Sounds like corrupt media.  Are you loading the driver from floppy?  If so, that would explain it.  Try:  full format of floppy disk, download driver again, run file to extract drivers THEN copy files to floppy drive.  Alternatively, use nLiteOS.com to integrate the drivers.  What Service Pack level is your 2003 media?  Which driver/file are you using?Are your drives connected to the onboard SATA ports or to a card?
We had a hard drive fail on our server and decided to replace both with larger drives. I created a raid 1 and made it bootable in the Adaptec utility.  When I try to install the server, it can't find the drive so I figured I needed to load the raid drivers first. When I try and load the Adaptec SATA2s driver I get the following message:  \aarich.sys has caused an unexpected error (4107) at line 2335 d:\srvrtm\base\boot\setup\oemdisk.c.  I can put the good hard drive back in and start up the server but I can't get the OS to load from scratch.  What am I doing wrong?
Can't install Server 2003 on SC1420 with fresh hard drives
