rshrieve Posted February 13, 2006 Report Share Posted February 13, 2006 Mac OS X 10.4.4 Blue and White G3, 896mb RAM, 400mhz Built-in firewire 400 bus LaCie d2 Big Disk Extreme firewire external HD Retro ver. 6.1.126 Driver update ver. 6.1.3.101 1. I am consistently getting "miscompare at data offset" errors on hundreds of files when I back up to either one of TWO LaCie d2 Big Disk Extreme. The largest number of errors are usually associated with backing up .jpg and .mp3 and .mpx files. I checked to see if the HD driver was up to date with a LaCie utility and it is. 2. Using exactly the same firewire port and cable, I can backup successfully to an Oxford 115gb external HD, only getting the usual date and time miscompare error msg on a small number of files. Unfortunately, this drive is too small to backup all the Macs on our network. Does anyone have any ideas on what is going wrong? Thanks for any help.

That might explain why it works with the smaller drive but not the larger. I'd suggest getting a FireWire PCI host adapter and using that.

rshrieve Posted February 13, 2006 Author Report Share Posted February 13, 2006 Dave, thanks for the tip. I do have a firewire pci card and will switch the LaCie disk over to that one now. Will let you know how it goes. Hope it's something as simple as that. What is the problem with the built-in firewire on the Blue and White G3?

The problem is that it almost works as intended, but not fully. Sorry, don't know any specific details. Regards Lennart Link to comment Share on other sites More sharing options...
rshrieve Posted February 14, 2006 Author Report Share Posted February 14, 2006 Thanks for guidance, Dave. The Blue & White G3 is now backing up normally to the 500gb external drive using a Firewire PCI card instead of the built-in firewire port. By the way, can I install the FW pci card in the first expansion slot on the B&W? It runs at 66mhz versus 33mhz for the other three slots. I am running the box headless so I don't need to have the video card in the first slot and can move it to another. If I do move the FW card to the faster slot should I expect to see faster throughput? I'm back in business with backups! Thanks, Rich Link to comment Share on other sites More sharing options...
