My Secondary Hard Disk is detected somethimes and other time when i use normally my pc it disappear! And i have to reboot my pc to see it again.. other time i can't see even if i reboot the pc.. Two minutes ago i have open EasyBcd to change the boot configuration 'cause i've installed xp in this secondary hard disk and the drive is disappear... Indeed I can't use xp probably for this inconvenient... In the boot option when i boot my computer there's only windows 7...
And sorry for my bad english..
