Recover Bookmarks, Mail, iCal and more after HardDrive upgrade I have allowed myself a new SSD HD for my MacBookPro.
Now since i had a case-sensitive HD (don't aks) and i wanted to get rid of it and also finally install Lion, i didn't copy the image of my old system.

Now i want my old iCal prefs and Mail Accounts. Also i would like to have my bookmarks from chrome.

I have the old HD in a case so i can plug it in and use it as an external harddrive.

I tryed just copying the whole Library Folder - didn't work.
Any Ideas anyone?
Though not a selective copy, you could use Migration Assistant (under /Applications/Utilities) to copy your entire user data from the older hard drive to the Mac. Turn off Time Machine before doing this (to avoid unnecessary backups and slowing down the migration).

Since you already have the user account and Migration Assistant has created a second account, there is no simple way to merge the two accounts (definitely not the configuration used by various applications and the data, since there may be conflicts). But you can copy over data across from the individual folders under the home directory (and somewhat tediously, application data on an application-by-application basis).
