Sdhc unable to format write protected

My 4gb memory card SD showing 30.1mb and can't formatted it{Transcend}

Hello Sean,

Please try to format the SD card using the SD Formatter 3.0 for SD/SDHC/SDXC. The software formats all SD memory cards, SDHC memory cards.

Download the software from the link provided below :

trurn off write protection

On the side of the SDHC memory card is a sliding lock I have a diagram to show where this is and which direction to push the slider. Here is the diagram.

Also to make the SDHC work compatible with your camera you need to format the memory card. Each time you download the picture files the memory card needs to be formatted, never format in the computer and expect the card to work in the camera.

SD and SDHC cards fit the same slots, but many cameras won't work with the SDHC (high capacity) cards. SDHC is not backwards compatible.

There are several possible causes for "memory card locked / write protected", "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 switch on the side of the card, or the 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.

The problem is that you're using an incompatible memory card.

Your camera is designed to use SD memory cards up to a maximum 2GB capacity. Click on this link for the user manual and look at the specification on page 43 under the heading "storage".

You're trying to use an 8GB SDHC: not only is the capacity far too large for your camera to handle, but it's a later technical standard which your camera does not have the hardware for. SD and SDHC cards may look the same, but are very different "under the skin". SDHC compliant devices are backwards compatible with earlier SD cards, but SD devices like your camera cannot be updated to use SDHC cards.

Your only fix is to replace the SDHC card with an SD card of no greater than 2GB capacity.

Please take a moment to rate my answer.

Memory card support for Z1285: SD/MMC up to 2 Gigabyte and SDHC up to 8 Gigabyte.

There is no firmware available online for this model.

The last option could be that the lever on the SD card is making the SD card data protected. Please turn the lever to the correct side.

I hope it works out

Far too often these little things have an almost invisible read/write protect button on them. Look carefully, over the entire surface of the USB Flash Drive. You might have this switch turned to Write Protect, which means there is nothing you can do, until you turn it the other way, and allow the device to be written to.

Cheers!

For some reason, the SD card in your camera is being viewed as write protected. There is a small "switch" on the SD card that slides. Slide it up and down a few times and try it again. If that does not work, here is the solution that worked for my camera. Place masking tape (opaque, used for painting) over both positions of the switch. I had to put 2 pieces to make it inflexible. Be sure not to get tape on the metal contact points. I hope this works for you. It fixed mine, although I don't really understand why. If this doesn't work, try a new card.
