Problem with Leopard

[gowthamn]

I migrated to OSX 10.5.1 from 10.4(Tiger) and Lifes been miserable ever after.
I am stuck in no mans land hoping to recover my data.

So I created a new profile on Leopard with my username and transferred all my data onto it (~56GB) and it all worked pretty fine for couple of day with just few hangs here and there. so confident of leopard, i erased my data from backup disk as well.

On the 4th day, I rebooted my mbp and when i logged in back, the screen was blank with just the wallpaper and it took forever to load after that screen. I hard rebooted the system and logged in with other administrator account. Thats when I realised that my /Users/<username> doesn't have anything in it and completely erased off. But I still have the .<username> folder with sparsebundle in /Users/ which is the size of 56GB.

Can anyone help me on how to get back my data from the sparsebundle?
I already tried moving this .<username> folder to a different location and removing and recreating the profile and overwritten the new .<username> file with the old 56GB one. But even this did nt help as it again wiped out all the folders in /Users/<username> profile.

How do I retrieve this data??

Your problem is you really don't understand how OS X really handles data. If you save any data you should save it to YOUR Home folder, preferentially your Documents folder (/YourHardDrive/Users/YourUserName/
Documents/).

The applications in iLife are intertwined with each other with a QuickTime technology. So the any messed up QuickTime plugin will cause problems. Leopard is being tripped up right now with any application with an Application Enhancer plugin. Also any older DivX Quicktime plugin will also trip up Leopard
.

So to make sure you have a working Leopard machine you can start with a clean slate since you have a backup. If I were you I would Erase and install then use the install Migration tool (that pops up) and only transfer User data. Once the install is done then install (don't use Software Update)the full 110MB 10.5.1 standalone update and install it. Then after the restart install the Software updates. Then install the iLife package. Then after that install the iLife Software Updates. After all that, access your data. Then after all that install applications one by one and make sure you use the latest versions.
