I have my OneTouch III Turbo connected via Firewire and I’m unable to use the Security Erase function.
Please note, Security Erase process only supports OneTouch III Turbo drive when the following two conditions are met:
1. Drive connected to USB interface
2. Drive is in Raid 0 mode. Running Security Erase in Raid 1 mode could cause the drive to be corrupted at the end of the erase process.
The software will reject the request and prompt user with a message when security erase process was attempted with 1394 interface cable.
Overview:
This Knowledge Base article describes a specific RAID reconfiguration; it describes how to re-configure the arrays using a Mylex Spanning feature to create a single 1.45 TB user volume spanned across Arrays 0 and 1 without a performance reduction. This procedure is data destructive for both user volumes. This procedure does not require the use of any special service tools. This procedure does not require system downtime, but the performance of the system will be affected significantly for about 10 minutes. System performance will also be slightly reduced for about 30 hours during the “background” creation of the redundant data…
The following procedure provides the steps necessary to configure a RAID 0 Volume on your Onetouch III Turbo Edition using the Maxtor OneTouch Manager for Mac:
- Open the Maxtor OneTouch Manager.
- From the main menu, select the OneTouch III Turbo drive and click select Settings.
- From the Setting screen, click the RAID tab.
- To create the mirror, click the RAID 0 for Speed button.
All data currently on the OneTouch III Turbo drive will be erased during this process. It is recommended that you backup any/all data stored on your OneTouch III Turbo drive before continuing.
Click Erase to proceed.
If prompted, enter your…

A comparison of usable drive space to physical disk drive capacity.
Overview: There are two main factors affecting your total system storage capacity:
- RAID Overhead
- Conversion between Binary and Decimal Byte “Equivalents”
In some cases, the overhead is 50% of the total hard drive capacity.
Comparing Binary and Decimal Equivalents:
The following Table charts common Binary/Decimal Values:
RAID Overhead:
With Raid 1 (Mirror) or Raid 5 (Strip Set with Parity), a certain portion of the disk space will be used for redundancy thus it will not show up as usable space.
Example of NAS 6000 Capacity Calculations:
The NAS 6000 base unit has twelve 160 GB hard…
The NAS 4000 Series is a file server. Maxtor highly recommends you make backups of the NAS, as you would with any server.
A RAID 1, or "mirror", is built from two disk drives, where one disk drive is a mirror of the other (ie, the same data is stored on each disk drive). Compared to independent disk drives, a mirrored volume provides faster performance, but has only 50% of the capacity.
The following provides the steps necessary to create RAID 1 volume. It is assumes the following:
- You have backed up any/all critical data off of the BlackArmor NAS Server.
- All previous unneeded Volumes have been deleted.
- You are currently logged into the BlackArmor Manager with admin privileges.
Procedure(s):
- Mouseover Storage and click Volumes. The Volumes…
A volume with RAID 10 is built from two or more equal-sized RAID 1 volumes. Data in a volume with RAID 10 is both striped and mirrored. Mirroring provides data protection, and striping improves performance.
The following provides the steps necessary to create RAID 10 Volume. It is assumes the following:
- You have backed up any/all critical data off of the BlackArmor NAS Server.
- All previous unneeded volumes have been deleted.
- You are currently logged into the BlackArmor Manager with admin privileges.
Procedure:
- Mouseover Storage and click Volumes. The Volumes page opens.
- Click the Add icon. The Volume Add Disk Selection page opens. Select the…
A volume with RAID 5 is built from a minimum of three disk drives and uses data striping and parity data to provide redundancy. (Parity is extra information that is used to re-create data if a disk drive fails. In volumes with RAID 5, parity data is striped evenly across the disk drives with the stored data.) Parity data provides data protection, and striping improves performance.
The following provides the steps necessary to create a RAID 0/1/5/10/Spanned/JBOD volume. It is assumes the following:
- You have backed up any/all critical data off of the BlackArmor NAS Server.
- All previous unneeded volumes have…
RAID 0 is also commonly referred to as "striping". RAID 0 is known for speed. When data is written to the RAID 0 volume, it is written to all drives striped together at the same time. Think of each interface as a water hose and the volume as the bucket; the bucket will fill faster if multiple water hoses are filling it at the same time. The same holds true for striping – data writes faster to the volume because it is being written through more than one drive interface.
The downside to RAID 0 volumes is the fact that…
