How to format or wipe a compact flash that is used for an embedded operating system?

Q. I have an ATP 4GB Compact Flash that is used for a computer and not for photos or with a camera.
It is Linux OS and after I format it in Win XP, the files are still there. Is there a program such as Boot and Nuke(which is for IDE drives) that will wipe the compact flash clean??
I've also tried to fdisk/format in DOS which does not work either. Any suggestions?

A. I'd say you have a bigger problem. Formatting isn't typically conditional. You don't complete a format, only to find that there are still files a card or drive. When a new file table is applied to a media device, it should be destroying any data on the card. I would use the Windows Disk Utility to delete the partition on that card, and then apply a new format to the drive. Do not use the Quick Format option either.

Do you think a Unix or Linux Administrator can get a job almost anywhere in the world easily?
Q. Let's say a person from America go to Asia, Europe, Africa, South America, or whatever. Do you think it would be easy to get a job since they have Linux Administration experience?

A. if you have the Linux qualifications then yes you will get a job any where in the world,
Linux runs the Internet,
Linux runs 455 of the worlds fastest top 500 HPC (High Powered Computers) Microsoft have 1 HPC in the bottom 45 (their own system)

You use Linux every day and don't know it, Linux run all domestic appliances from TV's Microwaves, Washers, Dryers, In car computers The list of embedded Linux in use is endless

Why is Linux the operating system of choice for so many electronic gadgets?
Q. i need to know why Linux is the operating system of choice for so many electronic gadgets?

A. DavoJo has a good answer, but I'm going to go a little further and mention that embedded developers have the freedom to easily compile in only the features they need, which results is a fast-booting, bloat-free, lean operating system that is still as feature-rich as they desire.

Adding drivers for specialized hardware is easier than with other systems (Greg Kroah-Hartman and his team of volunteers will even write the drivers for you if you just provide specs), so hardware compatibility is a non-issue. With the abundance of Unix and portable C software available, software compatibility is also good.

Finally, Linux is free and easy to license, as long as you don't blatantly violate the GPL. (As of now, Linux is still licensed under version 2 of the GPL, so you still have a good number of options as far as how you use it and what you use it with.)
