This category consisted of 5 dimensions: The one thing that I wish our company would do is wipe the hard drives before destruction while they are waiting to be destroyed. You never know when these records will come in handy.

Disk encryption before use prevents this problem. Everything I needed was recovered and sent back on a replacement disk.

Category B consisted of the write pattern used both for the initial write and for the subsequent overwrites. With the increase in the write density of hard drives, encoding schemes based on peak detection such as Modified Frequency Modulation or MFM that are still used with floppy disks have been replaced in hard drive technologies.
