How to format WD20EARS using Intel Rapid Storage Technology Raid 1


I purchased 2 WD20EARS for my desktop and have them running in a raid 1 array with Intel Rapid Storage Technology.  The drives seem to be working correctly, however when I check the array properties it says the physical sector size is 512k bytes.  Should I reformat the drives with a 4k sector size?  

I also have the same question.  Ever find a solution?

It may be an intel issue.  When i ran chkdisk it reported the 4096byte sector size, but the intel utility still shows 512byte logical sector size.  I just chatted with intel support and they said that the issue hadn’t been reported.  The update supposedly improves compatibility for the advanced format drives.
