From: a <mapibid <at> hotmail.com> To: "bug-parted <at> gnu.org" <bug-parted <at> gnu.org> Subject: parted 3.2 fails to read MBR partition table where parted 2.3 was ok Date: Wed, 9 Mar 2016 22:33:16 +0000
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:

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

I can bring some more details: the problem definitely looks to be that parted 3.2 doesn't like the GRUB4DOS MBR (see dump contents I supplied at end of in my first post), while parted 2.3 is ok. Indeed, when I reset the MBR with bootrec /FixMbr from a Win7 boot CD, everything is ok in parted 3.2. And as soon as I reinstall GRUB4DOS, no matter which version (0.4.5c or 0.4.6a), parted can't read the partition table anymore. Still, the partition table itself (0x1BE to 0x1FE) is totally identical in all cases. So something in the rest of the MBR contents, between 0 and 0x1BD, is not digested by parted 3.2 ... are you able to tell what ? GRUB4DOS being quite spread and used (Grub2 is too complex to configure and requires to have a Linux install, which I do not have), parted should compose with it like other Boot Managers .. shouldn't it ? Thank you for any hint/help or let me know if you need anything more, Erwin9

[Message part 1 (text/plain, inline)]
I like to add that GRUB4DOS ist widely used on bootable pendrives e.g. with MultiSystem. So would be helpful, if it would be treated by parted. -Ulf Am 10.03.2016 um 00:23 schrieb a: > I can bring some more details: > > the problem definitely looks to be that parted 3.2 doesn't like the > GRUB4DOS MBR (see dump contents I supplied at end of in my first post), > while parted 2.3 is ok. > > > Indeed, when I reset the MBR with bootrec /FixMbr from a Win7 boot CD, > everything is ok in parted 3.2. > > > And as soon as I reinstall GRUB4DOS, no matter which version (0.4.5c or > 0.4.6a), parted can't read the partition table anymore. > > > Still, the partition table itself (0x1BE to 0x1FE) is totally identical > in all cases. > > > So something in the rest of the MBR contents, between 0 and 0x1BD, is > not digested by parted 3.2 ... are you able to tell what ? > GRUB4DOS being quite spread and used (Grub2 is too complex to configure > and requires to have a Linux install, which I do not have), parted > should compose with it like other Boot Managers .. shouldn't it ? > > Thank you for any hint/help or let me know if you need anything more, > Erwin9 >

It seems that your hexdump of your MBR was line wrapped by your mail client, corrupting it.
