Until we have reached the part for full removal / full erase of the entire disk space, these methods only apply to conventional HDDs.Įrase free disk space (for conventional HDDs only) Now let’s have a closer look at some methods of safe – and not too safe – file removal in Windows. Yet if you remove some banking data, work documents or data required for online authentication, it’s preferable to remove such files in a way that makes their recovery without your knowledge impossible. If the data you don’t want to be restored is not of vital importance and can’t be used against you, then delete it in the standard way and don’t worry. That is, if you are satisfied with the current level of safety, it is going to be safe.

So how could you remove this information reliably so that it doesn’t fall into the wrong hands? Is that safe?īefore learning how to safely erase data from an SSD, let’s find out what exactly it means to you. It’s quite possible you deal with secret or sensitive data, documents containing trade secrets, or just store your personal banking data openly. So my advice is to make sure you have encrypted your SSD and find out if your disk supports the TRIM feature.Īctually, this problem is not too relevant for most users, but at the same time, you might be worried that hackers may get their hand on the data deleted from your disk. In an attempt to erase one file reliably, the disk actually retained from 4% to 75% of the file’s internal data.

A group of engineers at the University of California, San Diego studied this topic and witnessed first-hand that completely erasing data from an SSD is very difficult. So how can you overwrite the unnecessary files for sure? In fact, it’s next to impossible to erase a specific file completely on an SSD. Therefore, if you delete a file with the address 2871 (for example), the deleted data may be relocated to another area on the disk sooner or later, until the SSD’s electronic brain decides to overwrite it.

This way, all memory blocks will be worn out evenly, and the risk of separate blocks to get out of order is reduced. This standard feature allows to extend the SSD lifespan considerably by suggesting rational use of the read/write cycles – the guaranteed number of which is limited. As solid-state drives are different from conventional HDDS in terms of technology, SSDs always write and move written data according to a special scheme so all physical memory of the storage device is used uniformly and proportionally.

Now the problem of deleting files in an ordinary way becomes more obvious. In the right column, you can see additional information, including what specific data is written at this address. The red letter X marks the MFT addresses which have been overwritten completely or partially, and the lines without such letter represent the addresses that have not been overwritten yet. The left column displays the list of files the app could find on the disk. Let’s illustrate it with the example: we’ll use an app called NTFSWalker to scan any NTFS partition on a hard disk.

Data in the system disk (by default, it’s С:\) can be overwritten very soon, even within several minutes, As Windows writes new temporary data to disk all the time: system cache, program cache, web cache and so on. The time required for this to happen can be quite long – up to a few months, but basically, it depends on the total size of your hard disk, on how you use your computer, and on what kind of local disk the old data is stored in. Therefore, the deleted file will be stored in the hard disk until the operating system overwrites this area with new data. The column on the right presents the way this data looks as simple text.

The middle column shows data in the hexadecimal code (also known as HEX). The first column on the left displays blocks of addresses.
