I HAVE SONYDSC-P72 WHILE UPGRADIND ITS MEMORY I USED MASAC-M2 WITH MICROSD OF 1GB BUT IT IS NOT MATCHING AND DISPLAYS AS MEMORY CARD ERROR

memory card do not match your phone.

make sure your'e mobile can map a 1GB. If not try another brand.

Once the message show like this
" Insert a disk or it is empty "
then your card is fail
now buy new card
also check error repair of drive

Yes, you will need an adapter unless you have a card reader that accepts that specific type of card.

this happens dude.

try to format it using a memory card reader on a computer, sometimes the card get corrupt

format it, it shld work fine, u can copy ur data also on the computer for a backup.

microSD card?
Sony cellphones don't use microSD, they use Sony memory stick micro (up to 4GB), Also called an "M2" card.

This may have something to do with how the m2 card is formated. PC systems such as FAT32 and NTFS do not work with cameras or telephones as the data cards in these devices are formatted to FAT16 or lower. In order to read the card when you placed it in your PC FAT32 would have been used.

If you are prepared to loose the data on the card I suggest you use a PC to re-format it to FAT16, your phone should then recognise it again!

Please format it. It needs to be formatted to read them.

Hi,

Try using.

You can add more storage memory for your device by using microSD cards. You can plug the microSD card into the slot provided on the player and then store your files on the card. If you had a 1GB player and added a 1GB card you've effectively doubled your memory. That's probably the memory upgrade you're thinking about.
