Hello, I'm transferring information off a Powerbook G4 with Leopard onto a MBP with Lion. For key projects, I like to create DMG's and than work within the PW protected DMG so that the whole project is pw protected & I don't have to worry about individual assigning a pw to each excel file (or others). The sizes of the DMG vary, but are usually 5-10gigs. I have 2 questions and am wondering what you guys thought the problem might be? 1.) When I transferred the 10 gig DMG from Leopard to Lion, the size magically increases to 10.8 gigs, what gives? In Leopard it shows the size as 10.0 gigs and lion tacks on a extra 800mb, anyone know why this might be happening? 2.) Also, as I said, the DMG's are pw protected. They open fine in the computer with leopard, but when I transferred them to lion, I keep getting authentication fail errors. It is not accepting my pw. I am transferring the DMG by use of a NTFS formatted Ext. HD (i have the beta macfuse & free NTFS-3G Driver installed in Lion). Likewise, when I try to open up the DMG from the ext. hdd, it also says "authentication error." When I transfer other files via this ext. HD (though they are not pw protected files, such as Word, pictures, etc.) it works fine. Anyone have any thoughts? Thanks.
