would this work as a replacement? IO Crest Internal 5 Port Non-Raid SATA III 6GB/s M.2 B+M Key Adapter Card for Desktop PC Support SSD and HDD. JMB585 Chipset

20 ours and 16 passes on memtest with 0 errors.

It's at 3.9 TB with over 100k sync errors. I am canceling the parity check and am sending diagnostics. I will reboot and start memtest. tower-diagnostics-20200104-0409.zip

Hi, I could sure use some help. I have been upgrading my server with new drives over the past year and I am getting enormous number of sync errors. Most recently I installed a new 8 TB Parity drive and 2 new 8TB data drives. All pre-cleared 2 full cycles. Moved files from older 4 TB drives to 8 TB. Ran sync. Everything was okay. Copied some files (about 300GB) through thee cache drive. Moved the files then ran sync. Over 86,000 sync errors reported. I shut the server down afterwards. I have waited several days and just booted the server just over 1 hour ago. No files have been accessed no addition made to the server. After 256GB synced out of 8 TB there is over 600 sync errors and climbing steadily. 75% of my hours on all my drives is parity checks. Prior version of UnRaid 4.7 there wasn't a parity error for years. Since moving to UnRaid 6 series 6.4 & 6.5 I have had a constant barrage of sync errors. I thought it was a problem with the parity drive but that has been replaced and the problem persists. I also replace every disk drive cable. I have uploaded my hardware profile

Dolphin worked like a champ. I am rebooting now so I will verify that it is done. It appears to be fine parity is now rebuilding. Hoopster & itimpi Thank you for all your help

Hoopster, I relocated to Raleigh a few years ago and one is place under substantial pressure to choose which color blue you are. I finally opted for Duke. March madness is unbelievable here. itimpi, I will try your recommendations and let you know how it turns out.

itimpi I have an old system that is in need of substantial upgrades. I use it to store media files 20+ TB. It was recommended awhile ago not to use dockers with my old Sempron CPU. I still have a few old plugins but that's it. In a nutshell this has been so reliable all these many years when I do need to do something like upgrade disks I have to retrain myself. The bad part about that is sometimes I think I know what I am doing. Scary. Right now I am upgrading drives to 4 TB and already looking at economics of larger and fewer drives. The expense is that I maintain two full backups. Next will be everything else. Yes I can see the individual drive across the network. I am not sure how your recommendations will work with the directory structure being "disk 3/S/DRAMA" creating "S/S/DRAMA". Although I could probably move the drama directory up one level and the delete the other S directory

It is definitely user shares. After reading your recommended threads I think the best way is to format a blank disk and then delete the share. My question is the share name on the disk itself and will it pop up when I reinstall the disk? Yes I did name it disk 3 and it didn't have a problem with that. Perhaps they need to add disk with a space and number to the reserved list. I am going to prep a small 1 TB drive and put that in the disk 3 slot and try renaming that. I will let you know the results. BTW are you a Duke or North Carolina fan?

I just tried pulling the drive and run reconfig. Showed disk was deleted. rebooted with drive installed and configured my disks and of course it was disk 3 again and I still can't rename it. The last option I can think of is to format a drive and plug it in then reconfig with a blank drive and hopefully be able to change the name then. If there is any other method that is less time consuming I would certianly appreciate any recommendations.

What is described in those posts is exactly what I tried. In the share I changed the name to "S" and when I clicked apply it reverted back to Disk 3 stating it is a non empty disk.

I just added a new 4 TB disk replacing a 2TB drive. I apparently errored in naming the share name as disk 3 instead of S where all my videos are. I have already copied 3.3 TB onto the drive and I can't change the share name. Any ideas on how I can correct my faux pas?

I have been replacing drives primarily when I can double the storage capacity for less than $130 which I have been doing going from 2 to 4 TB. 8 TB drives are within the same price range if I reduce the number of drives. I have became concerned the SMART reports knew something I didn't and I would be better off adding more 4 TB drives because the 8 TB would need replacement before their useful life (filled up) ended. It would be of great interest to me if we could study users experience in drive useful life. I think that head fly time, reallocated sectors and additional info would be a better indicator than just physical age. The oldest drive in my system has power hours of 9+ months over ten years. I think it would be helpful to all to address this based on environment (business, home media, etc.) and develop a more meaningful measure of age. I believe this is available from large server farms but I am sure they use much larger drives.

What constitutes an old drive. I have 6 data disks (16 TB) plus parity and cache disks. This is a simple home media server and the most exercise any one disk gets is the monthly parity check. Normally, when I add media to the server it is collected on my PC (4 TB) over several weeks (sometimes months) and added at one time. The server is shutdown for extended periods because the fans are so loud. I added three 4 TB drives (1 parity 2 data) 18 months ago and now they are suffering from old age? I have some 2 TB drives that are 10+ years old without a single hiccup. How is age determined? Even when my server is on, the drives are spun down. The only time a drive ever reaches 90 degrees Fahrenheit is during a parity check otherwise they never get above 82 when spun up individually. Drive old age is one of the first things that is pointed out when seeking any support and from what I can see it is not based on read write time nor spun up time but from the time it was installed. It appears to me that there must be a better way to determine a drives age. What I try to watch is sector reallocation. When that starts on a drive I want to know about it immediately so I can replace it. I believe most of us use this as a media server and we are not managing a server farm where you are engaged in constant read write time. Is there a better way to determine when to replace a drive? It has been my experience that if it isn't broke don't fix it.

no

This is what I have discovered about undeleting files. I discovered the home user version after I decided to restore my files from a backup. I only had around 60 files that needed to be ripped again. I opted for this when I initially saw the price tag for the professional systems could be in $1000 range with the various modules and didn’t look further. Here is some info on the home version called “Raise Data Recovery Software.” https://www.sysdevlabs.com/services.php?tab=drserv Sysdev Laboratories UFS Explorer (Big bucks) For home users Raise Data Recovery software (undelete) All software is installed on a Windows machine. General license Windows NTFS, FAT/FAT32, exFAT 30 days 15 Euros 360 days 20 Euros Lifetime license with free updates for the duration of term renew at 50% Ext2, Ext3, Ext4, JFS, ReiserFS, UFS and UFS2 file systems of Linux 30 days 13 Euros 360 days 18 Euros XFS file system 30 days 13 Euros 360 days 18 Euros For all three of these packages assume about $65 for 1 year and renewal is at a 50% discount. While I do have one btrfs file system on my cache drive the rest are XFS. It would have been worth it to buy this for $65. But there was still no 100% guarantee that it would be successful. I hope this is helpful for the next person.
