Can udisks be removed from 14.04 and replaced with the functionality of disk utility from 12.04?

The older 3.0.2 source should still be viable thru 14.04 as most of the deps are available for 14.04. However better to rebuild & package for trusty as an upgrade to current gnome-disk-utility package, so to that end a ppa.

Notes: Uses the last 3.0.2 source in Ubuntu - 3.0.2-2ubuntu7 precise (- the package name inadvertently got 8 at end, no matter really.

Only real change was to remove nautilus extension & launchpad integration as no longer working or used & would cause a ftbfs.

The default opening window size is a bit small, needs to be resized or maxed after opening. If I stumble upon a way to adjust in source will do so. ( patch welcome.

If unsuitable then either use ppa-purge or just remove ppa, remove gnome-disk-utility, update sources & re-install current gnome-disk-utility.

Copied over a previous build to ppa for saucy (saucy is almost EOL

As far as usb creator, the 14.04 version is fine, just format the flash drive first to fat32, then open usb creator and it should work ok.

I've checked the source of gnome-disk-utility from their git repository and the problem is that on 32bit architectures it uses 32bit lseek() function to seek the signed offset. So it succeeds for the first few seeks, but then it fails beyond 2^31 bytes (2560872448 is beyond this bound).

Based on the manual of lseek64 the fix is either to add just one line before all headers:

#define _FILE_OFFSET_BITS 64

Or switch to lseek64 prototype.
