I've never seen it do that before with a pre-cleared drive. Drive is new from amazon, delivered only on monday...... never been in my array at any time since then. I'm worried that if i select clear on that screen that i'll lose the array for nearly 2 days while it clears.

March 26, 201511 yr Author I've just updated the preclear version to 1.15 after seeing something about previous versions not working properly in 64 bit 6.0 started preclearing the drive again. will report back in nearly 2 days, damn........
March 29, 201511 yr Author After getting a later version (1.15) of the preclear script, and preclearing the drive with it, that things are ok and the drive is now part of the array and currently being used as destination drive for first of my drives to be converted to XFS.
