New SSD Not Recognized or Uninitialized: Partition & Format Guide

💡 Why isn't my new SSD showing up in 'This PC'?

Factory-new SSDs ship in an Uninitialized raw state without a partition table (GPT/MBR) or drive letter. File Explorer only displays mounted volumes with assigned letters. Open [Disk Management] to initialize and create a simple volume. If the drive is missing from Disk Management entirely, jump to Step 5 for BIOS and hardware checks.

Open Windows Disk Management & Initialize Disk (Select GPT)

On Windows 10 or Windows 11, launch Disk Management using the steps below:

Right-click the Windows Start button (or press Win + X) and select [Disk Management].
A prompt to Initialize Disk will appear automatically. (If not, locate the drive labeled Unknown / Not Initialized in the bottom pane, right-click its left label box, and select [Initialize Disk]).
Select GPT (GUID Partition Table) as the partition style and click [OK].

Create a New Simple Volume & Format (NTFS / exFAT)

Once initialized, the disk status changes to 'Online' with black Unallocated space on the right. Next, create a file system and drive letter:

Right-click the [Unallocated] space, select [New Simple Volume], and click Next.
Specify Volume Size: Leave at the maximum default size (a single full-drive partition is recommended for optimal controller garbage collection) and click Next.
Assign Drive Letter: Choose an available drive letter (e.g., D: or E:) and click Next.
Format Partition: Select NTFS (best for Windows OS/gaming drives) or exFAT (for Windows + macOS cross-platform use), keep Allocation Unit Size at Default, check Perform a quick format, and click Finish.

Partition Style (GPT vs MBR) & File System Selection

Choose the appropriate partition table and file system based on your FuEpoch SSD capacity and platform:

Setting	Recommended Option	Use Case & Engineering Notes
Partition Style	GPT (GUID Partition Table)	Supports capacities above 2TB (e.g., 4TB / 8TB / 30.72TB enterprise drives) and native UEFI boot. Always choose GPT for modern SSDs.
Legacy Partition	MBR (Master Boot Record)	With 512-byte logical sectors, MBR addresses about 2 TiB (2.20 TB). Use GPT for larger drives.
Windows File System	NTFS	Supports journaling, permissions, large files, and DirectStorage. Ideal for Apex 9000/7000 Pro and Orbit series.
Cross-Platform / PSSD	exFAT	No 4GB file-size limit; native read/write on both Windows and macOS. Recommended for FX-GO Portable PSSDs.

macOS & Linux Enterprise Server Initialization Commands

If deploying FuEpoch storage on macOS workstations or Linux servers, use the native system utilities:

macOS (Disk Utility): Open Disk Utility, click View → Show All Devices in the top-left corner, select the top-level physical SSD, click [Erase], set Scheme to GUID Partition Map, and choose APFS (Mac-only) or ExFAT (cross-platform).
Linux Server (Vault U.2/U.3 / E1.S / NVMe): Identify the block device via nvme list or lsblk (e.g., /dev/nvme1n1), then create a 4K-aligned GPT partition and format as XFS or ext4:

Use these commands only on a verified empty drive. Replace the example device path with the correct device. Creating a partition table or formatting can destroy existing data.

            # 1. List detected NVMe devices

            sudo nvme list

            # 2. Create a GPT partition table and a 4K-aligned primary partition spanning the drive

            sudo parted -a optimal /dev/nvme1n1 mklabel gpt mkpart primary 0% 100%

            # 3. Format as XFS for enterprise database and AI workloads

            sudo mkfs.xfs /dev/nvme1n1p1

Advanced Troubleshooting: Drive Missing from Disk Management?

If the SSD does not appear in Disk Management at all, verify the physical connection and motherboard BIOS settings:

Reseat Physical Connector: Power off the system, unplug AC power, remove and re-insert the M.2 or U.2 SSD firmly into the slot, and secure the retention screw without over-tightening.
Verify Slot Protocol (NVMe vs SATA): FuEpoch Apex, Orbit, and Vault NVMe SSDs use the PCIe NVMe protocol (M-Key). Legacy M.2 slots wired exclusively for SATA will not detect NVMe drives.
Check BIOS Lane Sharing & Storage Mode: Enter BIOS (Del or F2 at boot) to ensure the M.2 port is enabled and not sharing disabled lanes. If Intel VMD or RAID is enabled, use the storage driver recommended by your system manufacturer. Changing storage controller mode can prevent an existing OS from booting.
Check Windows Storage Spaces: Search for Manage Storage Spaces in Windows to verify the new drive was not automatically claimed by an unconfigured storage pool.

⚠️ Data Safety Warning: Initializing, creating partitions, or formatting erases existing partition tables. If your drive contains prior data rather than being brand-new, do not initialize it—contact FuEpoch Support first.
