SSD issue

[ultraman7k]

repost from the storage subforum...

so my friend bought a new SSD, kingston 128 gb gen II and he would like to get it to work, except when he installs it, it will not work concurrently with his SATA WD 500gb hard drive which still has windows 7 on it, as the SATA drive is not showing up when he tries to install. Isn't it weird that it won't recognize...? Although the drive does show when the SSD is removed...they just won't work together!

help would be greatly appreciated.
