You installed a new mSATA SSD into your HP 9470, but the system will not see it in BIOS or Windows. This page gives you the exact HP diagnostics steps and seating checks to find out if the issue is a setting, a loose connection, or a failed drive.
In short: The drive is likely not seated fully in the m.2 slot or the BIOS is set to a legacy SATA mode that ignores the new hardware. Restart into the HP BIOS, reset the boot settings, and ensure the SSD is locked down with the single screw. If it still does not appear, test a known-good drive to confirm whether the slot or the SSD is faulty.

The HP 9470 Uses a Specific mSATA Slot
The HP 9470 ProBook uses an mSATA connector for its solid-state storage. This is different from the common M.2 NVMe slots found in newer laptops. If you bought a generic M.2 SSD, it will not fit or work in this machine. If that sounds like your bench, read up on laptop not recognizing usb drives next.
The slot is a small, flat component that sits near the center of the motherboard, often held by a single screw and a bracket. It requires a specific keying that aligns with the physical notch on the drive.
Before you open the laptop, confirm the part number on your SSD. If it is labeled as a 2242 or 2280 M.2 drive, you have the wrong form factor for the 9470. You need a drive specifically labeled mSATA or NGFF mSATA.
- Check the bottom of the SSD for the mSATA label.
- Verify the keying matches the slot on the HP 9470.
- Do not attempt to force an M.2 drive into this slot.
Pro tip: Many users buy M.2 NVMe drives by mistake. The HP 9470 does not support the NVMe protocol in this slot.
The USB adapter in this kit allows you to test the mSATA drive externally if the internal slot is suspect.

BIOS Not Seeing the Drive? Check These Settings
Restart the HP 9470 and press F10 to enter the BIOS setup utility. This is the first place to look when a drive is not detected in Windows.
Navigate to the Advanced or Storage tab. Look for the mSATA slot. If the slot is listed but shows no drive, the connection is loose. If the slot is missing entirely, the board may be disabled or faulty.
Check the Boot section. Ensure that Legacy Support is enabled if you are cloning a drive, or set to UEFI if you are doing a fresh install. Some HP models hide non-native drives if the boot mode is set incorrectly. We cover ssd not detected in a guide of its own.
- Press F10 at startup to enter BIOS.
- Select the ‘Storage’ or ‘Advanced’ tab.
- Verify the mSATA slot is visible in the list.
- Save and exit by pressing F10 again.
Pro tip: If the slot is missing from the BIOS, do not force a new drive. It may indicate a motherboard failure.
Seating the mSATA Drive Correctly
A loose mSATA drive is the most common reason for ‘not detected’ errors. The connector is delicate and does not have the robust snap of a 2.5-inch SATA drive.
Insert the drive at a 30-degree angle until the gold fingers touch the socket. Then, press it down vertically and fasten the single screw at the far end. Do not overtighten; just hold it firm against the board.
If the drive is not seated, the pins may not make contact. A slight wiggle during insertion can bend the pins, so work slowly and look through the opening to align the key before pushing.
After seating, restart and enter BIOS immediately. If the drive appears, the previous installation was simply loose.
Is the SSD Actually Dead? Use External Testing
If the BIOS still does not see the drive, the SSD itself may be faulty. Test it outside the laptop to rule out a motherboard issue. Before you buy anything, it is worth looking at missing storage device.
Use a USB to mSATA adapter or a dedicated enclosure. Connect the drive to another computer. If Windows sees it, the drive is good and the HP slot is the problem. If it does not appear, the drive is likely dead.
You can also use a data recovery tool to check for partitions. If the drive shows up as unallocated but has no size listed, the controller may have failed.
- Connect the mSATA drive via USB to a different PC.
- Check Disk Management in Windows to see if it appears.
- If it is visible, the HP 9470 slot or solder is the failure point.
Why Other SATA SSDs Might Not Show Up
Users often confuse mSATA with standard 2.5-inch SATA SSDs. A standard SATA drive will not work in the m.2 slot on the HP 9470. It requires a specific adapter card to bridge the connection.
Some motherboards in older HP ProBooks support a 2.5-inch drive bay instead of m.2. Check your service manual to see which slot your specific 9470 revision uses. Not all 9470s have the m.2 option enabled in BIOS by default.
If you are trying to add a second drive, ensure the BIOS allows multi-drive booting. Some HP models require a specific firmware update to recognize non-primary storage devices.
Common Mistakes and Myths About mSATA Detection
Myth: A BIOS update will always fix detection. Fact: Firmware can change how the board talks to the drive, but it cannot fix a loose physical connection. Always check the screw first.
Myth: The drive needs a driver in Windows to be detected. Fact: The SATA controller is built into the chipset. Windows sees it as soon as the BIOS hands it off. No extra drivers are required for basic detection.
Myth: If it works in BIOS but not Windows, the drive is bad. Fact: This usually means the drive has no active partition table. You must initialize and format the drive before Windows will show it in File Explorer.
- Loose Screw: The #1 cause of intermittent detection.
- Wrong Drive Type: Buying M.2 instead of mSATA.
- No Partition: BIOS sees it, but Windows does not.
The bottom line
Start by reseating the mSATA drive and checking the BIOS under F10. If the slot is missing or the drive is not visible in a USB adapter, the SSD or the motherboard slot is faulty. For most users, the drive is simply not seated correctly or is the wrong physical form factor.

Frequently asked questions
How do I maintain an SSD in a laptop?
Modern SSDs do not need manual TRIM optimization as Windows handles it automatically. Just keep the drive cool and avoid letting it become 100% full. Regular updates to your BIOS and chipset drivers also help maintain compatibility and performance.
Should I get a 1 TB SSD for my HP 9470?
The HP 9470 has limited internal space. While a 1TB mSATA drive exists, they are less common and slower than modern M.2 NVMe drives. A 512GB to 1TB mSATA drive is a good upgrade, but check the specific part compatibility with your model number before buying.
Why does my laptop say 'referenced memory not detected'?
This error usually points to a RAM stick that is not seated properly or a faulty memory module. It is separate from the mSATA issue. To fix it, remove the RAM, clean the contacts with an eraser, and reseat it. If the error persists, test the RAM one stick at a time.
