[Bug 484252] Re: Format action wipes all partitions

[Gary M]

precise-proposed results, tested with a 4GB USB stick having two partitions :
1. Button and subsequent warning both refer st to erasing the disk, not the partition.
2. If partitions are not mounted, they are not shown individually, instead I just see the whole stick.
3. If partitions are mounted, they are each shown, but pressing the erase button just caused the selected partition to be unmounted.  I expected the partition to be formatted or deleted.
4. If neither partiton is selected, the erase button is still enabled. I expected it to be disabled until a partition was selected.

Compounding the inconsistency, I also received the error message
"org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible
causes include: the remote application did not send a reply, the message
bus security policy blocked the reply, the reply timeout expired, or the
network connection was broken.". But this time no error was shown in the
log.

Title:
  Format action wipes all partitions

Status in “usb-creator” package in Ubuntu:
  Fix Released
Status in “usb-creator” source package in Precise:
  Fix Committed

Bug description:
  [rational]
  "Erase Disk" action formats *all* partitions, instead of the selected partition only.

  [test case]
  1) Start usb creator
  2) Select an individual partition
  3) Click on erase/format
  4) Check that the other partitions haven't been touched

  [regression potential]
  The fix has been in quantal for a while and peer reviewed before that, this fix leads to quite a bit of code being moved around but still limited to the erase/formatting code.
  As it's code doing drive formatting, regressions can be pretty nasty with potential dataloss, though I can't find any indication that it'd affect another block device than that selected and so the worst case scenario I can see is basically what we currently have in precise (wiping a partition wipes the whole drive).
