There are times when we have to format a hard drive to troubleshoot an issue or simply end up doing it by mistake. Since it can lead to an instant loss of our data, it can be a tedious situation for many. The good news is it’s possible to unformat a hard drive on Mac or Windows depending on the formatting type and formatting time. Let’s get down to business.

Can I Unformat My Disk After Accidental Formatting?

Yes, it is possible to unformat your hard drive after you’ve hit the formatting button by accident. Whether or not this applies to your specific case depends on several factors. So let us ask you a couple of questions before we can set your mind at ease:

  • How did you format your hard drive?
  • When did you format your hard drive?
  • Did you overwrite it in the meantime?

We’ll give you some time to think about it. Resetting a hard drive to a pre-formatting state cannot always be done, so getting these details right is very important. While you’re trying to figure out how it all went down, we’ll try to refresh your memory with a few formatting basics.

Basically, there are two types of formatting – Quick Format and Full Format. If you have performed a full format on your hard drive, any unformatting attempt would be a waste of time, as you can’t unformat a fully formatted hard drive.

If you have, however, performed a quick format, read on.

If this happened a while ago and you’ve installed a new OS or overwritten hard drive with new files, you won’t be able to recover much of what’s left on the formatted drive.

To answer your question, you can unformat your disk only if you’ve performed a quick format and acted quickly. Quick formatting doesn’t really erase anything from the hard drive. It merely pushes it to the basement to make space for more. You have a high opportunity to recover the deleted files as long as they are not overwritten by new data.

  1. Go to Settings > Update & Security. Choose the Backup option.

I would recommend using Wondershare Recoverit - Data Recovery for Windows that can help you get back your lost files under all scenarios.

Why You Should Always Remember to Back Up Your Drive

the importance of hard drive backup

Now you know how to unformat an internal and external hard drive on Windows and Mac. Data loss is always scary, but you can finally relax. You’ve learned an important lesson the hard way. Do you know what it is? No, we don’t mean the practical steps and skills for data recovery.

There are many different ways you can lose data, a few ways to recover it, and only one way to prevent all this from happening again – you need to start backing up your hard drive.

We’ve prepared a few useful tips in case this is a whole new territory for you:

  • You should always have multiple backup options – preferably, one onsite and one offsite. We recommend a combination of external storage and online backup/cloud storage.
  • While you can also backup an entire operating system, it’s more important to save your personal files and files that, unlike programs and settings, cannot be replaced.
  • Automated backups are an excellent way to ensure that nothing slips through the cracks. Some backup solutions can automatically back up new data every single day!
  • That said, the more often you back up your data, the less you need to worry about it. While you might not need daily backups, saving new data once a week is a must.

If you’re looking for a smart backup solution, you might want to try Wondershare UBackit. It’s designed as an all-in-one data backup manager that lets you schedule automatic file backups from your hard drive, as well as perform partition, disk, NAS, Outlook backup, and more.


To sum it up – unless you have performed a full format or downloaded a lot of new files to your formatted hard drive, you have a pretty good chance of unformatting a hard drive on both Windows and Mac. There are two ways to do that safely – from a local backup or using a data recovery tool like Recoverit.
