I can’t save the file! How to solve when an HDD or an SSD runs out of the capacity

As you use your PC, various data and files will be accumulated. Not only files such as Word, Excel, and images, but also installing an update program when updating software fills capacity of an HDD and an SSD, and the operation of a PC becomes slow and unstable. So what should you do if your HDD or SSD runs out of space? This content introduces a method to solve an HDD or an SSD capacity shortage using a Windows PC as an example.

1. Delete unnecessary files
2. Disk cleanup
3. Move old files to external media
4. Conclusion
Although a huge amount of data files are stored in a personal computer, not all of them are used all the time, and some of them may not be used over time. In such a case, try increasing a free space on an HDD or an SSD using the method explained this content. However, if the capacity is still insufficient, consider adding more HDDs and SSDs, or replacing a PC with the one equipped with a larger capacity of an HDD or an SSD.

[TOPIC] HDDs and SSDs security measures: Let’s learn encryption

HDDs and SSDs security measures Let’s learn encryption

When taking a PC or an external HDD outside, information leakage countermeasures are important. In fact, there are many cases of loss or theft due to misplacement, and if that happens, important data in an HDD may be leaked. Especially in the case of companies, since confidential information and personal information are often handled, if information is leaked, it may lead to major problems such as credit loss and compensation. To prevent this from happening, let’s thoroughly implement security measures for HDDs and SSDs. This content introduces encryption.

What to do if you hear an abnormal noise from the HDD?

If you use a same computer for a long time, you may hear strange noises from the internal hard disk. If you hear the sound for the first time, you may think that it is temporarily in bad condition and leave it as it is. However, the abnormal noise of a hard disk can be a precursor to failure. So as not to be too late to deal with, keep in mind what to do if you hear a strange noise. By the way, in case of an SSD, since it is a type of memory, there is almost no noise. However, instead, data may suddenly become unreadable or the drive itself may become unrecognizable without any warning. Therefore, be especially careful when using it, and make sure you learn what to do in the unlikely event.

2. What to do if you hear an abnormal noise from a HDD
2-1. If a PC can still be started normally
2-2. If data is corrupted
2-3. If your PC does not start
3. Conclusion
HDDs and SSDs are consumables. Therefore, if you continue to use it for a long time, it deteriorates and eventually breaks down. For example, HDDs are generally supposed to be replaced about 2 to 3 years. However, some stop working within one month after purchase, and some can be used even after 10 years. Therefore, it is also important to periodically start dedicated software such as CrystalDiskInfo and check the S.M.A.R.T information in order to grasp the possibility of failure in advance.
* “S.M.A.R.T information” is a numerical value that manages health status of an HDD or an SSD by a diagnostic function of the HDD and SSD itself. It is very important to learn how to deal with an abnormal sounds from an HDD or an SSD in advance so that you will not be in panic.
