#1
Insert your memory card into your computer's reader if you have one. If not, you can purchase a multi-format USB Memory Card reader from Amazon.com or Buy.com
#2
Open up 'My Computer'. You should see it under the list of available drives.
#3
Check its contents first to make sure that you have the right drive.
#4
In 'My Computer', right-click on the drive and choose 'Format'.
#5
Leave all the options as they are and click on 'Start'. This is a non-reversible process so make sure this is what you truly wanted to do in the first place.
#6
Once the process is completed, take the memory card out and insert it into your Digital Camera or any other device. Try to browse to it to make sure it works fine now.

With A USB , CELLPHONE , Camera The SameThing

If you normally upload your pictures by connecting via the USB port, remove the memory stick before connecting the camera to the computer. If you normally upload your pictures by putting the memory stick into a card reader, use the camera's memory stick tool to copy the pictures from internal memory to memory stick.

Please take out memory stick from camera and power up camera and check still gives format error?
If no further error then put memory stick back in camera and press Menu >> Format >> OK to format memory stick. That will delete all data on memory stick and refresh it for new photos.

If Duo Pro got hardware problem, then it can not be fixed and you can't retieve data on it. Regarding new memory stick, camera will check it and let you know about format it or not.

Memory stick can be defective. Use an other memory stick to confirm the camera. Do not use more then 1GB memory stick in this model.

I got a msx-8mgs of sony memory stick duo
how to format?

Format the memory stick via setup menu inside the camera. Let me know if this works.

i think this problem arises when you fail to regularly format the card ie. take lots of pictures and delete some and repeat the process over and over instead of downloading every session and formatting the card causing coruption. Also if you've bought pro duo memory stick off ebay poss. its a very good forgery (again i've been caught out by this).
