You can look at it but you won't see anything. If you want to see what you're shooting, you have to use the viewfinder.

The K100D works with SD cards. Your 4GB card is actually an SDHC card. While it fits into the slot is is electronically incompatible.

Consider NOT connecting your camera to your computer.The best way to download pictures from your camera to your computer involves removing the memory card from the camera and plugging it into a card reader (either built-in to the computer or connected via USB or FireWire). This is likely to be faster than connecting the camera to the computer, and won't run down your camera's batteries.Once the card is plugged in, it will appear to your computer as a removable drive. You can use the operating system's drag&drop facility to copy pictures from the card to the computer's hard drive, the same way you copy any other files. Or you can use any photo cataloging program such as Picasa.

That is the proper function upon start up, you can disable this in the menu settings.

Don't know what exactly the issue is, but digital cameras these days all have a setting to adjust the aperture. If a picture is dark, you can change the setting to have the aperture open for longer (this lets more light in). It wouldn't be an automatic setting, unfortunately, but this is something you have to do anyways when its dark outside and you are taking pictures at night. Just make sure you steady the camera (if the aperture is open for very long, then you may need a tripod) when taking the picture or else it will be blurry.

First make sure you are using fresh lithium batteries. These cameras indicate low batteries quite early on. Rechargeables even when freshly charged are marginal.

If the problem persists remove the batteries. Set the camera switch to the off position. Set the focus switch to manual. Wait at least a minute. Then replace the batteries and switch on again.

Operating with low batteries can confuse the firmware and it may be stuck in a low-battery loop. If this is the case this should reset the camera by allowing the electronics to power-down completely.

If this does not work you wiil have to contact pentax support.

It seems you need to open the camera and check the SD card slot.
this tip may help you How to fix a ‘card locked’ problem

Make sure your new memory card is an SD card. If it's larger than 2GB then it's actually an SDHC card. While it fits into the slot, an SDHC card will not work in devices designed only for SD cards.

I have the same problem please let me know if any working fix occurs

It's the shutter...the 2nd half is closing before the 1st half is done. Go into the menu and scroll to "reset" and follow the on-screen instructions...might work.

There is a sliding switch on the SD card marked 'lock'. Slide it up to unlock the card.

There is a little sliding switch marked 'lock' on SD card. Move it up to unlock it.

I believe if its an hd camera it needs an eight or the card is bad and wont formatte

That's the biggest "no-no" in the digital camera world. You need to e-mail the techs at the support section of the Pentax website for specific directions about what to do next. There's also a link for a "live chat" if you prefer that method.

This is usually a memroy issue. When a digital camera snaps a photo, it saves it to a buffer until it can write it to the memory card.

Try a different memory card. If this does not fix your issue then unfortunately the issue is with the buffer memory. This might be fixed with a firmware wipe but it might also need expert repair.

Obviously, the camera is defective. You need to return it.
