I've been using my 20080224 version of pyTivo with no major problems until I set it up to use a USB drive attached to me 64bit W2k3 Server.

All shares are working fine except this one:
[My Videos 2]
type=video
path=J:\
#precache=true

The error that appears in the console version is:
----------------------------------------
Exception happened during processing of request from ('192.168.1.242', 4841)

WindowsError: [Error 5] Access is denied: 'J:\\System Volume Information/*.*'

I don't seem to be having any problems using the drive in Windows or over a Windows share, but oddly enough, Windows Explerer Properties reports the file system as "Raw" while Disk Management reports it as NTFS - so I'm assuming it's a drive formatting issue.

Oh - and the same error appears if the I mount the drive in an empty NTFS folder. It's curious, though, that the folder lists 6 items, though shows the error & "This Group Is Empty" when I try to go into it. I wonder where the "6" comes from - the drive has 3 subfolders in the root.

By using the command below (ref: http://support.microsoft.com/kb/309531) I was able to solve the issue for me J drive:
cacls "j:\System Volume Information" /E /G JMVDW:F

Side Effect: I now see the System Volume Information folder in my share. Sigh.

Oh - and for those that are keeping track, folder shortcuts do NOT seem to work, but NTFS mounted folders DO seem to work.

I thought I should mention it here in case others run into similar issues with NTFS external devices and permissions issues.

Anybody know why pyTivo needs System Volume Information access to begin with?

Wow, I don't know anything about that at all.

What made you look to that knowledgebase article on microsoft.com?

Edit: You know if this is an issue I can specifically tell pyTivo to ignore folders names "System Volume Information". Then you wouldn't have to do the above reconfiguration.

Edit 1: Wouldn't this be an issue for any folder which a user didn't have access to? Maybe the proper thing to do is to add an exception catch to skip these folders.

Did this cause pyTivo to crash on you? Or it just displayed errors?

Ahh I see what happens. Once it hits that folder the pyTivo server hiccups and the folder on the TiVo goes empty.

I was able to do this by putting in a folder into my share that pyTivo would not have access to.

This is more than just a "system volume info" issue.

I am going to work up a patch right now for folders that can't be opened.

Ok I made a patch to this. If pyTivo comes across a folder that it does not have permission to view it will no longer cause it to choke.
