My name is Zach and I have installed a 2.0TB hard drive into my Dell computer. Whenever I use the computer my hard drive works fine. Creating path letter for it and everything. It is healthy and everything. As soon as I restart my computer, the path letter I have chose for my 2.0TB drive is no longer there and I have to go under disk management again. I have Windows 7 32bit and the BIOS says everything is good to go. Besides restarting the computer, everything works like a charm
1) Is this a primary or secondary drive?
2) What is the model of your Dell PC? (If an older PC, it might not fully support 2TB drives and is causing an issue) A BIOS update might be a good option to try.
