Hi all.  I seem to be having some issues with permissions on my machine.

I recently upgraded to 0.5.6 and installed a new 2 TB WD hard drive on my Windows 7 x64 desktop.  After upgrading SABnzbd+, I updated my config file to point to my new drive however, every download has failed ("Download failed - Out of your server's retention?").  Upon inspecting the log, I saw a number of lines such as:
2011-01-07 17:47:00,987::ERROR::[assembler:126] Disk error on creating file M:\Downloads\Incomplete\[CONTENT-FOLDER]\[CONTENT-FILE].r11
Which, as far as I can tell, means SABnzbd+ is unable to write to the drive correctly.  To troubleshoot, I tried setting my download folder to an existing drive, which ran succsefully, so I'm fairly certain it's a permission/accessibility issue with the new drive.  

A number of people tried to help me troubleshoot in the IRC chat, but we had no luck (thanks to those that tried).  A couple of the suggestions that were made:

Are you running it as an administrator?

Yes, I've tried doing the right click, run as admin, but no luck

What if you create that folder manually

No luck.  I created the folder manually in the incomplete folder, then started the download.  The folder I had created was deleted/unavailable once the download started

Did you try re-formatting the drive?  Doing a full format / diskcheck on it?

No i have not.  I'm hoping to not have to resort to that, but I guess I'm running out of options

Can you copy a file to it?

Yes, I can copy, save and download to the drive.  It's where my watched folder is located.  [So yes, it reads the watched folder and deletes NZBs from it fine].

I should also add that I've tried this with a number of NZB's, all with the same error.

Before I try reformatting the drive, does anyone have any suggestions?  If it matters, it's a Western Digital WD20EARS 2 TB drive.

What's the ACL of the new drive?
Open a command prompt and type:

cacls m:\Downloads\Incomplete

BTW: does m:\Downloads\Incomplete already exist?
If not, you need to look at the ACL of the root M:\
You did format the drive as NTFS?
Does the partition occupy the whole drive?
Cannot say we ever tested with volumes of 2T.
What happens if you only have the "complete" folders on the big volume
and "incomplete" on another disk?

[nickf]

Here's the ACL for the Incomplete folder (which was already created)
m:\Downloads\Incomplete NT AUTHORITY\Authenticated Users:(OI)(CI)(ID)F
                        NT AUTHORITY\SYSTEM:(OI)(CI)(ID)F
                        BUILTIN\Administrators:(OI)(CI)(ID)F
                        BUILTIN\Users:(OI)(CI)(ID)R

Yes, the drive is formatted as NTFS and the partition occupies the whole drive (1.81 TB)

I will try moving the "incomplete" folder to another disk as you suggested.

Thanks.

Keep me informed please.
Who knows, maybe it is a 2T limit problem.
