## What is Bit Rot protection?

Bit Rot, also known as data rot or silent data corruption is a data loss issue faced by disk drives today. Data on the drive may silently get corrupted without signaling an error has occurred, making bit rot more dangerous than a permanent hard drive failure.

						qst, err = bfs.SysBlockDeviceQueueStats(parentDev)

				if err == nil {
					info.NRRequests = qst.NRRequests
					rot := qst.Rotational == 1 // Rotational is '1' if the device is HDD
					info.Rotational = &rot

// GetDriveStats returns IO stats of the drive by its major:minor
