hey guys, ever since i got the time capsule (4th gen) I've been having problems backing data to it. i have a 21.5" iMac with Lion 10.7.4 and having my time capsule (1st gen) die earlier this year. now i keep getting this error every time it tries to back up. "The backup disk image “/Volumes/Data/Robert’s iMac.sparsebundle” could not be accessed (error -1)." i tried basic troubleshooting but nothing seems to work and it only seems to work when the iMac is turned on. my time capsule is connected via ethernet cable to my router and i recently placed a ethernet cable from the iMac to router because i noticed that the iMac doesn't automatically connect to the wifi. i looked though the settings and everything seems in order. anyone got a clue on whats happening and how to solve it?
