Description
This may be a duplicate, but I didn't see any close tickets.
Process:
- Create GPT partition map on device in DriveSetup
- Create a GPT partition (Haiku / BeOS) in DriverSetup
- Receive general system error.
Can reproduce on any disk / usb disk

resolved in hrev49309. A todo item to assign the alternate header was preventing Haiku from creating the disk system properly. gpt headers / disk systems created with Haiku are now seen as valid by gdisk!

Hi Kallisti,
yesterday i tried to create a new partition on my GUID disk with DriveSetup (it was some hours before your commit hrev49309) on my HDD (it is a 1T HDD with 4K sector size)
DriveSetup listed nicely the GPT partitions, and the gap space between the partitions. I deleted a partition to get free space for a new partition, and made a new with BFS. I noticed, that Haiku made no gap space between the old and the new partition (<- it could be important, i don't know) but everything went without problem and i got no error message. After that i installed Haiku onto the new partition and installed the bootrecord into this partition.
After my primary OS was not able to read the partition system of the modified disk, so i lost all of my other partitions and data. Nothing serious, i just restored everything from backup.
Is your commit fixing this problem? If not, can we disable the partition creation on GPT disks? It would be bad experience for the users losing data because our unfinished or buggy GPT partitioning support.
Thanks! miqlas

It would be great if you would have made copies of the blocks of your GPT disk after Haiku changed it. Could you still access those partitions from within Haiku?
If kallisti5's changes fixed that, I'd say the other OS's GPT is buggy, as it actually should be able to read it just fine -- that's why there are two GPT blocks to begin with.

Hi Axel,
no, i recreated the partitions and restored everything from backup yesterday midnight. I will test the kallisti's commit at weekend, but not on my productive HDD anymore (i know, i know...) I have some USB thumbdrive, i can create GPT partitionig system on that too, and then i can modify them in Haiku without risking my data. I think it could be a good test, right? If it doesn't fixed with this commit, i can provide the info what you need to debug this problem.
What i've seen: Haiku can reinitialize any GPT partition to BFS correctly, but during deeleting and recreating a partition on GPT in Haiku somewhere something went wrong.
I have no info about how good or bad is the GPT implementation of my primary OS (OSX 10.10.3 Yosemite), but i had no problems like this before.

The bottom line is: if Haiku was still able to read the GPT table, other systems should be, too. If they can't they are likely too strict. I've created a GPT table years ago with Haiku, and didn't have any issues with it yet on various systems (Windows, and Linux).

Axel, maybe i made something wrong, or there was problem with my GPT partition scheme, i can't say for sure, that Haiku is guilty. OSX was unable to read the partition table, so i started to restore everything and i forgot to check the disk in another OS or in Haiku.
I will test and report back at weekend.
Thanks you guys!

There is no question Haiku was guilty, it just might have been less interrupting for you if OS X would be more forgiving :-)

"on my HDD (it is a 1T HDD with 4K sector size)" " After that i installed Haiku onto the new partition and installed the bootrecord into this partition."
4K sector size + bootrecord == #11796
I'd try it without the bootloader to see what happens... however i'm pretty sure our bootloader is also unaware of GPT.
I've yet to have a 4k disk to test haiku on. (I wonder if I can emulate one?)

I doesn't explained it correctly, let me try again: I had a Haiku partition before this catastrophe on the same HDD, on GPT partition. I made the partition in OSX as FAT and then initialized in Haiku as BFS and installed bootrecord. It worked without problem, i was able to boot it with the Haiku bootmenu installed to a USB drive (MBR).
Now as I experimenting with Clover legacy boot i tried to recreate the partition in Haiku because Clover was not able to detect the "FAT-reinitialized-as-BeFS" partition as bootable partition. I thought maybe something wrong with the reinitialized FAT partition, because the diskutil tool in OSX told it is a "Microsoft Basic Data" partition.
So i started Haiku, opened the DriveSetup, and it presented the partition table:
- USER partition
- Empty space (gap)
- HAIKU partition
- Empty space (gap)
I deleted the Haiku partition, now DriveSetup presented the following partition table:
- USER Partition
- Empty space (gap)
I tried to recreate the Haiku partition, so i went to the menu, and created a new partition on this empty space. This is what i got:
- USER Partition
- HAIKU partition
See? No gap anymore. I'm not sure if it is requiment or not, but after this step OSX was not able to read the partition table anymore.
Sorry, i forgot to test the result in Haiku, but i was able to install Haiku into the new partition.

see #12170 This is a new issue. Please keep in mind that this is all *extremely* young code in an alpha operating system... I wouldn't use the GPT functionality on live data for a little while.
unplugging and replugging the usb device results in the "create" option being disabled.
