It probably won't notice at all :), since it would only try
transactions in multiples of 2K which are still supposed to work even
if the drive supported a smaller blocksize.

If the drive supports 512-byte deblocking, you can of course also
mount a UFS CD-ROM then. :) (Or to 2K blocksize devices work with UFS
now?)
