This article describes how to convert a hard disk that uses the File Allocation Table (FAT or FAT16) file system to the FAT32 file system using Drive Converter.
WARNING: After you convert your hard disk to FAT32, you are unable to convert it back to the original FAT system. Also, this procedure does not work if your hard disk has bad sectors.
To convert a drive to the FAT32 file system, use the following steps.
NOTE: Before you convert to the FAT32 file system, uninstall any utilities or tools that protect or encrypt the Master Boot Record (MBR) or partition table (for example, uninstall Bootlock included with Symantec Norton Your Eyes Only).
Method 2At a command prompt, type cvt drive: /cvt32 and then press ENTER, where drive is the drive you want to convert to the FAT32 file system.
For more information about the FAT32 file system, see the following article in the Microsoft Knowledge Base:
