No problem, you just going to get 300G worth of capacity from that drive. I would make sure to check the part number of that drive to see if it’s supported by your Flare version.
 One of our Valut Drives failed.  It is a 300GB / 15krpm FC HD.  Supplier just sends a 450GB / 15krpm FC HD and asks us to replace the faulty one.  We just want to confirm that there will not be any problem if we replace the faulty one with the 450GB one.  Thanks
Can we replace a faulty Vault Drive (300GB) with a 450GB one ?
