Missing Modem RCA dhg525

I've just formatted my hard drive. I installed windows XP but my modem is not showing up in the device manager. I tried using "add hardware" but windows does not recognize it. (I didn't get any software when the modem was installed.)

Any help would be mush appreciated.

Uhhh no, well since you reformatted your computer i see, then you must get an installer drive cd from your internet service provider (ISP), (and if you have time warner cable like me, then you could get it for free if you ask them at one of their offices, or you could call them, and they can come over and install it for you) because since you are connecting though a USB connection, you need that installer cd driver to let your computer know that that modem/router is there. ethernet should work directly without and installer cd driver, but sometimes it doesn't work.

Take the modem out and look for any brand names such as aztech etc and look @ the chipset to discern what kind of modem it is.

If you don't need the modem, you can safely disable this questionmarked device in Device Manager, so it does not nag you every time you start Windows.

As far as the disk is concerned, you may try going to Disk Management (in XP you right click My Computer and choose Manage, a Computer Management window will show Disk Manager will be on the list near the end).
Study the list of volumes listed in Disk Manager; if you see a volume of more-or-less the same capacity as your ext. disk, and without a drive letter assigned, than right-click that volume and choose Assign / Change Drive Letter. Choose a letter farther into the alphabet so it doesn't interfere with any existing volumes - my favorite is X: for eXternal :) - and confirm.
After that operation the drive should appear in My Computer.

Wound up reformatting the hard drive and installed Windows XP Pro 64-bit. But am missing correct drivers for the modem. It does not even show up in device manager

Hi activebiz,
I see you re-installed Windows on the machine with Win XP Pro 64bit but you are having issue with the driver as mentioned.
If I may ask before you installed win XP 64bit did you have win XP 32bit?
If so then try downloading a driver for a 64bit version to make the Modem driver work, having an Incorrect version of the driver will really not show up in device manager, and make sure the driver you are downloading is the correct driver.
You did not mentioned the Brand of the Machine or Motherboard that you have and the modem that you need a driver for is that a built in Modem on the Motherboard or is that a modem external provided by your Internet Provider.
