BCP and reset batch size

Hi there,
I'm using SQL Server 2008 and Windows Vista X64
I run this bcp on a table with 8.2 million rows
Exec Master..xp_cmdshell
'bcp "Select * from Coronado.dbo.logprogressnotes" queryout "C:Tempsqlexport.txt" -c -T -Slocalhost'
Here are the results:1000 rows successfully bulk-copied to host-file. Total received: 8289000
NULL
8,289,683 rows copied.
Network packet size (bytes): 4096
Clock Time (ms.) Total : 88219 Average : (93,967.09 rows per sec.) 1min 28 sec.
NULL
C:TempSQLExport.txt 1,599,460 KB -> 1.6GIG
Now I modified the command by adding -b1000 to it and it took 4.5 min to run and 28,000 rows per secoond
Since then every time I run this command without -b it allways show me 1000 rows and is 3 time slower
My question is how to reset the bcp that way it will run with no batch size limit
Like it was in the first time I run the command? like reset the utility
Thanks,

don't use -b option, in that case bcp insert all rows as one transaction , with better performance.
For -b size , as size increase , performance is better
