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.
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.

- Launch PhotoRec with the command sudo photorec.
- Select the hard drive that was erased, then press Enter to proceed.
- Select your partition type. Select [File Opt], then press Enter.
- Select the file types you want to recover. When finished, press Enter to go back.
- Select the partition that had the contents erased, then select [Search] and press Enter.
- Select your filesystem type. Linux partitions will be ext2/ext3, and others (such as FAT or NTFS) will be Other. Press Enter.
- To scan the whole partition, select Whole and press Enter.
- Choose the directory for the recovered files to be sent to.
How to Protect Your 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.
- 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.
- 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.
All drives are susceptible to data loss through different means. If your drive has been erased, you should first look at what happened to try and correct it going forward. If it was simply a mistake, then make use of one of the many recovery solutions to get your data back.
Recovery is always dependent on the situation. While there are many ways to recover data, the success rate depends on how effectively the data was erased. While there are some cases where data recovery is impossible, most of the time the data can be recovered to some extent.
