What is the difference between secure erase and sanitize?
Secure Erase is different from Sanitize because it only deletes the mapping table but will not erase all blocks that have been written to. Sanitize will delete the mapping table and will erase all blocks that have been written to. Therefore, Secure Erase is faster to complete than Sanitize.
Secure erase procedures are designed to delete everything beyond recovery, so if you forget something, chances are you won't be able to get it back using any conventional form of recovery software.
When the drive is SANITIZED (wiped clean) using the Crypto Erase option, the HDD deletes the internal key, rendering data unreadable. Overwrite is a secondary erasure method for HDDs. It erases the drive. by overwriting existing data with a bit pattern. This method erases the.
Most experts agree that Secure Erase is the best way to overwrite an entire hard drive in a single pass. The very simple Write Zero method accomplishes essentially the same thing, albeit much slower.
Secure Erase is a feature that was initially designed for HDDs, or hard disk drives. However, it can also be used with solid state drives, or SSDs, which are now more common. Secure Erase completely wipes clean all of the data found on a drive and does not allow that data to be retrieved.
Wiping programs like DBAN have a hard time identifying all the far-flung data blocks, so they don't do a good job of secure deletion on an SSD. Standard secure deletion tools damage SSDs by performing an unnecessary number of additional writes without being able to tell where the data is written.
Choose the drive from the listed storage devices. Step 6. And this program will warn you that this operation will erase all data on the hard drive, confirm the operation and click “Continue”. After a few minutes, the hard drive will be erased.
When you use ATA secure erase it is not wiping the whole disk. It is removing the encryption keys on the drive controller, which are used to transparently encrypt data before it is written to the memory chips. Removing this key is virtually instantaneous as you have discovered.
- BEFORE YOU BEGIN.
- STEP 1: Remove the hard drive from your computer.
- STEP 2: Access the hard drive's platters and circuit board.
- STEP 3: Remove the read/write arm, and scratch the platters with a screwdriver to destroy data.
- STEP 4: Break the circuit board.
- STEP 5: Recycle the computer's components.
There are three methods to achieve data sanitization: physical destruction, cryptographic erasure and data erasure.
Is 7 pass erase secure enough?
A single pass with zeros doesn't completely erase magnetic artifacts from a disk. It's still possible to recover the data from the drive. A 7-pass erasure using random data will do a pretty complete job to prevent reconstruction of the data on the drive.
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.
If what you have is a Samsung 830, 840, or 850 series SSD, you can use Samsung SSD Magician to perform Samsung SSD Secure Erase. “Secure Erase” is a safe way to reset your SSD to the factory default performance and all the data can never be recovered even with most data recovery services.
The Sanitize operation is a very useful tool for SSDs as it is used to eliminate information on a device that may contain personal data or confidential information. Elimination of personal information is important when returning or re-purposing an SSD.
Besides, it supports “Wipe Partition”, which only erases the data on one selected partition, allowing you to wipe a hard drive without deleting Windows OS.
Conclusion: Only 1 Overwriting Pass is Needed to Erase HDDs
Multiple overwriting passes for hard disk drives is not an absolute necessity anymore. So, how many times should you overwrite a hard disk for complete data erasure? The answer: One pass is enough.
After the hard drives are shredded, they will send you a certificate of destruction. If you have over ten hard drives, they will charge \$12 per hard drive. The disks need to be removed prior to pickup. Some shredding companies will charge a much as \$50 per hard drive.
If you've ever watched the hit TV show 'Breaking Bad', you'll already know that yes, technically it is possible to destroy the data on a hard drive with a magnet. But you will also know that the magnetic force required to do will also destroy pretty much everything else around it – including the computer itself.
The number of write cycles, or endurance, varies based on the type of NAND flash memory cell. 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.
Go to Settings → Change PC Settings → Update and Recovery → Recovery. Under “Remove everything and reinstall Windows,” click “Get started,” then click “Next.” Select “Fully clean the drive.” This takes longer, but it's the most secure option. Click “Reset” to start the process.
How do I permanently delete files from my SSD?
Boot the drive and choose option 1, Default Settings. Once booted head to Start (bottom-left) > System Tools > Erase Disk. Choose the Internal:Secure Erase command writes zeroes to entire data area option, then confirm the drive you want to erase on the next screen.
- Turn on or restart the computer.
- While the display is blank, press the F10 key repeatedly to enter the BIOS settings menu. ...
- Select Security.
- Select Hard Drive Utilities or Hard Drive Tools.
- Select Secure Erase or Disk Sanitizer to open the tool.
It should take 2-5 hours. Your bottleneck is the disk, not the RAM, the CPU, the cables or controller configuration.
Calculating Time
In cases where a drive with a capacity of a terabyte will be wiped using the DoD-approved nine passes of randomly written ones and zeros, it is very likely that this process will take in excess of one month of 24 hours per day processing to finish this wiping procedure.
