Aw: Re: Re: grub does not detect partition 5 on new USB-WD My Passport 1TB

[Peter Littmann]

I created some partions and checked them in grub console, now it seems grub can detect the right device size but can not handle partitions on the other side of the 128GB border.

 

peter@mediondt:~$ LANG=C sudo fdisk -l /dev/sdb
Disk /dev/sdb: 931.5 GiB, 1000170586112 bytes, 1953458176 sectors
Disk model: My Passport 25E1
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x43bee096

Device     Boot     Start        End    Sectors   Size Id Type
/dev/sdb1  *         2048   78125055   78123008  37.3G 83 Linux
/dev/sdb2        78125056   87889919    9764864   4.7G 82 Linux swap / Solaris
/dev/sdb3        87889920  169809919   81920000  39.1G 83 Linux
/dev/sdb4       169809920 1953458175 1783648256 850.5G  5 Extended
/dev/sdb5       169811968  251731967   81920000  39.1G 83 Linux
/dev/sdb6       251734016  333654015   81920000  39.1G 83 Linux
/dev/sdb7       333656064  415576063   81920000  39.1G 83 Linux

 

The Linux partitions from sdb1 up to sdb6 can be listed in the grub console, sdb7 not.

 

I would be thankfull for any further ideas.

 

Best regards,

Peter Littmann
