My hard drive for Sata II does not seem to be working good. For a while now it will not boot properly, I changed boot sequence so that HDD booted first instead of DVD. xp logo appears for 1second then a screen flashes blue for less than 1second and it reboots after asking if you want to reboot normally or in safe mode every time it does this, yet after 2nd or 4th reboot it boots normally and everything is fine. I did notice when I installed the drive that the red cable for the hard drive was extremely loose, but I dont think that is the problem as I have got it fixed. mobo is e-Sata 2 Asrock, I just dont understand why some days it turns on fine and others its picky.
