TonyP2002 Posted January 9, 2006 Report Share Posted January 9, 2006 I have Retrospect 6.0 on my Mac b&w G3, which is connected to a LaCie d2 160 GB external firewire drive, of which I do file backups. I also back up a client iBook G3 to the same drive, wirelessly. Unfortunately, I can never get a legitimate working backup of either. I usually have numerous Execution Errors, which can be eliminated after several time-consuming tries of backup sets. But worse, I get continual Chunk Checksum Errors on my Client backup, and in the past when I've tried to restore a file or folder from the backup set (even though the backup file is verified and shows not to need repair), I cannot. In essence, R6.0 has been useless for me so far. Any advice is appreciated. Link to comment Share on other sites More sharing options...
CallMeDave Posted January 10, 2006 Report Share Posted January 10, 2006 The FireWire bus on the original B&W G3 was sub-par, and is known to cause problems with FW devices. I'd advise you to acquire a high quality (although still not very expensive) PCI FireWire host adapter, and try your tape drive with it instead of the onboard ports.

TonyP2002 Posted January 10, 2006 Author Report Share Posted January 10, 2006 The external drive I have is not a tape drive but a 160 GB hard drive. Also, the firewire ports have tested well with TechTool Pro and I've experienced no other Firewire problems. R6 is the only app causing trouble. I hope that just getting this software to work properly for what it's intended to do does not require an additional hardware expense. I also read the knowledge base article that requires a system restart after every checksum error... is that what I'll need to do every time? Hopefully there's a solution for the issue since it's very frustrating buying backup software that doesn't back up... Link to comment Share on other sites More sharing options...
CallMeDave Posted January 10, 2006 Report Share Posted January 10, 2006 Quote: R6 is the only app causing trouble Retrospect is the only application pushing I/O through the FireWire bus hard enough to expose your hardware problems. Fact: your Macintosh model has known FireWire hardware issues. Fact: your FireWire device is exhibiting problems when used with Retrospect. Conjecture: your Retrospect problems are caused by the deficiencies in your FireWire hardware. >I hope that just getting this software to work properly for what it's intended to >do does not require an additional hardware expense. Retrospect requires hardware that works correctly; if you don't have it, you might have to pay extra to get it. Dave Link to comment Share on other sites More sharing options...
TonyP2002 Posted January 11, 2006 Author Report Share Posted January 11, 2006 Before I go out and spend money on a firewire card, that logic must be confirmed somehow. After all, just because there is a known firewire issue on my model (of which there were two revisions), doesn't necessarily mean there's a firewire issue on my particular machine. I'm not necessarily convinced that I definitely have it since I've done video editing via the same firewire drive (which pushes through loads of I/O as well) and haven't had a problem. I'm going to try backing up to a set on my internal drive, where no data will be passing via Firewire, and we'll see what happens. Link to comment Share on other sites More sharing options...
