- Talking with other BridgeBoard users I have found that some of them have
- avoided using JDisks. Partly some have been misled by the BB manual into
- thinking that if they don't unlink the JDisk after using it, they will
- corrupt it or won't be able to get rid of it. This isn't the case. Once
- you do a reboot, it can be relinked or deleted. Most of the time I never
- even bother to unlink it when Iam finished using it.
-
- Another complaint I've heard was that the harddisk based JDisk was too
- slow. The secret of using harddrive based JDisks is to use a large number
- of disk buffers (500->800). These can be added by using the AddBuffers
- command (eg. AddBuffers dh1: 600). You could add this statement to your
- startup sequence or just issue the command from CLI when you need it.
-
- I have found that the big advantage of using JDisks is that I can setup an
- Amiga type CLI environment on the BB. I can make a JDisk in Amiga RAM: and
- link it to the PC, say to drive D:. Then I can go to drive D: on the PC
- and be operating in a RAM disk environment. Since JDisks can easily be made
- of any size, they are much more flexible than PC RAM drives and you don't
- have to alter config.sys to create them. Also, since you are using Amiga
- memory, you don't lose any PC memory like you would if you created a RAM
- drive on the PC. I have found that using the Amiga memory via JDisks is
- almost as fast as using PC memory.
-
- I usually create the JDisk in recoverable ram (in my case VD0:). This way
- if the PC crashes, I can do a reset, relink to it to the Amiga recoverable
- ram and not lose anything. I have also found them to be useful when running
- programs on the PC that insist on writing to your harddisk before they
- will run. I just direct them to the JDisk. Using MakeJD, ReadJD and WriteJD
- makes it very easy to create JDisks and transfer data between the Amiga
- and the PC. So if you have been avoiding JDisks, give them a try, you might
- find that they can really enhance your PC computing.
