Jul 17, 2015  If the drive is large enough you can install Windows 10 there but it must be formatted NTFS. Vista and later (including Windows 10) can only be installed on NTFS. Or GPT in case of UEFI Bios. Basically it seems that support for exFAT is the stumbling block for some devices. For a device to officially support large SDXC cards it must be capable of reading and writing to exFAT formatted. ExFAT is supported in Windows XP and Windows Server 2003 with update KB955704, Windows Embedded CE 6.0, Windows Vista with Service Pack 1, Windows Server 2008, Windows 7, Windows 8, Windows Server 2008 R2 (except Windows Server 2008 Server Core), Windows 10, and Mac OS X starting from 10.6.5.

SOLVED Hey Reddit, i seem to be having some troubles with the ExFAT file system in Windows 10. My version of the OS is Win10 Pro x64. i have a usb with a ton of music and a copy of Windows XP Pro 32-bit meant for Oracle's VirtualBox. The usb is 8Gb and i formatted it on my macbook running OSX Mavericks for ExFAT because this seems to be the only available file system that is (supposedly) compatible with both windows and OSX yet windows recognizes the drive but says that i need to format it to use it. Pls halp. i know that you can format the drive for NTFS and enable that file system on OSX but i cant enable NTFS on the mac because the command prompt is blocked by my schools tech administration (got the machine from my school). how do i get windows to recognize ExFAT and allow me to read and write with this file system? TL;DR How do i get windows to recognize ExFAT and allow me to read and write to this filesystem?

EDIT: turns out that the ExFAT filesystem tool that i used to make the partition made it so that the partitions made with it would be locked after a set trial period. that period had ended and locked the partition from being used.

exFAT (Extensible File Allocation Table) is a file system introduced by Microsoft in 2006 and optimized for flash memory such as USB flash drives and SD cards.[5] exFAT is proprietary, and Microsoft owns patents on several elements of its design.[2]

exFAT can be used where NTFS is not a feasible solution (due to[50] Unlicensed distribution of an exFAT driver would make the distributor liable for financial damages if the driver is found to have violated Microsoft's patents.[55][56] While the patents may not be enforceable, this can only be determined through a legal process, which is expensive and time consuming. It may also be possible to achieve the intended results without infringing Microsoft's patents.cf.[57] In October 2018, Microsoft released 60,000 patents to the Open Invention Network members for Linux systems, but exFAT patents were not initially included at the time. There was, however, discussion within Microsoft of whether Microsoft should allow exFAT in Linux devices,[58][59] which eventually resulted in Microsoft publishing the official specification for open usage[7] and releasing the exFAT patents to the OIN in August 2019.[42]

Notes[edit]

  1. ^ ab Although Microsoft published a different value in KB955704, the file size is in bytes and is stored as a 64-bit number. The largest theoretical file size would be 16 EiB−1 byte, the same as in NTFS. However, since the true theoretical maximum volume size under the current specification cannot exceed 128 PiB, a file can never reach that file length. Another reason for the limit is that current IDE/ATA disk addressing is LBA-48, and uses a 48 bit block address to address a sector. A 512 byte sector size would make the maximum addressable file system 512 × 248 = 257, which is 128 PiB. In other words, the 128 PiB limit on the architecture is a hardware restriction. This scenario does not include AF (4k sectors) and exFAT is limited to 128 PiB regardless of sector size based on the specification.
  2. ^The theoretical maximum volume size is defined by up to 232 − 11 possible clusters with up to 225 − 1 bytes per cluster = ca. 128 PiB. The size is currently also limited by the LBA48 addressing scheme, as with a 512 byte sector size, only 248 × 512 = 257 bytes = 128 PiB can be addressed.
  3. ^This limit applies because the maximum directory size is 256 MiB.
  4. ^ ab268,304,373 files = 228 − 11 reserved clusters - 131,072, the minimum number of 64 kiB clusters occupied for the 268,435,445 directory entries (á 32 bytes) without VFAT LFNs, which are required for 268,435,445 files with sizes between 1 and 65,535 bytes. With VFATs, the 131,072 number must be multiplied by 21 (worst case), which would result in 265,682,933 files instead.
