What else can I help you with?
If you have 512mb memory card why do you only have 133mb available?
There is probably something already on the card. Put it in a card reader and find out what it is. If you don't want it, put the card in the camera and format it. If that doesn't help, it is possible that the chip is damaged. I would replace it before taking any important photos.
Can a computer run on an external hard drive only?
Yes, you should be able to install an operating to an external hard drive. You might have to set it to boot in the BIOS so you can install the OS. A computer needs an operating system to run, so as long as it is installed on a hard drive, it should not matter whether its internal or external. Remember, it depends on what port you are using depends on the speed, so if you have only usb, this will be a lot slower then your internal hard drive port. P ata, ide drive transfer speed- 133mb USB- 60mb Every port has a speed rating. So you don't want a slower port then your internal port.
What is the difference between eide and sata interface on a PC hard drive?
EIDE's enhancements to Integrated Drive Electronics (IDE) make it possible to address a hard disk larger than 528 Mbytes.Serial Advanced Technology Attachment (SATA)SATA are usually running in IDE emulation mode ------------------------------------------------------------------------------------ EIDE is an older legacy connection that supports data transfer speeds of about 133mb/sec. It uses thicker 40-pin ribbon cables. SATA is a newer device technology that connects harddrives with a much smaller cable and supports a lot faster data transfer in the range of 150-300mb/sec. Depending on whether you have SATA-150 or 300. (fightermage)
