Please DO NOT reply to the list and the poster. Where do you think I got your original request from? The list! And how any copies do I need in reply - ONE.

OK, so on this very rare occasion I forgot to wipe your e-mail address from my message, but what the heck are you on about getting my "original request from?"? What 'my original request'? I didn't make a request.

All I want you to do is to answer my question which is what problems are to be avoided by not putting a CDROM, or similar, on the same cable as a HD.

He was requesting that you not be so *rude*, such as sending him duplicate posts. So you send a 97 line *full* *quote* to a 3 line request. I am sure that you will receive a great deal of help. Perhaps you should try a baseball bat. -- Patrick Shanahan Registered Linux User #207535 http://wahoo.no-ip.org @ http://counter.li.org HOG # US1244711

Oh, is that what it was all about. And I thought it was something really serious and life-threatening. And it wasn't me looking for any help, by the way. I was simply asking for clarification of a statement. Cheers. -- I am not young enough to know everything.

The way I interpret a few technical papers I've read is that because of the technical characteristics of IDE it is not possible to read and write simultaneously on the same IDE cable/port. Putting 2 HDs on the same cable therefore gains absolutely nothing if one is transferring data between them - which is why I put my HDs as masters on the 2 IDE ports with the CDROMs/DVDRWs/CDRWs as slaves.

If you do speed tests on them using hdparm you will probably see they are quite slower that way - unless you are lucky. Experimenting is definite, theory is not. About your first question: /usr/share/doc/howto/en/mini/Hard-Disk-Upgrade.gz -- Cheers, Carlos Robinson

Further to my earlier response, I've now looked at this How-To and I can't see anything there to contradict what I said. The How-To talks about removing another device from the same cable to be able to install another drive (to copy the system from 1 drive to the new one) but this is in the context, the way I read it, that the controller is supporting 2 EIDE devices. The article is also written some 4 years ago (2000). I haven't read the article re hdparm so haven't yet done any practical testing. Cheers. -- I am not young enough to know everything.
