I just got the little Argus DC 5195 camera and bought a 4gb SDHC card but it does not work with new card. I cant even format it, what else can I do??

None. The DC-5195 works with SD cards, which max out at 2GB. It will not work with higher capacity SDHC cards.

The DC-1020 works with SD cards up to 2GB in size, not SDHC cards 4GB and larger. The same limitations apply to microSD and microSDHC cards used with adapters. The adapter will make a microSDHC card appear as an SDHC card to the camera.

You need to use SD or microSD cards, 2GB and smaller.

The problem is that your camera is only compatible with SD cards, not SDHC cards. You bought a larger card for your older camera, not noticing that it was SDHC (or not knowing that it mattered). The new card doesn't work, not because it or the camera is broken, but because it's not compatible.

Cards up to 2Gb are generally SD.
Cards of 4Gb are generally SDHC.
Cards over 8Gb have to be SDHC.

(There are exceptions. Sometimes, manufacturers make 4Gb SDHC cards but some have errors; they disable half of the chip and sell it as 2Gb, but it's still SDHC. 4Gb cards are almost always SDHC because they're cheaper, but 4Gb SD cards do exist. They are so rare that I've even seen a guru on this site claim they don't. I did own one once, but it was very expensive and turned out to be so unreliable that I had to return it. I don't recommend looking for one, because of the problems.)

Your solution is to go find a 2Gb card, and be extra sure that it doesn't say "SDHC" on it.

Well, the error literally tells you to format the card. The format function should be in your settings menu. Before you do this, make sure that you've copied all you want off the card and then use the camera's 'format' function to reformat the card. I advise using the camera for the format function because this guarantees the correct file system. If you use your computer to format it, you may easily get the wrong one. However if you need to do it this way, see which file system is currently in use on the drive before you start. Go to "My Computer" and right click on the drive which is the memory card, and choose "Properties". Examples of filesystems are "FAT" (probably FAT16), "FAT32" and NTFS; to make sure your reformat is successful, ensure you use the same filesystem as before.

If this fails, the other possibility is that you've bought an SDHC card and fitted it to a camera that can only accept SD. In this case you bought a larger card for your older camera, not noticing that it was SDHC (or not knowing that it mattered). The new card doesn't work, not because it or the camera is broken, but because it's not compatible.

There are several possible causes for "memory card locked", "memory card error", or "no memory card". Some include trying to use of a 4GB SDHC card with an older camera made before SDHC format came out. Others include problems with the tiny slide switch on the side of the card, or the electrical contact switch internal to the camera. The problem may also arise from simple formatting problems if the card has never been formatted in the camera (note that this will also erase the card). Troubleshooting tips for this problem may be found at this link.

1. Try to format your memory card using a PC/Laptop.

2. Now, insert it in camera and check whether its working!

please rate this advice if it helps....tc! :)

I'm guessing you bought a new 4GB SDHC card. Although it looks exactly the same as a standard SD card, the format the card uses is very different. Unfortunately your camera was designed before the SDHC format came out. Sorry, but a SDHC card will not work with your camera.

You'll need to use standard SD cards (usually those 2GB or less). But if you really want to use a 4GB card, do a Google search for 4GB SD "non HC", with the non HC in quotes. Believe Transcend makes one.
