If I format a Memory Stick from My Computer or Windows Explorer, it can't be used normally sometimes. Why is that so?

If you format a Memory Stick using the [Format] menu of My Computer or Windows Explorer, you cannot use it normally sometimes. You have to format the Memory Stick with a dedicated device or software.

--Attention--
To use the Memory Stick with a portable player or a digital still camera, please format it with the respective device. (The same applies to the MagicGate Memory Stick.)

Please refer to the procedure below to format a Memory Stick using [Memory Stick Formatter] of a VAIO computer.

--Procedure--
1) Click [Start] -> [Programs] -> [Memory Stick Utility] -> [Memory Stick Formatter]

2) The message [To format Magic Gate Memory Stick, a Memory Stick device supporting Magic Gate is necessary.] appears sometimes. Click the [OK] button and ignore the message.

3) Select a Memory Stick drive in Drive List of the [Memory Stick Formatter] window and click the [Start Format] button.

4) Format starts.
