Card not initialized? how do I initialise this?

Try to initialise (format) it in your computer. Use an external card reader. I think you should use FAT 16 or FAT 32. But once the Roland sees the card, do an initialise there.
It could be the Roland can;t work with memory cards above 2 Gbyte, for that try to make a 1 Gbyte partition in your computer and again try if it works.

Not sure what you mean here. Have you already initialised the card and lost photos or do you want to initialise it without losing pictures already on it?
If it's the first part you need to use some recovery software to get your pictures back.
If its the second - you can't. Initialising a card will wipe the photos - and then you are back at 1 and will have to use some recovery software.
The only way you can do it is to copy all the photos off the card first - then it doesn'r matter.
Alternatively - buy another card.

You can't. Initializing (formatting) your memory card will erase the card. But formatting the card with your camera is a necessary step to either rejuvenate the card, or minimize later file error problems that will crop up if you don't do such. Backup/download the photos that are on the card to your computer before initializing.

Download any pics from the card using a card reader if necessary. Then, go into the menu and find "format" or "Initialize" and follow the on-screen instructions.

Go into the menu and find "format"(might be called "initialize")...follow the on-screen instructions.

You need to download the pics to your computer using a card reader. Then, format the card in the camera to completely erase and initialize it.

If the pics are safely downloaded, format the card in the camera to initialize it.

initialise(format)

1. press < or > to sellcet ok
2. pressing the MENU/OK button erases all the frames(files) and initialises the picture card
   

Same answer I just gave to someone else. The first thing to do is to try to copy any data that is already on the card before you put it back into the camera and initialize it! Otherwise you will lose every photo on the card!

Once you are sure that you have copies of the photos, or that there is nothing in there that you can recover, put it back into the camera, go into the camera's menu, and select format or initialize, and let it do its thing.

Another solution would be to put that card aside in case you can later recover the images from it, and buy a new card to use in the camera. This holiday season you can get a one or two gig card for nearly nothing!
