SMART Data Interpreter (CrystalDiskInfo)
Paste a CrystalDiskInfo report and get the same verdict, from the same five attributes.
What you paste
Parsed in your browser — never uploadedHow this reads your output
CrystalDiskInfo writes its report through its own Edit menu as an aligned text block. Paste the whole thing and the attribute table is read into the same shape the smartctl tool uses, then judged by the same rules — which is deliberate, because a Windows user and a Linux user asking about the same disk should not get different answers. The one format-specific trap is handled properly: the ID column is hexadecimal, so attribute B1 is decimal 177 (wear levelling) rather than 181, and a parser that reads it as decimal quietly labels every attribute above nine as the wrong thing.
What the results mean
- Health Status
- CrystalDiskInfo's own summary, which turns from Good to Caution when a vendor threshold is crossed. Useful, and later than the attributes it is derived from.
- Wear levelling count (B1)
- On an SSD, the percentage of rated write endurance remaining. Reaching zero means the warranty endurance is spent, not that the drive stops.
- Reallocated sectors (05)
- Sectors remapped after failing. Any non-zero value on a modern drive is worth watching; a growing count is the clearest failure signal there is.
- CRC error count (C7)
- Interface errors between drive and controller — the cable, in almost every case. The counter never resets.
Common problems and fixes
- No attribute table was found
- Use CrystalDiskInfo's Edit menu to copy or save the full report. A screenshot or a partial selection will not contain the table.
- It says Caution but everything looks fine
- Look at which attribute crossed its threshold. On an SSD it is usually wear levelling, which is expected ageing rather than a fault, and on a hard drive it is usually reallocated sectors, which is not.
- My SSD shows 95% health after two years
- That is normal. SSD wear is measured against rated write endurance, and most drives are retired for other reasons long before they reach the limit.
Frequently asked questions
What does the CrystalDiskInfo health percentage mean?
On an SSD it is usually derived from the wear-levelling attribute — the proportion of rated write endurance remaining. On a hard drive it reflects how close the worst attribute is to its vendor threshold. It is a useful summary and a late one: the individual attributes show trouble well before the percentage moves.
Is "Caution" a reason to replace the drive?
It depends entirely on which attribute triggered it. Reallocated or pending sectors on a hard drive mean back up now and plan a replacement. Wear levelling on an SSD past its rated endurance means the warranty is spent, not that the drive is about to stop — plenty run for years past it. The verdict above says which case you are in.
Is my report uploaded?
No. It is parsed in your browser, and the drive serial number is excluded from anything this tool exports.
