Memory card parameter error is finding in my memory card.

Yes pentium 4 supports 4gb of ram..
older system supports 2gb of ram..
So you can increase your memory to your suitable choice.
While for agp graphics cards xfx radeon hd launched 4650 agp graphics card with gddr2 memory so you can purchase it for graphics card needing 1gb memory..
Please rate me on fixya if i am helpful..

throw it in dust bin , and purchase a new one..

if the cards work ok on something else then there's a issue within camera it could be the actual sd connector within the camera ? doess the camera support that size ? Optio E10 supports upto 1GB SD Card http://www.pentaxcanada.ca/pdf/o_manuals/om_OPTIOE10_e.pdf it might not work with the high speed sd cards ? Regards

Some camera's, especially older ones, have a limit as to the maximum size of the memory card that they support. Look in the manual to see what the camera can support.

If it is an SDHC card your camera is too old to support it.  You need to get an older-style SD card.

The problem is that the largest xD card that your camera can support is an M or H 512mb card. The 1gb card is not compatible. The firmware in the camera cannot support memory storage with that capacity. The camera came out before those cards did and there no plans to upgrade the camera to allow those types of cards to be supported.

its non supportive to 1gb card as you will have to get the device upgraded to make it support 1gb.

From DMC-FZ8 user manual:
[MEMORY CARD PARAMETER ERROR]
> Use a card compatible with this unit. (P19)
• You can only use an SDHC Memory Card if using cards with 4 GB or more capacity.

If you are convinced the problem is not your card, here's Panasonic's support number -800-211-PANA (7262). Hope this helps.

I have been rummaging around trying to find two solutions: 1) to get my Toshiba Satellite card reader to read SDHC cards and 2) to get my desktop USB ports to read SDHC cards. While MS offers a hotfix for XP, it does not always work because of the different Chip Sets in computers. I have also read where posters say that the SDHC card works in the compter NOW, but NOW will not work in the camera... and the SDHC card NOW works in the camera but will NOT work in the computer.... I found a tekkie article that may help clear the air... SDHC cards are formatted in Fat32x (NOTICE the "x") and SD cards are formatted in Fat32 (no 'x') and these compatibility problems arise when the user unwittingly or unknowingly RE-formats the SDHC card, either when it is put in the computer and won't read or when it is put in the camera and won't read... but just don't bother to mention that THAT is what they did upon inserting the card and only proceeded to complain about an apparent incompatibility. The camera or computer might even mislead you asking if you want to format the card..... but all is not lost. The Panasonic site gives a program AND a pdf instruction book on How To ReFormat an SD or SDHC card specifying the proper Fat32x or Fat32 format. Hope this helps.
