    PC won't recognise 64 Gb SDXC card


    I bought 2 64Gb SDXC cards back in September and my PC running Windows 10 PRO recognised these cards and I was able to write to them. I bought another one a few days ago, but the PC will not recognise the card and when I tried the 2 cards I already had again, it wouldn't recognise them either. The PC will read an 8Gb Kingston 133X card and lots of other small cards without problems. My laptop will read these SDXC cards without problems. It is running Windows 10 Home, which is also Version 1709, build 16299.98 & both laptop & PC are running what appears to be the same driver - a generic Microsoft driver dated 21/9/2006 version 10.0.16299.15 Also my digital camera and my Panasonic video camera will recognise the cards. I've tried updating the PC driver, but Windows insists that the driver installed is the best available. The PC has just done a big Windows update but that hasn't cured the problem. I'm baffled - has anybody got any suggestions?I don't really want to roll back to any old version of Windows, especially as I've no idea when the problem started. The card reader is built in to the PC and came bundled with the machine (about 7 years old) and appears to be some generic make as there is no manufacturer's name visible. I've ordered a plug-in card reader to see if that will work, but I'm not hopeful.

    Poor contacts in the SD Card Reader/SD Card are a problem.
    Cleaning the contacts on the SD Card reader works for my Laptop, 4 years old. I do that by carefully using a small sliver of suitable cardboard, slightly damp, slightly rough but does not shed bits.

    Also similarly deal with the SD Card contacts as well.

    Air duster cans don't work other than to shift some loose dust out.
    It's the same driver on mine.

    All the SDXC cards I've seen/have come with an adapter for the SD slot, could be an issue there. I carry a USB adapter that accepts both the SD and SDXC cards, handy for transferring pictures from a cellphone, cameras, etc. It was under $20 at Wal*Mart.

    Hi, millerhouse12
    It could be the problem of file system on your SDXC card. Windows only recognize three file systems, NTFS, FAT32, and exFAT. Please make sure your SD card is of one of them. You can check that in Disk Management.
    If that is the problem, you can format SD card to FAT32 or exFAT
    with Disk Management or Diskpart and try again.
    Best regard.

    OP could read them before in September but not now. So it is not a compatibility issue.

    SDXC cards are the same size as SD cards. so don't need an adapter

    SDXC cards come pre-formatted as exFAT and my version of W10 should recognise that format and it would seem that it has done previously. It's quite an old reader but the PC was bought after 2008, so should also be compatible.

    @OP - Are you absolutely positive your PC was able to read/write to those cards previously? The fact that the reader in your PC can read an 8GB card but not the 64GB card leads me to suspect that the reader does not support SDXC cards but only SDHC and below.

    Yes, I'm pretty sure that the cards have worked previously on my PC. I bought a new video camera and was concerned about how I would transfer the information from the camera to my PC as that is where my Video editing program resides. My laptop doesn't have the same software so there would have been no point in testing the card transfer process there. As I said earlier, I've ordered an external reader which advertises SDXC as being compatible which I hope will prove or otherwise that there's something in the PC which is not working. I'll post the results on here when it arrives. I was hoping somebody might have encountered a similar problem as there has been lots of instances of problems with W10 & SD card readers.
