When I plug the microphone into the jack of front panel, I cannot find the "Front Mic" under "Mixer" of VIA "HD ADeck" for volume adjusting. What should I do?
VIA has removed the item "Front Mic" from the newer versions of "VIA HD Audio Driver". Now the item "Microphone" in below screenshot is for the "Rear Mic" as well as the "Front Mic". When you plug the microphone into the jack of front panel, you can adjust it's volume by the option "Microphone". It is the same when you use "rear microphone".
If you plug the microphones into the jacks of front & back panel at the same time, the item "Microphone" will only work for the "Front Mic" under this situation.
Can this model support 3TB HDD?
Yes, this model with UEFI BIOS can support 3TB HDD. UEFI BIOS uses a GUID Partition Table (GPT) that can define hard drive larger than 2.2TB. As a bootable disk over 2.2TB partition, operation system like Windows 7 64-bit is required to support. For data only over 2.2TB, OS with GUID Partition Table (GPT) support is required.
