Formatting a hard drive is done for the first time to make it usable and separate it into several partitions for storing system files and user files, where in it creates internal address table to store the address of the data that is stored on the drive. Formatting or reformatting a hard drive may be essential in the following situations –
- Adding more than one operating systems to the hard disk, you may need to format the drive
- While upgrading the operating system to a latest version
- To remove virus affected files / folders
- When the file system is damaged or corrupt
- To speed up the PC / laptop
- When hard drive is having bad sectors or system errors
- You may sometimes accidentally format d: drive instead of f: drive
Formatting, reformatting or repartitioning of the hard disk drive will erase the address table present on the drive and makes the data inaccessible, though it is still present on the drive. It is recommended that you have a backup of your data before formatting the drive, except in the case of viruses where in you will not be able to take proper backup. However, in some cases like file system corruption or system crash can make a hard drive inaccessible. Thus, you will be left with no choice but to format or reformat the drive to make it functional again at the cost of your data. Although, the data gets inaccessible, you can still recover data from hard drive using formatted partition recovery software.
Using this software, you can recover data from accidentally formatted hard drive effectively. Recovery of photos, office files, email archives, audio and video files is possible if the formatted drive, memory card, USB drive, iPod etc. is not used to ensure that the data or files present on it did not get overwritten.
