SD Card Formatter

SD cards can be formatted using the standard OS utilities. As per the SD Association formatting SD cards using the standard OS utilities can lead to less than optimal performance. 

Thus it is recommended to use the SD card formatter created by the SD Association. 

NOTE:

All SD cards have a "Protected Area" on the card for the SD standards security function. The formatter will not format this protected area. It is advised to use appropriate application software that provides SD security function to format the protected area.

The selected file is not an valid iso file error by Windows 7 USB/DVD download tool

Did any of you wanted to create a USB image to setup Windows 7/8? Well there is a tool created by Microsoft for that. It's called "Windows 7 USB DVD Download Tool". You can download the tool from this.

The tool works fine but in an unexpected situations you might encounter the following error.

The reason for the above is that the ISO you created is not according to the Microsoft Standard's for the installation media.

Generally when an ISO image is created the ISO 9660, CD File System is set. But in addition to this the above tool requires 2 more attributes set in the ISO.

1. Joliet

2. UDF

Once the above is set the newly created file is considered a valid ISO file by the tool.

You could use UltraISO to create an Windows ISO file. It has the options to specify the above mentioned attributes.
