This is strange.
Installed the VR 500 drives in raid 1 recently.
First thing I did was install and format it under 7 to which is was recognized as AF and I aligned it and benched it.
I then removed the partition and put it into a XP machine and had RST rebuilt to it.
The drive shows up as non-AF and shows aligned which it should not be.
Strange further the drive is still extremely fast in all benches as it is.
As of now I have no idea if it is aligned or not, WDalign says it is even though it never was.
I tried a trick and removed the drive with metadata to the 7 machine as it might recognize it is not aligned, same scenario.
I could try to partion and format it under 7 so the physical disc is correct and then insert into XP, the logical should then align and if not just maybe WDalign will recognize it and do it’s job.
