Today, I was converting a system from single drive to mirrored with a 2nd 80GB drive. Here is proof that there are drives that both claim to be 80GB, but happen to be of different capacities: sd 0:0:0:0: [sda] 156301488 512-byte logical blocks: (80.0 GB/74.5 GiB) sd 2:0:0:0: [sdb] 156250000 512-byte logical blocks: (80.0 GB/74.5 GiB) > So, if i understood correctly, you use partitions on something which > isnot a real HDD, hope you got the data alignment part correct. You have misunderstood, and yes we are using partitions on real drives, and indeed yes, we've got the alignment part correct. Cheers, Iordan
