Windows 8.1 działa bardzo wolno, wina dysku?

Witam.
Od jakiegoś czasu mam problem z systemem windows 8.1 na laptopie.
Wszystko chodzi bardzo wolno. Pliki otwierają się bardzo długo, np na uruchomienie FF muszę czekać kilka minut. Przeskanowałem system programem antywirusowym i nic nie wykrył. Wymontowałem dysk podłączyłem pod 2-gi komputer i przeprowadziłem diagnostykę.

Czy ktoś może ocenić kondycję tego dysku ?

Dysk remapował sektor, oraz w kolejce mogą czekać następne. Raczej na system się nie nadaje, może być na mniej istotne dane, jako dysk zewnętrzny. Po skopiowaniu danych i systemu należy wykonać zerowanie(MHDD, HDAT2, Vivard - pod DOS, Victoria, DMDE - winPE)
