Format SAS drive with 520/524/528 byte block size

August 15th, 2014, 15:48

So, for example I have Seagate Constellation ES.3 or Toshiba SAS drive that is formatted with default 512 sector size.
In specification it says
Code:
*User-selectable logical block size (512, 520, 524, or 528 bytes per logical block)

How can I reformat it to 520/524/528 byte sector size?
Any ideas? SeaTools can't do it.

You need a controller, which supports corresponding sector size.
"Normal" controllers do not work with non-standard sectors, while the "abnormal" ones are capable to write metadata to the surplus bytes.
