View Full Version : Win 7 Viewing Hard drives on PC

03-11-2009, 05:58 AM
Hi Guys,

I've installed win 7 64 bit onto a separate hard drive on my pc.
When viewing the bios I can see that it has detected 3 hard drives on my system.
1st HD has Win XP 32bit OS.
2nd HD has Win 7 64bit OS and
3rd HD is an external HD containing movies etc and connected via USB.

I can boot into either OS no problems and everything is working fine except for this small detail.

In Win 7 Using windows explorer I can only see the external HD and the HD containing the Win 7 OS, yet using device manager it show that there is another HD there.

In Win XP I can see AND access all 3 HDs, so if I need to copy anything across either OS from the 1st HD I have to do it while using win xp.

Both OS can access the external HD no problems.

Is anyone else seeing this behavior? Both HD's believe that they are the "C:" drive, yet win xp sees the win 7 HD as local HD "E:".

It seems Win 7 cannot/has not allocated a drive letter to the win xp HD.

Wonder if that has anything to do with 32 bit v 64 bit systems?

Apart from that I'm loving the Win 7 OS. Think MS may be at long last onto a winner with this.

I was looking it up for you and turned on my WIN 7 computer, and I got the big bad blue screen.... haven't had that before. :(

Anyway, I believe you have to MOUNT or MAP the drive (open up computer), or something like that. I had the same problem and found the answer in MS WIN 7 help site.

Until I get my comp back up and running that's the best I can do :( LOL

You need to assign a drive letter to your XP drive.

You can change, add, or remove a drive letter by using Computer Management.
1. Open Computer Management by clicking the Start button, clicking Control Panel, clicking System and Maintenance, clicking Administrative Tools, and then double-clicking Computer Management.http://windowshelp.microsoft.com/QueryWS/GetOpenContent.aspx?assetID=18abb370-ac1e-4b6b-b663-e028a75bf05b&DocumentSet=en-US&RenderKey=XML If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
2. In the Navigation pane, click Disk Management.
3. Right-click the partition (http://javascript<b></b>:p('75f2da20-91f7-4f31-8e17-798cce2c38c11033#gtmt_partition_def', 'E2C')) or drive that you want to change, and then click Change Drive Letter and Paths.
