This message will appear if the device is formatted in FAT. The maximum number of viewable files and folders in the root directory has been reached.
To store more data, you need to delete one file, create a new folder, and then transfer about half of files into this new folder.
Or reformat your device to FAT32 file system.

- Try again with another card reader under Windows.
- Under My Computer, right-click the card's removable disk icon and select
   Properties > Tools, under Error-checking, click Check Now.

Many digital cameras only support FAT file system.
Reformat your memory card using FAT.

"X" speed is a performance indicator. The device measures throughput using read/write values in MB/sec.

Throughput refers to the amount of data that can be transferred to/from the host to the device.

To determine the actual MB per second, multiply the value of "X" by 150 KB/sec.

For example:
Value of X = 150 KB/sec.
133X = 133(multiplier) x 150KB/sec = 20 MB/sec

Flash memory devices are typically measured and labeled in 3 ways.

1. Throughput refers to the amount of data that a device can transfer to/from the host in a given time period.
       A device measures throughput using read/write values in MB/sec.
2. A device may be measured using the "X" factor.
       - Value of X = 150 KB per second
       - A value of 60X = 60(multiplier) * 150KB/sec = 9.0 MB/sec
3. A device may also be measured using Class 2, Class 4, or Class 6 (applies to SD card only).
       The SD Speed Class Ratings specify a minimum sustained write speed for SD/SDHC cards
       (Class 2: 2 MB/s; Class 4: 4 MB/s; Class 6: 6 MB/s).
   
   NOTE: Performance may vary based upon host device.

SDHC (also known as SD 2.0) is the latest Secure Digital Card format that is FAT32-compliant.
SDHC cards are designed to support capacity from 4 GB to 32 GB.

SDHC cards are divided into 3 speed classes, which guarantee a minimum transfer speed:
- Class 2 (2MB/sec)
- Class 4 (4MB/sec)
- Class 6 (6MB/sec)

SDHC cards will ONLY be recognized by devices that support the SDHC formats.

Devices that support the SDHC are backward compatible with type SD 1.0 and SD 1.1.

1. Make sure the devices can fully support the memory card.
2. Format the memory card with your mobile devices.

The issue is caused by a 4 GB file size restriction for FAT32 file system.
To resolve this issue, reformat your device as NTFS.

1. Backup all your data
2. Open Windows Explorer
3. Click My Computer
4. Right-click the drive letter representing your memory card
    and select Format
5. Under File system, select NTFS.
6. Click Start.

WARNING: Formatting a product in NTFS will make it unable to be written to on a Mac computer.
Most Mac computers can read NTFS, but not write.

All memory cards are pre-formatted. If you need reformat it, follow these steps:

WARNING: REMEMBER TO BACKUP ALL YOUR DATA BEFORE FORMATTING!

1. Double-click My Computer
2. Right-click the drive letter representing your memory card
   
   WARNING: BE SURE YOU SELECT THE CORRECT DRIVE LETTER!
   
   
3. Select Format
4. Select a file system type
5. Click Start.
   
   Note: The Windows XP format utility used for memory cards with capacity of 64 MB and higher defaults to FAT32.
   
   Many cameras and portable devices do not work with if the card is formatted as FAT32 or NTFS file system.
   One of the following errors may occur if your device does not support FAT32 or NTFS:
   
   - Error message asking to re-format the flash card.
   - Error message that the flash card is not formatted.
   - Error message indicating that the card is anomalous.
   
   To resolve the above error, backup your data and reformat your memory card with FAT16 file system.
   
   If the error persists, re-format the memory card using your camera or portable device.

WARNING: Formatting will erase all data on the device.
Back up all your data before proceeding.

NOTE: When using a memory card, it is recommended to reformat the card in the camera, MP3 player, or other devices that you are using it with, instead of formatting it through your computer.

To format a device on your MAC OS X:
1. Double-click on Macintosh HD.
2. Click the Applications folder.
3. Click the Utilities folder.
4. Double-click on Disk Utility.
5. On the left side of the window are the drives connected to the computer.
    Select the capacity of the drive respective to the one containing the device you wish to format then click the Erase tab.

    Example: If the drive is called "NO NAME", directly above that, you should see the drive capacity of "XXXX". Select this capacity.

6. Verify Volume Format is set to MS-DOS file system, then click Erase. This should reinitialize the disk.

If your SDHC™ card capacity is 4 GB or higher, contact the camera manufacturer to verify that your camera supports SDHC.
Not all cameras support SDHC cards.

If your SDHC™ card capacity is 2 GB and below, format your SD card using your camera.
For instruction on how to format the card using your camera, refer to the camera user's manual.

Some data on your card may be corrupted by abrupt power loss.

Formatting the card should fix data corruption problems.

Do not format the card using the NTFS file system.
