Not sure this is the same issue, but I tried to use a western digital as an internal hardrive with a G4 400 (Still on system 9 with Premiere) and had crashes and never could download video onto the internal western digital or when it was dumped into an external. So now I only buy IBM/Hitachis which work great (4 X 120GB's) and will download dv both internally and externally using an older external firewire case and older firewire chip. Plus they're the only ones that still have a 3 year warranty at stores like OWC and a few other stores. One day I'll try a Seagate and or a million hour Maxtor. Lynn
