Description maximlevitsky 2009-09-20 17:10:08 UTC
Just after creation of the partition table, it creates a single partition that spans all the device (which is wrong), then an attempt to delete it fails:

Error erasing: helper exited with exit code 1: In part_del_partition: device_file=/dev/mmcblk0, offset=512
Entering MS-DOS parser (offset=0, size=1015808000)

IIRC, SD media only support MBR so that's probably why you are seeing this bug. Yes, it's crazy, but that's part of the spec IIRC. Not all SD readers may enforce this restriction. Does it work on other kinds of devices?

very well could be, a usb on disk keys doesn't have this limitation?
Comment 3 maximlevitsky 2009-10-22 15:27:18 UTC
Unfortunately, exactly same behavior is seen on an usb disk-on-key.
Comment 4 maximlevitsky 2010-01-22 03:28:31 UTC
Just like I explained in bug #24056, everything works fine now.
