Hey all, I recently bought a Hard Drive Modular Hard Drive Kit from Fujitsu. The description as advertised by the Manufacturer, "This modular Hard Drive Kit allows you to add a second hard drive to your computer using the modular bay. Use it as an additional storage option or backup drive. Before proceeding with assembly of the modular hard disk drive kit, you must first purchase an appropriate hard disk drive. Please Note: This kit can only be used with a Serial ATA (S-ATA) 2.5-inch drive with dimensions of: 100 mm x 70 mm x 9.5 mm (3.9" x 2.75" x 0.37"); it will not accommodate a Parallel ATA (P-ATA) drive." I installed a ADATA 256gb SSD Drive. It fit in perfectly. Started the laptop up, it was recognized in my BIOS, but not in Windows. Can't find it in device manager, disk management or anything. Installed the Driver from ADATA'S website as well. This is my first time adding hardware to a laptop. This laptop allows for a 2nd hard drive to be installed. It can be removed by simply pressing up on a tiny latch.
