I've recently bought the Asus ZENBOOK UX32VD and had to install a Samsung 7 series for a customer.

Both laptops comes default with an express cache or iSSD. I am a firm believer of reinstalling a laptop from scratch to remove all the bloat ware. One of the mistakes that I've made is to format the express cache or iSSD. And so the cache wouldn't work.

This is how to correct that problem:

Just create a HFS partition on the express cache or iSSD.

You can do this easily by pressing SHIFT+F10 in the windows 7 setup. Then you get a command prompt. Enter the following things:

diskpart

In diskpart enter the following things:

list disk

This will show you all your disks. Watch for the express cache size. Remember the disk number. Mostly this will be disk 0. Then do the following commands to create the right partition.

 

Select disk 0

create partition primary id=af
