How To Fix A Slow External Hard Drive?

Your external hard drive probably pulls a lot of weight for you, storing backups, holding onto big files, and taking the pressure off your system’s internal drive.

Because external hard drives get used in so many different ways, it makes sense that they run into all kinds of problems. And among those problems, a slow external hard drive is one you’ll bump into more often than most.

Why is my external hard drive being so slow?

Fragmentation on older hard drives-

The longer you use your drive, the more data gets written and deleted on it. Over time, this can scatter your data into fragments spread across different parts of the disk, which drives up seek time and drags down load speeds.

File system corruption

Got corrupted files or folders? They might load painfully slowly, or refuse to open altogether. If you’re dealing with this, tread carefully, fixing a corrupted hard drive the wrong way can make things worse.

Connection issues

A bad cable or a flaky port can tank your drive’s performance all on its own, leading to sluggish load times and random disconnects.

Outdated drivers or firmware

Your drivers and firmware play a bigger role in your drive’s performance than you might think. Let them get outdated or buggy, and you could end up with a whole range of issues, slow HDD performance included.

Device overheating or hardware issues

If your external hard drive is getting up there in age (5+ years) or hasn’t been looked after, you might be looking at actual physical damage that’s dragging down performance. Overheating, or scratches and dents on the drive’s exterior, are usually a good sign that’s what’s going on.

Solutions To Fix a Slow External Hard Drive

Preparation Task list

Before you jump into the fixes below, knock out these tasks first, it’ll get you better results.

1. Update Windows.

2. Update your drivers and firmware.

3. Test your hard disk on another computer.

1. Connectivity Issues

Start by ruling out the hardware. Take a close look at the ports and cables you’re using. Swap in a different cable, try another port, or plug the drive into a different system altogether and see if the results change.

2. Run Diagnostic Checks

You’ve got a few tests you can run to check your external hard disk health. These won’t just confirm there’s a problem, in some cases, they’ll fix it for you too.

1. Windows Error Checking Tool

The Windows Error Checking Tool is a quick way to run a basic diagnostic. It’ll scan your drive for file system errors or inconsistencies.

1. Open Windows File Explorer and head to This PC.

2. Right-click your external hard drive and pick Properties from the drop-down menu.

3. Go to the Tools tab and click Check.

2. CHKDSK

CHKDSK is a command you can run to check your external hard drive for file system corruption, bad sectors, and similar problems. It can look a bit intimidating if you haven’t used it before, but just follow the steps below and you’ll be fine-

1. Type “Command Prompt” into the Windows search bar, then choose Run as Administrator.

2. Type “chkdsk B: /f /r /x” and hit Enter.

(Swap B for whatever drive letter your external hard disk actually uses)

/f- Scans for errors and fixes them.
/r- Scans for bad sectors, fixes them, and recovers whatever readable data it can.
/x- Forces the drive to dismount before the scan and fix runs.

3. Defragment External Hard Drive

Defragging your external hard drive reorganizes the data sitting on it, which streamlines things and can give your drive’s speed a real boost. Here’s how to do it-

1. Open Windows File Explorer and head to This PC.

2. Right-click your external hard drive and pick Properties from the drop-down menu.

3. Go to the Tools tab and click Optimize.

4. The Optimize Drives window will pop up, make sure your disk is selected, then click Optimize.

4. Format External Hard Drive (Last Resort)

Formatting is a drastic move. It wipes every bit of existing data off your drive and brings it back to a clean, mint state (logically speaking). Once you format, all the data on that drive is gone.

PART 1: Recover Data From Slow External Hard Drive

Before you format, you’ll want to pull your existing data off the drive first. If you’ve got a lot of data and your external hard drive is really dragging, there’s a decent chance of corruption during the transfer. That’s where professional data recovery software comes in.

SFWare Data Recovery is built for exactly this kind of job. Thanks to its advanced algorithm and simple interface, you’ll be able to recover data even from a badly corrupted hard drive without much hassle.

