opened the dashboard of my server today to find a hard drive had once again been disabled. I've attached the smart report, could someone have a look please and see what the problem could be before I do anything. I do have a hot spare in the box if needed. Also, when spun up my drives are running at 16 degrees C which seems too cold to me, should I try unplugging the case fan over winter till my house warms back up, thoughts? fileserver1-smart-20211204-1346.zip

Hi JorgeB. As grateful as I was for your response I was tearing my hair out thinking I had lost all that data. However after following your instructions and rebooting the server, all the shares are working and my data is accessible! This is amazing. I have still posted the diagnostics file in case you can help me prevent this from happening again. Certainly advice on best practices to storing data would be appreciated, should I run two parity disks or get a bigger case as my Fractal design node 304 is pretty tight.

Hello, Over the past year I have been getting increasingly frequent reports of the UDMA CRC numbers increasing on each hard drive in my server and eventually the drives would become disabled. I started off replacing my old WD drives from a previous server with IronWolf 4tb drives but the problem kept happening even after I had sent the drives back for repair to Seagate. After I did some research I found that the increasing numbers were nothing to be that worried about and could be down to poor SATA cables or even bends in the cables. I improved my cable management and rebuild the current drive that had been disabled and all seem fine. Cut to yesterday when it happened again, however this time when I rebuilt the drive the parity check passed but the data isn't visible. Unraid shows the correct drive percentage under the 'Main' tab of the GUI but browsing the drive by clicking the file logo gives me the message 'No Listing: Too many files'. The shares have disappeared from the 'Shares' tab and windows cannot access them either. The drive with the problem is drive 4 in my set up but drive 3 (an old WD) is also giving me the same problems and creating thousands of error lines. I have one spare (brand new Ironwolf) drive to swap into the box if needed but don't want to try this until I'm sure this will help and not hinder the problems. I have attached the zip file from the diagnostics page (as per the 'Read me first' post on this forum) and downloaded all the SMART reports in case they are helpful later. I am running Unraid 6.9.2 with these plugins: Recycle Bin, Unassigned Devices, Community Applications, Disk Location, Dynamic Active Streams, Dynamix SSD Trim, Fix Common Problems, Preclear Disks, Unassigned Devices Plus, unbalance, User Scripts. My hardware is a ASRock H370M-ITX, i7-8700 with 32g RAM. Any help is much appreciated. fileserver1-diagnostics-20210714-1733.zip
