I am experiencing a a similar yet strange error. I am trying to rename chunks as I need to add to a new server, new drive and new directory. I am using -rename -p -o -n -o as I have spaces in my pathnames. Firstly I cannot specify offset 250( -o 250), I get an error - "Error in parsing command line at '250'". BUT I can specify 200, 240, 260, 300, 350, 400, 450 and 500????
I then use 200 as an offset, which is not equal to my 250 offset in my backup, then I get an error - "Physical restore failed - The old chunk path <C:\Program Files\....\admin_chunk1, 200> in the input file does not exist in backup."
Can you please assist with this? I am desperate, we need to present to potential customer.
