SyncToy access denied error on USB drive connected to NAS

Hi,

I am having the familiar access denied problem when trying to sync files from my XP 64 pc to a USB drive connected to a maxtor shared storage NAS.
I can sync just fine to the maxtor nas network drive but get the following error when attempting to sync to the USB drive attached to the NAS:

Error: Unknown error. Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)) Copying FILE_TO_BE_SYNCHED to USB_ON_NAS_BOX_FILE

I can read/write files just fine when connected to the drive on the pc.
Somehow the permissions are ok for the NAS drive but not the usb drive attached to it. I have tried to modify the security level on the USB drive but just get an access is denied error.

Hope someone could help as SyncToy looks like just what I need Smile

Can no one help  me out with this problem?!

 

Answer 2

Can you check this ? Map the USB drive  to a drive letter on the XP 64 bit machine and see if you can manually copy a file from the 64 bit box to the USB?

Thanks

Answer 3

Sorry I didnt make this clear in the original post but when mapped to the usb  drive (via the NAS) on the XP64 pc I can read/write files  no problem.

Anyone help  me out here?
 

Answer 5

I guess there is no fix for this issue, I hope  that MS will consider looking into this and fixing it for the next version of SyncToy.
 

Answer 6

It looks like your user does not have full controll of the usb  drive.  Can you check the USB drive  Security properties to verify that your user has full control?

As I mentioned the usb  should have full control rights as I can both read/write and delete files/folders from explorer. I cant access  the drive  directly as its connected  through the NAS, however there should be full admin rights.

I am having the same problem  as Kreeture.

I have an external usb  hardrive pluged into the USB port on the back of my BT Home HUB.

This allows me to share music, video etc over my wireless network, this all worls very well with no problems.

I maintane the original files  on my WIndows XP SP3 32 bit pc. Whenever I add additional files, I currently manually copy and paste from my PC onto the USB drive. This works ok, I can, from the main PC, copy read write & delete any files from the usb drive.

When I tried using SyncToys I get an error, Access denied. It does however creat any folder structure required on the USB drive, and creates a lot of .tmp files, but failes to copy the actual files over.???

I tested the process copy files from one folder to another on my pc's hardrive and it worled ok.

Anyone help  with this??

Thanks in advance

 

Answer 9

Can you check under which account the sync  is working?

Under which user's permissions  is the process running.

Trying giving full rights to the user.

Ensure USB drive  reg key has following properties:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies]
"WriteProtect"=dword:00000000

 

Answer 10

Hi Soshan, thanks for taking an interest in this.

I have only the one user account, ne and I an full administrator.

I checked the registry key you sugested, I have no "StorageDevicePolicies" in "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control"

Is this the problem?

Can I just create this key and reeboot?

 

Answer 11

Did this ever figured out?  Is there any workaround?  I'm having the same problem  with a USB drive  connected to my router (a Buffalo WZR-HP-G300NH).  I can copy and delete files  on this NAS drive, but SynToy 2.1 gives me the same "Access is denied" error  when it tries to write to the NAS drive.  I even get this when I try to sync  to a folder that I created from the same PC I try to do the sync (well actually Contribute).  One twist, I am only getting this error with my Notebook PC -- but not my Desktop PC (which SyncToy seems to work fine  with the NAS).
 

Answer 12

BTW, my desktop is running XP while my notebook is running 7.  I connected  my notebook to the router via a wired connection, and I still get the "access is denied" error.  So the problem  I am seeing with SyncToy 2.1 (and NAS drives) seem to only be with Windows 7 -- and not XP.  Or perhaps it is an issue with the 64-bit version of SyncToy (which I am running with 7) and the 32-bit version (that I am running with XP).  Either way, I'm hoping version 2.2 is released soon AND that it corrects this problem!

 

 

 

Answer 13

Same problem  here. I have a Hammer N1200 NAS configured as RAID 0. I use (or hope  to use) a USB SATA drive  as a backup. SyncToy 2.1 fails to synchronize most new files.

The Hammer drive seems to be running Linux.

I run SyncToy from a WinXP workstation. I have tried full path names as well as mapped drives, both modes result in the same failures.

Operation: Overwrite

Error: Unknown error. Access is denied  (Exception from HResult:0x80070005(E_ACCESSDENIED))

 

Operation: New

Error: Unknown error. Access is denied (Exception from HResult:0x80070005(E_ACCESSDENIED))

 

I've tried both Synchronize and Contribute modes. Both fail in the same manner.

 

Answer 14

Long time no answers?

I have the same problem  under Win7 32bit, trying to Echo from a Public Share on my NAS to a USB 1TB disk drive  attached to it (Both WD).  Like Bugss the folder structure was created, but no files  were copied.  Ie was logged in as an account with admn prives, but the permissions  on the folders did not include me specifically.

I have copied a lot from C: to the same drive using SyncToy.

If I find an answer I will post it here.
