Is one pass enough for disk wiping?
NIST clearly states that one write pass is sufficient to erase data from drives beyond recovery. In recent years with innovations around the hard drive technology, such as the high data density on disk platters, makes data recovery impossible after single overwriting pass followed by verification of the overwrite.
Windows 10
Click Update and Security, then “Recovery” in the sidebar. Under “Reset this PC,” click “Get started,” then “Remove everything.” When you get to the “Additional settings” screen, click “Change settings” and make sure the “Clean data” and “Delete files from all drives” options are enabled.
To reset your PC, go to Start > Settings > Update & Security > Recovery > Reset this PC > Get Started. Then, select Keep my files, choose cloud or local, change your settings, and set Restore preinstalled apps? to No.
Free up space with Disk Cleanup
If your system doesn't have Storage Sense, you can use the Disk Cleanup tool to delete temporary files and system files from your device. In the search box on the taskbar, type disk cleanup, then select it from the results. Select the drive you want to clean up files for, then select OK.
The United States Department of Defense recommends using a 7-pass wipe to clean media. For all wipe options, OPSWAT conducts a low-level (meaning sector by sector) wipe of the media, which is the slower and more rigorous method of data erasure.
It overwrites all sectors with zeroes on the first pass, overwrites them with ones on the second pass and then uses a random pattern on the third pass. A standard DoD 5220.22-M erasure is 7 passes. The more passes, the longer the secure erase takes.
For Windows 10, go to the Start Menu and click on Settings. Then navigate to Update & Security, and find the Recovery menu. Next, select Reset this PC and choose Get Started. Follow the instructions to revert your computer to when it was first unboxed.
Yes, you can fix a corrupted hard drive by formatting it with a new file system. Logical hard drive corruption is often caused by a damaged or corrupted file system. Formatting the partition will correct this.
Go to Settings > Change PC Settings > Update and recovery > Recovery. Click Get Started under the Remove everything and reinstall Windows section. Click Next, then choose Fully clean the drive to ensure everything is deleted. Click the Reset button and your drive is wiped, your PC is reset, and Windows is reinstalled.
You can choose to preserve just your personal files or to erase everything, depending on what you need. Go to Start > Settings > Update & security > Recovery, click Get started and select the appropriate option. Then follow the on-screen instructions to restore Windows 10 to a factory fresh state.
How long does a full computer wipe take?
As a factory reset takes away all your data, it is essential to Backup before the process. It usually takes around 30 minutes to 3 hours to reset, depending on your device configuration.
How long does it take to reset Windows 10? If you select “Just Remove My Files”, it may take around 2 hours. However, if you choose “Full Clean the Drive” here, it takes about 4 hours.
Why does my computer say there is not enough disk space when there is? There could be some hidden or virtual memory files taking up space, and you need to delete the files on the virtual partition. It is also possible that you have a disk format limitation.
Why is my hard drive still full after deleting files? Available disk space does not increase after deleting files. When a file is deleted, the space used on the disk is not reclaimed until the file is truly erased. The trash (recycle bin on Windows) is actually a hidden folder located in each hard drive.
The possible causes can be: Too many applications or files saved on the disk. There is not enough disk space. File system corruption on the hard drive.
The fact is that the drive has to be completely overwritten before your old data is securely destroyed, a process known as a disk wipe or a hard wipe. The most cited security standard is that the data should be overwritten three times in order to truly erase a disk.
The DoD wiping process runs a three-pass overwrite process for comprehensive yet efficient wiping as compared to other methods such as the 35-pass Gutmann standard.
Named after its developer, the Gutmann algorithm is a method of disk wiping that overwrites data using a total of 35 passes. This makes it one of the most secure data erasure methods, but also the most time-consuming.
An SSD that stores a single data bit per cell, known as single-level cell (SLC) NAND flash, can typically support up to 100,000 write cycles.
You Can Securely Wipe Your SSD
Wiping an SSD clean requires different tools than a regular hard drive. Now you know the options, you can securely erase your SSD before selling or donating it. Manufacturer secure erase options are handy, but the Parted Magic secure erase option is best.
How long until an SSD dies?
The most recent estimates put the age limit for SSDs around 10 years – though the average SSD lifespan is shorter. A joint study between Google and the University of Toronto tested SSDs over a multi-year period. It was found that the age of the SSD was the primary determinant of when an SSD stopped working.
Wiping a computer hard drive is different from shredding because it merely erases any stored information while keeping the physical hard drive intact. This is also different from moving documents to the trash or recycle bin because, even though the files are hidden from view, they remain on the device.
Since you don't want the new owner to be able to access the stored data on your drives, it is best to reset the device to erase everything on it.
After you drop off your old tech, our trusted recycling partners will wipe any remaining data from devices before determining if the product can be repaired, repurposed or recycled, but you can also wipe your hard drive before coming in. Here's how to do it.
- #1. Unplug and Re-plug the Corrupted/Unreadable Device.
- #2. Check and Repair Disk Error via CHKDSK.
- #3. Reinstall Disk Drivers.
