Write error on disk block but format read is OK

PLATFORM DESCRIPTION
T3-2
Solaris 10u9

PROBLEM DESCRIPTION
Two disk write errors on disk blocks. The format/read throws no defect on the surface. I would like to know how to determine if the write error was due to a disk defect or to another source. Morover, I would like to know how to early detect future write errors on disk.

Following error is showed in /var/adm/messages:

scsi: [ID 107833 kern.warning] WARNING: /scsi_vhci/disk@g5000cca012b51c24 (sd0):
