I think this was posted before but i figured i put it in again because i could not find the topic.

When looking through all personal storage's you do not see items you own that are in gamma bases that your corp does not own.

if you go to that terminal the items will be there but if you are not in that terminal you cannot see those items.

Likewise corp hangers in other gamma terminals (not owned by own corp) show the hanger, hanger name and its contents through the corporation window but the terminal name does not show. so there is no way to tell where those items are if the storage folder is named something like level 1 storage.
