How many sanitizations/licenses of east-tec DisposeSecure should I buy in order to erase all hard disks connected to a computer/server?

A single sanitization allows you to erase 1 (one) entire hard disk or partition a single time. If the computer has 5 hard disks attached, you need 5 sanitizations. If the computer has 1 hard drive and you want to sanitize it 5 times, you also need 5 sanitizations. Therefore, it is important to know the number of hard disks you want to completely erase and the number of times you want to erase each hard disk.
