How to Format Your Tab 4 NOOK’s microSDHC Card

By Corey Sandler

When you buy a new microSDHC, it will likely come formatted (a process that electronically indexes its memory so that the computer inside your tablet knows where to store or retrieve information). In that case, it’s ready to use.

If you insert an unformatted microSDHC card, the Galaxy Tab 4 NOOK will alert you. No biggie. To format a microSD memory card when the system asks, follow these steps:

  1. Tap the Format Now icon.

    You’re asked if you are sure. Sure you’re sure!

  2. Tap Format Now.

If you want to completely wipe the contents of the card, manually format it. You might be clearing the card to give it to someone else, or perhaps installing a used card from another person. Or you might want to remove all traces of a top secret missile launch protocol sent to you as a gag by your daughter’s teenage hacker boyfriend.

Here’s how to start manual formatting:

  1. Swipe down from the top of the Home screen.

  2. Tap the Settings (gear) icon.

  3. Choose General, then Storage.

  4. Slide the right panel up to reveal the options under SD Card.

  5. Tap Format SD Card.

    You’re asked if you really want to do this. Stop and think whether you really do.

  6. Tap Format SD Card again.

  7. Tap Delete All.

Formatting a microSDHC card permanently deletes all data and any apps that are stored on it. Some service bureaus may be able to recover data from a formatted or erased card, but you don’t want to rely on their less-than-certain capability.
