Re: Creating a "bootable" SD Card?

Fri Mar 16, 2012 12:22 pm

According to: http://russelldavis.org/2012/0.....n-windows/


The main gotcha is that although your computer has a builtin sd card reader/writer and it works with your cellphone or camera sd card perfectly well it might not work for creating a bootable sd. The biggest problem builtin sd card reader/writer is the ricoh one in HP laptops although other makes of sd card hardware and laptops also have this problem. When you use a builtin reader/writer and it is goingto fail it doesn't always tell you that it's failed so the first thing you now something is wrong is that your raspberry pi (or other target device) won't boot So although you have a builtin sd card reader/writer it is a good idea to get hold of a USB SD card reader/writer and use that for making your bootable SD card. [I have no real idea why builtin reader/writers have problems making bootable sd cards but my thinking is that the controller in the builtin ones was cut down for windows machines to save a few pennies as noone thought that they'd want to write to the 0 to xxxx areas of the SD card]


What are forum users opinions on this? I expect the vast majority of people with a computer made in the last few years will have an inbuilt reader in their system.

I agree with it.

New Dell Latitude Laptop, Windows 7 32-bit.

Built-in SD Card Reader failed to write the image, £3.50 USB card reader succeeded in writing the image.

I have no idea why that should be, since I know nothing about how SD cards and their filesystems are implemented, but it is empirically true.
