One of the most important components of a computer is the hard drive. This is where all the necessary information, pictures or videos are stored. Many people use extra hard drives for hobby or work, which is known as external or portable hard drive. Many people buy old external hard drives to reduce the cost. Even if the price is low, there is a risk of being cheated by buying an old hard drive. For this, before buying an old hard drive, please check the following issues.
1. The capacity of the hard drive depends on the speed of work. Hard drives with revolutions per minute higher than RPM work faster. So when buying, be sure to look at the power of RPM. Hard drive RPM usually ranges from 5,400 to 10,000. The higher the RPM, the higher the price.
2. No matter how old the old hard drive may look, it must be tested by connecting it to a computer. At this time, if you send a file from the computer to the hard drive, you have to see if it is saved. It is best to test whether the hard drive is capable of storing data according to its capacity. If data cannot be stored as per capacity, then some part of the hard drive is not working. It is best to delete the entire hard drive once the data is filled. This will make sure that there is no problem inside the hard drive.
3. The power supply plug must be thoroughly tested. Many times used hard drives have problems with the power supply. You must be sure about this before buying a hard drive.
4. It is important to know if the hard drive has an after-sales service period. If not, find out how many days after the after-sales service has expired. It is better not to buy a hard drive that has expired a long time ago. If after-sales service is available from any organization, its valid paper must be collected.
5. It is important to check for any signs of injury or stains on the outside of the hard drive. Also, you need to know if the hard drive gets hot while it is running. Hard drive temperature can also be known with the help of apps made by different organizations. Temperatures up to 50 C are generally safe for hard drives.
