Ok so an update on this, the creation of the new datstore succeeded eventually after about an hour and a half. I then started to move some of my VM's to it, the first VM was 16gb and it took about an hour and a half to copy and then stopped with an error saying all the files could not be copied. Everytime i try and access the new datastore I get very long pauses (multiple minutes) before I can browse the datastore and file copies are taking forever. Is this a faulty disk or is expecting VMWARE to work with 2 SATA drives expecting too much.
In storage adapters I see 4 entries
The working disk is plugged into vmhba33:0:0
The disk causing me issues is plugged into vmhba1:0:0
vmhba34 and vmhba0 are both empty
This fits with the four SATA ports on the motherboard.
I don't know much about SATA I'm afraid, is the port I selected relevant and would using one of the other two make any difference?
Thanks for any help.
