Frequently Asked Questions

When the BIOS storage page does not list the SSD, no Windows tool can read it either. Recovery software needs the drive to appear as a device before it can scan anything, so the first task is to make the drive visible again, not to reinstall Windows.

What Not Detected in BIOS Tells You

A missing entry at the firmware level points to the connection, the power, the slot, or the drive controller. It rules out a Windows driver problem, because Windows has not seen the hardware yet. That changes the order of the diagnosis.

An SSD that appears in the BIOS but not in Windows is a different case: the drive is alive, and the problem is the storage driver, the partition table, or the file system. Recovery software can usually work on that drive once Windows assigns it a device entry.

Intermittent detection is a warning sign. A drive that appears after several cold starts, or disappears under load, is often a loose connection, a failing controller, or a firmware issue. Stop using it for important work and copy the data as soon as it appears.

Try Another Slot and Another PC

Power off, unplug the battery where possible, and reseat the M.2 drive. Clean the contacts with a dry, lint-free cloth, then install it in a different M.2 slot if the board has one. For a 2.5-inch SATA SSD, replace both the data cable and the power cable before blaming the drive.

Check the firmware storage settings. On Intel boards, VMD or Intel Rapid Storage Technology can hide a drive from the operating system while still showing it in a RAID menu. AHCI and standard NVMe modes are the usual choices for a single drive.

Connect the drive to another PC through a USB NVMe or SATA enclosure. If it appears there, the original slot or board is the problem; if it does not appear anywhere, the drive itself is likely failing.

Recover Through USB Before Repair

Once the drive appears on another PC, copy the files before you update firmware, run a repair, or reformat it. A firmware update can reset controller state and, in a failing drive, can make the device disappear for good.

Use a powered enclosure for large drives and connect it directly to the PC, not through a hub. If the drive disconnects during the copy, stop and reconnect it; repeated dropouts can corrupt the file system further.

Do not open the drive or attempt a chip-level repair at home. An SSD has no serviceable parts inside, and opening it can destroy the NAND mapping that a professional lab needs.

Scan the Drive with Qiling

Qiling Deep Data Recovery can scan the SSD once another PC or a USB enclosure makes it visible. It reads the disk and writes the recovered files to a different destination, so the failing drive is not used for output.

Step 1. Choose the Scan Mode

Use the deep scan when the drive is recognized but no volume appears. If the SSD was formatted by mistake, use the format scan mode instead.

Step 2. Select the SSD

Pick the physical disk in the enclosure and confirm its capacity and model. A drive that drops out during the scan may need to be reconnected; do not restart the whole computer if only the USB device failed.

Step 3. Recover to Another Disk

Preview the results and save them to the host PC or a second external drive. Keep the recovered copy until you have decided whether to replace or repair the original SSD.

Frequently Asked Questions

Can software recover a drive the BIOS cannot see?

No. The drive must be enumerated by the hardware before any software can scan it.

Why does the SSD appear in BIOS but not in Windows?

The drive is alive, but Windows lacks the right driver or cannot read the partition table. Recovery software can often help in that state.

Is a USB enclosure safe for recovery?

Yes for a stable drive. Use a powered enclosure and a direct port, and stop if the drive disconnects repeatedly.

Should I update the SSD firmware first?

Not before copying the data. A firmware update on a failing drive can make it disappear permanently.
