RAID 1 Mirror Error with Two Western Digital 500GB Drives

by bm678 / July 7, 2012 4:47 PM PDT

I have Windows 7 Ultimate 64 bit installed on a Western Digital 500GB drive (WD5000BEVT-22ZAT0) that was partitioned automatically by Windows as 100MB System Reserved and 465.66GB drive C. There is also an unallocated second Western Digital 500GB drive (WD5000BPVT-22HXZT1) that I want to use for RAID 1 to mirror the first drive but I get an error message stating "All disks holding extents for a given volume must have the same sector size, and the sector size must be valid." I uninstalled Windows patch KB-982018 but I still get the same error message. Could you please let me know how to resolve this? Thanks.

Does the program that gives this error message offer you the opportunity to show and change that sector size?

I use "Add Mirror" in Disk Management feature of Windows 7 to do RAID 1 and it does not show any options to change the sector size.
