Hello, parted just crashed on me and told me I have to report the bug. :)
I have a USB memory stick that I want to repartition. parted complained, with a "Ignore/Cancel" prompt. I am reminded of MS-DOS: https://en.wikipedia.org/wiki/Abort,_Retry,_Fail%3F Possibly an improved error message would be a good idea? Anyway, I chose "i" for ignore on the first run. However this results in an incorrect size for the USB stick, which I know is 16 GB. ----------------------------------------------------------------------- shane@pallas:~/tmp$ sudo parted /dev/sdb GNU Parted 3.2 Using /dev/sdb Welcome to GNU Parted!

Better, I guess? Probably I should have paid more attention, as the "i" for ignore version at least could read a partition table. :) Anyway, I proceeded to try a new partition: ----------------------------------------------------------------------- (parted) n Warning: The driver descriptor says the physical block size is 2048 bytes, but Linux says it is 512 bytes.
