S.M.A.R.T. shows strange errors

I've bought new 240G Neutron GTX (firmware M311). When I run smartctl it shows clean values for attributes but it also shows the last 5 errors. According to their numbers and time of their appearance they appear every time when BIOS tries to initialize drive.

My motherboard is Gigabyte AMD RS690 (SB600) based. Can anybody explain these errors and what should to do? Here the errors, they are always the same:

Error 175 occurred at disk power-on lifetime: 54 hours (2 days + 6 hours)

When the command that caused the error occurred, the device was in an unknown state.

After command completion occurred, registers were:

ER ST SC SN CL CH DH

-- -- -- -- -- -- --

01 50 01 01 00 00 00

Commands leading to the command that caused the error were:
