Problem creating new partitions in DriveSetup

[kallisti5]

As of hrev47345, gcc4h you are unable to create a new partition.

Steps to reproduce:

• Open DriveSetup after booting ISO
• Create a new Intel partition map on an empty disk
• Partition -> Create remains disabled.

As this would impact new installs, i'm setting this one to Alpha 5 with a blocker status.

recent drivesetup changes: ​http://cgit.haiku-os.org/haiku/log/src/apps/drivesetup

recent intel disk system changes: ​http://cgit.haiku-os.org/haiku/log/src/add-ons/disk_systems/intel

recent kernel add-on changes: ​http://cgit.haiku-os.org/haiku/log/src/add-ons/kernel

The recent drivesetup changes seem like the most suspect based on timing alone.

possibly duplicate #7930

From the screenshots, it seems it already fails at creating the partition map. If that works correctly, it shows a "<empty>" entry on the disk, when you select that, create partitions is enabled (see screenshot below).

Unfortunately I can't reproduce it here, with hrev47380 in virtualbox, it works fine... could you use a current hrev and only replace the DriveSetup binary in it with one before the recent changes and try it with that?

There are at least two problems here:

• The intel partition map not willing to create a partition map (possibly it detected something else on the disk?)
• Complete lack of error reporting in DriveSetup, so we have no idea what really happened.

I have a feeling this is a duplicate of #8823. If the disk contains a GPT backup map at the end of the disk, you are unable to create a new MBR table or partitions as the GPT add-on attemps to load as well.
