The problem is not that the timeout values are too short, it is that AROS does not wake the devices when they are put in a low power state.

Sure, making the timeouts larger might alleviate the issue a little, however at some point the devices will still get powered down unless you are using them constantly - And will not be usable again until the machine is reset (note: just restarting AROS will not bring them back to life).

I also have not encountered a situation where this occurs until you have atleast reached the desktop environment (e.g. Wanderer) - So I would suspect something else is amiss, perhaps the SATA controller is not AHCI compliant.

You would be best to boot AROS to the early startup menu (add bootmenu to the boot command line) and check if the devices are listed at all.

Edit:

There are also issues with some CD/DVD Writers where the device is not exposed as the type AROS expects (they act more like hard drives), and so it does not try the correct filesystems on them. This does show the symptoms you experience, since after loading the kernel AROS no longer then sees the media as bootable.