- #4. Format Drive.
- #5. Recover Data.
To repair errors without scanning the disk for bad sectors, at the command prompt, type chkdsk volume: /f, and then press <Enter>. To repair errors, bad sectors, and readable information, at the command prompt, type chkdsk volume: /r, and then press <Enter>.
It is not a data recovery tool and will not recover lost or damaged files. CHKDSK will simply ensure the information currently on the disk is in a consistent and safe state. If files are damaged, the CHKDSK utility attempts to separate the damaged files and save the remnants as Filenn. chk.
The most effective way to destroy a hard drive is to shred it. Similar to shredding documents and paper, shredding turns a hard drive into a million tiny pieces that can't be put back together again, therefore destroying and erasing the data forever.
In Windows 10, click the Start menu and select the gear icon in the lower left to open up the Settings window. You can also select the Settings app from the app list. Under Settings, click Update & Security > Recovery, then select Get started under Reset this PC.
This reset option will reinstall Windows operating system and keeps your personal files, such as photos, music, videos or personal files. However, it will remove apps and drivers you installed, and also removes the changes you made to the settings.
Does wiping your PC make it faster?
In short, yes, a factory reset can temporarily speed up your computer, but there is no guarantee that it will stay that way for long. In some cases, a computer may return to its slow state as it gets used over time.
The reason is that during the delete process, Windows 10 runs calculations, analyzes, and shows updates as files and folders get deleted on the screen, something that usually takes time when deleting a large folder with thousands of files and subfolders.
It takes too long because of a lot of data, background updates, low-end PC, or any hardware issue. An average time for a Windows reset is about 3 hours. If you are resetting your windows after making a backup, it will take more time to restore that backup after the reset.
They both do basically the same, except selecting Clean The Drive will write zeros to the entire drive before reinstalling... Just Remove Files deletes the Files without writing zeros...

It can take anywhere from 1-2 passes to 40 passes and more to complete. There is no set amount of defragging. You can also manually set the passes required if you use third-party tools. Defragmenting your hard drive at regular intervals helps you maintain your hard drive for a longer time.
This process could take several minutes to several hours depending on how big the drive is and what method you choose. See the tip at the bottom of the page for information on a "simple" wipe using the format command in Windows 11, Windows 10, Windows 8, Windows 7, and Windows Vista.
it usually takes around 2 hours to complete a 1TB internal hard drive; if the hard drive is connected via USB 2.0, then the time might be around 4 hours. Wiping a hard drive means overwrite all sectors of the hard drive with zeros or random characters, which takes time.
How many times should I run disk Defragmenter?
Defragment at Least Once per Month
As a general rule, any time your disk is more than 10 percent fragmented, you should defrag it. In Windows 10, Windows 8, and Windows 7, you can schedule defragmentation to happen as often as necessary.
It is best to let it complete the entire defragmenting process. If you stop using the defragmenting program, the disk will become more fragmented over time. Disk defragmenting programs usually have a built-in scheduling feature so you can schedule it to run periodically in the background to keep the disk defragmented.
Disk Defragmenter might take from several minutes to a few hours to finish, depending on the size and degree of fragmentation of your hard disk. You can still use your computer during the defragmentation process.
Power Loss. Your computer is relocating data on the hard drive by erasing it and rewriting it during a system defragmentation. If the computer loses power during a defragmentation process, it can leave parts of files incompletely erased or rewritten. This causes the files to be corrupted and they may not be recoverable ...
Cancel a Format via File Explorer. If you initiate the formatting process via Windows File Explorer, you will see the formatting window and there is a "Cancel" button available for you in it. You can click the button to stop the formatting process.
Usually, the more capacity a hard drive has, the longer time it will take to format. A full format will take a longer time than a quick format. This is because a quick format only deletes data from a partition, and then rebuild the file system, volume label, and cluster.
A full format erases any files from the disk, changes (or maintains) the file system and checks the disk for bad sectors. A full format takes significantly longer than a quick format.
To permanently delete files on Windows, send them to the Recycle Bin and then empty the Recycle Bin to delete them for good. Once the bin is empty, you can't recover the files unless you have data or file recovery software.
NOTE: Wiping your hard drive is an advanced procedure.
If you don't feel comfortable doing it yourself, you can schedule an appointment to bring your computer into a Best Buy store and have a Geek Squad Agent handle the process for you.
Defragmentation puts those separated pieces of data back together again. The result is that files are stored in a continuous manner, which makes it faster for your computer to read the disk and retrieve the files you need, increasing the overall performance of your PC.
Does defrag reduce life expectancy?
Myth-Busting Hard Drive Defragmenting
The idea behind that statement is that since you are rewriting files to the disk when you defragment, you are putting more wear and tear on the hard drive than necessary, thus shortening its lifespan. This is simply not true.
You will know if the defragging process is finished when the running progress report stops and the entry in the Current Status column becomes “o*k.” Enclosed in parentheses beside “o*k” is the percentage of defragmentation (0% if your hard drive is not too full).
