Scenario- with 4 250GB drives raided (actual is 948Gb) -it works. With 4 300GB drives it does not. With 3 300Gb drives it boots and works The C: partition in all scenarios was 20GB. I usaully partition 350 for apps, 400Gb for games, and the rest for files, movies, CD copies, etc. Yes, I also tried one big C: partition, but that did not work either. Anyhow. Microsoft won't help me on the issue unless I pay their hourly server support fee. The problem occurs on Win 2003 Ent Srv both 32 and 64 bit flavors. The Suse build has no problem with the size and loads great! Just Windows is the b***h. Any ideas? Remember, it is not hardware or config, if other OSes are OK with it. Remember that it breaks only when I brach the 1T threshold. Here are my rig specs: Dual Opteron 250 8GB ecc ram (fastest) tyan s2885 board, latest bios 6800 Ultra Nvidia Win Ent Server 64 latest released build (4) SATA RAID 300GB drives (over 1 Terabyte storage) Dual Layer DVD burner Thanks in advance for any help you render.
