I recently had to do a recovery but it would not take on my primary drive. The computer came back and said that it could not recover to the current volume and asked if I would like to recover to the alternate volume (my slave drive). I said yes and the recovery was successful although now I had to switch the drives jumper settings and reinstall them. Now the computer boots up OK but only after the second boot. I have done a chkdsk/f and the process did relocate some files at which point I thought that would make a difference but it did not. Can anyone think of anything which would cause this boot on the second try only problem???
