• Reading an old HDD

    From Will Mengarini@21:1/5 to All on Fri Oct 4 05:00:01 2024
    I have a freshly installed Debian stable and I'm trying to read an
    HDD from a previous machine. I put it into a disk enclosure that
    connects to the new machine by USB and powered everything up, but the
    stable Debian doesn't see the new disk that is connected by USB. Is
    there some driver or package that I need to install to make this work?

    which file system is the old hdd formated in ntfs?

    if so run in terminal

    sudo apt install ntfs-3g

    or use gparted to see the file system of the hdd
    sudo apt install gparted

    The old HDD is mostly ext3; there was also an
    ext2 boot partition, and a swap partition. But
    the new Debian shows nothing new in `df`. Is
    there some other command I should use to probe for
    whether Debian knows there's a HDD connected by USB?

    "df" will ignore filesystems until they are mounted.

    - Do you see anything in "blkid" when the USB enclosure is attached?

    - Do you see anything in "journalctl -f" when you plug in the USB enclosure?

    - Do you have a desktop file manager (e.g. Thunar in XFCE), and if so,
    does it show any unmounted partitions? As an ordinary user, you might
    not have permission to mount or access them, but it would be good to
    know if they are there.

    What do you mean by "doesn't see"? Is the USB device visible? Disk device?
    Partition table?

    Take a look at /dev/disk/… where the names of the next level
    of directories are self-explanatory. The files themselves
    are all symlinks pointing to the kernel's device names.

    Also /run/udev/data/b… where spinning rust disks are b8:N,
    and N is a power of two for a disk, then N+1, N+2 etc for
    the partitions. SSDs will be some other number like, say,
    b259:0. The file contents are what udev has discovered.

    Cheers,
    David.

    I see lots of directories referring to my SSD, but nothing else.

    All I see are b259 and b7. There is no b8. This
    does not change when I plug in the enclosure.

    Now I realize that there may be an error LED blinking on the HDD. It
    is concealed by the enclosure so I had not seen it before. I think
    this hard drive is probably bad. It may have been damaged when the
    motherboard to which it was attached was damaged by a power surge from
    hell, or it may be connected improperly to the enclosure (although
    that seems unlikely since there is only one way to connect it).

    Or the enclosure may be bad; I only bought one so I have no way
    to test that hypothesis. I don't see a brand name anywhere on
    the enclosure. I was surprised at how short both the power
    and data cables are. The whole thing does seem rather cheap.

    You say, it is connected by USB. You then should see the device with the command

    lsusb

    when the usb-connector is plugged in. However, I have to precice it: You see the controller of the case, you put your HDD in, not the hdd itself!

    But, if you can see it, first step is done.

    For further examinations I suggest, to do the following commmand as root

    tail -f /var/log/syslog

    in console and then watch its output by pluggin in and pluggin off the usb- case with the built in hdd.

    It should be detected.

    If you still can not see the reason, I suggest, for copying the old date using a livefile system like Knoppix, Debian-Live, Kali-Linux, TRK or whatever.

    With those you might also be able, to check, if you can mount the usb-device
    at all. If this fails, it looks just like your usb-case is incompatrible, try another one if available. There are some USB3 cases, which can not well switch to USB2-mode.

    I suppose, it is an IDE-drive, and your controller of the mainboard does have no more IDE-port, does it?

    For more hints, i need more information., but that is, what comes in my mind
    at the moment. Hope, it helps though.

    Best regards and good luck!

    That looks to be a USB problem. The log should show first a USB
    connection, then the recognition of a mass storage device, then a
    device designation. If none of that happens, a hardware USB problem is suggested. Plug in a random USB stick to see what should happen.

    Can you see the enclosure in the output of `lsusb`?
    what is the output of `lsblk`?
    If there is a block device it should shown, with there partitions even unmounted.

    What's the filesystem you expose to see?
    Is there a RAID or LVM on that device, then you should start this first.

