DS1515+ I/O error

Unread post by shark1971hk » Thu May 17, 2018 8:40 am

I received the warning message: I/O error occurred on Hard disk 4 and Bad sector was found on Hard disk 4.

But i run the Health Info s.m.a.r.t test (Quick or Extended) on my Hard disk 4 it show normal. Consistency check completed and no error, on bad sector at all.

Is it a device failure or hard disk failure?

The drive has most likely replaced the sector with one from its pool of spares. Just keep an eye on it - if it continues to find errors the drive should be replaced, especially if it is still under warranty.
