"Volume failed to mount" - Mac -> WinXP Festplattenzugriff via WLAN

[fasto]

Folgendes Problem auf einmal (das macht mich seit 2 Tagen wahnsinnig):

Mein WinXP-Rechner hat 3 Festplatten, 2x intern (NTFS, S-ATA) und 1x extern (NTFS, USB) .... mit meinem Macbook (Leopard 10.5.6) kann ich auf beide internen Festplatten problemlos via smb:// auf die freigegeben Verzeichnisse zugreifen, auf die externe USB-Festplatte klappt der Zugriff urplötzlich (seit 2 Tagen) nicht mehr. Habe an beiden Systemen nix verändert.

Im Finder wird unter "SHARED" mein Windows-Rechner automatisch angezeigt, unter "Connected as: Guest" werden auch alle Windows-Freigaben (Verzeichnisse/Laufwerke) korrekt angezeigt. Zugriff auf die internen Festplatten funktioniert wunderbar.

Wenn ich aber auf die externe Windows-Platte klicke, so kommt folgende Fehlermeldung: "The operation cannot be completed because the original item for "HD3" cannot be found" .... wenn ich via Finder > Go > Connect to Server klicke und die korrekte IP (smb://1xx.xxx.x.xxx) eingebe und auf "Connect" gehe (Name/Passwort eingegeben) dann kommt das PopUp (Select the volumes to mount) mit den korrekten Freigaben, wenn ich dort auf die USB-Platte klicke, dann kommt diese Fehlermeldung: "A volume failed to mount. The volume HD3 could not be mounted."

Irgendein Lösungsvorschlag? Wie gesagt, vor 2 Tagen hat alles noch bestens geklappt.

Danke vorab.

Okay, hab eine funktionierende Lösung dank Google gefunden:

Try changing the IRPStackSize in the Windows Registry.

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:
322756 (How to back up and restore the registry in Windows ) How to back up and restore the registry in Windows
To resolve this behavior, increase the IRPStackSize value in the registry:

1. Click Start, and then click Run.
2. Type regedit, and then click OK.
3. Navigate to the following key:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanServer\Parameters
4. In the right pane, double-click the IRPStackSize value.

NOTE: If the IRPStackSize value does not already exist, use the following procedure to create it:
1. In the Parameters folder of the registry, right-click the right pane.
2. Point to New, and then click DWord Value.
3. Type IRPStackSize.

IMPORTANT: Type “IRPStackSize” exactly as it is displayed because the value name is case-sensitive.
5. Change the Base to decimal.
6. In the Value Data box, type a value that is larger than the value that is listed.

If you created the IRPStackSize value using the procedure described in step 4, the default value is 15. It is recommended that you increase the value by 3. Therefore, if the previous value was 11, type 14, and then click OK.
7. Close the Registry Editor.
8. Restart the computer.

If the problem persists after you complete the preceding procedure, try to increase the value of IRPStackSize even more. The maximum value for Windows 2000 is 50 (0×32 hex).

If you are running Windows NT 4.0, and the problem persists after you complete the preceding procedure, you may have to apply Windows NT Service Pack 4 or Service Pack 5.

************************************

In Windows NT 4.0, the default value of IRPStackSize is 0×4, and the range is from 0×4 to 0xC (4-12). Windows NT 4.0 with Service Pack 5 or later ignores values less than 0×7.

In Windows 2000, the default value of IRPStackSize is 15, and the range is from 11 to 50. In Windows XP, the default value for IRPStackSize is 15, and the range is from 11 to 50.

NOTE: The default and range of Microsoft Windows Server 2003 is the same as that for Windows XP. For more information, click the following article number to view the article in the Microsoft Knowledge Base:
106167 (Error message: "Not enough server storage is available to process this command" ) Error message: Not enough server storage is available
NOTE: The preceding article recommends that you increase the IrpStackSize value; however, if you increase this value to its maximum (for example, if you increase this value to the maximum value of 12 on a computer that is running Windows NT 4.0, or to the maximum of 50 on a computer running Windows 2000), this behavior may still occur.
