You need to disable any pending operations via "HDD ID Edit" option in utility.

Other option is to set "power off/on" on error because (i believe) pending defects cause HDD to loose ready.

I got it 'OFF' and again turn it 'ON' but when i want to do any operation (for example view sub directory of partitions) the error "Error - Set UDMA = UDMA66" occurred and DWF and ABR register lights red.

OK then you need to remove all pending related options within utility. This should help.

Ok, But How can I work with utility to fix this problem?
I have another one of this model of HDD(STM3500320AS) that knocking sound and program can't recognize it, you know how can i Recover it? or some other HDD that knoking sound?

For knocking HDD you need to first diagnose it properley.

For pending option, I already stated it is under "HDD ID" options within utility.
