A technician installed a new SSD in a computer that needed additional storage. The technician properly formatted and partitioned the drive. The BIOS recognizes the drive, but the drive does not appear

Replacing the drive is premature, as the BIOS recognizes it, indicating the drive itself is likely functional.

While assigning a drive letter is necessary, the disk must first be initialized before a drive letter can be assigned and the volume becomes visible.

Checking Device Manager would confirm the OS sees the drive hardware, but it wouldn't resolve the issue of the drive not being accessible as a storage volume in My Computer without further action in Disk Management.

Even after what appears to be formatting and partitioning, a new disk must be initialized in Disk Management before it can be assigned a drive letter and appear in File Explorer (My Computer). Initialization prepares the disk for use by creating a master boot record (MBR) or GUID partition table (GPT).
