Compact cameras are not ideal for this kind of subject. Depending on the amount of manual control available, set a high ISO, a medium aperture and a slow shutter speed with the camera on a tripod.
Thank you. If this device will accept a memory stick, then the make is immaterial. As for overwriting files, this will only happen if the files have the same name as the ones already on the device. To be sure, rename the ones you wish to copy across before you do so - a simple alpha-numeric character at the end of each file name will do the trick. HTH

Since you have omitted to inform us as to what the actual equipment is, we cannot answer this question, I'm afraid. May I suggest that you consult the manual.
Remove the batteries, clean all the connection tabs and battery terminals-tips etc with a simple pencil eraser. Poor connections cause this symptom. There's a layer of corrosion that's not even visable that is common on these.
