"open for read error" message

Question

A recent firmware update (2.1 for MAcBooks) caused many of us to lose use of our superdrives. Someone figured out a fix that involved "flashing" the drive by running a program he wrote from Terminal. It worked for quite a few people but when I tried to run it instead of executing the program the message "open for read error" was returned. The command was "./simple_flash 0 UJ857-KBVB-MBP-rpc1.dat" which was supposed to start the simple_flash executible which referred to or used the .dat file.
Does anyone know what the "open for read error" is telling me? How can I resolve whatever it is that is preventing execution.
Thanks very much. Many are buying new superdrives to solve this problem but that is expensive.

Answer 1

I would say to take your machine into an Apple Store, but judging by your profile, I think that might not be feasible.
Where are you running this from? I downloaded it and looked at the source and that error just means that it can't open the dat file. Actually, it means that it can't even find the dat file. In the Terminal, you must use "cd" to move to the directory where the "simple_flash" executable and the .dat file are located. Do an "ls" and, if they are both listed, it should work.
