SOURCE: Message: Memory Card Error - Memory Card Parameter Error on 4gb SDHC card

I recently bought a DMC-TZ3 and have been researching memory cards. Several sites sell cards with the camera and list the card type. I would suggest buying one of these cards. Any cards larger than 2gb must be SDHC type SD cards. There appear to different types of SDHC cards, 1.0, 1.1 and 2.0. Check out Wikipedia.org for a description. 2.0 cards are not compatable for devices developed prior to 2.0 so that may be the reason for the camera problem. So far I haven't seen anything that states what type SDHC card the camera requires. I found a computer memory site that that sells memory that they say will work. There may be others.

I found a user manual online says max memory is 256mb on this camera. Wont recognize anything bigger.

Here's the manual in pdf

Basically picture files in memory card have corrupt data that's why computer doesn't recognize it.
HP recommends following action...
Close the HP Image Zone or HP Photosmart Software, disconnect the camera from the computer, and reset the camera. (can see this at HP Support)
2nd option is to find some memory card data recovery software on internet and use it to correct data files in memory card.
Thank you.

Try to open the files with a computer. Then try formatting it. For that
1. Click Start->Run
2. Type CMD in RUN
3. Then the DOS prompt will appear.then give the command for formatting......ie,
c:/>format H: /fs:fat32
*where c:/> is 'C' prompt
H: is Memory Card drive letter
FAT32 is file system

SOURCE: xD card says needs format, don't want to erase my pics!

Try to use the recovery softwares, the most I use are these, they are paid but are very very Efficient.
1) Active Undelete
2) Diskeeper Undelete
If you want some free ones, google it, you will find many but with not a good success rate.
And make one thing clear, as many times as you will use (Insert, Plugin, Plugout, Read, Write...) the Card, the efficiency Rate will be down and down for getting the healthy files.
If I was helpful, kindly do Rate!
