Hi, I see a number of people have had a similar problem but have tried all the solutions n nothing has worked.. Bought a new maotherboard and processor.. Installed windows xp sp2. USB pen drive gets detected but my USB IDE HDD 160 GB doe not.. Does not get detected at BIOS and windows hangs durng loading if it is connected. If i connected it after Windows load , icon for removable hardware come in the system tray and Device is seen in "device managment" but its hangs and you cant access anything. Do not see it in Computer management if I open the window and then connect the HDD. Cant open Computer management after connecting...Window will open only after I remove the HDD. Could it be a problem with IDE number. The new mother-borad has 1 internal IDE connector to which i have connected my old internal hard disk and DVD rom. Both get detected at boot up. Please help!
