Just to let you know regarding my problem with xtool+diskspan.
It works actually, but i had to drag&drop the game folder 7 times actually (like spamming the folder into batch) before xtool starts working without windows problem reporting. It seems like a bug somewhere in batch, diskspan or even xtool, i don't know. Maybe my machine is the problem, but i had it only with xtool now.
Edit:
Have searched a bit, seems to be a problem with one of the vc redists, so i uninstalled them all, rebooted and reinstalled them one by one
Code:
Faulting application name: Arc.exe, Version: 0.0.0.0, time stamp: 0x5324af98
Faulting application name: msvcrt.dll, Version: 7.0.17133.1, time stamp: 0xc5dd3631
Exception code: 0xc0000005
Fault offset: 0x00088a2a
Faulting process ID: 0x18fc
Faulting application start time: 0x01d3d9bcfd524e85
Faulting application path: C:\Windows\System32\msvcrt.dll
The problem is only when i use diskspan with xtool. All other tools working just fine.
Edit 2:
Compatibility Mode for Win7 (xtool.exe) seems to fix this issue. Really strange.
Edit 3:
Ok no it's not fixed actually. After i arborted compression because of wrong lzma2, i fixed that and run again -> same problem as before.
Edit 4:
I've found the problem. If the pack data has folders + subfolders then xtool (or diskspan i dont know) stop working for some reason. But if i copy all files from all folders + subfolders into one single directory, then it works (it's the same size, but without any folders).
Edit 5:
My solution was now to just pick up some files and use your pack.bat from post #1, after it starts, wait some secs until xtool.exe starts working and then drag&drop game folder into diskspan bat and it works *facepalm* wtf
I think the problem here is xtool, because all other pre-/compressors working just fine with diskspan and whole game folders, but xtool doesn't. So?
