Freeware to inspect hard drive

Discussion in 'Storage Devices' started by Daniel Prince, May 20, 2012.

  1. I need a good Windows XP freeware program to inspect my 2tb SATA
    hard drive. Computer Management says that it has a 232.88 gb
    partition which is healthy and active but when I try to explore it
    Windows says that it is not formatted. I think the partition has
    files on it from my Tivx DVR. I would like to save those files if I
    can. Thank you in advance for all replies.

    When I am in the kitchen, I often kick one of my cat's balls.
    After I kick it, he will sometimes play with it for a few
    seconds to several minutes. His favorite are the ones that
    rattle. He'll play with any ball that makes noise.

    Its generally simplest to use a linux live CD to look at the drive.

    A lot of DVRs use a proprietary file system (or embedded Linux), and
    the data is often encrypted, for DRM reasons.

    Could we see the partition table and boot sector(s) with Microsoft's
    Sector Inspector?
    http://www.users.on.net/~fzabkar/SecInspect.zip

    Extract the above archive to the one folder and execute the SIrun.bat
    file. The procedure will generate a report file named SIout.txt.

    When a cat sits in a human's lap both the human and the cat are usually
    happy. The human is happy because he thinks the cat is sitting on him/her
    because it loves her/him. The cat is happy because it thinks that by sitting
    on the human it is dominant over the human.

    The drive is an Advanced Format model with a physical sector size of
    4KB. Your partition table has a single entry with a size of 488378646
    LBAs.

    Windows XP is assuming that the sector size is 512 bytes, in which
    case it thinks that the size of the volume is ...

    488378646 x 512 = 250 049 866 752 bytes = 232.9 GiB

    The actual size is ...

    488378646 x 512 = 2 000 398 934 016 bytes

    Furthermore, this file system is unusual in that there is an "NTFS"
    signature, yet the partition ID is FAT16 (0x04).

    Partition types: List of partition identifiers for PCs:
    http://www.win.tue.nl/~aeb/partitions/partition_types-1.html

    Even more unusual is the fact that the partition table points to LBA 0
    as the starting sector for the logical volume, ie the boot sector and
    MBR are one and the same. This is the reason that Sector Inspector's
    report duplicates this sector. The usual regime places the boot sector
    at LBA 63 or LBA 2048.

    I recommend the following resource for analysing boot sectors and
    MBRs:

    NTFS Volume Boot Record Of Win2K & Win XP:
    http://thestarman.pcministry.com/asm/mbr/NTFSBR.htm

    The section from 0x000 to 0x053 corresponds to a valid NTFS volume.

    I believe that you may be able to access your data if you edit the
    partition table (offset 0x1C2) so that the partition ID byte is 07
    (=NTFS) rather than 04. Then install the drive in a Vista or Windows 7
    system, or install it in a USB enclosure that uses 4KB LBAs rather
    than 512-bytes, in which case Win XP will be able to access it.
    Western Digital and Seagate 3TB external drives do it this way in
    order to maintain compatibility with Win XP.

    You could also trying mounting the drive using Linux or DMDE (after
    editing the partition ID).

    DM Disk Editor and Data Recovery (Free Edition):
    http://softdm.com/download.html

    That said, we still don't know if the data are encrypted.

    I have this:

    USB docking station. How can I tell if it 4KB LBAs?

    I have decided to buy a second USB docking station. Do you know of
    one that uses 4KB LBAs? I want one with two SATA slots.

    I was using this drive with Windows XP Home SP3. It worked
    correctly but was rather slow because it is a Western Digital Green
    drive. I bought a Tivx DVR so I decided to buy a Hitachi 7200 rpm
    for my PC and use the Western Digital Green drive in the DVR.

    After I installed the Hitachi in my PC, my brother said that he
    should reformat the WD in his Windows 7 PC. (He had also bought a
    Tivx and had already set it up.)

    After my brother formatted the drive, it seemed to work correctly.
    Later I discovered that after the drive reached just 87 percent
    free, it stopped recording but it did not give an error message. The
    DVR turned on and the display said that it was recording. (It was
    pretending to record.)