    The HDD may not be able to draw enough power. Plain USB A ports can only deliver 2.5W (500mA at 5V). You mentioned that the enclosure also has a
    power cable. Is this another USB cable? Is it plugged into a USB port or
    a power adapter? Many USB power adapters can deliver more current.

    Power is coming from a transformer. The box says that

    That may not have been an error LED; it's an LED on
    the PCB of the enclosure, and it may be intended
    to blink red whenever the disk is being accessed.

    What is the model of the HDD? What is its documented peak power draw?

    The drive is a Seagate 3.5 inch 500 GB drive. It's now screwed into
    the enclosure, so pulling it out to look for a model number would be
    a little risky because the thing could be dropped.

    The smallest 3.5" HDD (3 TB) for which I found official Seagate
    documentation said that it used 8 watts while operating.

    https://storedbits.com says a 7200 RPM hard drive would normally consume
    20-25W for 5-10 seconds during startup. It will then idle at around
    6-8 watts. The average power consumption during read/write tasks
    will be around 8-12 watts, and the maximum can go up to 16 watts.

    I would be surprised if the transformer for the enclosure
    did not deliver sufficient power for the type of
    drive that the enclosure is intended to enclose.

    I have tried multiple USB jacks on the computer, of course.

    Do you start "journalctl -f" as root (eg sudo)? It is rather
    strange that nothing is logged at all. I would expect
    at least some errors. It may be some issue with cables.

    Yes, I am doing that as root. It has never shown any output for
    the drive and enclosure in question, but it responds immediately
    when I plug in a flash drive that has Debian netinst on it.

    Have you tried other USB ports? USB3/USB2,
    some ports may provide higher current.

    Yes, several.

    Save output of of the following command to files when the enclosure is disconnected and connected and compare results

    lsusb -vt | tee /tmp/disconnected.txt
    lsusb -vt | tee /tmp/port1.txt

    There is no difference.

    Try to connect the enclosure without the disk. It may appear
    in lsusb output and may generate some journalctl logs.

    That's a clever idea, but it will be a while before I
    can carefully unscrew the disk from the enclosure to try
    it. First I need to try to restore from older backups.

    Power is coming from a transformer. The box says that the transformer delivers five watts/12 watts [I meant volts, of course] of power.

    When I unplugged the transformer just now to store it, I
    discovered that on the back it is labeled to output 12 volts
    and 2.0 amps. That is 24 watts, which might not be enough to
    spin up some hard drives. I'm not sure; it seems borderline.

    I have no idea what steps you may try without disassembling the enclosure. Perhaps the issue is either data or power connectors inside.

    HDD should generate specific noise when spinning up, then there should be something like clanks due to heads unloading/loading. Do you hear it?

    No, I heard nothing, but I might not have heard the spin-up
    noise because the enclosure needed to be placed behind the
    desktop tower because its cables were so short. As for the noise
    of the heads, there was none, probably because the operating
    system never saw the disk so never tried to read the disk.

    However, I just achieved a breakthrough by discovering an
    astonishing cause to the problem. I will post this as a
    reply (labeled "maybe solved") to to my original post.

    For 3,5" HDD you need an usb-case with extra power. The standard usb power is not enough for this needed power.


    Most usp ports deliver about 50-70mA at 5V, so you must use a case with an external power supply.

    This is also needed for eSATA ports.

    * Will Mengarini <seldon@eskimo.com> [24-10/03=Thu 19:57 -0700]:
    I have a freshly installed Debian stable and I'm trying to read an
    HDD from a previous machine. I put it into a disk enclosure that
    connects to the new machine by USB and powered everything up, but the
    stable Debian doesn't see the new disk that is connected by USB.

    There were several suggestions that the enclosure may not have
    been receiving enough power, and I think that it was not, although
    I didn't realize this until I had put the enclosure away and
    started to attempt restoring from an old backup on an external HDD.

