How do you stop your hard drive taking memory

spannernick · 18 June 2016, 12:28

Hi,If I load a AGA game from my Gotek and the hard drive is active it comes up with out of memory,is there a setting I can change on my hard drive(its a CF btw) to stop it using up memory..?

Is it the max buffer or something..? I don't want to wipe my hard drive .

If your drive is partitioned in several partitions, you can disable one or several in the early startup menu. Otherwise, you can change the number of buffers in HDToolbox. It's a non-destructive process.

What about disabling hd from early boot menu?

If you plan to use machine without plenty of fast mem, you shouldn't use that big buffers on partitions. I think something like 128 is quite enough in real use.

I myself have put more than enough buffers on my Amiga with 128MB fast mem, but once when I disabled the accelerator, it all went for HD buffers :P I used to have block size of 1024 bytes and then 600 buffers or so, so it took 600k per partition, and I had many partitions

2MB of chip mem alone wasn't quite enough :P

The buffer setting for each partition tells the OS how much memory to use for a buffer. The amount of memory that takes is:
(number of buffers) x (partition blocksize)
So, with 100 buffers on a partition with 512-byte block size, 51200 bytes (~51KB) are required. But 100 buffers with a 32KB block size will take 3200KB (~3.2MB). Reducing buffers will save you some RAM but reduce the performance of those partitions. Disabling partitions as already mentioned is an easy way of getting the RAM back temporarily.

You can also do AddBuffers "" -1000 in a script for special cases when running memory tight, but do have at least 30 buffers on the partition you are working, or things will go very slow, especially on ffs.

Disabling from ESM is the only thing that will work. I remember games like D-Generation of Heimdall 2 needing this to be done.
