    shared tab in explorer properties (Win xp)

    I am experimenting with TrueCrypt and seek confirmation about a sharing problem.
    The laptop is a 100GB hard drive.
    TrueCrypt has created a volume, part of my 100GB hard drive, and I have assigned to it the drive letter P:.
    I want to share this drive P: with the second computer (also WinXP) on my network.
    The tab for file sharing does not appear when I right-click drive P: and choose properties.
    I suspect that this is because my WinXP system is NFTS, and truCrypt sets up the drive as Fat32.
    Am I correct?

    XP can and does access FAT32 partitions with no problem. What does disk management show?

    This is a virtual volume, right? It looks to me like the limitation may have been "imposed" by this TrueCrypt, which I know nothing about. I notice that even when I mount an image with TrueImage backup program, that (virtual) drive letter can be shared while it's alive, so it doesn't look an XP or FAT32 problem to me. You might want to start your search at the TrueCrypt end.

    J> What does disk management show?
    Thanks for the response. As you will have gathered I had to serach the lounge to find about about "disk management", but I'm back now (grin!)
    Disk Management shows that I have but two volumes - the CD drive having no CD present.
    None of my SUBSTituted drives show up; I use SUBST to assign drive letters to folders for active tasks/clients. Hence "F" and "I" and "T" and "W" etc.

    I'm not sure what i should be doing/looking at in disk management.

    Re: shared tab in explorer properties (Win xp)

    From TrueCrypt - Free Open-Source On-The-Fly Disk Encryption Software for Windows Vista/XP/2000 and Linux - FAQ:

    Q: It is possible to mount a single TrueCrypt volume simultaneously from multiple operating systems (for example, a volume shared over network)?

    A: Yes, but the volume must be mounted in read-only mode under each of the systems (see the section Mount Options in the documentation). Note that this requirement applies to unencrypted volumes as well. One of the reasons is, for example, the fact that data read from a conventional file system under one OS while the file system is being modified by another OS might be inconsistent (which could result in data corruption).

    Try also TrueCrypt Forums :: how would i share files (on encrypted drive) over a network?
    Any help?

    Wot! Do some research? (grin)

    The Truecrypt forum reveals such cryptic commands as
    "net /y stop lanmanserver
    net start browser"
    and
    "D:WINXPsystem32net.exe share J=J: "

    Substituting "P" for "J" in the above command revealed that I could see drive P: from the other (networked) computer.
    Thanks.

    I will continue with my Backup mechanism, but am still puzzled as to why I don't see the Shared Tab in dialogue boxes.

    Re: shared tab in explorer properties (Win xp)

    Well, disk management shows that you really have only one partition on the drive. As BigAl surmised, the TrueCrypt software created a virtual partition. Therefore, the partition is under its control not XP's control. The TrueCrypt software defines what is allowed including the available tabs in Windows Explorer.

    I have just created a TrueCrypt volume, mounted it as drive Y: and I have a sharing tab, just like any other disk drive. (I checked this with both NTFS and FAT volumes).

    >A: Yes, but the volume must be mounted in read-only mode under each of the systems (
    This puzzled me for a minute, but then it made sense.
    This is the case when I would be running TrueCrypt on both machines, and would want to TrueCrypt-Open/Mount the volume simultaneously.
    In my case I'm running TrueCrypt only on the Laptop, and want (and can) open up the volume and share it as P, and gain access to its folders and files from the second computer.
    FWIW I've just done that.

    My situation arises when I create a 5GB volume and have problems backing it up with XCopy; sharing the mounted volume allows XCopy to copy files selectively.

    So what is so special about your drives (sulks)?

    Re: shared tab in explorer properties (Win xp)

    Ah!
    More problems with sharing a TrueCrypt volume after a re-install of WinXp.
    I seem to have overcome the problem of sharing by following the instructions on page 62 of the TrueCrypt User Guide.pdf:

    PROBLEM:
    When accessing a file-hosted container shared over network, “insufficient
    reported.
    PROBABLE CAUSE:
    IRPStackSize in the Windows registry may have been set to a too small
    POSSIBLE SOLUTION:
    Locate the IRPStackSize key in the Windows registry and set it to a
    system. If the key does not exist in your Windows registry, create it
    HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesL anmanServer
    and set its value to 16 or higher. Then restart the system. For more
    http://support.microsoft.com/default.aspx?...kb;en-us;285089

    I can now see all drives that I want/ought to see on each of the three networked computers.
    Tomorrow I'll check my BATch files to see that they are correctly copying archivable files.
