If your computer refuses to start up and you are viewing a Windows error message or, worse yet, a bright blue error screen then you will need to take your DIY data recovery a step further. The data recovery tool to use for these kinds of problems needs to be Windows based and either a FAT data recovery tool or a NTFS recovery program. These are the two different file placement systems used by Windows. You must match the program to your computer. If your computer is running any version of Windows from XP onward it is most likely formatted in NTFS. Better quality data recovery programs are sold in these two versions. With these programs you will be able to examine the contents of your drive and choose the programs you wish to recover.
