You can restore all files of different types or filter searches by format. Uneraser is equipped with many functions that will satisfy even the most demanding customers. This program has been an unchallenged leader in the market for more than 15 years. If there is any data that you want to save, save it before defragmenting using the DiskInternals Uneraser data recovery and export application. If the external hard drive is your indispensable assistant and it is at work every day, fragmentation is recommended. It is also worth noting that defragmentation is not always necessary if the external hard drive is rarely used in such a case, you will not notice any difference before and after this procedure. Therefore, turn off the automatic defrag function and forget about this method of increasing productivity.

The fact is that for SSDs, it is useless moreover, the lifespan of such a disk will decrease a lot after defragmentation. The answer to this question is: if you have an HDD, defragmentation is worthwhile, but if you have an SSD, it is not. Therefore, for guaranteed improvement in the operation of your hard drive, it is recommended to periodically defragment it. In recent versions of Windows, this function is performed automatically, but not always. To defrag an external HDD will speed up such a disk. This leads to longer data processing since it is difficult to find the necessary information due to “gaps”. Naturally, during the operation of the disk, you will delete unnecessary files, and after removal of the external disk, there is empty space. When you save data to external media, it is automatically distributed across clusters. To understand why you need to use defragmentation on external disks, you need to understand the essence of this procedure. Defragmentation and external HDD performance Therefore, anyone can optimize their disk without much effort. Programs for defragmenting drives have recently undergone significant development, making them both considerably more sophisticated and user-friendly. Yet, it greatly enhances disk performance. Regular disk defragmentation was not always achievable this was partially due to a lack of time because defragmentation is a time-consuming operation. Up until recently, most users found defragmenting both internal and external hard drives to be laborious, challenging, and unpredictable.
