Windows 7: How to read drive channels

How to read drive channels

I have an Asus M3A76-CM MB with 6 available SATA ports...here is what is being reported in device manager:

ST31000333AS

Location 0 (Channel 2, Target 0, Lun 0)

ST31000340AS

Location 0 (Channel 0, Target 0, Lun 0)

ST32000542AS

Location 0 (Channel 1, Target 0, Lun 0)

in physically looking at the MB, I see that the SATA cable for the 542 is in the 3 position (facing the MB looking down), but is there a way to determine which drive is C: and what is D: (the 542 is being assigned F:, and the CD/DVD is E.

Any ideas?

Look in the BIOS on the first page. It should list the drives.
Next go into the BOOT menu and look at the Drive configuration section. There you can change what the BIOS reports to the OS as the first/second/third and so on drives in the system. Then go to Boot order and if the PC is booting properly it will list the drive it is presently going to try and boot off of.

I will do that (probably tomorrow)...I have been able to determine that the new drive is in Channel 2 and the DVD-ROM is in channel 4 (right where device manager said it would be). Would it be too much of a stretch to say that Location 0 (Channel 0, Target 0, Lun 0) is drive C (assuming that is the first drive that shows up in the BIOS menu)?

What I am planning to do is to move about 850GB of media from drive D: to the new 2TB Drive F:, then run it for 24 hours (without mounting the 2TB physically), then powering down and mounting it permanently.

I just wish that Win 7 would say that Drive Model <x> is drive letter(s) <w, y, z>, etc

G'day dogbert2.

This may be of help to you.

Click on the windows orb. (left bottom corner of your screen.
Then, on the right side, click on "Administrative Tools".
Next "Computer Management.
Next on "Storage".
Then "Disk Management".

Here you should find the answer you are looking for.
Others with much more knowledge than myself, may have better answers.

I found the needed information using DISKPART via the command prompt. The 340AS is drive C: and is on Ch0, Target0, Lun0.

Here is a URL for people who have multiple drives in their system and need to figure out which drive is which:

Understanding Disk Location Paths

The commands needed are:

DISKPART <enter>

select disk=system <enter>

detail disk <enter>

Actually I have never seen a reference to the SATA channels (Ports) listed like that.
Could you post a screen shot of where you are seeing this.

If you look in the manual for the board is should point out numbers for the different SATA connectors. SATA 0/1/2/3.
I place my drives on the port numbers as I want them to show in the OS. Boot drive goes on Port 0 and so on. Then I check how the BIOS sees them. On my Asus board, a P7P55D-E Pro, it's a little screwed. I had to place the drive I wanted to be second in Win Explorer (actually my drive E because my boot drive has 2 partitions) on the third SATA port instead of on the second port.

I got that information from device manager, but the command DISKPART was able to give me the information I needed as to which drive is the Boot Drive (see post above yours for information)

Go to Device Manager and right click a drive and select Properties then Volume and hit Populate and it will list what is on that drive.
