[DriveSetup] crashes in PartitionMapAddOn::CanInitialize

[diver]

This is hrev45206.

I have HTC Desire HD connected via usb in "Charge only" mode.

Clicking it makes DriveSetup crash.

If I connect it in "Disk drive" mode it works ok and I can even mount fat32 partition it contains.

Maybe some error checking should be added here? ​http://cgit.haiku-os.org/haiku/tree/src/add-ons/disk_systems/intel/PartitionMapAddOn.cpp?id=hrev45206#n91

Selecting the CD-drive leads to the same crash (I run Haiku in VirtualBox and the CD Drive map to an ISO file)

Introduced in hrev45192

Thanks korli! This means that the block size is actually reported as zero. I think this should be fixed in the upper layers instead of working around this in the intel disk system add-on.

Should be fixed in hrev45218.
