HDD not recognized?

Well, sort of.



Ill explain



The PC originally had (still has) a WD4000AAJS HDD installed. I added a second HDD, a WD7500AAKS. Went into BIOS, made sure the original was set to boot 1st in boot priority & proceeded to boot.



the OS (Vista home premium 32-bit) loads perfectly, but when I went to format the drive (under Computer/My computer) its not there However, if I go look for it via Control Panel>Hardware & Sound>Device Manager. The new HDD is listed under Disk drives. I cant however format it to NTFS through this.



So, what now? I cant use this thing if its in FAT32 format.



Im hoping this may just be some newbish error on my part. Any help/suggestions are greatly appreciated. If any other info is needed to help get to the bottom of this, ask away.



Thx.

Control Panel-Administrative Tools-Computer Management-Click on Disk Management on lower left- In the lower right pane right click on the drive and partition and format. Or just click start and right click Computer and click Manage

Ill be making note of this, Thank you.
