    Hi,

    I am unable to mount a specific volume on a drive.  Disk1s1 mounts correctly, but disk1s3 does not.  I am using fuse-ext2 version 0.0.7.  Output from the cmd is as follows:

    macbook-2:~ david$ fuse-ext2 /dev/disk1s3 /Volumes/test1
    fuse-ext2: version:'0.0.7', fuse_version:'27'
    fuse-ext2: enter
    fuse-ext2: Error while trying to open /dev/disk1s3 (rc=2133571347)
    fuse-ext2: Probe failed

    Any ideas?  Thanks
    -david

    hi,

    errors number is 'bad magic number', can you send me the output file (disk1s3.header) of below command?

    # sudo dd if=/dev/disk1s3 of=./disk1s3.header bs=1024 count=2

    the 1080, and 1081 nth bytes should be 0x53 and 0xef, for a valid ext fs. or it should be as far as i know :) you can send me the file via email (alper.akcan dot gmail dot com), or if you do not want to send any data, you can check the offsets i mentioned to check if the magic is ok. you can use hexedit application to see the values for offsets - http://sourceforge.net/projects/hexedit

    if you formatted the filesystem, can you also send me the command you used, and the tool name and the version you used

    thanks,
    alper.

    hi…thanks for the help!  I emailed the header file to you.  Regarding the format, I had this drive in a D-Link DNS 323 NAS, I installed and formatted it as a single volume.  I accidentally pulled it out of the NAS, and now it does not recognize the drive anymore (it keeps asking me to format it again).  Seems to be common with this particular NAS.

    Thanks again

    hi,

    sorry but by looking the header you sent, i think this is not a valid ext formatted drive. can you mount it on a regular linux os?

    alper.

    I'm  having the same problem.  3 mount and 3 fail to mount.  here is what happens for the largest one:

    james-goudies-imac:~ jamesgoudie$ fuse-ext2 /dev/disk1s2 /Volumes/test1
    fuse-ext2: version:'0.0.7', fuse_version:'27'
    fuse-ext2: enter
    fuse-ext2: Error while trying to open /dev/disk1s2 (rc=2133571347)
    fuse-ext2: Probe failed

    the hd is from a lacie external drive that died due to a crappy controller board.  It just started ticking and wouldn't fire up.  but in the new enclosure the hd fires up and gets recognized, just not all volumes mount.

    disk1s8, disk1s9 and disk1s7 all mount.  but not disk1s2, disk1s5 or disk1s6.  disk1s2 is the largest in capacity at 319GB it says the format is fuse-ext2.  disk1s5 is linux swap at 131MB, and disk1s6 is a fuse-ext2 with a 8MB capacity.

    ANHANGUERA,

    I am also having trouble mounting a disk. I ran your diagnostic and got the following -

    MacBookPro-001B6394AF35-7:bin Don$ sudo dd if=/dev/disk1s3 of=./disk1s3.header bs=1024 count=2
    2+0 records in
    2+0 records out
    2048 bytes transferred in 0.000678 secs (3020371 bytes/sec)
    MacBookPro-001B6394AF35-7:bin Don$

    Here is the error message that I received -

    MacBookPro-001B6394AF35-7:bin Don$ sudo ./fuse-ext2 /dev/disk1s1 /volumes/journeyer/ -o force
    fuse-ext2: version:'0.0.7', fuse_version:'27'
    fuse-ext2: enter
    fuse-ext2: Error while trying to open /dev/disk1s1 (rc=2133571347)
    fuse-ext2: Probe failed
    MacBookPro-001B6394AF35-7:bin Don$ sudo ./fuse-ext2 /dev/disk1s1 /volumes/journeyer/ -o force
    fuse-ext2: version:'0.0.7', fuse_version:'27'
    fuse-ext2: enter
    fuse-ext2: Error while trying to open /dev/disk1s1 (rc=2133571347)
    fuse-ext2: Probe failed

    I am a newbie at this and don't really understand the commands although the concept seems pretty straight forward.

    Thanx,
    Don
