Thanks. We'll let you know when a new response is added.

This will all depend on your RAID card. Most RAID cards will allow you do use larger hard drives. It will simply use the first half of the 73 Gig drive leaving the other half of the drive free for other use later.

You won’t be able to tell the RAID controller to make the array larger.

    Certain RAID controllers (whether add-in cards or on-board silicon) do indeed allow you to resize the array, however it is not a neat process and there is the distinct possibility that, if allowed at all, the process will fail. As was our standard disclaimer when working in the Support division of a major storage adapter manufacturer, before you proceed, make sure you have a VALID, CONFIRMED BACKUP!!! There's nothing quite like the feeling you get in the pit of your stomach when you realize that the backup process you thought was humming along just fine, has produces a batch of blank or unreadable/unusable tapes when the inevitable emergency restore arises.... That having been said, there are two possible ways to expand or extend the array sizes (well, three actually, but one is "illegal" (ie: not allowed or suggested by good data management practices): by way of the adapter firmware or by way of the storage management software included with the adapter or available from the manufacturer's website (and hopefully already installed on your system). The process, as stated above is messy, and before getting into the details of what may well fail, let us know the brand of your RAID adapter, whether it's onboard or a discreet card, the firmware level of the card itself and the type (title) and revision level of the storage management software in use. With that info, we / I can assist you with a higher probability of success...
