Thread: Paritioner messages about hard drives

  1. #1

    Default Paritioner messages about hard drives

    When I run Partitioner I get the message:

    "The partitioning on /dev./sdb is not readable by the partitioning tool 'parted', which is used to change the partition table.

    You can use partitions on /dev/sdb as they are. You can format them and assign mount points to them, but you cannot add, edit, resize, or remove partitions from that disk with this tool"

    The same message comes out for /dev/sdc, but evidently /dev/sda is fine with 'parted'.

    I have Minitools, EaseUS, and Acronis Diskl Director 11, all of which, running under Windows or booting up standalone, can read all the partitions on my hard disks. Furthermore when I use Clonezilla if can also find all the partitions on all my hard disks. Finall;y when 'parted' does come up it shows all the partitons on all my hard drives.

    Does anyone know why Linuix 'parted' cannot read the partitioning on the last two of my hard disks. The hard disks are all 2 TB disks, formatted as MBR, and divided up into various partitions for Linix and Windows.

Furthermore when I use Clonezilla if can also find all the partitions on all my hard disks. Finally when 'parted' does come up it shows all the partitions on all my hard drives.

    Does anyone know why Linux 'parted' cannot read the partitioning on the last two of my hard disks. The hard disks are all 2 TB disks, formatted as MBR, and divided up into various partitions for Linux and Windows.
    So I can't say why but there must be some sort of data in the partition table that is not standard to parted. I can say the first time I saw this on a drive that was working, I removed all of the partitions with another tool and reloaded openSUSE and did not see this issue come up again. I also have Acronis and it is possible it did something that the openSUSE Partitioner did not like. In general, I have decided to keep Windows on one hard disk and openSUSE on another hard disk and I use Windows for NTFS partitions and openSUSE Partitioner for all things Linux, and this has avoided such messages. As long as all is working, you can keep on trucking, but the day you get tired of the message, you will need to take a similar action as I did. I must also add that on a different computer, I got this message from a SSD, formatted with openSUSE. Later, that SSD disk just died and was even replaced under warranty. It was kind of strange to have this (SSD fail and a Partitioner error message before it failed) happen at all.

    Let us try using parted instead:

    Code:
    sudo parted -l
    When you post the results here, use the Advanced Message Editor, highlight the new text and press the Code # option so that it looks like the command above, only larger.

    I do not know why it thinks that the drive(s) contain a GPT signature. I may have once had them as GPT and then converted them to MBR, but surely that would have removed any GPT signatures.

    Yes, I regularly get that message.

    I'm pretty sure that it is because I am installing from a USB, and "/dev/sdb" is that install USB. It uses a hybrid format so that the iso can be booted when written to a CD/DVD or to a USB. And "parted" does not seem to like that hybrid format.

    If I wanted to install to that USB, I would write a block of binary zero over the MBR, then repartition with "fdisk" before starting.

    My hard disks are not USBs. I have read about "hybrid" formats but I know I have a MBR hard drive and I am pretty disappointed that a core Linux program like 'parted' does not recognize it as such. All the other partitioning programs I use, largely Windows based, clearly recognize my hard drives as MBR. I believe Linux 'parted' needs to be updated to correctly understand MBR and GPT drives. Its lack in correctly identifying the difference has already affected me on some Linux distro installations and, in one case, wiped out my hard disk's MBR partition table. This is not good for Linux distros, to say the least.

    No, both fdisk and parted say that you have a GPT table. Windows partitioning software has been
    known for ages to interpret things differently than their Linux counterparts.

    Both fdisk and parted are right. My brother in law saw exactly this on a 1TB disk he had used and transformed through windows, fdisk and parted kept complaining. After he "dd"-ed the entire disk to zeros, the problem was gone. But then again, he only had stored about 120GBs on the disk, so backup was easy and quite fast.
