Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

OK, I have moved some stuff off sdc1, Linux now says there is 139.8GB free - but Windoze still says there is zero space, and SO DOES pMount AND sudo df -h

PartView gives me the 139.8GB free information.

Mint reports 86GB free on sdc1 now vs 18.6GB in the image above.
VERY strange.

I will continue to remove data from this drive till it is empty, then I will see if Windows etc are STILL reporting zero available. At that point, I will then reformat the drive and copy SOME stuff back to it, and see if Windoze etc is then reporting a more believable figure. I will keep the copy I make of sdc1, in case this drive is failing or something.

I've never seen this before. Normally, the Linux volumes just report correctly, so this is a totally new head-scratcher moment for me.

A web search for
linux file system reserved space

shows 5% is reserved by default for root.
(Whether yours is 5% I don't know.)

You can release it using tune2fs apparently.

Or show its setting using
tune2fs -l /dev/sdc1
(you'll need sudo in front of that if you're not root)
