When I inserted SD Card ( kingston 4 gb) into Trust 760 PowerCam CCD Digital Camera LCD screen is black. Card is not read. When I inserted SD Card ( 128 MB ) into Trust 760 PowerCam CCD Digital Camera LCD screen is on. Card is read.

Your 2 Gb is not just an SD card, it is a SDHC card. The first 2Gb SD cards, still were SD, but 2Gb was the limit for the FAT 16 and 32 format and for the normal SD cards. The same happened with the hard disks. They developed the SDHC card, and made the new hardware downward compatible with the old SD cards. So in a new camera, you can insert SDXC, SDHC, SD and even MMC cards. But the cameras, card readers and phones, who were made for SD, can't use the SDHC or SDXC cards.
SDHC can work with memories up to 32 Gb and from that on, it is SDXC.
There still should be some 2Gb SD cards around, but not sure you still can fine one. The producers of memory cards now only make SDHC cards and up. Perhaps you only can get some 1Gb cards as SD card, but perhaps nobody will ever make these cards anymore.

I mannaged to buy a 4 GB SD card a few years ago, but that was the last I ever saw in the capacity.

put it in a computer and see what it reads,it might need formatting .

The HP Photosmart 320 camera is too old to accept a 2 GB card. It can only handle an SD memory card up to 128 MB. (The detailed specs for the camera are available from HP here: http://h10025.www1.hp.com/ewfrf/wc/document?docname=buy60403&tmp_task=prodinfoCategory&cc=us&dlc=en&lc=en&product=75944 or refer to the User Manual, also available from HP's support site for the Photosmart 320. The information is on page 61 (page 63 of the pdf).) Amazon lists a Kingston 128MB card for ~$9 here: http://www.amazon.com/Kingston-128-Digital-SD-Package/dp/B00006BBY4 .

I hope this helps and I wish that I had better news for you.

The internal memory for this camera is 8 MB.

The manual indicates using memory cards of size 8 to 128 MB, so this is an early SD memory camera, following the original SD standard. Do not try SDHC or SDXC cards. The camera will support a 1 GB card. It *might* support a 2 or 4 GB card, but since this is a 2 Mpixel camera, a 512 MB or 1 GB card will allow you to save thousands of jpeg format pictures.

You need to get rid of the pictures in the internal memory. If you want to save any of them, go into the menu and find "copy". You will find the option to copy them to a memory card. Then, with no card in the camera, go into the menu and find "format"....follow the on-screen instructions to erase the internal memory. Then your card should work properly.

The 5900 uses SD cards. The 4GB card you have is actually an SDHC card and will not work in the 5900. You'll have to stay with cards 2GB and smaller.

Hi,

The manual lists the following SD cards compatible:

4 GB SDHC Memory Card
2 GB SD Memory Card
1 GB SD Memory Card
512 MB SD Memory Card
256 MB SD Memory Card
128 MB SD Memory Card
64 MB SD Memory Card

An 8GB card may or may not work. If you try it, make sure it is an SDHC card. (Note: HC=High Capacity)

Thanks for using Fixya.

1) Have you formatted the cards?

2) Try the cards in the card reader in your computer to see if they can be read.

3) Try the "switch off camera - remove and replace battery - switch on camera" trick with the original 128 Mb card in place. This will reset the camera's memory.

4) Note the type of card is important - not all cards can be used in a camera (especially some of the latest bigger ones) - check the type of cards supported by your camera.

I found this at the Nikon USA site (note that the 2 GB card is not listed - as said "Cards are not all the same" and use different drivers to operate them):

Question Which Secure Digital Cards are approved for use in the Coolpix 4600/5600? Answer The Nikon Quality Department has tested the following cards and approved their use in the Coolpix 4600/5600:

SD memory cards:
SanDisk 16 MB, 32 MB, 64 MB, 128 MB, 256 MB, 256 MB*, 512 MB, 512MB*, 1 GB
Panasonic 16 MB, 32 MB, 64 MB, 128 MB, 256 MB*, 512 MB*,1 GB
Toshiba 16 MB, 32 MB, 64 MB, 128 MB, 128 MB*, 256 MB, 256 MB*, 512 MB

*High speed type of 10 MB/s or over

Other brands and capacities of cards may work, but Nikon cannot guarantee their operation. Check with the manufacturer of the third-
party card for compatibility information. Nikon recommends keeping one of the approved cards available for troubleshooting.
