Can't access data on storage drive

Have you tried clearing games data?

Deleting Saved Game Data

Game saves, player profiles, and other game data is automatically saved to the Xbox One hard drive by default. If you suspect that data is corrupt, you can delete it from your hard drive.

Please note: Deleting saved game data is permanent and cannot be undone. Therefore, it is highly recommended that you back up your saved game data to online storage or a USB storage device before deleting it.

Follow these steps to access the System Storage and delete game data:

From Xbox Home, go to Settings.

Go to System and select Storage.

Select Manage storage on the right-hand side of the screen, then select View contents.

Highlight a game, press the Menu button, and select Manage game.

Select Saved data on the left-hand side of the screen.

Choose a game to access the game’s saved data.

From here, use the Options Menu to delete files or to view more information about a specific file.

You can't increase the amount of cloud space. The cloud on the 360 is only for game save data, not game data. It sounds like you need more storage space for the game itself. You would either need an Xbox hard drive or you can use a flash drive or external
USB hard drive.

Hey, you can recover all the data from it. Just follow this tutorial which exactly explains to you what you need to do now -

Unfortunately this can happen sometimes with flash drives. When this happens there is no way to retrieve the data.

To prevent this from happening in the future please format the drive on your pc before using it on the console.

Try to make sure that it is the correct hard drive, if the hard drive is broken, being able to recover your data will be quite difficult, unless if you had used cloud storage, and if you used cloud storage, then you will be able to carry the data over to
your new console/hard drive.
