    Good Day.

    I am using a Macbook Pro, Snow Leopard.
    I have some external hard-drives that i encrypt with Truecrypt 6.3.
    Creating and mounting the encrypted volumes work fine, the mounted volume pops up as a read/write ready volume.

    This is the first time I use the Mac OS Extended (Journaled) file system and hence the questions.
    I have good experience with backup using explorer and teracopy in the NTFS environment.

    I am used to double check if a copy have been successful by getting the information and seeing that the total file-size, number of folders and files match up to the original folder.

    Three Questions:
    If i copy 1TB of assorted media, will the exact same number of files/bytes/folders be represented in destiny folder when I see the information?
    Is there any database/thumbnail files generated and stored any place on the external HDD?
    Will the file system change the "Last edited" date on the folders when copied from a NTFS disk?

    The yet-to-decide-quality-of copy-handler I am currently using is MiniCopier. If anyone has recommendations on alternatives, I am pleased to hear about them:)

    God dag!

    Probably not.

    Yes. Mac OS X generates hidden (to you) files called .DS_Store containing directory view info and such. It also saves some data in ~/Library/Preferences/com.apple.finder.plist.

    I'm really not sure. Probably, yes.

    You know you'll need to have MacFUSE and NTFS-3G (or other third-party drivers) installed for read/write access to NTFS, yeah?

    Carbon Copy Cloner is a good bet.

    God Dag^^ Har du kjennskap til Noreg/Norsk?

    Thank you for your replies, it has answered all my questions.

    It looks like I will not be using my Mac as primary backup-manager.

    The file number counts as the same, but I figured a file with some bytes was stored in each folder since the "last editet" tag on the folders changed from their original date to "Today" often time. When I copy a folder from a destination to another, each folder gain some extra bytes. Your post confirmed it, and explained it:)

    The attributes on a given file is mostly the same when i Move them around, with the exeption to "Folder last editet", but that is not that important as long as the files stay intact.

    I just tested, and found out that MiniCopier removed the original data!
    I do not Reccomend MiniCopier for handling files. That is a grievous error.

    I have downloaded Carbon Copy Cloner instead, thank you for the advise:)

    Ja, jeg studerer norsk i universitetet nå. I'm only in my first year, though.

    Fortreffelig.

    Not often you see people studying Norwegian from other countries. You will become one of only 5,000,000+ that can speak it:) Only some hundred thousand speak it outside Norway.

    I suppose you are coming to Norway. I am really curious to why learning the language if not.

    All of my grandparents emigrated from Norway to Canada as children. I haven't been yet, but I most certainly will. :)
