Drives rarely fail without warning. They fail with a window — days or weeks where the signs are there and the data is still readable. Acting inside that window costs you an afternoon. Missing it costs considerably more.
Signs you can hear and see
- Clicking, ticking or grinding. On a traditional spinning drive this is mechanical and it is serious. Turn the machine off. Every extra minute of running risks the read head damaging the surface holding your files.
- Files that vanish or will not open, or folders that appear empty and then do not.
- Very slow copying, especially when it stalls at a particular file and then resumes.
- Freezes where the whole machine stops for thirty seconds and comes back.
- Crashes that get more frequent with no other explanation.
- It sometimes does not appear at boot and then does after a restart. That is not intermittent luck; that is a drive going.
SSDs fail differently
Solid-state drives make no noise, so the audible warning does not exist. They tend to go from working to unreadable more abruptly, and often turn read-only first — you can open files but nothing saves. If an SSD suddenly refuses to save anything, copy your data off immediately. That is frequently the only warning you get.
What to do, in order
- Copy the irreplaceable things first. Photos, documents, tax records. Not a disk image, not a clone — just the files that cannot be recreated, to another drive or a cloud service.
- Do not run repair tools yet. chkdsk and similar write to the drive, and writing to a failing drive can finish what it started. Copy first, repair later.
- Do not keep using it once the important files are safe.
- If it is already clicking, stop. Powering it on repeatedly makes professional recovery harder and more expensive.
Being honest about recovery
If the drive is dead and the data matters, cleanroom recovery is real and it is expensive — often four figures. That is the argument for backups: they are the cheapest insurance in computing, and they only work if you set them up before you need them.
