To permanently delete everything, you need to perform a factory reset on your device (phone, computer) and use specialized software (like Link: Eraser https://techcommunity.microsoft.com/discussions/windowsinsiderprogram/how-do-i-delete-files-permanently-from-my-computer-and-make-it-unrecoverable/4253372} or !/nav>>Link: DBAN https://www.reddit.com/r/techsupport/comments/1gts2nj/how_do_i_delete_everything_off_of_my_computer/}, !/nav>>Link: !/nav>> for drives) to overwrite data, effectively making it unrecoverable, especially for physical devices like hard drives you plan to discard. Remember to back up important data first, then use built-in reset options for devices, and for PCs, consider a full drive wipe before reinstalling the OS to ensure nothing is left behind.
A deleted file doesn't really disappear from your hard drive; it stays there until new data fills up the space it occupied. This process might be hard to understand for people who don't know much about how computers handle files.
Here's how:
In reality, deleting a file doesn't immediately remove it from your hard drive. Instead, the system just marks that space as available for new data. Until something else takes its place, that file can still be recovered. For anyone unfamiliar with how digital storage works, this concept can be a bit tricky.
To permanently delete files from a Windows computer and make them unrecoverable:
If you permanently deleted files or emptied the recycle bin, you might still recover them using data recovery tools. Avoid using the drive where the files were located to prevent overwriting. Install a reliable recovery tool, scan the drive, and preview recoverable files.
How can I completely wipe my computer harddrive?
Think deleting your old social media accounts, emails, or online subscriptions means your data is gone forever? Think again. Even when you delete an account, companies rarely erase your data completely. Instead, it lingers on their servers—accessible to advertisers, data brokers, and even hackers.
The answer is yes — even if you have deleted the photos from your drive, you can still recover old deleted photos from your drive, sometimes. The method on how to restore deleted photos in this article will work for all storage media devices, from SD cards and USB flash drives, to modern SSDs and HDDs.
While forensic analysts can still access data on some traditional hard drives or unencrypted devices, these cases are becoming the exception rather than the norm. In most modern devices, once data has been deleted—especially from an encrypted drive or SSD—the chances of successful recovery are minimal.
Special overwriting software is available if you want to delete something completely and irretrievably. It works by overwriting the data once or multiple times with predefined characters or random numbers. This is sufficient in most cases; the data is truly gone and can't be recovered.
Using Software to Wipe Drives
Software tools are highly effective for ensuring permanent deletion. Programs like Eraser and CCleaner offer secure wiping features. These tools overwrite the disk with random data, making the original information irretrievable.
Destroying media can also prevent data recovery.
On your computer or phone, deleting a file doesn't erase it immediately. Instead, the system removes the reference to it, meaning the file is now invisible to you but still fully recoverable with the right tools. That's why data recovery software exists.
Check the Recycle Bin
On almost all computer systems, once a file has been deleted this is the place it will end up next. With a quick search in the Bin, your wayward file can easily be selected and restored to its original folder as long as you have not emptied it.
When you delete your files, they are being sent to the Recycle Bin, where they can be recovered at any time. Recycle Bin in itself is a protection mechanism by the Windows OS to provide assurance to the user that if some files do get deleted that they still can be reverted back into the working state.
Delete photos & videos permanently
You can restore recently deleted photos and videos that are still in your trash. Items that are permanently deleted can't be restored. Backed up photos and videos stay in your trash for 60 days. Photos and videos that weren't backed up stay in your trash for 30 days.
In reality, deleted photos might not disappear right away. In fact, depending on how and when the deletion occurred, there's a good chance the data is still on your phone, just out of view. That means recovery is sometimes possible—if you know where to look and act fast enough.
HUANG: So we think of the internet as forever, like a place where old posts and photos can come back and haunt us. Is that no longer true? SMITH: It is definitely no longer true. There's a concept known as digital decay, which refers to online media just kind of disappearing for a variety of reasons.
Cops using forensic software can often look into a device's primary storage (as well as cloud storage) and pull up information that the user may have believed was permanently deleted long ago. That capability extends beyond images and documents. It can include items stored in databases like text messages and emails.
In most email programs and web interfaces, deleting a message doesn't actually delete it. Instead, the message is moved to a special folder, typically called “trash” or “deleted items”. What happens next depends on the program or service.
For this reason, we have decided to debunk four of the most popular hard drive destruction myths: Myth #1: You can destroy a hard drive by putting it in water. Truth: Hard drives are pretty well sealed, so dunking it into water quickly will most likely not affect it at all.
The difference between deleting a file and wiping a file on a hard drive is simple. When deleting a file the data remains on the drive while wiping a file overwrite the data with (random) other data destroying the original data.
You can use data recovery software to scan the wiped hard drive and check if any recoverable data remains. If the scan comes up empty, it means your data has been successfully wiped. Double-checking ensures that no traces of personal information are left behind.
