4GB Secure Digital High Capacity Memory Card: my 4gb sd memory card was not opening in any compu...

SD and SDHC cards have a slide switch along one edge. The position farthest from the metal contacts locks the card, protecting it from writes. The position nearest the contacts unlocks the card.

On your SD Card, there is a Lock switch. Turn the Lock off to unlock the memory card.

No.The SD is corrupted.But if you had a friend with a
pC with SD slot you can re-format the SD.

Your camera will accept a maximum SD card capacity of 2GB. It simply isn't capable of handling anything of a larger capacity and in particular is incompatible with the more technically advanced SDHC cards.

Your fix is to either replace your camera with a later model or to stick to using SD cards with a maximum 2GB capacity.

Try putting a tiny piece of scotch tape over the lock slider. See if that works.

Yes, i t should be unless it is a SDHC Card which it should not be as SDHC cards have minimum 4 GB capacity. For more info:

The older SD (secure digital) cards had a maximum capacity of 2GB. The SDHC (secure digital high capacity) cards can go to 32GB. Devices that support SDHC will say so in their specs and they will also read older SD card. Older devices that use SD cards will NOT use SDHC.

"SDHC (Secure Digital High-Capacity) cards are flash memory cards with a minimum capacity of 4GB (gigabytes). SDHC cards provide removable memory for compatible digital devices including cameras, camcorders, PDAs, MP3 players and more.

According to Samsung's page on this camera, the following memory can be used:

External Memory(Optional) : Micro SD (up to 4GB)
Micro SDHC (up to 8GB)

4 GB is acceptable, but I think you do not have the correct type of card. You should be using a Micro SD or "Micro Secure Digital" (up to 4GB capacity) or a Micro SDHC or "Micro Secure Digital High Capacity" (up to 8 GB capacity) card. This is very different from an SD or SDHC card. These Micro cards are very small (smaller than your thumbnail) and are often packaged with an SD adapter card. Regardless if sold with or with out the adapter, the package should say Micro SD or Micro SDHC on it somewhere.

you should try formatting the memory card to something different. because the same problem happend on my psp.

Do the 4GB Cards say SDHC on them? They should. SDHC is simply "Secure Digital High Capacity". They're high capacity SD cards that hold more than regular cards. In this case, 4GB. The problem with these is that they need to be supported by the device. I've never put an SDHC card into a device that doesn't support them, but it looks like that's what your situation is. The highest memory capacity a non-SDHC compliant device is capable of 2GB. I recommend that you return the 4GB cards and buy 2GB cards instead.

SD HC isn't comptible with that device. The best you can do is 2gb.

You can only use SD HC cards for devices approved for it.
