Hi! FIO is a wonderful tool. Great work!! In the documentation (readme + fio.1 files) is this description: “On Windows, disk devices are accessed as `\\\\.\\PhysicalDrive0' for the first device, `\\\\.\\PhysicalDrive1' for the second etc.” This is predicated by this description: “Each colon and backslash in the wanted path must be escaped with a '\\' character.” In the case of Windows (Server 2019), the extra ‘\\’ is not required. My (successful) job file appears as such: [readtest] blocksize=1M filename=\\.\PhysicalDrive1 rw=read direct=0 #raw=1 buffered=0 #size=1G thread=1 I would be grateful that the documentation be updated accordingly. Thank you! Adam
