    hi,
    i have a harddrive with gpt partitions. on the 2nd partition i have to set two attributes with gdisk "63" and "0" (dont know the exactly name of them). After cloning the entire disk the attributes disappear.
    i am using clonezilla-live-20161024-yakkety-amd64.
    in the image directory there is a sdb-pt.sf file. it contains:

    label: gpt
label-id: B87C5FB4-DBF4-45DB-8BB8-20FC424C51D8
device: /dev/sdb
unit: sectors
first-lba: 34
last-lba: 1953525134

/dev/sdb1 : start=        2048, size=   215040000, type=0FC63DAF-8483-4772-8E79-3D69D8477DE4, uuid=7A6C96F2-B5CA-403D-BC19-6A8BC0D4FA2E, name="Linux filesystem"
/dev/sdb2 : start=   215042048, size=  1736435712, type=EBD0A0A2-B9E5-4433-87C0-68B6B72699C7, uuid=4AE9D4D0-486F-4D98-848C-893F9E1C6985, name="Microsoft basic data", attrs="RequiredPartiton GUID:63"
/dev/sdb3 : start=  1952526336, size=       20480, type=21686148-6449-6E6F-744E-656564454649, uuid=3C535383-91D1-4D10-926E-B79B3E7AEF4C

    what can i do?

    regards

    Running sfdisk --force /dev/sdb < /home/partimag/2016-11-08-arch-attrib2/sdb-pt.sf (from the log)
    simply does not has an effect on gpt attributes

    In that case, you should use gdisk to set the attribute again.
    Acutally from the manual gdisk you can find:
    Set attributes. GPT provides a 64-bit attributes field that can
    be used to set features for each partition. gdisk supports four
    attributes: system partition, read-only, hidden, and do not
    automount. You can set other attributes, but their numbers
    aren't translated into anything useful. In practice, most OSes
    seem to ignore these attributes.

    That's why sfdisk does not keep those info I believe. They are simply ignored by most of the OSes.

    Thanks for reply.
    setting gpt Attributes is not that unusual, i think.
    Maybe we should rename clonezilla to something like "Almostclonezilla"
