Solved External eSata drive connected as RAID

Specs: Windows 7 64x, Core i7 930, 8GB
I have an eSata connected 2TB external drive connected to my Gigabyte X58A-UD3R mobo. Everything works fine but I noticed that the interface is listed as RAID. Is this a problem? I thought RAID was used with 2 or more drives.

Look at Windows Disk Management and see if the capacity for that drive is listed as 2TB there.

Depending on what type of RAID array that would have been configured that number could be something different.

For instance, if your primary hard drive and the eSATA were configured as RAID-0 the array capacity would equal the sum of both drives. That is one possibility.

I have not used an eSATA connected drive so I am unsure how it should appear. Is the drive functioning as expected?

Thanks for your reply. The esata external drive has full capacity of 2TB and works perfectly. I know very little about raid and I am beginning to think the reason the external esata drive was installed with a raid interface may be because I am using IDE rather than AHCI. This is because I have Windows XP installed on my secondary (D:) drive and this OS cannot work with AHCI.
I believe I may have answered my own question. I thank you again for your efforts.

You may be correct in that assessment. SATA controller cards are usually set as RAID too. See the link below for related information.
