I have a similar problem
I have two computers and an iPhone and I use the iPhone as the conduit through which I keep the computers in sync. It worked for 18 months, now it doesnt. The iPhone calendar will always be replaced by the computer calendar even though I always choose merge.
What has changed in my set up over the past couple of weeks is going from 10.6.3 > 10.6.4, updating to iTunes 9.2, and getting an iPhone 4 with iOS4.
Same problem here. As a Mobile Engineer I use my iPod Touch to store appointment info. Periodically I backup to iCal on my MacBook. Normally I get a message advising I'm changing more than 5%, and asks if I wish to continue. However on my last attempt no such message. As the Sync began, it looked and felt different, so I cancelled. But it was too late. The last 3 weeks of data was wiped from my iPod, as well as upcoming appointments. Massive problem.
The only change I believe I've made since my previous Sync is: upgrade to iOS 4.
I'm in the same boat. I sync my Touch to my work computer, I get all my events from that iCal. I then sync to my home computer, hit the "Merge data" option, and everything that's on the work computer disappears from the Touch, and doesn't show up on the home computer. Go back to the work computer, and it's back.
This all worked until I loaded iOS4.
New appointments I enter on my Touch won't show up in iCal.
If I enter in iCal it shows up on my Touch.
I have found many appointments on my Touch not showing up in iCal.
All this time, probably since upgrading to 4.0, I have been syncing I have trusted that
the Calendar from the Touch to iCal was backing up.
One other issue I noticed as well. Since the upgrade every time I enter the Calendar from my Touch
their is a delay before it loads.
Somehow I feel like it's an issue with the "merge" function on iTunes. If I create an event on my iPod and immediately sync it with one computer, the event is transferred/merged from iPod to computer and computer to iPod. If I then take that same iPod and plug it into my other computer, the second computer writes over the entire iPod calendar, even when "merge" is selected. Even the event I created previously that transferred to the first computer is deleted.
Then I decided: well I could merge my work calendar from my work computer, and merge my home calendar from my home computer, and at least try to keep those synced on the iPod. But when I deselect any calendar in iTunes, it then deletes that calendar from my iPod as opposed to just leaving it as is. Bizarre...?
I figured out a simple solution...
When I first synced, I had it set to "all" calendars... this caused the original problem I posted here.
Next time I selected my calendars individually... I checked the boxes next to "home" and "work"... it synced perfectly then.
I found your solution worked perfectly, even under iTunes 10. Strangely, none of my new synced data would show in my calendars after syncing with the cloud(MobileMe) using wi-fi. Even with wi-fi Turned Off, as soon as I unchecked all calendars, and started adding one calendar at a time, the data mysteriously appeared. Apparently it was downloaded, but does not refresh and display until I checked one calendar at a time until all the current events displayed.
Thanks for your tip!
Well I called an Apple rep and while troubleshooting performed another Sync and all the accumulated iCal appointment entered on my iPod Touch magically displayed on my Mac's iCal software.
Unfortunately the Apple rep had no record of a One Way sync issue so the only two conclusions I can manage for now are:
1) I called the iMagic Rep at Apple
2) even though I performed a sync after installing iTunes 10 recently and iCal still was not syncing with my iPod Touch I may have rebooted my Mac since that test thus resulting in the situation resolving itself.
If you have this issue try installing iTunes 10 then reboot your Mac then Sync you iPod Touch with your Mac. Hope this helps someone.
