You will have problems if any system writes to a shared filesystem. The buffering in Unix, Linux and Windows will make a filesystem inconsistent unless the filesystem has some kind of clustering support built in.

For filesystems supported on both OSes, then yes, you can. You still need to coordinate access if both systems have R/W access to a volume at the same time, but the data is directly accessible. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
