help, hardrive letter change confuses Blender

I’m trying to work on a Blender image at two computer locations. I’m using a portable hard drive.

Trouble is, at the first computer, when I plug in the hard drive it becomes drive K:
When I plug it into the second computer, it becomes drive H:

The model has a couple of UV image maps loaded as textures. I did put the texture *.bmp files in the same directory as the *.blend file. But in the stored path to the file, the path begins with “K:”

So everything works fine on the first computer. If I go to the second computer and try to open the *.blend file, it opens the mesh, but then an error dialog box stating “There is no disk in the drive. Please insert a disk into drive \Device\Harddisk2\DR4.”

Pressing the “cancel”, “try again”, or “continue” buttons seems to make the error message re-appear, no matter how many times you press them. The only way out is to click the “X” go-away button in the upper right corner of the Blender window.

Is there any way to avoid this?

Yes. You can “pack” your UVimages inside the .blend file (but it’s size will increase) so you don’t have path problem.
On the File menu, choose “Pack data”. This will pack all the images you used.
If you want to pack images separately, there’s also a like icon (looking like a cardboard box) for packing/unpacking images, on the right of the image name, on the UV window.
(and also on the right of the “Load image” button on the texture panel, if you want to use an image as a texture)

If your images are in the directory where your blend is (or a subdirectory) when you open them, make sure to choose ‘Relative Paths’ in the file selector. This will store the location relative to the blend as opposed to full file paths.

You can then work on system to system without issues.

(though I have a sinking feeling that both of your answers were sitting in the manual, patiently waiting for me to read it. I did try looking it up in the index)
