You mean GParted or diskpart? GParted is a graphical frontend to GNU parted; diskpart is a CLI tool from ReactOS/win32 land. Either way, to be helpful here, when running parted (as root) you can do (i.e. for sda):
parted /dev/sda mktable msdos, or from a bootable ReactOS nightly (or a Windows) disk, run
diskpart, then (i.e. for disk 1 in the list)
select disk 1, and then run
clean. But, be aware the ReactOS version isn’t fully ready yet, so using GParted or Redmond’s version of diskpart will probably be safer choices.
Another option on a Unix(-like) system, including OpenIndiana and Mac OS 10.0+ is to run
dd as root from the Terminal to write out zeroes to the disk over the first part of the disk. That may also be helpful as it should help ‘reset’ things, after which you can use DriveSetup, Disk Utility, Gnome Disks, or whatever disk utility you prefer to set the disk up. As for formatting problems, it’s pretty rare (most of the time, it does work as intended), but I have had DriveSetup mess up before; to remedy this, run
parted /dev/sda mktable msdos (for a legacy table, which I’d recommend unless you need GPT), then do
parted /dev/sda mkpart primary with 100% of the disk to create a single volume. After restarting into Haiku, DriveSetup should be able to create a BFS (or “BeFS” in modern parlance, since there’s another BFS out there) volume for you and install with no problems. But again, as others have said, I haven’t had much trouble with DriveSetup so I’m not sure what’s going wrong.
I have, however, had where Haiku doesn’t always write the boot sector as advertised. The quickest fix for this is just click “Write boot sector” from the Tools menu, then click Quit or Restart. But always remember to run bootman after the first phase of installation is done, even if Haiku is the only OS on there. I suppose for a simpler install you could image out Haiku and write the image to the drive directly, but that might be harder than doing the three step format -> install -> bootman path.
As for the other issues (like the returning WiFi box), looks like they’ve been answered already. But I do hope you don’t give up on Haiku, as it’s still getting to R1, but is a great little system. Granted, not all the hardware will work on everything, but it’s definitely doing what it can with the sea of hardware out there. Hope all of our answers help… and good luck with everything!
