You can install a microSD memory card in your NOOK HD/HD+ to add up to 64 GB of memory to your NOOK—enough for many thousand more books, along with periodicals, music, and personal files.
microSD memory cards hold about 1,000 books per gigabyte. The number of periodicals you can store on your card depends on the size of the periodicals and the amount of storage on the card. Digital magazines and newspapers vary dramatically in size. Some highly interactive, photo-rich magazines can reach 1 GB each.
Books, periodicals, and other files stored on a microSD memory card appear in the My Files section of your Library.
To insert a memory card:
1. Lay your NOOK face up on a clean, level surface.
2. Find the small lid to the left of the 30-pin USB port on the bottom edge of your NOOK. Using your finger tip, gently pull out the lid.
3. With the tip of your finger, push the memory card in to the SD slot.
4. Push the lid back into place.
To remove a memory card:
1. Lay your NOOK face up on a clean, level surface.
2. Find the small lid to the left of the 30-pin USB port on the bottom edge of your NOOK. Using your finger tip, gently pull out the lid.
3. With the tip of your finger, push in the memory card, then release it. The card will pop partly out.
4. Slide the card the rest of the way out of the slot. Remove it, and push the lid back into place.
Types of Memory Cards Supported
Your NOOK works with three types of SD memory cards:
-
microSD™ card
-
microSDHC™ card
-
microSDXC card.
Your NOOK supports cards with the following specifications:
A microSDHC card with a storage capacity of up to 32 GB:
-
Class 6 microSDHC cards are supported. Class 6 is faster than class 4, which is faster than class 2. The class should be mentioned on the packaging for the microSDHC card and printed on the card itself. If no speed is indicated, the card is a class 2 card. The speed of the card does not affect page display speeds. It can affect read and write speeds when transferring books, periodicals, and personal files to and from the SD card.
-
If a card has been formatted with a FAT32 file system on a device other than a NOOK HD or NOOK HD+, your NOOK supports files as long as they are less than 4 GB.
A microSDXC card with a storage capacity of up to 64 GB:
-
On microSDXC cards, your NOOK supports the exFAT file system and can store files of any size up to the storage limit of the card.
-
The UHS speed for microSDXC cards is not supported.
When your NOOK formats a microSD card, it uses the exFAT file system, which supports unlimited file sizes. NOOK HD and NOOK HD+ eReaders can read exFAT memory cards, but other NOOK eReaders can read only memory cards formatted with the FAT32 file system.
