ZyXEL Communications NSA-220 User Manual

 Chapter 15 Troubleshooting

NSA-220 User’s Guide

• Check that the NSA is turned on and connected to the network. Try to ping the NSA or use 

the NDU to discover it.

• Check that you entered your login name and password correctly.

• Check that the share exists and check its access settings.

• Check if the shared folder is a subfolder of another (parent) share. Check that the parent 

share’s access rights do not conflict with the subfolder share. It is recommended that you 
do not create subfolder shares.

• Check if there are any existing mapped network drives to the NSA. You may need to 

disconnect existing mapped network drives as a new mapped network drive connection 
may use (different) previously-saved login information. To do this, open Windows 
Explorer and click Tools > Disconnect Mapped Network Drives.

• Check that the volume in which the share resides, exists and is not down or degraded. If it 

is down or degraded, see 

• Make sure you have the client for Microsoft networks installed and enabled in your 

network connection’s properties. 

• In Windows XP or 2000, click Start > Settings > Control Panel > Network 

Connections (Network and Dial-up Connections in Windows 2000/NT) > Local 
Area Connection > Properties. 

• Check that Client for Microsoft Networks is in the list of components and has its 

check box selected.

V

My external USB drive is read-only.

If your USB drive was formatted as NTFS, then it is read-only on the NSA (the volume status 
displays as OK). To solve this problem, re-format your USB drive using the NSA (or FAT or 
FAT32 using a computer). See 

 for information on volume creation using 

the NSA (recommended). Back up the files on your computer before you format the USB 
drive.

V

The COPY LED is red.

Copying files from a USB device failed. The USB device may not be compatible with the 
NSA. Try save the files onto a computer and then from the computer to the NSA (through the 
network connection).
