Sorry if this might sound stupid....
 
I was trying to use Ghost to create an image of my new notebook onto a 8GB SDHC card.  
 
Ghost created a boot drive automatically onto the SD card with PC-DOS and the ghost.exe.
 
However I realise that the drive became only 2GB (1.9GB) and there is no way for me to activate the remaining 5gb even in Windows.
 
I used windows XP disk management but cannot "unpartition" the 2GB or allocate the 5GB..
 
Is there a way to revert back to an 8GB disk ?
 
Please advise...
 
Thanks

Usually you should use the manufacturer-tool to format these cards. I heard of people losing their card after they formated with windows.

You might try using SeaTools (from Seagate).  There's an advanced feature to set the capacity of a drive-- you likely can reset the capacity back to the original 8GB.
