Hard drives and SSDs almost never die without warning. The trouble is that the first warning is easy to shrug off. The sign our customers ignore most is slowness. The computer takes longer to start, files open a little slower, things freeze for a few seconds — and people put up with it for months. By the time it stops booting, recovering the files is harder and more expensive than it needed to be.
Here are the warning signs, in the order people usually notice them, and what to do about each.
1. The computer is getting slower (the one everyone ignores)
As a drive wears out, some areas become hard to read. The drive retries them over and over, and the whole computer waits. That shows up as slow startups, long pauses and freezes that suddenly "catch up." People blame Windows, a virus or the computer's age — but in our shop, a slow computer almost always has a degrading drive. More on that in why is my computer so slow?
Check it: on Windows, press Ctrl + Shift + Esc and look at Disk in Task Manager. If it sits at or near 100% while you're doing almost nothing, the drive is struggling.
2. Freezes, spinning wheels and files that take forever to open
Short freezes become longer ones. Opening a folder takes several seconds. Copying files stalls partway. This is the drive struggling to read damaged areas.
3. Files that won't open or come back corrupted
Photos that show up half gray, documents that say they're damaged, folders that are suddenly empty. Stop saving new files to the drive — new writes can overwrite what's still recoverable.
4. Clicking, ticking or grinding
On a mechanical hard drive, these sounds usually mean physical trouble inside. Shut the computer down. Running a clicking drive can damage the surface the data is stored on. (SSDs have no moving parts and don't make noise.)
5. Boot errors and a drive that comes and goes
"No boot device found," "Preparing automatic repair" loops, or a drive that shows up one day and not the next. At this point the drive is close to failing completely.
6. Health warnings
Some computers and drive tools report S.M.A.R.T. errors or "disk health" warnings. Take them seriously, but don't rely on them — plenty of drives fail without ever showing one.
How we test your drive — free
Every computer that comes in with these symptoms gets a complimentary drive test. We use several tools, most often HDDScan, which reads the whole drive and draws a heat map of it — healthy areas read fast, weak and failing areas show up as slow or bad blocks. You can literally see how close the drive is to failing. We also read the drive's own health data and tell you plainly what we found before any paid work.
What happens next
- Save the data first. If the drive is weak, we copy your files off before anything else. A backup of a failing hard drive starts at $150; a full backup and restore is $99.99.
- Replace the drive. Usually with a new SSD — faster and more reliable than the old hard drive. If the old drive is still readable, we can often clone it so your programs and settings come across exactly as they were.
- If the drive has already failed, we'll explain your data recovery options and costs before attempting anything. See hard drive failure recovery for clicking and undetected drives.
What not to do
- Don't run free "repair" or "recovery" programs over and over on a failing drive.
- Don't run CHKDSK on a drive you suspect is failing — it writes changes to the drive and can make recovery harder.
- Don't open the drive. Opening a hard drive outside a clean room ruins it.
- Don't keep using it "until it dies." That's when recovery gets expensive.
Frequently asked questions
What is the first sign of a failing hard drive?
Usually slowness — slow startups, freezes and files that take longer to open. It's also the sign people ignore most. Have the drive tested before it gets worse.
Can a slow computer really be a bad hard drive?
Yes. In our shop it's the most common cause. A drive that's struggling to read makes the whole computer wait.
Do SSDs fail too?
Yes. They don't click, but they can slow down, throw errors, go read-only or disappear suddenly. The same advice applies: back up and get it tested.
How much does it cost to test a drive?
Nothing — drive testing is complimentary in our shop.
Can you get my files off a failing drive?
Often, yes, especially if you bring it in before it stops working completely. A backup of a failing hard drive starts at $150.
Computer getting slow or making noises? Bring it to 3512 Travis Street in Midtown for a free drive test — no appointment needed for in-shop visits — or call (713) 472-4357. Pickup, diagnosis and return delivery inside Beltway 8 is $99.
