Power down the PC, reseat the SSD, and check the SATA or power cable. For M.2 drives, make sure the screw is snug and the drive is fully inserted.
Enter BIOS and confirm the SSD appears there. If it does not appear in BIOS, the issue is usually hardware, slot compatibility, or cabling.
If the SSD shows in Disk Management but is unallocated, initialize it and create a volume. Only do this for a new drive or one you can erase.
Install the latest chipset and storage drivers from the motherboard or laptop manufacturer. Driver issues can hide a drive from Windows.
If possible, connect the drive to another system or port to see whether the drive or the original slot is the real problem.
M.2 SSDs are sensitive to physical pressure and static discharge. Always ground yourself by touching a metal surface before handling the drive. Insert the SSD at a 30-degree angle into the M.2 slot and press it down gently until the retention screw aligns. Do not overtighten the screw as it can crack the PCB. For 2.5-inch SATA SSDs, ensure the SATA data and power cables are fully seated and the drive is secured in its mounting bracket to prevent disconnection from vibration.
Motherboard manufacturers frequently release BIOS updates that improve NVMe compatibility, especially for newer SSD models. Visit your motherboard manufacturer's support page and check for BIOS updates. After updating the BIOS, also install the latest chipset drivers from the manufacturer's website. Outdated BIOS firmware is a common reason why a new SSD is not detected during installation, particularly on older motherboards that received NVMe support through later firmware patches.
SSDs have a limited lifespan determined by write endurance. Most manufacturers provide free monitoring tools that show drive health, temperature, and remaining lifespan. Download Samsung Magician, Crucial Storage Executive, WD Dashboard, or your SSD brand's utility. Check the drive health percentage and total bytes written every few months. If the health drops below 80%, back up your data immediately and plan for a replacement before unexpected drive failure occurs.
Some SSDs, particularly NVMe drives, are not detected when the BIOS is configured in Legacy/CSM mode instead of UEFI. Enter your BIOS setup during startup (usually by pressing Del or F2), navigate to the Boot section, and ensure CSM is disabled and Secure Boot is enabled if your OS supports it. Save changes and exit. If the drive was previously detected but disappeared after a BIOS update, check that the SATA or NVMe controller is set to the correct mode (AHCI for SATA SSDs).
If your motherboard has multiple M.2 slots, try the SSD in a different slot. Some M.2 slots share bandwidth with SATA ports or PCIe lanes, and using them simultaneously can disable the SSD. If the drive works in another slot, check your motherboard manual for lane-sharing limitations. For SATA SSDs, try a different SATA port and cable. A USB-to-SATA adapter can verify whether the drive itself is functional independent of your computer's internal controller.
Some SSD models require specific drivers to appear correctly in Windows or macOS. For NVMe drives, Microsoft provides a standard NVMe driver, but installing the manufacturer's driver can improve detection. On macOS, some third-party NVMe drives need NVMeFix.kext to prevent wake-from-sleep detection failures. Check the manufacturer's support page for firmware updates that may address compatibility issues with your specific motherboard chipset or operating system version.
Yes. Initializing and formatting erases all data on the drive, so only do this with a new drive or one you do not need data from.
The drive may need to be initialized in Disk Management, or it may need a partition and format before Windows can use it.
No. NVMe SSDs require an M.2 slot that supports PCIe NVMe, not just any M.2 slot.
Speed depends on the interface, PCIe generation, lane sharing, and whether the drive is throttling from heat.
Yes, a standard 2.5-inch SATA SSD can be placed in a USB 3.0 enclosure and used as an external drive. This is a useful way to recover data from an SSD that is not detected internally. The drive must be in good working condition and properly formatted. Note that TRIM support may not be available over USB, so long-term use as an external drive may result in reduced write performance over time compared to internal SATA connections.
NVMe SSDs generate significant heat during sustained read and write operations, especially PCIe Gen 4 and Gen 5 drives. If your SSD does not have a heatsink or is in a location with poor airflow, it may throttle its speed to prevent damage. Install the motherboard's included M.2 heatsink or purchase an aftermarket SSD heatsink. Monitor temperatures with your manufacturer's tool; sustained temperatures above 75 degrees Celsius indicate inadequate cooling.
M.2 SATA SSDs use the same SATA protocol as 2.5-inch drives but in the M.2 form factor, with maximum speeds around 550 MB/s. M.2 NVMe SSDs use the PCIe bus directly and offer speeds from 3,500 MB/s to over 10,000 MB/s depending on the PCIe generation. They look almost identical, but a motherboard's M.2 slot may support only one type. Check your motherboard manual to confirm whether the slot supports SATA, NVMe, or both before purchasing.
Try the same service on a different device or network. If it works elsewhere, the issue is local to your device or network. If it fails everywhere, the service itself may be down - check Downdetector or the service's official status page to confirm.
Yes. A full restart (not just closing the app) clears stale connections, frees memory, and resolves the majority of intermittent glitches. Try this before deeper troubleshooting steps.
Open the App Store (iPhone) or Google Play Store (Android) and search for the app - if an Update button appears, tap it. On desktop apps, look for an About or Check for Updates option in the menu. Outdated apps often break after server-side updates.
If clearing the cache, updating, and restarting have all failed, reinstall the app as a last resort. A clean reinstall removes corrupted data, settings, and permissions that the standard fix steps cannot reach. Your account and saved data are stored in the cloud, so you won't lose anything by reinstalling.
