My storage work slowly

Hello guys,

some **bleep** was happened with my storage. After checking I can see that one HDD has may broken sectores and I have to replace it. I have questions about replacing. Storage is working under mirroring so:

  1. I have replace bad HDD with the new one, will storage fix that problem automatically and copy all data from the normal HDD to the new one?

  2. Can storage in that case work only with one HDD?

Thank you!

  1. yes, it automatically makes a copy.  Just drop in the new drive of the exact same size. 

  2. Yes, it can operate with one drive, but this is very risky.
