I have two WD1001FALS drives. I would like to use them in a Windows Home Server (v1) so I have to be concerned about the sector size. I’ve been searching this evening and I can’t seem to find any documentation that tells me if these drives are advanced format or not. I can’t find anything on the packaging or the drive itself the would indicate it has 4k sectors. Not sure if makes any difference, but one has a date of 27SEP2009 and the other is 15FEB2012. Sorry if this is obvious, but I just can’t seem to find it.
