OS error - An operation failed because the disk was full

[wheeler498]

I am getting this error on multiple different Blu-ray. I have tried to 2 different local hard drives that both have over 150gb of free space?

Error 'OS error - An operation failed because the disk was full. If this is a thinly provisioned volume the physical storage backing this volume has been exhausted' occurred while writing data to 'F:/Video/Earth/Earth.mkv' at offset '6777995264'
Failed to save title 0 to file F:/Video/Earth_To_Echo/Earth_To_Echo_t00.mkv
0 titles saved, 1 failed

But your operating system is telling MakeMKV that whatever physical drive is mapped to F: is full. MakeMKV can't work around that.

One possibility - have you "deleted" files owned by the admin user recently, and NOT cleaned out your Recycle bin? That space is still in use, but "kind of free".