    Initially that HDD (my only recent backup) could not be mounted
    because of continuous errors. However, prompted by the discussions in
    here about power, I tried a different power strip, and noticed that
    on that power strip there was a transformer for a pair of speakers
    that had worked correctly until the machine I was backing up from
    had crashed, but now did not seem to be working correctly because
    their power LED was always off. That seemed strange, so I removed
    the transformer for that pair of speakers since they didn't work
    anyway, and suddenly the hard disk drive from which I was restoring
    was able to be mounted. I am using rsync to restore from it now.

    The power strips were chained, so it seems plausible that a failed
    pair of speakers connected to one power strip was drawing enough power
    although doing nothing that it was preventing the hard disk drive on a different power strip from receiving enough power to spin up properly.
    Once the transformer for the speakers was unplugged, the hard disk
    drive was able to spin up and I was able to restore from backups.

    The reason this is only "maybe" solved is that I haven't yet gone
    back to the hard disk enclosure that was the original subject of
    this thread. Instead I'm restoring from a different external hard
    disk drive which also was failing until the transformer for the
    speakers was removed. I conjecture that eventually I will be able
    to read from the hard disk drive enclosure containing the latest
    data, but first I will finish my current restoration from backup.

    This is a wild war story. I would not have expected a failing pair
    of speakers to be able to draw enough power to prevent a disk
    drive on a chained power strip from receiving enough power. It
    may actually be the case that what really mattered was that those
    speakers were plugged in to the rear panel of the desktop computer
    that I was setting up, and perhaps they were drawing too much power
    from there. I cannot think of an easy way to test that hypothesis
    without endangering this hardware, which I do not want to do.

    A hmm-worthy observation is that in order to get this new computer to
    work I needed to plug it into an old LCD monitor (Viewsonic VX2025wm)
    that has its own built-in speakers. I wonder whether there is some
    operating system bug that can cause trouble when external speakers are
    plugged into a computer that also has speakers built into the monitor.

    Many thanks to everybody who participated
    in this thread and gave me suggestions.

    https://storedbits.com says a 7200 RPM hard drive would normally consume
    20-25W for 5-10 seconds during startup. It will then idle at around
    6-8 watts. The average power consumption during read/write tasks
    will be around 8-12 watts, and the maximum can go up to 16 watts.

    I would be surprised if the transformer for the enclosure
    did not deliver sufficient power for the type of
    drive that the enclosure is intended to enclose.

    For a 3,5" HDD you need a USB case with extra power. The
    standard USB power is not enough for this needed power.

    Most USB ports deliver about 50-70mA at 5V, so you
    must use a case with an external power supply.

    This is also needed for eSATA ports.

    This case does have an external power supply.

    However, I think there *was* a problem related to inadequate power,
    and I just posted a reply to my original post detailing how I
    think I have solved the problem. Thank you for all of your help.

    When I unplugged the transformer just now to store it, I
    discovered that on the back it is labeled to output 12 volts
    and 2.0 amps. That is 24 watts, which might not be enough to
    spin up some hard drives. I'm not sure; it seems borderline.

    It should be OK and in any case it should be easy to diagnose simply by listening to the drive.

    As for the noise
    of the heads, there was none, probably because the operating
    system never saw the disk so never tried to read the disk.

    There is always head movement when a drive first spins up. Part of
    shutting a drive down is moving the heads to a safe zone such that if
    any vibration causes the heads to hit the platter it won't damage any
    surface with data on it. Part of spinning up is moving the heads back
    to the middle of the drive so that the first access will be quicker.

    However, head movement isn't always audible. 3½" and 5¼" drives aren't usually audible, although I've had a few very noisy 5¼ drives. And of
    course SSDs are utterly silent.

    I wonder how ancient drives you are using? Have there even been any
    mainstream 5¼ inch form factor HDDs manufactured since the Quantum
    Bigfoot  in the 1990s? I remember those drives being quite loud indeed.

    This is a 3.5 inch drive from a desktop tower that was built in 2007.
