xcopy /z does nothing!!!!

[Guest jameshanley39@yahoo.co.uk]

I am finding that the /Z switch on xcopy has no effect.

 

It works on Copy - copy /z

 

I am aware of what it does, and how it works. I have used it with

Copy.

 

Can anybody else see either

- the same problem with xcopy on their machine ?

- that it does have an effect on their machine ?

 

I am wondering if this is an XP problem

 

When I say xcopy with /z does nothing. I mean, xcopy behaves exactly

the same without it.

The effect of the /z switch will only become visible in cases when

a networking problem occurs during the copy process.

it seems you're right..

 

copy /z would resume even after a ctrl-c, with a network copy, as it

would when removing a cable. I assumed that xcopy would do the same

but no.

 

When one pulls the cable out. Then xcopy will do it. And it gives this

error

 

File creation error - The network location cannot be reached. For

information ab

out network troubleshooting, see Windows Help.

 

and it can be resumed.

 

once or twice though, after doing it many times.. maybe with or

without /z I don't know. It said after I pulled the cable. (it

couldn't reach the mapped network drive)

Invalid drive specification

0 File(s) copied

And in that instance, I am not sure what it did but it wasn't a

renewable thing.

If I could repeat the error I would be able to test that one further.

 

I can test for sure if it's resuming, by looking at the file with

xvi32 (binary file editor), and then finding the end (I do that by

going to the bottom and searching up for a non zero character, like

01 hex string. Then that gets me to near te end, from there I can see

the end and click to the end, and see the number of the last byte).

After doing a copy where I left it for say a while, maybe 20sec, to do

like 100MB, I can do a small copy, pulling the network cable out

quickly, and see if it is 9MB(obviously meaning it restarted it) or

over 100MB(meaning it resumed it).

xcopy /z does not provide a %, unlike copy /z. With copy /z, I can see

if it resumed 'cos it starts at the % it left off at.
