To do a full format as described above, you’ll need Windows Vista or later. Instead, it overwrites the file table and checks the disk for bad sectors. Note: In Windows XP, a full format does not overwrite the disk with zeros. There is some meta data on the disk, but this was recently written during the format (as you can see by the “created” date). None of the old files that were on the disk before the format show up. Let’s try analyzing it again in R-Studio: For this reason, it’ll take much longer than a Quick Format.

But if you are selling, donating or trashing your hard drive, a Quick Format isn’t a good idea.Ībove, we saw that a quick formatted drive ended up blank in Windows Explorer. So, for most purposes, the disk is now “blank.” This is good if you are going to be reusing the disk yourself or if you are reinstalling an operating system. The new file table doesn’t have any information about the data that was on the disk before the format.
Instead, a Quick Format writes a new file table onto the drive. What makes a Quick Format quick is that it doesn’t delete all data on the disk. The drive will appear to be blank in Windows Explorer. In the Format disk window, check Quick Format and click Start. You can do it from Windows Explorer by clicking Start > Computer and then right-clicking the drive and choosing Format… DBAN: Erase a Hard Drive without Removing ItĪ Quick Format is a fast way to prep an old drive for a new life.Eraser: Secure Erase and Erase Unused Space.How to Perform a Full Format / Is a Full Format Secure?.How to Perform a Quick Format / Is a Quick Format Secure?.To illustrate this, let’s take a look at a Windows Quick Format vs. If you don’t sanitize a hard drive with a secure format, then chances are there are gigabytes worth of data that can be easily undeleted by any kid with a free data recovery utility off the Internet.
