What is corrupted FAT?
The name of the FAT file system comes from the name of the key structure of the file system - the File Allocation Table.
The FAT file system has many versions - FAT12, FAT16, FAT32 and all of these versions differ in how many bits are used to store the cluster number.
The FAT file system stores file location information in two areas.
If some of the metadata records are corrupted, then the user cannot access the volume and, accordingly, the data stored on it.
Often, for the user, it looks like this - the user connects a pen drive or a memory card to the PC and gest a message
that it must be formatted before using the device. However, formatting the device results in data loss.
This situation is also
called RAW filesystem.
To recover data, you need to use a software to recover data from the FAT file system.
There is also another way to fix the FAT file system; however, we do not recommend doing this unless you have special
knowledge in data storage. You can learn more about this method
on this page.
