Hi there,
I have the exact same adapter on my Cyberstorm's MKII 060 SCSI interface for a few years now, a normal IDE HDD connected on the other end. I've had no problems with file access but it was picky about the jumpers on my HDD.
I then tried using an IDE->CF adapter on it, and I've had problems booting off it entirely: the reading LED would turn on and it would freeze there forever. It took me a lot of time of frustration and tests to figure out what was wrong, until I finally did: the filesystem on the disk (I was using SFS, when I reformatted the disk with PFS it worked right away).
I would recommend you have a look at the filesystem you're using at first, then perhaps another CF card if that's possible to determine if the problem is coming from there. Some are known to behave strangely...
Hope the above helps a bit!
