Hard drives are one of the most important components of computers, as they store the data we use every day. Since their invention until today, they have evolved rapidly, both in terms of their storage capacity and speed. This article will examine the historical review of hard drives, the problems they can face and ways to deal with these problems.
Chronology
The history of hard drives begins in 1956, when IBM introduced the first hard drive, the IBM 350 Disk Storage Unit. This drive had a capacity of 5 MB and consisted of 50 metal platters with a diameter of 24 inches. This technology was revolutionary for its time, but hard drives were large and expensive.
During the 1970s and 1980s, hard drives began to become more affordable and smaller in size. In 1980, Seagate introduced the ST-506, the first personal computer hard drive with a capacity of 5 MB and a diameter of 5.25 inches. From then on, the technology began to evolve rapidly.
In the 1990s and 2000s, hard drive capacity increased dramatically while their dimensions decreased. 3.5-inch drives became the standard for personal computers, while 2.5-inch drives dominated laptops. At the same time, new technologies were developed, such as SSDs (Solid State Drives), which use flash memory instead of mechanical parts, thus offering greater speeds and reliability.
Hard Drive Problems
Hard drives, despite their advancement, are not invulnerable. Some of the most common problems they can face include:
Η writing and reading from the heads of the hard disk is done while it rotates at high speed and is magnetic, i.e. the read-write heads do not come into contact with the magnetic material where the data is written.
Nevertheless, because the distance between the heads and the magnetic material of the disc is very small, it is very possible that bad sectors will be created at some point in time due to misuse and also due to the physical wear and tear of the mechanical parts.
Usually the appearance of Bad sectors also signals the impending death of the hard disk and it is completely useless to try to keep a hard disk "alive" whose death is now predetermined and certain.
For example, for a hard disk that works for many hours at high temperatures, you greatly reduce the life expectancy set by the manufacturer, which is generally several thousand hours of work depending on the disk.
A damaged or problematic disk on our computer is a potential ΄΄time bomb΄΄ for our computer in the sense that we are at risk of losing all our data at any moment in addition to the various problems that may occur (unexplained crashes, sudden restarts etc.)

However, it should be known that the average lifetime of a disc ranges from approximately 3-5 years depending on its use and manufacturing quality.
Addressing Problems
To avoid or deal with hard drive problems, we can follow some basic practices:
1. Backup: It is vital to regularly back up your data. This can be done via external drives, network attached storage (NAS), or cloud services.
2. Use disk health check software: There are many programs that allow you to check the status of hard drives and predict possible failures.
3. Avoid overheating: Good cooling of our computer is important to prevent overheating of hard drives. Use fans and cooling systems to keep temperatures at safe levels.
4. Avoid shocks and drops: Especially for laptops, it is important to avoid shocks and drops that can damage hard drives.
5. Replace old drives: If your hard drive is old and starting to have problems, consider replacing it with a newer and more reliable drive.
Ways to fix it
Of course, there are programs that can fix the bad sectors on our hard disk, but the very good ones (of professional specifications) are very expensive and for the average user it is a free gift since it will cost him less to buy a new hard disk than to repair it.
You should know that repairing Bad Sectors is not a panacea method that guarantees us the absolute repair of the problem but it may be a temporary and necessary action that we must resort to in order to save our data and transfer it to another new one hard drive that we should definitely buy.
There are several free programs with which we can determine whether our hard disk has bad sectors, but almost no free ones that repair them with absolute reliability.

(Actually no repair is done, it just marks the allocation table of the disk so that they are not used again).
Therefore, the golden rule to keep hard drives alive as long as possible is the least possible stress (reading, writing, low, dropping, knocking, high temperatures (the temperature of the hard drive should not exceed 50- 55 degrees Celsius).
Free repair apps
One of the best and most reliable free programs to see if your hard drive has Bad sectors is Disk Scanner with the help of which you can thoroughly examine your hard drive for problems, the application does not need installation and can run on all windows. A few more free diagnostic programs I could single out are the HDDScan, This makes it a perfect choice for people with diabetes and for those who want to lose weight or follow a balanced diet. Macrorit Disk Scanner and HardDiskValidator.
