A yellow Caution box is the point where you stop guessing and make a backup. It may flag one weak sector count, a hot drive or another SMART threshold. CrystalDiskInfo Caution gives you a lead to investigate, and the highlighted attribute tells you which lead to follow.
Quick Answer
Copy important files first, then read the yellow SMART row and save a screenshot. A stable warning may give you time to monitor or replace the drive; a rising error count, freezes or disconnects calls for retirement. Evetech priced the 1TB Hiksemi T100 Pocket portable SSD at R1,299 in its July 2026 snapshot, which gives you one priced option for moving data off a suspect drive.
🟡 Find the attribute behind the colour
CrystalDiskInfo highlights the row that crossed its threshold. On a SATA drive, that may involve reallocated or pending sectors. NVMe uses a different health log, with available spare, percentage used and media errors among the useful fields.
Select the correct disk at the top. Many PCs have a Windows SSD, a game drive and a USB disk connected at once. Write down the model and serial suffix so you do not back up the wrong one.
Use Evetech's SSD category later to match the physical format. The warning step belongs to the drive on your screen.
📈 Watch whether the raw value changes
Save the report, restart the PC and check again after ordinary use. A raw error count that rises gives you a clear reason to stop trusting the drive. Temperature that falls after you clear dust or fit a heatsink points to cooling.
Do not run repeated full benchmarks to see whether the warning disappears. A weak drive needs fewer writes while you rescue data. Use the SSD maker's diagnostic tool for a second reading if it supports the model.
🧳 Decide what the drive may still do
Keep it out of any role where it holds the only copy. A Caution drive may serve long enough to complete a backup, but Windows freezes or disappearing volumes can interrupt a clone. Copy the smallest irreplaceable folders first.
Check proof of purchase and the maker's health-report requirements before an assessment. Evetech's best-selling SSD list can help with replacement capacity once the data is safe.
Frequently Asked Questions
What triggers a Caution status in CrystalDiskInfo?
One or more SMART attributes crossed the utility's warning threshold. The yellow row identifies the trigger.
Does Caution mean the SSD is about to fail?
It cannot give you a failure date. Treat the warning as a reason to back up and inspect the trend.
Should you keep using a drive marked Caution?
Use it only after important data exists elsewhere. Rising errors or disconnects justify prompt replacement.
Can a Caution status turn back to Good?
A temperature warning may clear when cooling improves. Permanent media or wear counters may remain recorded.
How is Caution different from Bad?
Caution marks a crossed warning threshold. Bad signals a more serious health condition that needs immediate data rescue.
Moving files away from a yellow health warning?
Check Evetech's SSD range for the interface and capacity your PC accepts, then verify the backup before retiring the old drive.