Based on an article in Apple's knowledge base, the button is intentionally disabled for SSD's because: Note: With an SSD drive, Secure Erase and Erasing Free Space are not available in Disk Utility. These options are not needed for an SSD drive because a standard erase makes it difficult to recover data from an SSD.
Another method to sanitize a drive is to physically destroy the hard drive platter with a hammer or destroy the silicon chip of the SSD by shredding it or otherwise physically destroying it. (Note: shredding the silicon might damage your shredder machine.)
Due to the way SSDs are constructed, attempts to destroy an SSD with a magnet or drilling holes into the chips can still leave data intact. “It's best to thoroughly destroy them with a hammer so all of the memory chips contained within are pulverized,” Bischoff noted.
Vinegar will destroy the data on a hard drive, but without extensive testing, it is not possible to be certain. The acidity of vinegar can corrode metal and other materials which are found in electronics and could cause structural damage to your laptop or phone if there is an excess amount of contact with the liquid.
When a hard drive gets wet, the water could potentially cause a short circuit, especially if it dries on the platters. But water alone will not destroy a hard drive or delete its data. While water can damage a hard drive's electronics, the data itself is stored magnetically.
Wipe It and Recycle
If you'd rather recycle the hard drive rather than physically destroying it, it is absolutely necessary to wipe it before dropping it at a recycling center. Wiping a hard drive destroys the data stored on it. To find out how to dispose of hard drives, you need a proven data destruction program.
What does it mean to sanitize data?
Data sanitization is the process of irreversibly removing or destroying data stored on a memory device (hard drives, flash memory / SSDs, mobile devices, CDs, and DVDs, etc.) or in hard copy form. It is important to use the proper technique to ensure that all data is purged.
Data sanitization involves purposely, permanently deleting, or destroying data from a storage device, to ensure it cannot be recovered. Ordinarily, when data is deleted from storage media, the media is not really erased and can be recovered by an attacker who gains access to the device.
1 : to reduce or eliminate pathogenic agents (such as bacteria) on the surfaces of (something) : to make (something) sanitary (as by cleaning or disinfecting) You can use sponges and dishcloths safely if you take care to sanitize them, says Dean Cliver, a professor of food safety at the University of California, Davis. ...
Eraser is a free data-destruction program that's able to wipe all the data off of an entire hard drive at once. Because it also can permanently delete individual files and folders as well, it's also a great free file-shredder program.
DoD 5220.22-M
It can be a long and taxing process as the storage device must be overwritten three times and verified continuously. After all the time and effort spent running the software wiping program and ensuring that it is effective, data can still be recovered from the drive.
The 3-pass DoE compliant wipe mitigates this by writing two passes of random data before setting the drive to a known state (likely by zeroing it). After this procedure, it should be impossible to recover data even by bypassing the drive's internal read/write hardware.
How long does a Gutmann wipe take? It needs to be estimated according to your drive size, for example, a 1TB drive should take around 10 hours to erase over USB 2.0. If you happened to do a Gutmann wipe, then that would take 350 hours, i.e. about 2 weeks.

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.
Degaussing won't work. A solid-state drive uses integrated circuit assemblies to store data, unlike traditional hard disk drives. The data on SSDs is virtually unaffected by the method of degaussing.
Defined in NVMe specifications, NVMe Secure Erase is part of Format NVM command that allows storage drives to erase all user data areas. The erase process usually runs on the firmware level as most of the NVMe-based storage media currently in the market are built-in with this command.
Press Windows Key + I, type recovery in the search bar, and select Reset this PC. Next, select Remove everything, then Remove files and clean the drive. The Windows 10 reset function can take a while to complete, but it will make sure there is no chance for anyone to recover data from your drive.
Open Settings > System > Recovery and click Reset PC. When prompted, choose Remove everything, just like in Windows 10.
Formatting a disk does not erase the data on the disk, only the address tables. It makes it much more difficult to recover the files. However a computer specialist would be able to recover most or all the data that was on the disk before the reformat.
If what you have is a Samsung 830, 840, or 850 series SSD, you can use Samsung SSD Magician to perform Samsung SSD Secure Erase. “Secure Erase” is a safe way to reset your SSD to the factory default performance and all the data can never be recovered even with most data recovery services.
hdparm will issue a low-level write (completely bypassing the usual block layer read/write mechanisms) to the specified sector. This can be used to force a drive to repair a bad sector (media error). -W Get/set the IDE/SATA drive´s write-caching feature. -X Set the IDE transfer mode for (E)IDE/ATA drives.
A single pass with zeros doesn't completely erase magnetic artifacts from a disk. It's still possible to recover the data from the drive. A 7-pass erasure using random data will do a pretty complete job to prevent reconstruction of the data on the drive.
It permanently deletes data from the hard drive and is not available for solid-state drives. Secure Erase: Works on solid-state drives and hard disk drives. HP added Secure Erase to the standard BIOS in 2011. Systems sold in 2009 or later can upgrade the BIOS to include Secure Erase.
