Hello,
I have a datastore called "Secondary", this datastore was apparently extended over two different drives. Another person thought it would be a good idea to swap out the Raid Controller. They did that and then reconnected the old raid controller when nothing worked.
Anyway. Here we are. We have Disk Internals VMFS Recovery software but it seems to crash at 1TB transferred. Is there a way to rebuild the datastore without losing data and having ESXI see the datastore as it did before? Some information follows.
