Crawling SCSI- 5 Mb per minute?

[Cyberbear]

I just wanted a confirmation that I'm not crazy.

 

 

 

I know I'm backing up a lot of data (~13 Gig) and that Retrospect has to compress, write and verify everything the first time, but should I be experiencing speeds of only 4.9 Mb per minute?

 

 

 

Setup: G4 450, 320 Mb RAM, Mac OS 9, Adaptec SCSI PCI card (no drivers), Panasonic 4x CD writer.

 

 

 

Thanks for any feedback or suggestions!

Your limitation may be the CD burner. Some can only write at 2x speeds. The following is from the Knowledgebase:

 

 

 

Retrospect loads it's own drivers to write to any supported CD-R drive. These drivers are written to work as efficiently and reliably as possible with the drive. There is no way to adjust the write speed, short of turning compression on or off.

 

 

 

Note that Retrospect writes in packet mode and will write data at the highest speed possible for your device. In some cases the firmware of a device will prevent Retrospect from writing data (in packet mode) at the normal designated write speed. This is true for the Panasonic CW-7503, Panasonic CW-7586, QPS Que! Fire 16x10x40 (TEAC) and a few other drives.

 

 

 

If you are having slow write speeds, it could be related to any of the following: client speed, network slowdowns, speed of the host, device communication, device firmware limitation or device problems.

Ok ... reasonable, since I purchased that CD-R to write high-quality audio CD at low speeds.

 

 

 

When do you think your developers will create a driver so that Retrospect 4.3 will support the SmartDisk firewire CDR? I'm kinda stuck, considering this is my only other device, and I can't use it with my Titanium Powerbook, either.

 

 

 

Thanks for your help!
