    So none of you can come up with and answer? Come on people. Maximum number of partitions on a hard drive. easy question.

    "The EFI specification mandates that a GUID Partition Table (GPT), which all modern operating systems support, is capable of containing a maximum of 128 partitions on any size hard disk. GPT is also required to boot from hard disk drives larger than 2 TB.

    TB."

    That's not a limit. The GPT can be any size from 4 partitions and up. To be compatible with EFI, it needs to accommodate _at_least_ 128 partitions.

    I just fitted a 6TB drive today and I am sure fdisk suggested partitions 1
    - 128 and it insisted on GPT

    https://en.wikipedia.org/wiki/GUID_Partition_Table#Partition_table_header_.28LBA_1.29

    «The partition table header defines the usable blocks on the disk. It
    also defines the number and size of the partition entries that make up
    the partition table. The EFI stipulates a minimum of 16,384 bytes be
    reserved for the partition table array, so there are 128 partition
    entries reserved, each 128 bytes long.»

    Notice the wording "minimum". There can be implementations using bigger
    sizes, thus.

    I just fitted a 6TB drive today and I am sure fdisk suggested partitions 1
    - 128 and it insisted on GPT

    No, not that easy. Traditional or new (GPT)? Version of driver? Because traditional partitions with the old scsi drivers was limited to 15
    partitions (numbered 1 to 15). And Haines Brown is using traditional
    partitions (he has one primary, then logicals from number five upwards,
    thus there must be one extended. Still, his setup is within that limit.

    With the current driver, however, there is no limit on the number of traditional partitions.
