Some sections will be inaccessible to Jodi on your first play through, this means you will not be able to get some hard drives and collectables on your first run. There are currently four locations that are blocked off on the first play through, I will outline them below.
With the exception of the shower chase scene with the Devourer, you can backtrack to all other sections of the story mode. However, be careful not to drop down the hole at the bottom of the large stairwell if you have not left the elevator to B2 powered on, this will trap you on B2 and you will not be able to finish the game. Another soft lock are is on A1, there is a pit with three hanging Squirters, do not fall into this pit, you will have to load an earlier save as there is no way to get out.

Sealed Areas During First Run

1/4 A2 Corridor

At the very beginning of the game you will enter an office, once you proceed and leave this room there will be a shelf blocking the path to your right. This leads to the storage box where you can retrieve items from challenges and previous story runs. No items carry over from your first play through.

2/4 B2 Tunnels

In the lower tunnels you will get to an elevator on B2 where you can escape this area, opposite the elevator doors is a door blocked by a shelf, it contains the Wedding Veil and a Golden Skull Statue, you cannot get the Veil, but you can shoot the Skull.

A5 Lounge corridor

The highest floor you can take the elevator to is A5, however, this floor is completely blocked off for now. On this floor is a bedroom with a shower, this room contains a hard drive and the Wedding Dress (Once all hard drives are collected). Beyond the lounge is a second combat room, where if you survive all waves you unlock a door that leads to a back office and a hard drive.

A1 Elevator corridor

Similar to A5, if you take the elevator to A1 the floor is almost immediately sealed off. This corridor leads to several traps and a clothing item. Be careful not to fall into the pit, there is no way out.

The list may not be complete, as there was no reward for finding them all, I also feel there was a large section of the level that had no audio files. If you notice any I have missed or not found, please let me know and I will update.
The audio files are much easier to find compared to the other collectables, I believe this is because they help to expand the story.
