As a rule of thumb, I'd deduct at least 50% depreciation per year. It's actual worth is dependent upon how old it is, what condition it is in, and how many hours it has actually been in use. Hard-drive manufacturers typically provide an MTTF (mean time to failure) expressed in hours. This is the average number of hours of continual use you can expect to get from a hard-drive before it is expected to fail. It is not an exact science, it is merely a guide figure, however, the closer a drive gets to its MTTF the less worth it has. Personally, I treat all second-hand drives with suspicion as it's hard to tell its true condition just by looking at it. You need to install it, inspect the SMART (self-monitoring and reporting tool) information, possibly reconfigure its geometry and soak test it for a week or two before deciding if its really fit for purpose. Even then, there's no guarantee it won't fail the moment you pay for it. At least if its an out-of-box failure you can get it replaced. You just don't get that sort of guarantee with a second-hand drive.

There are only three reasons that I know of. The first is: the hard-drive has to much memory for the computer to handle. The second is: The hard-drive and/or your computer in infected with a virus. The third is: The hard-drive is fairly new, while the computer is fairly old. I hope these helped!
Yes, if there is no operating system on the new drive, then your computer will not run.
A new hard drive can be found at computer stores, or directly from the manufacturer. The hard drive can be found on the Internet with a simple search.

It is best to wipe the hard drive before you remove it from the first computer and do a new install for the new computer. Then add your operation system.
Hard drives can make a big difference in computer performance. Consider a solid-state drive if you need quick drive access.

You do not need to "initiate" a hard drive. If the hard drive is installed correctly, Ubuntu will detect it.
# Turn the computer over, and remove the hard drive screws. # Slide the hard drive out of the computer. # Remove the new drive from its packaging. # Use firm and even pressure to slide the drive into place. If you use excessive force, you may damage the connector. # Slide the hard drive into the bay until it is fully seated. # Replace and tighten the screws. # If the new hard drive is not already pre-imaged, install the operating system and drivers for your computer
