The original poster never stated whether or not the 4 drives he purchased were new or second-hand. It is very possible to buy used drives off ebay (or any computer store that sells re-used parts) that are listed in "working" condition, only to have them arrive at your house, and after installing them find out they dont' work. Because it happened to me numerous times, not just with CD-Roms, but with modems as well. I don't think the odds are anywhere remotely close to "microscopic." If you factor in the following variables: damage from the post office, not marked as "fragile", the person selling the item didn't test the drive, it was dropped by the mail workers, it was too cold outside, too much moisture/humidity in the mailbox, etc etc etc.
It's not a microscopic possibility of getting 4 consecutive broken CD-Roms....if.... they are used, that is.
Until we have ALL the facts, especially concerning the "newness" of his CD-Roms, and how much human error it takes to become "Radical," we don't know how microscopic the odds are. Period. Anything can happen. Maybe he DID get 4 broken drives in a row.
Not trying to be a jerk about this, just trying to be methodical.
I like methodical. If I stuck four new or used optical drives in a row into a computer and they do not get recognized I will then give my full attention to everything other than the drives. Cables can be defective. Ports ( interfaces in this case ) can be blown. A myriad of BIOS settings can be FUBAR. But most common, and the first place to go at this juncture is making sure the jumper matches the cable position ( but also remember what Jaclaz mentioned about Cable Select ).
One drive bad can easily happen. Two, I can also accept. Three is Clark. W. Griswold bad luck
. Four is getting close to lightning strike chances. Again, this is regardless of new or used since it happens either way in my own experience.
Radical human error might be jamming the IDE cable in upside down and having a pin smashed by a keyed filled hole or something else.
Of course we both know that the solution is to take these so-called bad drives and drop them in a machine that is working. Also, I didn't mean to imply that there is zero probability of four bad ones in a row, it is definitely non-zero, but I'll stand by Microscopic probability on this one.
, sorry if I missed it, but did you mention the motherboard model and BIOS? Is there any chance of a screenshot of the first BIOS page, the one that shows the hard drive and other IDE positions.
the setting "Silent Boot" mentioned by LoneCrusader can also by worded differently. "Fast Boot". "Intel Logo" ( or Compaq, eMachines etc ) or other phrasing. He is talking about the setting that bypasses the DOS information messages and instead shows nothing or an Intel logo or OEM branding. That DOS screen should show you if it is being detected or if there is some delay as it tries to enumerate it. Anyway, I am not clear on what you tried. I would first try master on secondary channel ( end of 2nd cable ), then slave on secondary channel ( middle connector on 2nd cable ), then slave on primary meaning the same cable as the boot drive ( middle connector again ) if it is physically possible to do this ( tight spaces, etc ). Trying these three possible positions means moving the jumper to match.
There is a less probable case that the motherboard is a real fast booter and tries to enumerate the drives before they have a chance to spin up. This can be fixed by setting the memory test to NOT "quick" and while it rolls through all your RAM the hard drives have a chance to complete power-on. If you get my meaning, then you will also understand that you can optionally just warm boot immediately after a bad startup ( optical not recognized ) by immediately doing ALT-F4 and RESTART in Windows.
