Hi all recently bought three WD drives from OcUK a 2tb a 500gb and the 250gb the last one is a problem. Performance is way down on what it should be latest version of hdtune reports access time as being over 110ms and whilst looking i noticed AAM is set to the lowest of 128. Are there any utilities i can use to enable AAM and set it to performance or is this normal which i find hard to believe.
Other two drives are great no complaints on them but as the 250 is the main boot drive such poor performance is not good enough. Thanks for any help always appreciated
.
Ok been doing some testing just to ease my mind hdtune finds no physical problem with the platter error scan came back totally clean and the western digital lifeguard program also found no problems after extended test. Looking at the hdtune info screen the box for aam is not ticked which normally means it isn't supported but that cannot be right it is ticked on my 500gb drive so surely the 250 should have it also ?.
After doing some research elsewhere some people have used a program called hddscan to enable aam on some western digital drives but i havn't heard of the program before and am wary of using it hopefully some of you on here are more familiar with it. If the program is fine is it ok to enable aam if the drive is not reporting support for it. Sorry if i am asking noob questions but hard drives are not something i have put much time into in the past they have always just gone in and worked or had a problem that was easily identified and sorted.
