RAID 1 on two SATA HDDs on vantec NexStar MX

Hi All,

Here are some details of the stuff that I am using or having:

OS: Win XP (Pro) or Win 7 (Home edition)

HDDs: 2 of 2TB Western Digital (Volume labels: WD 2TB A / WD 2TB B)

External Enclosure: Vantec NexStar MX - Dual 3.5'' SATA to USB 2.0 and eSATA With JBOD/RAID 0/1

Info: Both HDDs are formatted to NTSF Basic. Both are running fine.

On the Vantec external enclosure, there is an option to set RAID 1 (switch 1 & 2 are on, 3 & 4 are off.

When I hook up the external enclosure via USB 2.0, I am able to see both drives under my Computer.

I am trying to keep a mirror disk. But when I copy some files (for testing) on
the WD 2TB A drive, it should copy the same thing on the WD 2TB B drive. It is not doing that. I tried the vise versa option (copy files to WD 2TB B and it did not copy automatically to WD 2TB A).

Is there any other config or software or drivers that I need to setup/config to get this RAID 1 working ? Please help. Thanks. If you need further info, let me know.

Thank you very much

  1. read up on the RAID compatibility of you WD drives. Some do not work well in RAID since they do not support TLER.
