2nd Internal HDD Not Showing Up in Windows

  1. Let me preface by saying sorry if this is a stupid question and/or I do not provide enough information.

    I have a Dell Precision 390 desktop that was running XP Pro until I switched it over to Windows 7 to test it out. I have two WD 160GB SATA drives inside of it. When I start the computer and go into the setup to look at what drives are enabled, it recognizes the two different drives. Once I boot into windows it does not recognize the second drive. I have tried switching the second drive to different ports to no avail. I used a new OS Install disc to see if it would show the drive in case it needed to be formatted and it still did not show the second drive. I can hear the drive spinning just fine. I have a Sabrent Cable Converter that I can plug into the USB Port to see if it shows up that way using Active Recovery Partition software if anyone thinks that might help.

    Any ideas or thoughts would be much appreciative. The people at Dell told me to send the whole thing in. Let me know if you need anymore information.

    do you have the jumper settings correct? I would hope that this is not your only computer as windows 7 is a beta version. this could be your problem. does the secondary drive show up in bios?

    No it is not my only computer. I was also running XP Pro before and ran into the same problem. The secondary drive does show up in Bios. The jumper settings are the exact same on both drives.

    you should have one of them as a slave.

    Master and slave do not apply to SATA drives.

    Already tried that but thanks! Disk Management only shows the C Drive, my External,and my CD-Rom drive.

    Any other ideas?

    This is interesting. I turned off the computer, and plugged the 2nd SATA drive into the ports for the 1st one, and booted the computer up, somehow the second drive is designed to mirror the first one in case the first one goes down.
