What is “ATA Password Lock” to prevent theft or loss of HDD / SSD or PC?

It is common for personal information and confidential company information to be stored on an HDD or SSD built into a personal computer. Therefore, if your computer is stolen or lost, important information may be extracted from the HDD or SDD. In case of theft or loss, it is important to take measures in advance so that the contents of the HDD or SSD cannot be seen by others. One method is “ATA password lock” introduced this content. However, since this ATA password lock is a very strong security feature, if you use it incorrectly, you may not be able to access your data yourself. Let’s learn how to use it correctly in this content.

4. Conclusion
If you lock the ATA password, you no need to worry about your data being seen by others even if your computer or HDD or SSD is stolen or lost. However, since the data is recorded unencrypted, it is easy to see if the password is known. Also, if you forget the password, not only you lose the data, but you are not be able to use the HDD or SSD itself. Be careful.

How can I retrieve data when an HDD or SSD is no longer recognized?

In some cases, when using a PC, it suddenly stops starting one day, or the startup stops halfway and you cannot proceed further. Such cases occur when an OS such as Windows is damaged, or when a part of an HDD or SSD is damaged and normal reading cannot be performed. The other cases, an external HDD or SSD cannot be read. In both cases, the data may be safe at the initial stage. If these happens, follow the steps below to retrieve your important data before it is lost.

1. An internal HDD / SSD
2. An external HDD / SSD
3. Conclusion
As you can see, how easily data can be retrieved from an HDD or SSD depends on whether it is physically damaged. If you are not confident that you can take it out yourself, consult with a store where you purchased it or a nearby PC shop. And since it takes time and effort to remove an HDD or SSD from the main unit or purchase parts to retrieve the data, it is still the best preventive method to keep a backup.
Not only HDDs and SSDs, but also DVDs and USB memories can be used. So it is important to copy your data to another medium anyway. One option is to use a cloud service that automatically makes backup online. HDDs and SSDs are consumables and no one can predict when they break. Always keep a backup in case of an accident.

What is the proper disposal method when a used PC or external HDD / SSD is no longer needed?

It is said that the life cycle of a PC today is three years. As the price of PCs drops rapidly, it may be common for manufacturers to design with a durability of about 3 years. For individual use, it may be used for a little longer though, for companies, it often takes about three years to replace it with a new model. If you buy a new PC, you may dispose of the old PC, however the PC has an internal HDD or SSD that contains your important data. If they are thrown away without data erase, they may be extracted by someone and may be misused. This content introduces how to properly dispose of used PCs, external HDDs, and SSDs.
1. How to properly dispose of a PC
2. What if you want to dispose of an external hard drive or an SSD
3. About HDD data erasure
4. Is it possible to reuse HDDs and SSDs?
5. Conclusion
Since various data is stored in either an HDD or SSD built into a used PC or an external HDD or SSD, it is not recommended to throw it away unnecessarily. Even if you erase the data on the surface, it may be restored by using special software or technology. Be sure to completely erase the data at your own risk. Or, if you cannot do it by yourself, ask a reliable specialist. Occasionally, you may try to puncture or destroy an HDD or SSD yourself with a hammer or drill, however since this is dangerous and may not lead to complete data erasure, it is not recommended.
For companies that process a large number of HDDs and SSDs in a year, using a device such as an HDD destroyer help you safely destroy them.

What to do if an HDD or an SSD does not boot?

One day, when you turn on your PC to work, you wonder why it does not start. In this case, there are several causes though, most of the time it is a temporary malfunction and may starts when you turn it on once again. Also, in reality, there are quite a lot of cases where an SD card, external HDD, and USB memory are left inserted and read before an HDD of the main unit. Depending on a settings of a PC, if they are inserted, they will be read preferentially, but of course they do not start because there is no OS such as Windows, and they stop with a black screen. (A few years ago, floppy disks were often left inserted in similar cases.) If these are the causes, you don’t have to rush because an HDD of the main body will start normally if you unplug everything inserted in the main body of the PC and turn on the power again. However, if these are not causes, but an HDD or SSD built into a PC does not boot, there is a little troublesome problem. This content explains such a case.

1. An internal HDD does not start! An internal SSD does not boot!
1-1. Case 1: When an OS such as Windows is damaged
1-2. Case 2: When an HDD or SSD is physically damaged
2. An external HDD does not boot
3. Conclusion
There are several reasons why an HDD and SSD do not boot, but as explained here, it is very difficult to rescue data due to corruption. An HDD and SSD have a limited lifespan, and it is not possible to know when they breaks, so it is important to keep a backup at all times. If you save the data in two or more places, such as the main unit and the external device, you can rest assured that the data will remain even if one of them breaks. Let’s make a backup of your data and photos so you don’t lose them.

Erased important data accidentally! HDD and SSD data recovery method

Many people have experience of losing data due to unexpected troubles or accidentally erasing important photos and files while using a personal computer. It is most important to always keep a backup in case of an HDD and SSD failure or trouble, however some of you might not have a backup in case of sudden trouble. If you want to recover some data that you have deleted, you may recover the internal data. This content explains how to recover an HDD and SSD data.

1. Recover data using software
1-1. HDD data recovery
1-2. SSD data recovery
2. Ask a professional contractor
3. To increase the probability of data recovery
4. Conclusion
Data recovery using software is not so difficult, so you may feel free to try it. However, this method works on only deleted files. When an HDD or SSD cannot be read in earnest, it becomes difficult to determine whether the cause is a logical failure or a physical failure. As mentioned above, if you can’t decide for yourself, it is better to ask a professional contractor as soon as possible.
