Disadvantages of File Allocation Table(FAT)
- Support file sizes upto 4 Gigabyte
- Has negligible amount of security to the data stored. Therefore, data could be tampered illicitly
- Has no fault tolerance
- No support for Encryption of individual file or folder
- No support for data recovery in case of data loss, as opposed to newer file systems which implement certain measures for ease in data recovery in case of data loss (ex. NTFS has Journaling which could be used for speeding up the process of data recovery)
- No longer being supported by several technological manufacturers, due to newer/better filesystems taking precedence
