Hello, (sorry if duplicate, but my previous send doesn't seem to appear
on the mailing list !)
I got a problem here with my MBR partition table and parted 3.2 which
only detects a "loop" partition table while 2.3 is ok.
----------------------------------------------------
Things are working perfectly with parted 2.3:
GNU Parted 2.3
Using /dev/sda

However, parted 3.2 does not read the partition table properly anymore
and goes in "loop" mode:

----------------------------------------------------
Note: I am using the GParted Live CD's, booting them, so I have no way
to test any version of parted other than the ones on these CD's, which
are 2.3 and 3.2 to date.

Besides that, lsblk, fdisk, cfdisk, fsdisk all work perfectly:

I suspect the problem is with my MBR contents ...It has Grub4dos in
there, to multiboot between my DOS, XP and Win7 partitions.
Problem is happening whether it is version 0.4.5c o 0.4.6a.
In case that can help, here is the contents of my /dev/sda MBR

----------------------------------------------------
So I am at a loss .. what is going wrong which makes parted 3.2 not
interpret my partition table correctly, while parted 2.3 is ok ?
How should I correct things ? (or is there a bug in parted 3.2 ??)
Thank you in advance for any feedback .. or ready to provide more if you
suspect a problem in parted 3.2.
Thanks, and best regards, Erwin9
