There seems to be something broken in the 1.6 beta (I think the log says it's related with the 7zip). I lent a USB pen to a friend and it returned with a nasty virus that screws low level information of partitions. I have used some tools from HDDGuru.com to erase/format the pen (because Windows can't even mount it or format it). They are stanalone .exe files but are only available in setups so here comes UniExtract to the rescue. Strange thing is 1.6 failed and 1.5 succeeded (even if using the same version of 7z.exe and 7z.dll)... http://hddguru.com/content/en/software/200...-HDD-Wipe-Tool/ http://hddguru.com/content/en/software/200...el-Format-Tool/ P.S: I also have some suggestions: 1- How about LesMSIerables for MSI extraction (seems to do the job without the dummy installation... but requires .NET 1... but it comes with the source). I couldn't find it online anymore... Here's an upload: http://dodownload.filefront.com/10498867//...ef1147c497d3cb2 Or as an alternative (the unpakers seem to work fine): http://www.jsware.net/jsware/msicode.php3 2- IAT can supposedlly convert BIN, MDF, PDI, CDI, NRG, and B5I into ISO-9660 (I wasn't abble to use it though...) http://iat.berlios.de/ 3- I agree with DAA2ISO. Add UIF2ISO to the list: http://aluigi.altervista.org/mytoolz/uif2iso.zip I couldn't find any free (small) tool to convert CCD2ISO or IMG2ISO (I did find a page with link to convert any images to ISO... but for Linux... some of these xxx2ISO projects are also available for Windows even if in different webpages): http://wiki.linuxquestions.org/wiki/CD_Image_Conversion.
