dotSlash Posted August 15, 2021 Share Posted August 15, 2021 Just added a 8tb hdd to my 5 disk stash, the disk was all good when in disclosure. after two days the disk appeared disable, so I did a parity check on it. 54,250 Errors! but theres little to nothing data on the disk yet. Checked the SMART test and all passed. Should I be worried? Anything I need to do? unraid-diagnostics-20210815-1649.zip Quote Link to comment
JorgeB Posted August 16, 2021 Share Posted August 16, 2021 Looks more like a connection/power issue, replace/swap both cables and try again. Quote Link to comment

A bit confused by this as any disabled disk would not take part in a parity check. Maybe you meant something else? 8 hours ago, dotSlash said: 54,250 Errors! but theres little to nothing data on the disk yet. The amount of data on a disk is irrelevant to a parity check as its is working at the raw sector level. Even a disk that has no data will have a lot of non-zero sectors due to the fact that the disk was formatted to create the control structures for an empty file system. Quote Link to comment

Possibly it is out-of-sync though due to problems. 18 hours ago, dotSlash said: 54,250 Errors! Where did you see this number? Quote Link to comment
dotSlash Posted August 16, 2021 Author Share Posted August 16, 2021 Quote after two days the disk appeared disable, so I did a parity check on it. I mean the server was running fine for about 2 days before I discovered the new added disk was disable. Here is the errors. Quote Link to comment

trurl Posted August 19, 2021 Share Posted August 19, 2021 Connection problems with ata3. Unfortunately all syslogs in diagnostics filled up with those message so nothing from earlier to see which disk that is talking about. Quote Link to comment
