What Is Formatting?

Wikipedia gives a very elaborate description on disk formatting.

In short, disk formatting is the process of preparing a data storage device such as a hard disk drive, solid-state drive, floppy disk or USB flash drive for initial use. The formatting operation will go through three parts: low-level formatting -> partitioning -> high-level formatting. Each part processes different things.

But here for average computer users like us, who want to clear a computer virus by formatting, the 'formatting' usually refers to the 'high-level formatting'. It's for setting up an empty file system on a disk partition or logical volume and, for PCs, installting boot sector. This is a fast opeartion, and the entire lgoical drive or partition may optionally be scanned for detects. While in case of floppy disks and flash drives, both high-level and low-level formatting are customarily performed in one pass by the disk formatting software.

Can Viruses Really Survive Formatting?

Since formatting a hard disk or flash drive will initialize the device and set it up as a new polished one, yes, to some degree, formatting a hard drive deletes all data written on the hard drive, including the virus that may have infected it.

Despite that formatting is able to remove data together with the virus, is it a permanent choice? What's the most reasonable way to get rid of a computer virus? The following two facts are important.

1. Big concern with data

For internal hard disks/SSD in a laptop or computer as well as external devices, such as USB flash drive, SD card and removable hard drive, the suggested way to remove a virus once for good is first of all, to run an anti virus program to clear virus. The anti -virus program will possibly give you chance to save some important files. Then, to completely kill the virus that may hide somewhere under some folders, formatting is 100% required as the final step.

Even the anti-virus program did nothing helpful to data, you can hopefully recover some infected files with aforementioned EaseUS Data Recovery Wizard.

2. No worries about data

Things would be much easier to handle. You can directly choose to format the drive using a proper method to clean the virus off from a disk by skipping the help of anti-virus software. While performing the disk formatting, some of you may hear the other suggestion of wiping a hard drive partition to remove the virus. Does "wiping" work better than "formatting"? In fact, wiping the partition contents will make no difference regarding the virus removal part. However, data erased by formatting is usually recoverable by using some special data recovery software, and by wiping you can no longer restore the data.
