My mess when dealing with 2 iPods and 2 iTunes

I was a bitch shocked to find out that I couldn't simply copy my iTune database (living in my removable 320Gb harddisk) to either the removable harddisk (Z: on EeePC) or the D: Drive on my EeePC, and let it sync my iPod Touch with all the lastest Podcast and apps I downloaded at work.

The problem was not on the podcasts, but mainly on the apps. Futher investigation found out a few interesting stuff:

• While other items like podcast, music and audiobook remember items using relatively path, the APPS in iTune actually remember content using absolute path

After all my apps got wipped out, I had to rebuild them again. And then, I found out the best way to sync app and podcast on my EeePC:

• Create a folder in Z: and called it M
• Map m: drive to Z:\M using subst. I use M: because on my removable 320Gb harddisk, my iTune folder is in M:\
• Copy the whole iTune folder to the Z:\M folder
• Now the M: drive on 320Gb harddisk should have the same iTune folder and same path as in the virtual M: drive .
• Sync with iPod Touch.

It's not as straight forward as I wish it could be, but at least I did what I need to do.
