Like I said; you insert the drive and the raid controller handles everything else itself. You don't have to format anything.   Or do you want to keep your raid 10 in a degraded state and set up the 146GB drive as a single disk (raid 0)?
Dear All, I have Dell Power Vault 220S that installed with Dell Power Edge 2950. 1 disk on Power Vault 220S is broken, and I want to replace it with new one. Broken disk capacity is 36 GB and I want to replace with 146 GB. That I want to know are : 1). Is there any safe procedure to replace broken disk with different capacity ? 2). How to format new hard drive ? cause I get information from other to format the disk first before replace its. Thanks for attention   Regards Yosep
