New Hard Drive Not Showing Up? How to Fix It

Sourced from real discussions on r/techsupport and r/buildapc, cross-checked against live PricePerGig listings.

Classic, you’ve bought a new drive, plugged it in and, where, where is it? The drive isn’t broken, it’s just not formatted. Manufacturers pre format the drive so it shows up, but if you’ve bought used/refurb or an enterprise drive, there is a good chance it’s not pre formatted.

A truly ‘blank’ disk drive won’t show up; a truly blank disk drive is akin to an empty room, and if you’re going to store books in there (your data) then you need some book shelves, or in this case a file system such as NTFS, exFAT or the older FAT32 or ext4.

On Windows you’ll want to use Disk Management Tools (if you’ve never seen this before and you’re getting into PCs you’ll find it fascinating) and that will show you every physical drive ‘connected’ to you computer, and then you can format the drives and they’ll show up right away.

If you can’t find it in Disk Management, then it really is broken, but only after you’ve checked and double checked the power and the data (SATA) connector.

To get to disk management, it’s getting harder with every release of Windows; it’s been the same since Windows 2000, but as we approach Windows 11 it really is getting hard to find exactly the same tool. With a bit of luck you can just press the ‘windows’ key on your keyboard, and type ‘disk manager’ and it will show up, but you’ll probably need to right click the Start button, or hold the Windows key and press X, then pick Disk Management from the menu that appears. Failing that, hold the Windows key and press R, type diskmgmt.msc and press Enter, which has worked in every version since Windows 2000.

The table above shows the live price per TB for hard drives of 8TB and up on your marketplace, just in case the drive really is faulty and you want a replacement.

Why a new drive is invisible at first

This catches almost everyone, so let me explain.

External USB drives usually arrive pre formatted, so they mount the moment you plug them in. Bare internal drives, and most used, refurbished or ex enterprise drives, do not. They ship with no partitions and no file system, a blank slab of storage with no structure on it.

Your file explorer only shows drives that are formatted and ready. So a raw, unformatted drive simply does not appear there, even though it is connected and working perfectly.

Nothing is wrong. The drive is just waiting for you to set it up.

The fix: initialise and format

This is the part that makes it appear, and it takes two minutes.

Open your operating system’s disk management tool. On Windows that is Disk Management, on a Mac it is Disk Utility, on Linux a tool like GParted.

In there, your new drive almost always shows up as unallocated or uninitialised space. From here:

• Initialise the disk if prompted.
• Create a new partition or volume on the unallocated space.
• Format it with a sensible file system.

Once that finishes, the drive pops up in your file explorer as a normal, usable drive. Job done.

If it does not appear even in disk management

If the disk tool cannot see it either, the problem is physical. Work through these.

• Check the data and power cables are firmly seated at both ends.
• Try a different cable and a different port.
• Inside a desktop, make sure the drive has power, listen for it spinning up.
• Test the drive on another computer if you can.

A drive that shows up nowhere, despite good cables and ports, on more than one machine, may genuinely be faulty.

When it is actually a dud

It happens occasionally. New drives can arrive dead.

If you have tried different cables, ports and another machine, and the drive is invisible everywhere, it is probably faulty.

That is what the warranty and return window are for. Send it back, and use the live prices above to line up a replacement.

The bottom line

A new drive not showing up is almost always just an uninitialised, unformatted drive doing exactly what it should. Open disk management, initialise, partition and format it, and it appears.

If it is invisible even there after checking cables and ports on another machine, it may be faulty, so return it and grab a replacement from the live prices above. Nine times out of ten though, it is a two minute fix and your drive was fine all along, no drama.

So remember, before declaring your disk a dud, get yourself into disk management, and always turn the PC off when connecting/disconnecting disk drives. If you have got a dud drive, hopefully you used the helpful ‘returns accepted ’ filter available on PricePerGig and you can just send it back no worries, if not you’ll need to contact the seller and go through the process.
