Well, I know this has been discussed quite recently, but at the time I wasn't paying too much attention. However, for some reason I ended up buying a 30 meg Supra HD for my A500 [well, other manufacturers' HD:s for the A500 just aren't available in Finland]. I want to know if anyone has succeeded in Mounting (and Formatting) this drive with non-Supra software (this possibility is mentioned in some readme-file, but no required technical information is given, though). I have tried a couple of times but have been unsuccessful so far. One might ask, why I'd want to do it. Actually, the salesman at the store where I bought my drive from did just that - and could not give any information :-( First, I just like to know things. Second, SupraMount seems to be leaving a CLI-process hanging around, which I can't get rid of by Breaking. Has anyone else noticed this 'feature' - I suspect that SupraMount spawns a new CLI- process to Mount the additional partitions after DH0:? BTW, SupraFormat shows that my drives are formatted with an interleave of 3. I think (based on Supra's ads) that one can use 0 interleaving with the 30-meg Supra drives/conrollers. Am I right? Can I damage things if I use too small interleaving? I doubt that I can cause any physical harm, BUT will it cause unreliability and/or soft errors? So, if some-one has succeeded in this, I'd be grateful to receive the information needed in building my mountlist. An example of your own mount- list would be really nice. Please, email preferred.

About Mounting a Supra Drive. I talked to Supra today, and they are doing a rework of the drivers to allow this. David Childs

You should be able to just create a MountList entry for each of your
partitions, then use the AmigaDOS Mount command to mount each partition. The
A500 and A1000 versions of the Supra interface do this quite nicely. You'll
also end up saving about 10-15K per partition. Use a MountList entry similar
to the example on the 1.3 Workbench, but change the device drive name to
either harddisk.device or scsidisk.device, depending on which drive you have.

You can use a smaller interleave easily enough, just do a low-level
format with a smaller interleave, the only result you'll see is slower read
and write speeds. The interleave of 3 seems to be best for most drives with
the 500/1000 controllers, an interleave of 1 is best for the 2000s DMA card.

If you can mount the Supra drive without Supramount,
why does Supramount now exist?

So you can mount all the drives at once... No need to do
a seperate mount for each partition. Most of the users who're buying
hard drives don't really want to have to build mountlist entries and
do lots of editing to the startup-sequence. SupraMount allows them
to use a hard drive with minimal hassle.
Note that the newest version of the Supra software allows
you to select (during the format/zero process) whether you want each
partition mounted with SupraMout, or whether you want to manually
mount it. That way you only need to mount those seldom used partitions
when you need them... (Assuming you have enough disk space to *have*
seldom used partitions! :-} )
