My kingmax 1GB memory card has become unformatted.so how do i reformat it?

You can try recovery tool to see whether your memory card corrupted or not. For example, 4Card Recovery, which is able to recover various files in a few minutes.
Step one, download 4Card Recovery online and install it on your computer.
Step two, run it and choose the files that you want to recover, of course, you can choose recover all files in case of the omission of anything.
Step three, scan it by clicking the 'next' button and wait for about ten minutes.
Step four, save the recovered files on other part to avoid losing it again.
Hope you can solve the problem with this. Have a try.

Hi,
Please check the speed in MHZ of old RAM and New 1GB RAM.
Some times if speed wont match this problem occur.
Remove old RAMs and add only 1GB RAM and start the system.

I hope it will help you.

Thanks for using FixYa.

No. The maximum size of memory card supported by this model is 1GB microSD type only. So it wont recognize your 2 GB memory card.

If you have the HP M407, the maximum capacity sd card it can use is a 1gb. I had the same problem and a 1gb card solved the problem. Hope this helps.

Normally you should have an option on the mobile for reformatting if not you will have to use the adaptor & format it on the PC

You need to google for an app from HP called SP27608.exe.
This will read the card as 4gb and let you reformat it.
