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
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.

4. Is it possible to reuse HDDs and SSDs?
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.
