Hi , I have a problem with my Hitachi

SMART

Yellow 199 UltraDMA CRC Error Count 198 198 00000000-0003 000

It's defect ? Or I can use regulary

In my experience, that raw count of 3 is not high (unless the drive has been used for only a short period of time), and it is almost never a drive problem.

Many "guesses" are possible about what you could do. Depending on how long you have been using that drive, with that SATA cable, attached to that motherboard SATA port, you could either ignore this or try to troubleshoot it further. The problem you have for troubleshooting, is that the count is so low, it might be difficult for you to know if you have made any improvement. You need to decide if you want to do that PC troubleshooting.
