I have tried figuring this out and searching for an answer but nothing is working. I just installed a second hard drive as 'slave' on my primary IDE cable. When I try to burn at 8x on my dvd burner(master on secondary IDE) using data from the newly installed hard drive I get a 'power calibration error'. I have changed IDE cords, tested and made sure that I can burn fine from my 'master' hard drive at 8x, I do not know what else to do . I have wasted many blanks trying to troubleshoot this problem, if anyone has any clue to what is wrong I would greatly appreciate a response. THANKS!
