Deletion Process

This chapter addresses potential issues and you may encounter during the deletion process.

Read, Write or Verification Errors

When HDShredder reports errors, it is usually the result of defective areas on the corresponding disk. General hardware problems can also cause read and write errors, which are usually indicated by a very high number of errors. In this event, cancel the deleting process, connect the affected disk to another port, or check it for defects. Then restart the deleting process.

Note: If disks are connected by USB, use another USB port and ensure sufficient power supply. When using USB cases for SATA or IDE hard disks, first check if the case is working properly.

Deletion Speed

Should the speed indicated by HDShredder not reach the expected value, please consider the following:

• Is the disk functioning properly? Please use the SpeedTest app to check if the disks achieve the expected speed, or which one shows a lack of transfer speed.
• When using USB cases for SATA and IDE hard disks, please note that the maximum transfer speed is much lower for USB 2 than for SATA or IDE.
• When using USB3 devices, ensure that they are connected to a USB 3 connector (blue). While in fact USB 3 devices are downward-compatible, yet they only run at USB 2 speed when plugged to a USB 2 connector (black).
