1541Ultimate - Back to root dir

[MIRKOSOFT]

Hi!

I have problems to going back to root directory at accessing SD-card directly.
Command "CD:.." is not problem, works.

But command "CD:/" works not - in manual is written this pattern.

So, I tried alternatives e.g.:

"CD://"
"CD/"
"CD//"
"/"
"//"

but never it was successful.

Can anybody explain me how to use command back to root?

Thanks for every helps.
