RE: Internal HD in External Enclosure.. I wonder if anyone can help - my situation is a little different to the previous post but runs along similar lines.. I had a LaCie external drive (FW400, 120GB) this was partititioned into 3, attached to an AGP DP450 G4 running X.3. One partition corrupted then the others, I tried to reinitialise after numerous recovery attempts but the disk was dead. Subsequently I purchased an internal drive mechanism which was the same manufacturer/spec but in 250GB flavour. I have read that my machine wouldn't see a 'big' drive internally so i put it into the external LaCie enclosure and re-connected it to machine. Disk Utility attempted to format this per my instructions but hung after one third of the progress bar. Every time I have tried since I get an input/output error or it hangs in the same place! Could the Firewire board be damaged? Is there something I'm missing? Does anyone know of a link/document where I might find comprehensive instructtions for fitting it internally(jumper settings, etc)? Incidentally, I have also hooked it up to an XServe and tried formatting it on there and it does the same thing. Any help would be greatly appreciated as this is driving me nuts and I have LOTS of work to catch up on..
