In short, format is to initialize and prepare a storage medium such as a hard drive or flash drive to be recognized, read or written by computer. Formatting has low- level and high-level. Most users only perform high-level formatting such as accidentally formatting a disk. For example, when you are ready to format your partition, you may choose quick format or regular format. The difference between them is whether the volume will scan the bad sector. When running a regular format command, each sector on the partition will be labeled as a re-useable space in the file location of the current partition, and the system scans the hard disk to check if there is any bad sector. The scanning for bad sectors takes most of the time of formatting the disk partition. While if you choose the ‘quick format’, it will only mark delete tags form file allocation table of the partition, without scanning the disk to check for bad sectors. Only when the hard disk has been previously formatted and ensure no bad sector, we can use 'quick format'. All the data will be removed from the volume if you perform quick format.
When we need to format storage medium?
When you need to reformat or format your PC, USB and other storage devices, it often comes from the following errors:
Media/Drive is not formatted would you like to format now?"
- Operating System not found
- Invalid or corrupted or damaged FAT and NTFS partitions table
- Cannot find file or program
- Invalid command
- Primary/Secondary HDD failure
- Non system disk
What happened after formatting?
Theoretically, quick format does not delete the data actually. It just marks the head of section where data locals by a kind of symbols telling operating system that this section is re-useable. During a format, you are just allowing the system to re-use the space on your drive by over-writing existing files. In this case, it is still possible to recover all data from formatted hard disk so long as there is no new data stored on after formatting. What you should do is to perform format recovery.
