So, I asked a question that could help me to understand what was happening. Your response has no relationship to the question and adds no useful information.
I asked a question because I was curious if the problem was just related to available free space, or to something else. The obvious something else was the size of the database on the device. And that is related to the number of books. It occurred to me that a sensible behaviour was to always reserve enough space on the device to rewrite the database. The device can't stop you copying books to it to fill the space, but it can stop creating files. There were also firmware versions in the past where the cover generation stopped because of the number of books on the device (to be accurate: number of books and length of file names). This could happen with a lot more than 100MB of free space.
But, I was curious enough to do some experiments. As I don't have enough books with me to fill my Glo HD, I used other files to fill it. The database is currently around 78MB, so left 50MB free on the device and deleted all the cover images for sideloaded books. And yes, the covers weren't recreated when I disconnected. So, I increased the free space to bout 85MB (enough for a copy of the database) and the covers weren't regenerated. Then I went to 125MB and the covers started appearing.
So, it appears you are right and having less than 100MB free space does prevent cover generation. There are some other things that stop happening with limited free space. That makes it appear they are trying to make sure there is always some free space to prevent the problems that a lack of space could cause. The obvious one is making sure the database can be updated at any time.

the amount of books on my aura filled to within 100MB of free space, would of course be around double of that on my touch, with the aura having 4GB while the touch only as 2GB.
that is why i didn't answer the question not because i was avoiding it, but because i was quite sure the amount of books on the devices was not causing the problem, but rather it was down to the lack of free space.
i always make sure i leave at least 110MB, and then everything works fine, thanks for looking into this i do appreciate it.
best wishes koboy
