My camera tells me it's full when it shouldn't be. I have a 2gb sony memory stick pro duo for my Sony Alpha 100 camera. Today, I shot about 80 photos and it said it was full, but I had just deleted all the other pictures.

Quoted from the technical specifications available on the Sony website UK. http://www.sony.co.uk/electronics/cyber-shot-compact-cameras/dsc-h300/specifications Storage Media Internal MemoryApprox.55MB Compatible Recording MediaMemory Stick Duo, Memory Stick PRO Duo, Memory Stick PRO Duo (High Speed), Memory Stick PROHG Duo, Memory Stick Micro*10 , Memory Stick Micro (Mark2)*10 , Memory Stick XC-HG Duo, SD Memory Card, SDHC Memory Card, SDXC Memory Card, microSD Memory Card*10 , microSDHC Memory Card*10 , microSDXC Memory Card*10

The DSC-H2 works with Memory Stick Duos, not with Memory Stick PRO Duos.

You can use Memory Stick standard, pro or pro duo up to 2GB with the Camera.

A dedicated adapter (MSAC-M2) must be attached to use Memory Stick Duo™ or MagicGate Memory Stick Duo media.

I have provided the Memory Stick compatibility chart for your reference.

Problem for Sony Memory Stick PRO Duo (2GB) for PSP I have a Memory Stick Pro Duo 2GB will not open on pc &also not formated

it has a lock key on side try to pull it

Hello,
Try to update the firmware.
Hope it helps.

NO, DSC-T1 will not accept such big memory card as its hardware supports maximum 2GB card memory that is more then enough for it because its 6 mega pixel camera.

Format memory stick, if no data on it.
If there is data on memory stick, copy it on PC using any good card reader.

The memory card can't be more then 2gb...the camera won't support more than that. Have you formatted the memory with the camera? If not try that, don't format the card with your computer.

Try and format the card with the camera. Got to use the menu settings for that.
