Map Out Bad Sectors on an array disk

[Gee1]

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.

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.

You should post your diagnostics so we can get a better understanding of your problem and suggest how to proceed.

What you are asking for is a DOS era implementation.

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.

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

Do you know how to rebuild to a new disk?
