2.61 mela problem s Intel Ultra ATA Storage Driver

Some customers have reported that version 2.61 of HD Tach* (utility created by TCD Labs*, Inc.) reports high 'CPU utilization' when the Intel® Ultra ATA Storage Driver is installed. After further investigation of HD Tach version 2.61, the producers of HD Tach indicated to Intel that the tool is targeted as a disk and driver tuning tool and not necessarily as a benchmark for grading the real-life 'CPU utilization' of a storage driver. Listed below is the technical explanation of why the 'CPU utilization' is reported as higher in HD Tach version 2.61 when the Intel Ultra ATA Storage Driver is installed.

Dost lidem, i tem co maj SATA disky hazi HDtach 2.7 dost vysoke CPU utilization(od 40-60procent) na ruznych sestavach.
