I'm feeling ya, I'm getting utterly sick of this fucking dog shit way of managing disk's in the array as well, yeh nah, unraid can get in the fucking bin, I'm over it.
Clear a disk, format
Array says cant mount it needs to be formatted, so do so, disk unformattable, unmount, format, mount, make a folder and all working fine, do a pre-clear on the disk and start again.
Nup unraid says get fucked none of that is going to work in the array, do you want to format the drive? get fucked unmountable drive and unformattable drive.
You may get a sense of frustration due to the colourful language being employed here, however, fuck this utter dog shit
