PUPMODE 07
The answer can be found here assuming that your stick is not formatted with a linux partition:

Extract:
- When Puppy is installed to hard drive in what we call "frugal" mode, we have the choice of saving the session to either a file or to the entire partition. The same thing holds for Puppy installed on a USB stick.
However, to save to the entire partition, it must be a Linux filesystem. It can't be done on a fat or ntfs partition.
Of course, saving session to a file has it's advantages, such as you can have lots of them and they are easy to backup. But, they do have a size limitation, I think of about 4GB although I have never tested that.
Saving to the entire partition is a kind of quasi-full-Linux-installation. You are using the entire partition to save your session, so you have available all the free space of that partition.
If you are using a linux partition on the stick you could try removing the fsck code.
