Storage?
The system recognizes a 120GB as 111GB, which is acceptable. Your 1TB WD Blue drive isn't appearing in Windows? Is the 1TB HDD recognized by the motherboard's UEFI BIOS? If yes, it might need reformatting using Windows Disk Manager. If not, inspect the connections to both the HDD and motherboard (and consider the possibility of a faulty drive).
The storage size changed unexpectedly from 120GB to 111GB possibly due to a system update or file system adjustment. Your UEFI BIOS shows your 1TB drive recognized, which is correct. To reformat the drive in Windows Disk Manager, open Disk Management, select the drive, click Format, choose a new format, and confirm.
The "120gb" SSD actually holds about 111GB due to how companies measure gigabytes—using 1,000 bytes per kilobyte instead of the standard 1,024. Your drive is likely storing around 120 trillion bytes.
Navigate to your partition manager in Windows and click on your HDD.
