F1-9 : Milliseconds to Spare was the first F level I could find that didn't completely rely on a second time field to obtain the storage device.
As a rough text guide
1. Knock the first Yellow and Black Bridge down and jump over the gap.
2. Press Y, walk left and press Y again at the opening. Now press X. (also you could just jump over the wall and jump again to land on the floor, whichever is easier for you.. same thing)
3. Walk left down the small opening and land on the ground by pressing right slightly to avoid the laser.
4. Position yourself between to the left of the right laser and to the right of the second (currently open) bridge.
Step 5 is a quick process:
5. Press Y and quickly walk left into the hole as the bridge starts coming down. Quickly Press B after going through the hole to avoid falling to you death..
6. Walk all the way to the right so that the small hole is to your right. Press B.
Step 7 is a quick process:
7. Walk right into the hole and hold right as you fall. The moment you fall through the hole, press B. May take a few tries to get this right as its fairly easy to die on this step. Repeat until success.
8. When you land, press X and grab the Storage Device.
Best of luck to you for the rest of the game. Its fun so far.
