Hard disk erased? Don't worry, you can still save your data. Use the links below to quickly navigate to the section of the article that interests you the most.
People make mistakes. One of those mistakes could be completely wiping your hard drive without first copying all the necessary files you needed. When this happens, it’s easy to immediately start panicking over the thought that your data is gone forever.
Luckily, it’s not the end of the world. There are various ways that you can get your data back, and oftentimes it’s much easier than you might think. Let’s look at a few ways you can recover files from a wiped hard drive.
While recovery is definitely possible, you want to act as fast as possible to ensure your data isn’t overwritten. Before you try to recover the data, make sure you read this entire article first.
Can You Recover an Accidentally Erased Hard Drive?
In most instances, recovery from an erased hard drive is possible. When you erase data from a hard drive, the data becomes inaccessible, but it still physically remains on the drive itself. This data will remain on the disk until new data needs to use this space. When new data needs to be written to this particular space on the hard drive, it will overwrite it. It’s in this window of opportunity that data recovery has the highest chance of success.
But, sometimes, there are factors that come into play that make the ordeal either difficult or impossible. Here are a few reasons why data recovery might not be possible from an internal or external hard drive:
- 💻 SSD with TRIM enabled – Solid State Drives (SSD) work differently from mechanical hard disk drives (HDD). Instead of data remaining on the drive until the space needs to be used, an SSD with TRIM enabled will completely erase the data shortly after it’s deleted by the user. Because there is no longer any trace of the data you want to recover, this makes recovery next to impossible if you’ve erased it from an SSD with TRIM enabled unless you attempt recovery immediately.
- ❌ Full format – Typically, when you format a drive, most people opt for a quick format. It’s convenient, fast, and works well enough. The benefit (and in some cases, drawback) of a quick format is that the deleted data can still be recovered. If you perform a full format on a drive, the data itself is erased and replaced with zeroes twice over. The act of replacing all the data on the drive with zeros means that there is no trace of the data left, which, in turn, means that recovery is no longer possible.
- 💥 Extensive physical damage – If the drive has sustained severe physical damage, it could mean that the drive no longer functions, or the parts in which the data is stored has been compromised. Typical hard drives store data on platters. Anything, even the smallest piece of dust, can damage the exposed platter and render the drive unusable. This is why hard drives are sealed very tightly, and any commercial-grade data recovery services have special rooms that keep dust and other foreign particles out of the air.
How to Recover Data From an Accidentally Wiped Hard Drive
If your drive can be recognized by a computer, you can still try your hand at recovering the data that was lost. Data recovery from an erased hard drive is through the use of data recovery software, and we’re going to take a look at one for each operating system.

How to Protect Your Hard Drive Data
If you’re not prepared for a situation where your data disappears, recovery can be a stressful process, especially if it’s your first time doing it. To avoid the stress of recovering your data going forward, consider implementing some proactive measures that keep your data safe.
🗄️ Make regular backups
Backups are a super-easy way of making sure your data is safe, even in the event of catastrophic loss. If you have a handful of important files, consider uploading them to Google Drive or Dropbox so that you not only have the peace of mind of having a backup off-site, you can access it anywhere with an internet connection. If you have a lot of files that may take too long to upload, consider making backups to an external drive that’s stored safely. A reliable backup and recovery software tool might come in handy.
⏏️ Eject drives safely
Before removing any storage media from your computer, make sure to eject it safely before doing so. If the drive is removed during an operation, it can cause not only file corruption but corruption to the entire partition. So, take the extra few seconds needed to eject each drive safely before removal.
🔐 Encrypt drives
Encrypt your hard drive data to protect it from unauthorized access. There are various encryption software options available, such as VeraCrypt, BitLocker, and FileVault.
👾 Use firewall and anti-virus software
Use firewall and anti-virus software tools to protect your computer and hard drive from data loss caused by malware and viruses.
📊 Arm yourself with HDD monitoring tools
Use disk checking and repair tools to regularly check your drive health and fix hard drive errors. Protect yourself from data loss caused by faulty or bad sectors.
⏱️ Take your time
Sometimes, even the most critical errors can be avoided by taking extra care when making important changes to a drive. For instance, before formatting a drive, double-check that you’ve backed up the necessary data from the drive and that the correct drive is selected to be formatted.
Yes. While uncommon, if something has damaged the hard drive or if the hard drive is simply starting to fail, it’s possible for it to erase itself.
Yes. Through the use of data recovery tools, the data that resided on your hard drive can be recovered. However, data recovery isn’t always possible, so it will depend on how effectively the data was erased and the physical condition of the drive itself.
It depends. In most cases, data recovery is possible if the data still physically resides on the disk. That is, if the physical location on the drive where the data is stored hasn’t been overwritten with new data. Data recovery becomes impossible if the data was erased from an SSD with TRIM enabled, the drive was fully formatted instead of quick formatted, or the drive has sustained extensive physical damage.
A DoD wipe involves the data being overwritten several times in an attempt to render it unrecoverable. At this point, standard recovery methods are of no use. Government agencies may have the ability to recover fragments of the data, but even this is not guaranteed. Because of how effective a DoD wipe is, there is next to no chance of recovery.
Yes, there are various solutions available for recovering data from a wiped hard drive. In most cases, the easiest and fastest way to recover data from a wiped hard drive is through recovery software as it does most of the work for you.
Disk Utility is a very powerful tool available on Mac, and can be used to repair a failed hard drive.
