backup failing

[rdlsmith]

I have a routine backup using a sparse image that I run nightly. It works great.

Today, I thought I'd create another sparse image with Disk Util and run another backup that wouldn't get overwritten each night. I have about 78 Gigs to backup so I created an 80 Gig 128 AES encrypted sparse image on my LaCie Firewire drive.

Mounted the new image file, loaded a copy script and and things looked good. It failed with the following:

| 12:15:25 PM | Error | SDCopy: FTS_NS error for item: '/Volumes/LaCie Backup' err: 6, Device not configured
| 12:15:26 PM | Error |
2007-03-10 12:15:25.928 SDCopy[22156] FTS_NS error for item: '/Volumes/LaCie Backup' err: 6, Device not configured

I thought maybe the image needs to be bigger. So I made a 90 gig version. I also ran the Disk Verify and Repair within Disk Utility. No problems.

I restarted the copy script and it recognized that some data was already there but then failed again:

| 01:59:03 PM | Error | SDCopy: FTS_NS error for item: '/Volumes/LaCie Backup' err: 6, Device not configured
| 01:59:03 PM | Error |
2007-03-10 13:59:03.548 SDCopy[22472] FTS_NS error for item: '/Volumes/LaCie Backup' err: 6, Device not configured
| 01:59:03 PM | Error | SDCopy: FTS_NS error for item: '/Volumes/LaCie Recover' err: 6, Device not configured
| 01:59:03 PM | Error |
2007-03-10 13:59:03.548 SDCopy[22472] FTS_NS error for item: '/Volumes/LaCie Recover' err: 6, Device not configured


It looks like I was able to get 48.20 GB in the image file before the failure.

Any ideas?
