Problem accessing removable disk

When the card worked before, check if you did not switch the lock switch down. And check all contacts on the card and in the camera. They should be clean and shiny.
When you recently bought a new card you could have bough a SDHC card and these won't work in your S800.
The S800 only accepts MMC and SD cards, The SDHC and SDXC cards won't work.
A few years ago you still could buy 4 Gbyte SD cards. Now even most 1 Gbyte and 2 Gbyte cards are already SDHC. SDHC was introduced at least 7 or 8 years ago, so all new devices accept SDHC. The SDXC was introduced at least 4 years ago, so in a couple of years, you perhaps only can buy these cards?

Do you really need the Samsung software?

The best way to download pictures from your camera to your computer involves removing the memory card from the camera and plugging it into a card reader (either built-in to the computer or connected via USB or FireWire). This is likely to be faster than connecting the camera to the computer, and won't run down your camera's batteries.

Once the card is plugged in, it will appear to your computer as a removable drive. You can use the operating system's drag&drop facility to copy pictures from the card to the computer's hard drive, the same way you copy any other files. Or you can use any photo cataloging program such as Picasa ( http://picasa.google.com ).

THis model isnt compatible with Win 7, then I suggest removing this card and using it directly into a card reader in your computer to have access at pictures. If you have the correct reader installed in your computer already then just insert the card into the reader and then if the card does not show up, just look for it in your start menu under "computer". It will be visible under the "removable storage" devices in the menu.

If you do not have a card reader installed in your computer, you can purchase a card reader for your specific card, they are readily available and do not cost very much.

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day

Probably, especially if your card is a 4GB or larger SDHC card, then it's definitely the wrong card. The older Digimax S800 camera can only use standard SD cards (2GB or less). Fortunately, these are very inexpensive these days, and may be found on Amazon if your local store no longer carries them.For others reading this experiencing similar problems, please see this article.

From page 63 in the manual.

Wow! You have 400 pics on the internal memory. That must be some huge internal memory. Anyway, to delete them, remove the card from the camera...go into the menu and find "format"...follow the on-screen instructions.

As per the Samsung digimax range, internal memory seems to be faulty. Insert an external memory card and try to power up the camera.....

If it isn't too far out of your means, I don't use the software for my camera. I use a card reader. You can find a card reader for about $10 - $15 in most stores that will read 7 or more types of cards. I use my own photo software. Only accessed the disk for the pdf manual. My laptop has a built in card reader. You may be able to find a solution by letting your computer search for a driver on Microsofts site. Mine was automatically recognized on win xp. Hope this helps.

the samsung digimax 4010 camera supports up to 512 Mb cards. 2gb is too big

i am using 2gb card
