The following alert appears, "Unable to use card. Format?".

I experienced the same problem (my USB device ). try these steps:
1. Start, Control Panel,
2. Performance and Maintenance,
3. Administrative Tools,
4. Computer Management,
5. Disk Management,
6. Find the USB drive (usually the last storage device before the optical drive),
7. Click on the USB drive,
8. Right click on it and you will see the options (New Partition or Format)
9. Follow the instruction (I chose FAT32), but please do NOT chose Quick Format.

Card error means the camera wants you to format the card in the camera, not the computer.

From the Home screen of the BlackBerry smartphone, click Options > Media Card or Options > Advanced Options > Media Card.
Display the menu and click Format Card.

• some times Format Card option does not appear on the menu, skip the step and perform the procedure that follows.
• A warning message will appear asking if you are certain you would like to format the card. Click Yes to continue.
  If the Format Card option does not appear on the menu, complete the following steps:
• On the Media Card screen, set the Mass Storage Mode Support field to Off.
  
• Display the menu and click Save. The Media Card screen closes automatically.
  
• Click Media Card to reopen the Media Card screen.
  To format the media card, display the menu and click Format Card.
  
• A warning message will appear asking if you are certain you would like to format the card. Click Yes to continue.

It seems that the card is bad. Try to format the card on a different machine to rule out your Windows formatter.

it means that the memory card's sector is damaged by a virus infection...try to delete the files while in the mobile and then format it..if it agains appear the same then you've to buy a new card only

THIS PROBLEM SEEMS TO NOT UR DRIVE BUT
1. WITH UR SOFTWARE OR
2. THE DISK U R USING

MAX TIMES THE DISK CAN NOT FORMAT SO 1st TRY TO CHANGE THE DISK
I THINK THIS WORKS

Hi Eric :)
Please try formatting the Memory card using your computer first in the following manner:
>> Insert the memory card into memory card slot / memory card reader
>> Check the drive letter that it has been assigned by the computer
>> Right click on the drive and select Format option
>> Now this is very important.. Select FAT file system from the drop down options (DO NOT select FAT32).
>> Now Format the card and then try formatting the same card in Camera.
Let me know if that works for you.

You mentioned in your post "the above camera", but I can't find the make/model of your camera? Check on the manufacturer's website to see what the largest capacity card can be used in your camera. Knowing the make/model and searching for the message on the internet can yield better answers to your question.

Ok. Don't mark me down for this answer because it seems you are at the end of the rope. This is what I got off the Konica support site. Question- How long does it take to reset date after the batteries are removed? A rechargable battery cell is built in the DiMAGE A200 for date/time backup. However, in case the camera is left for a long period of time, the camera is not able to keep the date/time setting if the dedicated battery has been removed before storage. If the date and time was reset, it is necessary to set them again. An internal battery is charged from the camera battery, and fully charged for approx. 30 hours. An internal battery protects the settings for approx. 240 hours (approx. 10 days) if it is fully charged. NewMediaMan- So, you'd have to leave the camera without the battery, for a long time to reset it. Konica Support site: Question- Unable to use card. Format?' alert appears. Answer: The following conditions are presumed: - File system of the card was changed by formatting with PC. - The card was formatted with other memory card device. Basically we recommend the users to format by using the camera. (All the data in the memory card will be erased.) As the memory card may have defects in itself, please try other memory card, if you have other memory cards. My solution(s) Step 1. You could try taking the camera into a Best Buy or someplace like that and ask if they have a spare card you could try in your camera. Perhaps they have a demo camera that they could swap out the card. It wouldn't hurt to try that first. Step 2. If possbile, leave the camera without the battery for about 2 weeks to see if it will reset the internal components. It's a free fix. Step 3. Purchase a new CF card and see what it does. And I need a good rating so please be kind. Thanks. Rob NewMediaMan
