Hi, can anyone please explain what is dynamic disk? Well Im using Windows 2000 Pro. Abit KX7-333R IBM 40GB 7200 rpm Quantum 3.2GB 5400rpm Yamaha 16/10/40 IBM on primary:master has 4partitons 1st FAT32 (w2k) 2nd FAT32 (mp3) 3rd FAT32 (kazaa+backup) 4th NTFS (pagefile [swap]) Quantum on secondary:slave has 1ntfs partition Both of the raid ide is not used. Is dynamic disk something like raid? I read the help files by M$ but still cant get a clue what dynamic disk is.... Whats the advantage and the disadvantage?
