OK, i have sorted the write permition on the hdd itself, now i have write permitions to the share from windows but not linux.

here is the mount command i use to mount the
smbmount \\\\192.168.0.1\\data /home/exio/fileserver -o username=exio workgroup=sxpb

*****smb.cof*******
[global]

workgroup = SXPB
server string = Samba Server
log file = /var/log/samba.%m
max log size = 50
security = exio
encrypt passwords = yes
ssl CA certDir = /etc/ssl/certs
socket options = TCP_NODELAY
smb passwd file = /etc/samba/smbpasswd

[data]
comment = Nick's Service
path = /data/nick
read only = no
writable = yes
public = yes
write list = exio
********************8
i dont know if i need all them... e.g do i need 'read only' if i have 'writable' or 'public'...

any ideas why i do not have write permition under linux????

Manny Manny thanks, Nick.

I've just begun playing around with samba, so I'm no expert, but what do the server log files say??? They usually give a good indication if it's a password/configuration/permissions issue.
