January 6, 20206 yr Hi, i have 5 Drives in my Arry + 1 Parity. One Array drive has some unreadable Sectors. Is it possible to tell unraid mark and simly dont write these Sektors? It should be possible, cause unraid know these Sektors.
January 6, 20206 yr Community Expert This is not a feature that Unraid provides. With modern drives this sort of issue should be handled Internally by the firmware on the drive and any bad sectors reallocated to use good ones.

Modern HDDs firmware has been effectively doing with this for quite some time now (e.g. reallocate bad sectors to good spare ones and thus preventing uses of these bad sectors). If your HDD has bad sectors, it is usually an indication that it is failing though. So you will want to watch the count and if it's steadily increasing, replace your HDD (with urgency). I personally replace a HDD as soon as any bad sector is detected.
January 7, 20206 yr Community Expert Looks like you were talking about disk5. It has more problems than you mentioned: Serial Number: WD-WCC4E1XJRHNC ID# ATTRIBUTE_NAME FLAGS VALUE WORST THRESH FAIL RAW_VALUE 5 Reallocated_Sector_Ct PO--CK 163 163 140 - 1100 196 Reallocated_Event_Count -O--CK 056 056 000 - 144 197 Current_Pending_Sector -O--CK 199 199 000 - 782 198 Offline_Uncorrectable ----CK 200 200 000 - 378 2 hours ago, Gee1 said: I will take it to the trash.. thx -closed- Definitely Do you know how to rebuild to a new disk?
