PC won't recognize extra hard drives (edi) primary is SCSI drive

  1. This is my first attempt at building my own pc so forgive me if this is a silly question.

    This pc has an SCSI as the primary drive (17gig) and I'm trying to add two 320g drives that are edi drives.

    I added a new dvd drive, video card, and usb 2.0 card and those all work fine.

    I tried the drives set to slave as well as well as cable select. I even removed one of the drives so that the only connector is the edi slave connector.

    Am I having a problem because I'm trying to use an SCSI drive and the two edi drives? Do I need to use one or the other in order for this to work?

    Any help would be greatly appreciated.

    Let me give a little more information if it helps. The computer is a Dell Precision 530 Workstation. Company upgraded all their pc's and sold off the old ones for $50 each. I want to ue this as a media server for my home network.

    It has a 17GB SCSI drive on it now that has my Windows XP Home Edition and a few other programs on it. I was going to keep it for exactly what it does now. Basic everyday pc duties.

    I wanted to add two bigger drives for storage. The mother board has an SCSI connector and two EDI connectors. The secondary EDI connector is connected to the DVD drive and the CD drive. Obviously I don't need both but just left the cd drive in there since it wasn't hurting anything. Those both read and work fine.

    I have the two 320 GB storage drives connected to the primary EDI connector.

    The ribbon cable attached to the SCSI main drive have three unused connectors and another device attached to the connector on the drive that appears to be an active connector. I have no idea what the connectors do but I did a search on the web and what I have looks like a picture I saw of an active connector. That may or may not be right. Just trying to give as much information as I can. I have also updated my profile to give as much detail as I could on this system.

    I thought this would be a simple plug and play deal but the drives aren't being read. I no PC expert by any means but I hit F2 when the system was booting to see if I could find the drives showing up anywhere. Not sure what I as looking for but it did list the main drive durin boot up but not the others.

    Ok now I tried to take the SCSI drive out and just go with the two EDI drives and reload WIndows XP. XP went through it's set up process and when it was done the computer restarted and the two drives don't show up and I get a disc read error press ctl alt del to restart...when I do that I get the same result.

    I'm at a loss on what I'm doing wrong.

    Hold on a minute... edi you mean IDE or eIDE don't you?

    SCSI hard drives need to have terminated cables. IDE cables do not use termination. I would ditch the SCSI, but you will have to get into the bios settings and change the primary boot drive settings

    sorry yes meant IDE

    the SCSI does have a terminated end

    not sure what I did but it's all working now.....after taking the SCSI drive out of the loop and getting nowher I put it back in, hooked it up and booted up and both drives are now there....no clue why that worked when it didn't work the other times...not going to complain since it's working

    Chalk it up to a loose connection... Good work

    Happy Computing!

    well I might have spoken a bit too soon

    both drives are there but for some reason one of them has 415mb on it but there are no folders at all....I went into add/remove programs and all the programs that are on the smaller SCSI drive show up in the new drive as well

    are the two drives somehow linking together and information is being added to both drives?

    I did a test and removed a small program that I don't use much and it deleted it from my primary drive as well

    The only way this can happen is that there is a RAID (Redundant Array of Independent (Inexpensive) Disks) array set up on the system.

    The SCSI drive may be connected to a SCSI RAID adapter card. In RAID data is "mirrored" to all the drives in the array

    good grief....is this easy to undo? this isn't what I intended at all

    "Let me give a little more information if it helps. The computer is a Dell Precision 530 Workstation. Company upgraded all their pc's and sold off the old ones for $50 each"...

    I'm afraid large companies used RAID for data protection. You may be able to remove the SCSI controller and use the remaining IDE drives. The existing data may not be any good though

    ok thanks....i guess i'll leave it as is since they are at least all working....i don't mind having the stuff from the smaller drive being mirrored onto the larger drives...as long as it doesn't copy anyting I put on the larger drives to the smaller one I should be ok
