Con quale programma verificare in modo completo l'hard disk HDD usato dopo l'acquisto?

Good advice first, then answer your question after advice. Why HDD??? 18 giga will copy for several hours It is not profitable to buy HDD, because they are too slow and everyone is getting rid of them now. And the sites with the 18 TB disk are 2020, then SDD was still expensive, now it is much cheaper. We should start testing the hard drive by reading this information - it's best to use the free CrystalDiskInfo or HD Tune tools for this purpose . CrystalDiskInfo is one of the most popular programs for testing HDD and SSD drives.

You can use hard disk diagnostic programs such as CrystalDiskInfo, HD Tune or HDDScan. Each of these programs can provide information about the state of the disk, including the amount of working time, the number of writes and reads, the presence of bad sectors, temperature and other important parameters.

You can use a data recovery tool like Recuva to check if the drive has been erased. You can use this tool to check if there are remnants of deleted files on the disk :)

1.CrystalDiskInfo - a program that allows you to read information about the state of the disk, including its working time. After starting the program, select the disk you are interested in and check the value in the "Power On Hours" field.

2. CrystalDiskInfo or programs such as HD Tune or HDTach - allow you to read information about the amount of written and read data. For CrystalDiskInfo, this value is in the "Total Bytes Written" and "Total Bytes Read" fields.

3. You can use Recuva to check if the disk has been formatted or erased. This program allows you to recover deleted files, so if the search results show files that we have already deleted, it means that the disk was formatted or had data erased.

4. You can use CrystalDiskInfo or HD Tune to check if your hard drive is healthy and has bad sectors. These programs allow you to read information about the state of the disk, including the number of bad sectors. If this number is zero, the disk is healthy.

No diagnostic program will answer questions 1-3, because the HDD does not have such counters built-in. The answer to the 4th question is important and there are countless tools here. Pretty good Linux - free.

The best option is the tool provided by the manufacturer. Major drive manufacturers like Western Digital or Seagate have a tool that can be downloaded from their website. Depending on the product segment (Server, Video Survillance, Home, etc), the corresponding utility will give more or less exhaustive results.

The best solution will be CrystalDiskInfo, this program I use and recommend it myself
