От 8-9 месеца имам едно лаптопче
Acer Aspire 4810TZ Моят модел дойде с Windows 7 Home edition, 4GB ram и 500GB диск. Естествено веднага след като го взех преоразмерих партишъните качих си Windows 7 Umtimate след което си качих и Kubuntu lucid на който съм работил през 98% от времето. Преди около седмица ми се наложи да си пусна windows-а при което той почна да пищи че диска имал проблеми и трябвало да съм започнел незабавна процедура по backup и перформънса му беше ужасен. Отварянето на браузър ми костваше по 3-4 минути. В същото време Kubuntu-то си ми работи на пушка, затова реших че проблема е в OS-а и го рестартирах. След рестарта windows-а почна да си прави чекове на C-то като откриваше една камара грешки, които уж отстраняваше. След като се рестартира чека почваше наново. Повторих тази процедура 3-4 пъти след което ми писна и му казах на Windows-а да се стартира без да прави проверка. Производителността беше кошмар, като и на всичкото отгоре ми се бяха изтрили половината файлове на firefox и разни други приложения. Заради всички тези проблеми реших че проблема е в OS-а на Гейтс затова му
преформатирах партишъните с ext4 и го разкарах (ако някой иска да види как съм го направил може да кликне на линка).
Качих си на Kubuntu-то един Vmware workstation с помощта на който на стария С дял си инсталирах една виртуална машина с Windows 7. Инсталацията мина нормално за около 30-40 минути. Обаче когато почнах да си качвам приложения във виртуалния windows load-а на компютъра ми варираше между 15 и 20, vware-а взе да реве че не може да достъпва някакъв файл и dmesg почна да бълва ето такива съобщения:

Въпроса ми е това хардуерен проблем ли е или е някаква моя грешна конфигурация? В момента като си работя само на Kubuntu-то нямам никакви други проблеми.
Предварително благодаря!
