Adaptec 2810SA added new drive, now what?
I just added a new 250G drive to a 3-drive raid 5 system (making 4
drives now) and although the Adaptec Storage Manager shows all 4 drives as being part of my raid 5 (TomRaid), the extra space does not show up in My Computer and it shows as an unused volume in Disk Manager. What do I have to do in order to make Windows see it as part of the capacity of my raid array? |

Use the DISKPART command-line utility (XP and 2003 itīs integrated in the basic-OS, under 2000 and NT itīs part of the resource kit) and EXTEND the volume. Will only work if itīs a basic disk and primary partition. No dynamic disks and no extended partitions/logical drives. Read the documentation beforehand and - as always - have a good backup of your data. HTH Etti DoD #2503 |

Thanks for the response, Michael.
I don't understand some of the terms used like "basic disk" and "dynamic disk". Can you elaborate? Thanks. Ettengruber wrote: wrote in message ups.com...

wrote in message oups.com... Thanks for the response, Michael. I don't understand some of the terms used like "basic disk" and "dynamic disk". Can you elaborate? Right-click on My Computer -- Manage -- Disk Management. On the left side where you see your disks (Disk 0, Disk 1...) On the label is either "Basic" or "Dynamic". If the disk is "dynamic" the extension process will not work, if itīs basic no problem. For the difference between basic and dynamic disks have a look into the help and support center of your windows system. Itīs quite elaborative on the subject :-) One additional free advice: If you donīt know exactly what youīre doing. Donīt do it! Managing disks is potentially very very disruptive and can lead to unrecoverable data loss. HTH Etti DoD #2503 |

I don't understand some of the terms used like "basic disk" and
"dynamic disk". Can you elaborate? "Basic Disk" - usual partitioned disk with MBR. "Dynamic Disk" - disk partitioned with Veritas's "dmio" (which MS has OEMed), which has a LDM database. w2k and later support software RAIDs only on Dynamic Disks. -- Maxim Shatskih, Windows DDK MVP StorageCraft Corporation http://www.storagecraft.com |

You can extend a simple volume if the extension will occur within its original physical drive or onto additional physical drives. 5..

I saw all that stuff in the help file but didn't think I understood it.
I still don't think I understand it because although it said that I couldn't extent a Raid 5, I was able to through windows. I just had to turn the Raid array "disk 1" in to a dynamic disk. Then I was able to extend the pre-existing raid volume with the new volume to get the full disk size I was expecting. This was done with XP. |
