Memory Sticks and MAC

[jota73]

Hello Guys!

I won a SONY DSC P200, I have two memory sticks (lexar of 128MB). I need some help.

I have taken some photos and when downloading them to my intel mac via an accesory that has all media slots, everything seem ok, but when I delete all of the photos from the memory stick and insert this again into the camera I get a message that says NO MEMORY SPACE even though it is empty (no photos). That memory stick has not worked ever since then.
So I took out the other one, and when downloading the photos decided to do this through my HP Photosmart C4180 media slots.... same thing happened....
None of the memory sticks work now... both when inserted in the camera says NO MEMORY SPACE.

What is going on? Does the memory stick must have a MAC FORMAT? If so, how do I format them?

What can I do? Are the memory sticks damaged?

PLEASE HELP!

Juan

You need to Empty Trash before ejecting the memory stick.

It's best practice to format the stick once it's back in the camera. ;)

Don't delete files from camera memory cards or format them from a computer.
Do it with the camera.
In your case - do a reformat on the cards in your camera to restore them to good graces.
