(z slaps head, should have checked this) In Server Manager/Disk Management, Windows had the disks marked "offline". Setting the disk online, which makes it appear there as "not initialized", allows writing. Funny that you can read from an offline disk w/o error. (Also, just setting the disk online with diskpart does not do it, had to use the GUI. Not going to investigate that at the moment.) Is there any convenient way for fio to check that status and report an error?
