The partitions on 512e Advanced Format drives need to start on a sector which is a multiple of 8 (4KB / 512B = 8) otherwise the drive performance will be quite poor. The first 33 bytes are reserved for the GPT label, same goes for the last 33 bytes, which are reserved too. This script scans for Toshiba DT01ACA300 drives on a perc800/810 controll…
