First need to enable SSH access fro ESXI host via ESXI firewall
Once you done that connect to ESXI via putty and run this command
ls -lha /vmfs/devices/disks
This will list all the all the disks in datastore and make sure to mark down the datastore ID. Its is something like naa.1234abcd1234XXXXX. Be careful not to choose wrong data drive!!!
Then run this command
partedUtil setptbl /vmfs/devices/disks/ < ID from the disk that you copied above> msdos
After that you will be able to create data store without an issue.
