My computers haven't been backing up correctly for a while, so I've been trying to fix the problem over the holidays. I have a 1G Time Capsule, and a Western Digital HDD connected using the USB port. I decided to start from scratch, so I wiped the drive several times, and zero-ed out the data so it's definitely "clean", but when I try to back up my computers it fails after a little while, normally saying something about losing connection to the drive. When I try to restart the backup, it comes up with Error 22, saying that 'the sparsebundle cannot be created'. I've updated the firmware to 7.6, and my Macs are all running 10.7.2. I used to have several drives connected to the TC using a USB hub, but took that out thinking it might be the cause of the problem and it hasn't helped. I think (although can't be positive) that the issue started around the time I installed Lion, although one of the computers was bought after the issue started. If anyone has any fixes or ideas that might help, it'd be very greatly appreciated!
