Hi,

$ sudo parted --script --machine /dev/sdd unit s print
Error: /dev/sdd: unrecognised disk label
BYT;
/dev/sdd:7744512s:scsi:512:512:unknown:Generic STORAGE DEVICE:;

The two last lines are printed in the standard error output instead of
the normal input. Because of that, I must redirect the standard error to
the standard output in order to read the disk size.
IMO, only the error message about the unrecognised disk label should be
printed on the standard error.

Are you sure? The code handling that is pretty straightforward:

https://github.com/bcl/parted/blob/master/parted/parted.c#L986

puts and printf, no stderr involved.