    For several weeks, I could get it to actually record programs by
    keeping the drive at more than 87 percent free. Recently, all my
    programs disappeared and the check disk function of the Tivx said
    that the drive had failed.

    I bought a Samsung 2tb 5400 drive. My brother formatted it on his
    Windows 7 PC. It recorded just ONE HOUR before it started
    pretending to record. We tried the Samsung in his Tivx DVR and it
    did the same thing.

    I tried to reformat the Samsung in my SATA drive dock. I got an
    error message saying that the format had failed. When I did a quick
    format, I got the message right a way. When I did a full format, it
    took about 30 hours. After it got to 99 percent finished, I got the
    format had failed message again.

    I have not yet run Microsoft's Sector Inspector on the Samsung
    because my brother is doing a full format with the drive installed
    in his Windows 7 computer.

    I think my brother's Tivx is running correctly. Do you have any
    idea why my WD drive got formatted in such a weird way? If the
    format my brother is doing on the Samsung fails, do you have any
    suggestions as to how we can format the drive?

    I'm sorry, I can't answer either question.

    As for your Tivx, do you have a link to a user manual?

    Is the Tivx capable of preparing a blank drive using its own built-in
    functions? Does it have a USB interface that allows a host OS to
    prepare the drive in-situ?

    Sector 0 appears to be a Win 7 boot sector:
    http://thestarman.pcministry.com/asm/mbr/W7VBR.htm

    The tail end has been replaced with a FAT16 partition table, probably
    by the Tivx box.

    Why are you using Win 7 to format the drives externally?

    Your current "87%" problem is sounding like there is some confusion
    regarding sector sizes. If the figure is in fact 87.5%, then this
    would suggest that only 1/8th of the drive is accessible.

    4096 = 512 x 8 ...

    ISTM that another Sector Inspector report may clear this up.

    I used the disk editor and changed the 04 to 07. The report from
    Microsoft's Sector Inspector is the same except for these added
    lines:


    Partition #1 NTFS backup boot sector at LBN 488378645.

    ClustersPerFRS : 1
    Clust/IndxAllocBuf : 1
    NumberSectors : 488378645 ( 1.90773e+006 MB )

    Mft2StartLcn : 2
    SerialNumber : 4785211336117997601
    Checksum : 0 (0x0)

    Disk Management and Aomei Partition Assistant 4.0
    http://www.extend-partition.com/ both say that the drive has a
    232.88 gig unformatted partition (primary and active) and a 1630.14
    gig unallocated space (logical with a status of none). This is when
    it is connected to my SATA dock. I have not yet connected it to a
    Windows 7 system.

    Your new information, namely that you formatted the drive in your PC
    using Windows 7, complicates things immensely. I think it would be
    safest to return the partition ID byte to its original state, ie 0x04,
    otherwise the Tivx box (whatever it is) may not like it. Something
    created the partition table, and it wasn't Win 7. Perhaps you should
    reconfigure the Tivx box using a zero-filled HDD, and then allow the
    Tivx to prepare it. That will eliminate the Win7 obfuscation.

    As for the latest Sector Inspector report, this time the NTFS
    information is being correctly interpreted, but the question now is,
    is this information used by the Tivx box, or is it a remnant from Win
    7's formatting?

    A user manual might help, otherwise there is not enough information,
    at least not for me.

    After I changed the 04 to 07 I put the drive back into the TVIX (I
    had it wrong before when I called it "Tvix") unit and the recordings
    that had disappeared were back.

    >A user manual might help, otherwise there is not enough information,
    >at least not for me.


    I found the user's manual. The manual says that the TVIX will
    automatically format a drive but I could not get it to do that. My
    brother says that he had trouble getting his TVIX to format his
    drive but that it finally did it after he went to the RECORD LIST
    menu.

    That's good to hear. But that begs the question, who or what modified
    the partition table?

    Page 71 states that you can prepare and format the external drive via
    USB just like any USB mass storage device. You can also transfer
    recorded programs to and from the TVIX.

    Elsewhere it states that "the first partition of the internal hard
    disk must use the NTFS format. FAT32 format can cause an error
    message."

    Also, "you cannot use the DTV time-shifting on FAT32 partitions, so we
    recommend that you format your SATA HDD to NTFS."
