Hello Andrey - many thanks for that. I have now removed /etc/passwd and /etc/group which didn't change anything.
I read some of your earlier posts on this and had already tried the noacl route. Unfortunately it has made no difference. I added a second line to my fstab so it read: none /cygdrive cygdrive binary,posix=0,user 0 0 e: /cygdrive/e ntfs noacl,binary,posix=0,user,auto 0 0 with "mount" showing: C:/cygwin/bin on /usr/bin type ntfs (binary,auto) C:/cygwin/lib on /usr/lib type ntfs (binary,auto) C:/cygwin on / type ntfs (binary,auto) E: on /cygdrive/e type ntfs (binary,noacl,posix=0,user) C: on /cygdrive/c type ntfs (binary,posix=0,user,noumount,auto) D: on /cygdrive/d type ntfs (binary,posix=0,user,noumount,auto) N: on /cygdrive/n type smbfs (binary,posix=0,user,noumount,auto) P: on /cygdrive/p type smbfs (binary,posix=0,user,noumount,auto) But when creating files on an E: I still get DENY for "NULL SID" and other accounts.
