The keyboard smoked while Ivan typed to All:

 IW> I was wondering about some of the strange differences between IDE and
 IW> SCSI and if i can fix some noticable differences.

Hopefully I can help a little at least.

 IW> History:
 IW> I have had 5 SCSI drives on my A3000 for about 3 years.

Green envy....   :)

 IW> I now have transferred everything to my A4000, i have 2 IDE drives.

Green turns deeper shade... :)

 IW> OK. Firstly it seems that if i resume downloading a file using an FTP
 IW> program, it crashes, no explaination. No change in software, just
 IW> hardware.

I suspect this has more to do with the 040 rather than the HD change.

 IW> If i have a large directory, reading the directory is very quick, much
 IW> quicker, but if i am to copy a file into a directory that has a lot of
 IW> files, say more than 400 files, then i find the copy process is
 IW> speedy, but the actual searching part is damn slow, like it is trying
 IW> to find a place to copy the file or something, it pauses at the start
 IW> and end of the file for anything up to 3 seconds when it was instant
 IW> with SCSI drives. Can be a pain when copying several files at once.

 IW> When i formatted the new IDE drives, i did select directory cache
 IW> which i do not think i did on the SCSI drives, could this be a
 IW> problem?

Directory cacheing will enable you to read the directory listing damn fast.
That's what it's there for. But I suspect you'll find that the slowness of
writing files is a demonstration of the difference between the interfaces.

 IW> What's the safest addbuffers amount you should have. If i have 100
 IW> buffers set in HDtoolbox on each drive, should i still addbuffers in
 IW> startup-sequence and how much is too much, i have plenty of memory
 IW> (about 10 meg free after bootup)

Fill yer boots! I don't think there's any real limit of buffers you should
or could add, but whether it will help, I'm afraid I'm not sure. I suspect
you will notice a difference when you are writing large files if you have
lots of buffers, but for lots of little files, I don't think it will help
much.
