I'm not familiar with NTFS but the thought of this scares me, I expect you'd be opening yourself up to a world of hurt as: a) NTFS isn't a first class citizen of Linux. b) according to wikipedia NTFS has a 255 character filename limit - I don't know for certain this is a problem but I wouldn't be surprised if it is. Will you be storing anything on the disk that isn't build related? If you anticipate doing a lot of builds you really want to a) use a filesystem that is Linux native and b) tweak the filesystem to reduce the number of writes made. If you just want/need to be able to look at the build system pieces under WinOS then you could try: http://www.ext2fsd.com/ Cheers, Joshua -- Joshua Lock Yocto Project "Johannes factotum" Intel Open Source Technology Centre
