The utility allows you to test the read and write capabilities of a hard drive or any other block device, visualizing the process, similar to the DOS utility MHDD or Victoria.
The utility has a media copy function, which is optimized for fast data extraction with minimal wear on an already damaged media.
The utility can work with a hard drive at a low level, by sending ATA commands to the device, which allows you to get the following advantages:
- The system does not hang from accessing a faulty zone, which happens when working with the standard POSIX API open()+read() (after a timeout, a soft reset command is sent to the device);
- More accurate measurement of the disk speed.
