Just got a new SATA drive, if you have your primary drive as an IDE and install a new SATA drive, it won’t show up instantly when you go to My Computer. That is because the drive is not formatted yet. To fix this you need to format the drive and assign a label. Here are the simple steps.

After the device has been detected and reported ready for use.
Go to Start > Control Panel > Administrative Tools > Computer Management

Next select Disk Management under Storage. Your new sata drive should be detected. Right click on the drive and choose Format, follow the wizard steps and give the drive a label.

That’s it. Once done your new drive should show in the My Computer and ready to use.
