Re: Using Advanced Technology 4K drives

You should have no trouble using drives with 4K sectors. md RAID5 and RAID6 already do almost all IO in multiples of 4K, so no change in behaviour is needed.

I think the most likely cause of problems is if you use an old version of fdisk to partition the drive, and get partitions that are not aligned to sectors. So when (if) you make partitions, just check they are aligned properly, and everything should be fine.
