I am trying to run Instantcake to make a new drive for my Series 3 HD unit. I'm not a Linux guy but I can see in the bootup that the target drive is identified as being connected to the USB port as drive sdb. The problem is that Instantcake wants to know how my CDROM drive is connected and what the drive ID is for it. The best I can tell under Windows Device Manager is that the CDROM is connected as a SATA device (no PATA controllers) but no clue as to the drive ID (e.g.: sdc, sdd, etc.) except that it connects as Windows drive D:. I entered SATA and sdc but Instantcake rejects that combination. Guess I could keep experimenting but thought this forum might provide a quicker answer. The laptop is an ACER 5742 (the i3 processor version). UPDATE: I tried the Linux command "ls -l /dev/cdrom" and it tells me that the CDROM is device "hdb" but Instantcake still doesn't like that designation.
