I have a Sony VAIO VGC-RC110G (Dual-Core) 3GHz, 1GB Memory, 250 GB Disk Windows XP Home (32 Bit).
System came with one 250 GB Serial ATA disk. The system had disk bays for three additional disks and I subsequently purchased 3 additional 250 GB disks for a total of 4 250 GB disks (1 terra byte). I installed the additional disks one at a time. The first 2 disks installed without incident, however, when I attempted to install the third disk it would not install. Is there a limit to the amount of disk space I can have with the XP Home (32 Bit) system. I now have 750 GB of disk space installed and operating without problems.
