If you view its raw value in hexadecimal, it appears to be reporting 22 (= 0x16) timeouts. This suggests that each unit of health corresponds to about 41 sectors (= 2639 / 64).Īttribute BC reports the number of Command Timeouts.

In other words, your drive has 2639 bad sectors which have been replaced with spares, and the 'health' of this attribute has dropped from 100 to 36. Think of the normalised values as health scores and the raw values as actual data. Tomorrow this value may fall to 35, in which case either your BIOS or Windows may register a SMART failure. Notice that the Reallocated Sector Count attribute is sitting right on the threshold (36). So why could it still be giving me the Windows HD Error and failing the SeaTools Short DST?Ī SMART attribute will be reported as 'OK' until such time as its current value falls below the threshold. There seems to be no problems at all according to HDTune. The Benchmark Test brought back the following: The Error Test brought back the following: (C7) Ultra DMA CRC Error Count 200 200 0 0 Ok (C6) Offline Uncorrectable 100 100 0 0 Ok (C5) Current Pending Sector 100 100 0 0 Ok

(05) Reallocated Sector Count 36 36 36 2639 Ok As a precaution, I have ordered an external hard-drive to back up my data on. My computer is running fine and I haven't suffered any data loss. I then decided to run one final chkdsk which again returned no problems. I then ran the Read/Write/Read Test which is designed to discover errors and fix them. I ran the Read Test and it discovered no problems.

I did a little bit of research and used a tool called HDAT2 for DOS.

I then proceeded to run SeaTools for DOS and it performed the Long Test with no problems but then failed right at the end when it tried to run the Short Test.
