External Usb Drives; Storage - ZyXEL Communications NAS326 User Manual

A user can access a share but cannot access individual folders or files within the share.
• Check the read/write permissions associated with the share's specific files and/or folders. Account
names added to the list are linked to the files and folders that they are allowed to access, along
with what kinds of actions they are allowed to perform with those files and folders (delete, move,
rename, and so on).

20.7 External USB Drives

The COPY LED is red.
Copying files to or from a USB device or SD card failed. The USB device or SD card may not be
compatible with the NAS. Try to save the files onto a computer and then from the computer to the NAS
(through the network connection).

20.8 Storage

Migrating from RAID 1 to RAID 5 did not expand the storage capacity.
The NAS normally expands the storage capacity by itself after rebuilding the RAID but may not if the NAS
rebooted during the RAID re-build.
After the re-build finishes, go to the Storage Manager screens and select the volume or disk group and
click Manage and use Expand the volume with unallocated disk space.
Replacing smaller disks in a RAID 1, RAID 5, or RAID 6 with larger capacity hard disks did not

rebooted during the RAID re-build.
After the re-build finishes, go to the Storage Manager screens and select the volume or disk group and
click Manage and use Expand the volume with unallocated disk space.
