sdhc works fine in my '13 vpap.archangle wrote:The ResMed SD card FAQ says speed doesn't matter. However, it also says SDHC won't work, which is wrong for many machines.
rebe, your machine is more recent than either of my S9's that do accept SDHC. If you've got any other SDHC cards, for instance, for cameras, try them if you would.
One thing I've found over many years of working with SD cards is that even when the specs are correct, some SD cards just won't work with some devices.
that's good advice about trying different ones, I ran into that issue recently with a gadget that was very picky about what microsd it would take.
