Corrupt OS X Partition Again

[MacSac]

Hello

 

I have a Samsung NP130 netbook, used to dual boot Windows XP and OS X. I've installed iDeneb 10.5.7 successfully on it twice in the last three weeks. The first installation lasted a few days before the OS X partition became corrupt.

 

The second installation lasted two weeks before the OS X partition became corrupt.

 

I have always run the OS X instllation in conjunction with Windows XP which came pre-installed on the netbook.

 

I have MacDrive 7 installed on Windows XP and have a strong feeling that this is the cause of the problem. The first time OS X became corrupt was when I plugged in an unreadable flash disk, restarted into Windows, ejected the flash disk and booted into OS X again (eternal blue screen with 'loading wheel spinning).

 

The second time my OS X partition became corrupt was when I copied photos from my camera to my Windows partition in Widnows XP, unplugged it and rebooted into OS X (Again eternal blue screen).

 

The Chameleon bootloader still pops up at startup and Windows continues to work fine.

 

What is the problem? I have read of other people having the same issue but with Macbooks elsewhere on the net. I think it is Macdrive, but just want to be sure. Is there any way I can keep Macdrive installed and disable HFS writing and still be safe? If it is Macdrive, what exactly causes OS X to become unbootable?

 

Also, under Windows XP my OS X partition is still detected but reads as having 47.5GB free (when it had 1GB free before becoming corrupted), and can't be accessed (error message).

 

Thanks very much
