Will I be able to use my HDD again after Active@ KillDisk erases the disk?

All drives erases by KillDisk can be reused assuming the drive does not have any SMART issues.

We recommend you turn on the Initialization od disks after erasures to save yourself time:

However, to use the disks, you still need to partition them.

To be able to use HDD again you need to:

• Repartition HDD using a standard utility like FDISK/Built in Windows Disk Manager
• Reinstall an Operating System using bootable CD-ROM or USB if you wish to boot from the hard drive
