Comment 27 for bug 207137

I'm getting the same error at the end of the "Creating image ..." step in Wubi, just after reaching the 100%.
The message is "Could not access CD, please make sure other applications are not using it and try again".

The error in the log is:
CD2ISO C:\ubuntu\install\installation.iso
CD2ISO failed: LastError = 1 Incorrect function.

The media I used is a CD-R burnt using a DVD writer with Nero and finalizing the CD. My device is a "TSSTcorp DVD+-RW TS-L532B" as reported by Nero 6.

I called the function GetDiskFreeSpaceExW for the D: drive and gives me 733079552 of total bytes, the same size as the ISO file I downloaded.
I checked the md5 of the downloaded ISO file and is the same as the original one (8895167a794c5d8dedcc312fc62f1f1f ubuntu-8.04-desktop-i386.iso).

Hope this helps to find the issue.

* This is the Python script I used:

from ctypes import *

drive = "D:\\\\"
freeSpace = c_ulonglong(0)
availableSpace = c_ulonglong(0)
totalSpace = c_ulonglong(0)
rv = windll.kernel32.GetDiskFreeSpaceExW(unicode(drive), byref(availableSpace), byref(totalSpace), byref(freeSpace))

print totalSpace.value
