WD20EARS just added on the official HCL - mistake and issues

Thanks MrCyberdude, but FYI not all WD20EARS are 4K. Mine in fact are, as the jumper settings for XP are on the label - A clear indication. I think what I was after was if any ReadyNAS guru's could hypothesize why write speeds were high while I was copying +500GB of data over several hours until I rebooted the NAS, at which point it A): Took an extra 20 minutes to reboot over normal and B): write speeds dropped off significantly. I think is is due to the 4K sectors on my drives, but why after copying copius ammounts of data? The NAS was rebooted a few times after the drive setup but before coping data - what changed? I hope NetGear lights a fire under the 4K sector support beta FW....
