This used to be the case, but Eric has changed the Linux SCSI disk
driver so that sector sizes of 256, 512, and 1024 bytes are supported.
So, upgrade to a newer kernel and you shouldn't have any problems.

No.

On many SCSI disks, you can change the block size with an
appropriate MODE SELECT command followed by an appropriate
FORMAT UNIT.
