I saw an OSR article inviting people to email questions about Windows file system driver development. After emailing OSR, Dan Root suggested that I post my message here. I'd like to ask if anyone can tell me a bit about writing a GPT driver for Windows XP. I realize that's a little different because it's a partition table rather than a file system, but I know it's possible because Paragon used to offer such a driver.
I know Windows XP supports 48-bit LBA, but I remember hearing that the 32-bit version can only use 32 bits out of 48. Is it possible for a driver on Windows XP x86 to address hard drive sectors using all 48 bits? If so, how hard would it be to write a GPT driver for Windows XP?
