    Hello,

    My external hard-disk has been infected recently by some windows virus.
    Since that time I can't do any copy, move or delete on it!
    I can't even log to my data there as all directories on it changed to <name>.lnk

    EX:
    macs-MacBook-Pro:New Volume 1 mac$ rm Thunderbird.lnk
    override rwxr-xr-x mac/staff for Thunderbird.lnk? y
    rm: Thunderbird.lnk: Read-only file system

    Any idea how can I get my data?!
    I am just looking to get the most important ones then I will format the hard.

    Thanks.

    Is it formatted NTFS? (i.e. read-only by default under OS X.)

    Then, unless you use third-party software on your Mac, you wil only be able to read from it. This is why delete and move will not work. Copy should work if you copy from that HDD to your internal drive. If you try to copy to the external it will not work.

    I would suggest using Spotlight or other tools like DaisyDisk to find the files you want to save and copy them to your internal.

    So it is just because of the format and noting about changed permission coz of the virus.

    Thanks a lot for the info :)

    No viruses exist in the wild that can run on Mac OS X, and there never have been any, since it was released 10 years ago. The handful of trojans that exist can be easily avoided with some basic education, common sense and care in what software you install:


    NTFS (Windows NT File System)
    • Read/Write NTFS from native Windows.
    • Read only NTFS from native Mac OS X
      [*]To Read/Write/Format NTFS from Mac OS X: Install NTFS-3G for Mac OS X (free)
    • Some have reported problems using Tuxera (approx 33USD).
    • Native NTFS support can be enabled in Snow Leopard, but is not advisable, due to instability.
    • AirPort Extreme (802.11n) and Time Capsule do not support NTFS
    • Maximum file size: 16 TB
    • Maximum volume size: 256TB

    Yes, sure. I was just thinking that may the virus changed some permission which prevented me to do any operations on it, but apparently it is the normal case.
    I am a new MAC user, and just started discovering it. Plus I didn't see such thing on LINUX before.

    Thanks again for the information.

    One other behavior I don't understand.
    I started to move my important folder to my internal MAC hard, but once it finished the folder became invisible!
    Why that? and How can I make it appeared?

    The folder has a regular name without '.' or something at the begining!

    Hello,

    Does anyone have explanation for the invisible folder?

    Thanks.