Note: Make sure you’ve got another healthy external hard drive on hand to store everything you recover.

1. Plug both the slow external hard drive and a healthy one into your PC.

2. Download, install, and open SFWare Data Recovery.

3. Select the slow external hard disk and click Start Scan.

4. You’ll see a list of all the files and folders it’s recovered.

5. Preview the results and select whichever files and folders you want to keep.

6. Pick the healthy hard disk as your destination and hit Save to store the recovered data there.

Once your data is safely tucked away on the healthy drive, you’re ready to go ahead and format the slow one.

PART 2: Format Slow External Hard Drive

(Double-check that you’ve recovered everything off the slow external hard drive before moving forward)

1. Open Windows File Explorer and head to This PC.

2. Right-click your external hard drive and choose Format… from the drop-down menu.

3. Pick a file system (NTFS is recommended) and click Start.

Now just move your recovered data back onto the newly repaired hard drive, and you’re free to use it like normal.

How do I make my external hard drive faster?

Check the USB port first. Plugging a USB 3.0 drive into a USB 2.0 port caps your speed at around 35 MB/s no matter what the drive is capable of. USB 3.0 ports are usually blue inside, or marked with an SS icon next to the port. If your drive supports USB 3.1 or 3.2 and you are still getting USB 2.0 speeds, the cable is the usual culprit, not the port.

Power settings matter more than people expect. On Windows, open Control Panel, go to Power Options, click Change plan settings, then Change advanced power settings, and check USB selective suspend setting. Set it to Disabled. Windows uses this setting to save battery by powering down idle USB devices, and it can make an external drive feel like it is lagging every time it wakes back up.

Beyond that: update the drive’s firmware from the manufacturer’s site rather than relying on Windows Update, keep at least 10 to 15% of the drive free since near-full drives slow down dramatically, and if the drive uses exFAT, know that exFAT has no journaling, so a bad disconnect is more likely to corrupt data than it is on NTFS. None of this requires third-party software. If speeds are still poor after all of it, the drive itself is probably the bottleneck, not your settings.

What are the signs of a dying HDD?

Clicking is the one everybody recognizes, and it means the read/write head cannot find a stable track. Stop using the drive immediately if you hear it. Grinding or repeated loud clunks during spin-up point to the same kind of mechanical failure.

Less obvious signs show up first, though. Files that take noticeably longer to open than they used to. Folders that freeze File Explorer for several seconds before showing contents. Random disconnects where the drive drops off and reappears in Disk Management without you touching the cable. S.M.A.R.T. attributes like Reallocated Sector Count or Current Pending Sector climbing above zero are a reliable early warning if you check them with a diagnostic tool before symptoms get loud.

A drive that is overheating to the touch after twenty minutes of light use is also a bad sign, especially on drives over four or five years old. If you are seeing two or more of these together, back up what matters that day. Do not wait for a full diagnostic scan to confirm it. If the data is already something you cannot afford to lose, this is the point to recover data from external hard drive rather than keep troubleshooting speed.

What is the lifespan of an external HDD?

Three to five years of regular use is the realistic range for a mechanical external HDD, though plenty run past that with no issues. Backblaze’s annual drive stats, drawn from well over 200,000 drives, put average annualized failure rates around 1 to 2% in the first few years, climbing noticeably after year four. Drives that sit in a drawer and get powered on occasionally often outlast ones left running constantly, since heat and vibration during use are what wear down the bearings and the read/write mechanism.

SSDs in external enclosures age differently. They do not have moving parts to wear out, but NAND flash has a limited number of write cycles, so an SSD used for constant heavy writes can degrade faster in terms of write speed, even if it never fails outright.

Age alone is not the only predictor. A drive that is three years old and has been dropped twice is a worse bet than a seven-year-old drive that never left a desk.

To Conclude

Hopefully this got your slow external hard drive back up to speed. Staying on top of your hard disk’s health really does save you headaches down the road. Got feedback or questions? Don’t hesitate to reach out.
