A515-54 Incorrect NVME Drive Size? Replaced 512GB NVME but now showing only 475GB.

I replaced the 512GB NVME drive in my A515-54-5649 laptop with a 4TB Crucial CT4000P3PSSD8. This drive was listed as compatible on the Crucial web site. I cloned the original drive to this new 4TB drive, then swapped out the drive. It booted right up, and everything seemed to be working well.

Unfortunately, Windows is only showing this drive having 475GB. I checked disc manager and no unallocated space is available on the drive.

I tried updating the BIOS from 1.11 to the latest 1.24. No change.

How do I get access to the full 4TB of space on the NVME drive?

    The Crucial CT4000P3PSSD8 M.2 SSD should work, as the P3 is a PCIe3x4 and the most suitable for your laptops PCIe3x2 interface with slight performance reduction to what the PCIe3x4 can have and for such a large capacity drive for your laptop, but even the Crucial P5 PCIe4x4 drives will work as these drives are all backward compatible, but the performance of the drive may be limited by your laptops PCIe 3.0 x2 interface of course. The below specs are the Acer Aspire A515-54 Storage Subsystem specs, and the biggest capacity drive recommended for this laptop is the SATA III 2TB, so the 4TB should work within windows OS if its GUID (GPT) formatted.

    Try to reinstall your Aspire A515-54 IRST (Intel® Rapid Storage Technology) Driver Version 17.8.0.1065 on your laptop and see if that makes the OS recognize the 4TB M.2 SSD drive. If that doesn't work, then try to do a Clean Install of Windows and see if the Win-11 installation recognizes the 4TB M.2 SSD after you installed the IRST driver at the installation section of "Where do you want to install Windows > Load driver and you install the IRST driver to recognize the M.2 SSD boot drive, try all that and if all these steps don't work, then the 4TB M.2 SSD is not compatible with your Aspire laptop. Good luck and let us know how it worked out, hope this helps you out.

    Have the same laptop from 2019. The 4TB SSD (suggested by Crucial) is Gen 4x4 while the laptop slot is PCIe NVMe Gen3x2 only, furthermore I have not seen a 4TB NVMe SSD in this model, up to 1TB has been tested by Benchmark, IMO 2 TB NVME like the Samsung 970 EVO is also supported. https://www.userbenchmark.com/System/Acer-Aspire-A515-54G/144464

    Will try the suggestions… Ironically, if I open diskpart from a command line, it shows the total available space around 3.7 TB, which sounds about right. But I can't access the unallocated space there either.

    The question is do you have the 8th Gen i7 8565U or 10th Gen 10510U CPU? If you have the 2020 CPU it will support PCIe Gen. 3 1x4, 2x2, 1x2+2x1 and 4x1 but not Gen. 4x4 like the Crucial SSD. Also don't think 4TB is supported. See if you can change the 4TB crucial for a Samsung 970 2TB SSD.

    I finally figured it out!

    1. Open Windows disk manager and "shrink" the active C: partition. This forces Windows to recalculate the drive space which then shows the unallocated 3.7TB space at the end of the drive. Unfortunately, this left a 1GB recovery partition between two sections of unallocated space.
    2. Install Aomie Partition Assistant and "move" the recovery partition to the end of the drive.
    3. Restart the computer then use Windows disk manager to extend the active C: partition to fill the available space.

    I now have about 3.6TB on my active C: drive. Problem Solved!

    It's great that you've upgraded your laptop's NVMe drive, but it seems like there might be a limitation preventing the system from recognizing the full 4TB capacity. Here are some steps you can take to address the issue:

    1. BIOS/UEFI Settings:
      • Enter your laptop's BIOS/UEFI settings (usually by pressing a key like F2 or Del during boot).
      • Look for any settings related to drive recognition or storage configuration.
      • Ensure that the NVMe drive is recognized correctly and that there are no size limitations mentioned.
    2. UEFI vs. Legacy Boot:
      • Check if your system is set to boot in UEFI mode. Some older systems or configurations might not fully support UEFI, leading to capacity limitations.
      • If your system is currently set to Legacy Boot, consider changing it to UEFI and see if that resolves the issue.
    3. UEFI Firmware Update:
      • Even though you've updated the BIOS, there might be firmware updates specifically for the NVMe controller or storage-related components.
      • Check the official Acer support website for your laptop model and see if there are any specific firmware updates for the storage components.
    4. Driver Update:
      • Ensure that your NVMe driver is up to date. Visit the Crucial website or the device manager in Windows to check for the latest driver updates for your specific NVMe drive.
    5. Partitioning and Formatting:
      • If your NVMe drive was not fully recognized during the cloning process, there might be unallocated space that needs to be partitioned and formatted.
      • Use the Disk Management tool in Windows to check the status of the drive and create a new partition if necessary.
    6. Contact Crucial Support:
      • Reach out to Crucial's customer support for assistance. They may provide specific guidance based on the drive model and any known compatibility issues.

    It's important to note that while a 4TB NVMe drive should theoretically be supported, some older systems or BIOS versions might have limitations. If the issue persists after trying these steps, contacting Acer support for further assistance would be advisable.

    I hope this helps, and best of luck with resolving the capacity issue on your NVMe drive!

    I am getting around 3.6TB of usable space now which is right on par for a formatted 4TB drive. A couple of small partitions like the recovery partition take up a little space, but not much.
