Hard drives are non-volatile, as you don't lose the data stored within if you turn off the power to them.
No, they are permanent storage devices, only RAM is volatile storage device.
Hard drives are not volatile storage devices, because the information within them is not lost when the drive loses power.
I believe that you mean to ask if hard disk drives are considered volatile storage media or not. Volatile memory is memory that is lost when the storage medium is not being supplied with electricity. Hard drives do not need power for storage, only for reading and writing data from and to the platters; this means that hard drives are not volatile storage media.
Storage that retains its data after the power is turned off is referred to as non-volatile storage. This type of storage includes devices such as hard disk drives (HDDs), solid-state drives (SSDs), and flash drives. Non-volatile storage is essential for preserving data over time, ensuring that information remains accessible even when the device is powered down.
SCSI is most commonly used for hard disks and tape drives, but it can also be used to connect a wide range of other devices, including scanners and DC drives.

Storage devices are different mediums that can hold varying amounts of information. Some examples of storage devices include CD, DVD, flash drives, floppy disks, and tape drives.
Examples of storage devices are: internal/external hard drives, floppy drives, CD's, DVD's, thumb drives, etc.
Solid state drives, or SSD, are storage devices that uses integrated circuit assemblies as memory. Flash drives, compact flash, and MultiMedia cards are examples of solid state storage devices.
There are many different kinds of storage devices based on the purpose of the device. These devices include flash drives.
When a PC is powered off, programs are stored on non-volatile storage devices such as hard drives (HDDs), solid-state drives (SSDs), or external storage. These storage mediums retain data even without power, allowing the operating system and applications to be loaded into the computer's memory (RAM) when it is turned back on. In contrast, the RAM is volatile and loses all stored data when the power is off.
