Some external hard drives don't support the sync command even though the hard drive has write cache enabled. In this case, upon suspend request, sync cache failures are ignored if the error code in the sense header is ILLEGAL_REQUEST. There's not much we can do for these drives, so we shouldn't fail to suspend for this error case. The drive may stay powered if that's the setup for the port it's plugged into.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
