ég er núna með 1 maxtor disk sem ég héf átt siðan i nóvember mjög gódur en fyrsti minn var wd hann hefur ekkert crasssasd neitt en hann er 112 gb en hann er með stæla núna og segjist vera með 111 gb

á þetta ekki að vera: "hann er 112 db en hann er með stæla núna og segjist vera 111 db"

Hef mjög góða reynslu af WD, SEAGATE og SAMSUNG. Hinsvegar hafa 3 IBM diskar gefið upp öndina hjá mér. Mæli ekki með IBM né HITACHI.
