"Cannot save because disk is full" but disk is not full [2015]

[Vcize]

I am working on a large 2gb tiff panorama.  I have saved it plenty of times before.  After doing some work today, I went to save it and I get an error "Cannot save file because disk is full".  The disk is very much not full.  There was 15gb of free space on the disk when I tried to save (now down to 6gb because each time I try and save it eats up 2gb that it does not release back when the error pops up), and my scratch disk has 60gb of free space as well.  What is going on here?

I don't want to exit out of the program as I've made quite a few changes to the file that I don't want to lose since I can't save.

Hi, in Photoshop, on the top menu bar, go to Help, System Info. You'll get a window with a lots of text, that you need to select, copy, and paste on this forum.

Photoshop is showing wrong values for my external disks.  They all have half a TB or more of freespace but it tells me those disks are full when I try to save a file back to source disk.  I have copied the sys info from photoshop and using Photoshop7

Unfortunately support for this old of a Photoshop version (7) ended a long time ago. I'm not sure why you have so many scratch volumes dedicated but perhaps isolating to just 1 or 2 and seeing if that resolves. I do recall seeing errors when the drives are TOO large for PS to calculate space - you have to remember back when this version came out a GB of space was considered large. I would remove these two from the list:

H:\, 2047.99 GB, 2047.99 GB free
