About Deleting Data

Do you think that emptying the Recycle Bin will permanently delete files?
Do you think that formatting hard disk will permanently erase hard drives' data?
Actually, neither erasing files by emptying the Recycle Bin nor formatting hard drives will destruct data permanently.

Why aren’t they erased?

For example, to erase a file on Windows by emptying Recycle Bin means just to put information of "ERASED" in the index area. Data itself remains in the data area without being erased. Unfortunately, the file can be easily recovered and viewed by data recovery software within a few minutes.
Please try our data recovery software, DataUndeleter to see if erased files on Windows can be recovered. (You can verify it by DataUndeleter demo version. *Demo version can find the to-be-recovered data but cannot save the recovered data.)

So if you want to sell, donate, discard, or return your computer, you need to make sure to eliminate your confidential information such as:

•	ID and Password	•	Social security number
•	Financial Documents	•	Human resources data
•	Tax Records	•	Corporate Trade Secrets
•	Bank account	•	Customer database
•	Credit card numbers	•	And more

How to erase data permanently

To erase a file permanently, you need to overwrite data (for example, 0x00, 0xff, random value, etc) on its index and data areas. Normally, even if you simply overwrite zero (0x00) on a file once, the data cannot be recovered by any data recovery software. But unfortunately the data overwritten once or twice can be recovered by magnetization pattern analyzers such as Magnetic Force Microscopy (MFM). In general, to erase data completely, it is recommended to overwrite data at least three times.

BluestSoft DiskDeleter supports DOD5220.22-M, which is the guideline published by the US Department of Defense for erasing magnetic media to guarantee that all data previously contained on that magnetic media is deleted permanently.
DOD 5220.22-M overwrites data total three times, first by 0x00 once then its compliment value 0xff once, and finally random values once. After the final process is complete, the disk is read to verify data to make sure there is no lingering pattern.

To protect your confidential information, BluestSoft DiskDeleter guarantees to permanently erase hard drive data on your computer with the following 6 methods, including DOD 5220.22-M.
1. Zero Write
2. Random Write
3. Random Random Zero
4. DOD 5220.22-M
5. NATO Standard
