Went from Mavericks to Sierra on Mini late 2012.
I've noticed since then that formatting new hdd's, Disk Utility is always coming up with some kind of error messages or fail to format.

For example, last summer I bought some new Seagate's and I couldn't get them to format. I had no problems giving it a go on my MacBook with Snow Leopard on it. I had no issues when the Mini had Mavericks.

After searching web, I had to resort to connecting the drives to my pc laptop and do some diskpart1 voodoo in the terminal to get rid of that invisible little partition thing thats on these drives. I don't know much about these technical things, but maybe its the EFI partition or something? I don't know. All I know that apparently whatever it is is what gave me formatting errors trying to Mac format those drives. After the voodoo, I could.

Again today. I got a 16gb usb stick I wanted to Mac format..... I need to interject here....since I'm wary of whether or not disk utility properly formats, I may do it twice..... cuz I'm OCD about it now. What I find happens is that on the first shot at formatting, it works. But every time I do it again, it gives me an error message, or fails.
When this happens, the disk(s) unmount themselves

So I go and try to format it on my pc to exFAT. Except now, that's telling me I got only 200mb's outta the 16gbs that can be formatted!! Apparently this is common issue and I found another 'diskpart' terminal voodoo thing to restore the stick to format back to its full size.

So here's my question. Is it just me or has, since the last several OS X versions, that just performing the simple task of properly formatting a disk has become a major PITA?

I mean, in the 'old' days, I'd buy hard drives and format them. For years and years since my first Mac in '97....NEVER A PROBLEM....till I started using Sierra
