It is very much possible<BR />2. However, you will not be using 36GB of the HDD with 72GB capacity<BR /> Wed, 06 Dec 2006 08:22:46 GMT https://community.hpe.com/t5/disk-enclosures/array-with-two-size-diferentes-hard-disk/m-p/3907979#M22405 The Spartan 2006-12-06T08:22:46Z https://community.hpe.com/t5/disk-enclosures/array-with-two-size-diferentes-hard-disk/m-p/3907980#M22406 thank you!<BR /><BR />One question more. When I create RAID1 with two disk, I have one logical drive of 36GB, but 36GB space free. Can I lost free space disk no used?<BR />Sorry my english is poor.

It will not even show in ACU.<BR /><BR />Steven Wed, 06 Dec 2006 16:20:52 GMT https://community.hpe.com/t5/disk-enclosures/array-with-two-size-diferentes-hard-disk/m-p/3907981#M22407 Steven Clementi 2006-12-06T16:20:52Z
