Hi all,
[My name is Bjørn Forsman, end user of parted, I'm using parted as my
primary partitioning tool.]
When I run parted (latest version, 3.2) on an ISO file, it gets
confused about the block size:
$ parted ubuntu-16.04-desktop-amd64.iso p
WARNING: You are not superuser. Watch out for permissions.
Warning: The driver descriptor says the physical block size is 2048
bytes, but Linux says it is 512 bytes.
Ignore/Cancel?
If I select "Ignore", it misinterprets the size and the partition table:
Model: (file)
Disk /home/bfo/Downloads/ubuntu-16.04-desktop-amd64.iso: 5944MB
Sector size (logical/physical): 2048B/512B
Partition Table: mac
Disk Flags:
Number Start End Size File system Name Flags
1 2048B 6143B 4096B Apple
2 1479MB 1481MB 2425kB EFI
And if I select "Cancel" it gets the size right but doesn't show any more data:
Model: (file)
Disk /home/bfo/Downloads/ubuntu-16.04-desktop-amd64.iso: 1486MB
Sector size (logical/physical): 512B/512B
Partition Table: unknown
Disk Flags:
Why cannot parted handle this like fdisk?
$ fdisk -l ubuntu-16.04-desktop-amd64.iso
Disk ubuntu-16.04-desktop-amd64.iso: 1.4 GiB, 1485881344 bytes,

Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

I wonder if commit f98f791e19669b900345dad7d96ea4df974e4596
("libparted: device mapper uses 512b sectors") fixes this.
This commit is from february 2015. Any plans on making a new release?
(I'm an end user, I use released software.)
Best regards,
Bjørn Forsman
