Q1: Is it true that Linux can't/shouldn't boot off a RAID 5 array? Q2: The four disks have identical manufacturer, model and size, but two are brand new while two have had NTFS filesystems on them. Accordingly, if I run hdparm -g on them, two disks have these specs: geometry = 2498/255/63, sectors = 40132503, start = 0 while the other two disks have these specs: geometry = 39813/16/63, sectors = 40132503, start = 0 Is this an issue with software RAID? Thanks Michael Hall
