[Message part 1 (text/plain, inline)]

Reason of this "message bug" is: search line with "###" !

============= End Output ==============================

I think, that the message "###" is not a error, because:
1. already undestand, that the disk cant have disk table and do not have
labels of partitions (already="unknown" table)
2. for "--machine" output need strong/constantly output, without "sudden
messages" (without ";" at end of line)

Please remove this message from stderr - it is not a error and this message
hinder to "--machine" output!

=============== End Output ===========================

1. This "Output" contains "Carrage return" as 1st simbol
2. Then contains a lot of spaces.
3. After "BYT;" - has symbol, that i can't recognaize (I am not cool Python
programmer :-) )
4 and than goes 3 spaces (after this symbol)

I think, that it is very bad output/ These symbols not must be in output!!!

PS: Before, i rebooted and a lot of spaces was after "BYT;" (but i have not
this python script)

If you use --script it will return a 1 in this case.

I agree, somewhat, but it would be difficult to squash parted's normal
exception handling for cases like this. Note that it *is* output on
stderr so if you don't want to capture it just grab stdout. And if you
use --script it will return a proper error result code.

An easier way is to pipe it to hexdump -C :)

The spaces are there on purpose, output by wipe_line() in parted/ui.c

If you use --script they are not output.
