Can't create partition
Posted: 01 May 2016, 08:44
I have a 2TB external disk that suddenly lost its partition information (and I'm invited to repartition/format from Windows 10). Running Testdisk "finds" some linux partitions (no idea why, since they were never there), but also sees this
NTFS at 243200/235/43
filesystem size 3907022848
sectors_per_cluster 8
mft_lcn 786432
mftmirr_lcn 2
clusters_per_mft_record -10
clusters_per_index_record 1
HPFS - NTFS 0 0 1 243200 235 43 3907022848
NTFS found using backup sector, blocksize=4096, 2000 GB / 1863 GiB
Partition not added.
So I try to add the partition manually

when I click on Done, I get nothing (see below)... What is going on? What am I missing? Thanks in advance!
