Can't see NVFS on E2?

[Rob]

Hi folks,

I have a user reporting that my app (Preference doctor) can't see the nvfs  
on his E2.
All I'm doing is looking for the NVFS vol ref using the code from the Palm  
companion. It works fine on my Lifedrive and treo, but I don't have an E2  
to check.

Can anyone help?

Thanks,
Rob

//returns  NULL if not found
UInt16  NVFSVolRefNum(void)
{
UInt32                          volIterator;
UInt16                          otherVolRefNum;
VolumeInfoType          volInfo;
UInt16                          volRefNum=NULL;
Err                                     error;

//find NVFS volume
volIterator = vfsIteratorStart | vfsIncludePrivateVolumes;
while (volIterator != vfsIteratorStop)
        {
        if ((error = VFSVolumeEnumerate(&otherVolRefNum, &volIterator)) 
==errNone)
                {
                error = VFSVolumeInfo(otherVolRefNum, &volInfo);
                if (error)
                        break;
                        
                if (volInfo.attributes & vfsVolumeAttrHidden)
                        {
                        // This is an internal file volume. Perform actions 
now...
                        volRefNum=otherVolRefNum;
                        }
                }
        }
return volRefNum;
}

I call this here:
static Err RomVersionCompatible(UInt32 requiredVersion, UInt16 launchFlags)
{
        /* See if we're on in minimum required version of the ROM or later. */

if (!NVFSVolRefNum())
        {
	if ((launchFlags & (sysAppLaunchFlagNewGlobals | sysAppLaunchFlagUIApp))  
==
                        (sysAppLaunchFlagNewGlobals | sysAppLaunchFlagUIApp))
                {
		FrmCustomAlert (InfoAlert,"You don't have NVFS on this device - so you  
don't need PrefDoctor\n\n(That's a good thing!)",NULL,NULL);
                }

        return sysErrRomIncompatible;
        }

return errNone;
}
