Im trying to format sd/sdhc cards in opensuse. Creating the filesystem (mkfs.ext2) always fails as gparted tries to access the card with a "part1" , where the actual device is "p1". For example something like mccblk0p1.
I can do the same exact command with the correct name and it will work. Is this configurable to gparted to switch it to p1 instead of part1?
What version of GParted or Live CD are you using?
Would you be able to provide the output from the following two commands?
fdisk -l -uwhere one of the options is a lower case "L" and not the number one.
parted /path-to-your-device unit s printwhere /path-to-your-device is something like /dev/mmcblk0
What version of GParted or Live CD are you using?
0.4.7 (not the live cd)

GParted uses the libparted library from the parted project to identify names for devices. Hence whatever parted uses is what GParted will use.
The output listed above for parted looks like it is from the command "ls -l | grep mmcblk0".
Would you be able to provide the output from the following command:
parted /path-to-your-device unit s printwhere /path-to-your-device is something like /dev/mmcblk0
Sorry, yeah that was 'ls'

You can do this immediately after the operations fails (or succeeds).
My hope is that this might provide some clues as to what is occurring.
Here I delete the existing partition and attempt to create a new one
GParted 0.4.7
Libparted 1.9.0

libparted messages ( INFO )
/dev/mmcblk0: unrecognised disk label
========================================From the log file I can see that GParted is being passed an incorrect name for the partition.
GParted uses the libparted library from the parted project to detect and manipulate partition tables. The function call that GParted uses to read the partition name is as follows:
char * ped_partition_get_path (const PedPartition *part)
Return a path that can be used to address the partition in the operating system.
For some reason, libparted appears to be returning an incorrect device access name "/dev/mmcblk0_part1" instead of the correct name "/dev/mmcblk0p1".
To see if this problem still exists in the most recent release of parted-2.1, would you be able to try downloading the latest parted and gparted source code, compiling these, and testing the problem again?
The source code for each of these applications can be found using the following links:
Parted 2.1 Release Announcement
GParted application source code
it works correctly with the latest parted and gparted
Thank you for reporting back. It is good to hear that this problem is resolved with the latest parted and gparted.
