For Playstation Plus members who still show 150MB of cloud storage?
All you need to do is to open the Save Data Utility folder.
You will see the Save Data Icon with these numbers on the bottom ( ***MB/150MB).
Click to open this icon.
Let it repopulate your game save data. After this is done?
Simply back out of this menu and you should now see 1024MB.
Thanks to member slick690
for this info
Me too! I just found this and only this. No one else has posted anything according to Google. I tried everything from "PS3 Firmware 2.45 1GB still 150MB" to "PS3 Firmware 2.45 fail", to "PS+ 1GB not working", etc. Nothing else as of this moment. At least I know there's more. Hopefully an error of theirs. Some article said someone (forget who) from PlayStation said you'd have to have a valid $50 1-year PS+ subscription. Mine is that but will end in October. I should be good but why just for 1-year subscribers. Must be a mistake from the article. If not then DAFUQ?! Anyways, hope this gets fixed ASAP!
