VFAT mounting inconsistency in UEFI

VFAT mounting inconsistency in UEFI

[GN Keshava]

Hi,

I'm connecting my Linux device to UEFI-running PC using USB Mass storage.
Linux is enumerated as Mass storage on host (UEFI).

Sometimes, the mass storage is not detecting/mounting on UEFI.
Linux has partitioned it as VFAT. It is always being mounted on
Windows/Linux.

Has anybody tested this?

Thanks.
With regards,
Keshava

I thought VFAT (Win 95) was a subset of FAT32. The EFI FAT driver is coded to the FAT32 spec. Microsoft Extensible Firmware Initiative FAT32 File System Specification <https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0ahUKEwi6yP2X2dHQAhVK1WMKHbFdDT0QFggbMAA&url=http%3A%2F%2Fdownload.microsoft.com%2Fdownload%2F1%2F6%2F1%2F161ba512-40e2-4cc9-843a-923143f3456c%2Ffatgen103.doc&usg=AFQjCNHLIvOURM1sLTaA9eBEKIcSRQcfpA&sig2=KLirxjetmNEsuXdnVC3ETg&bvm=bv.139782543,d.cGc>
