Shared Folders and USB Ports
There are several restrictions on using the AirStation’s USB port:
• When using two-byte characters (such as Japanese), keep folder and file names within 80 characters. You may not be
able to copy a folder or a file whose name length is more than 80 characters.
• You cannot set attributes (hidden or read-only) for folders or files on the AirStation.
• When using access restrictions, you can register up to 16 users for the AirStation.
• Please note that you are not allowed to use any of the following words as a user or group name: adm, administrator,
all, bin, daemon, disk, ftp, guest, halt, hdusers, kmen, lp, mail, man, news, nobody, nogroup, none, operator, root,
shadow, shutdown, sshd, sync, sys, ttyusers, utmp, uucp, www.
• Please note that you are not allowed to use any of the following words as a shared folder name: global, homes,
printers, bittorrent, disk1_pt1, disk1_pt2, disk1_pt3, disk1_pt4, disk2_pt1, disk2_pt2, disk2_pt3, disk2_pt4, disk3_
pt1, disk3_pt2, disk3_pt3, disk3_pt4, disk4_pt1, disk4_pt2, disk4_pt3, disk4_pt4.
• If a file created on a Mac contains any of the following characters, it will not be displayed correctly under Windows.
Also, you cannot copy or properly display a file when connecting via SMB from Mac OS if it contains any of these
characters:
? [ ] / ¥ = + < > ; : “ , | *
• Cancelling or aborting a file copy may leave the file incomplete, and you may no longer be able to delete the
incomplete file. This can also happen during a power outage or if the LAN cable is suddenly disconnected. If it
happens, restart the AirStation, delete the file, and try copying the file again.
• Use the same username and password for the AirStation as the user’s Windows login. If they are different, the user
may not be able to access shared folders with access restrictions on the AirStation.
• Date and time stamps stored on the USB hard drive may be updated by the OS accessing the AirStation. File creation
or access dates may not be maintained.
• If you view the size of a hard drive from Settings, it shows a bigger value than when you see it in Windows’ drive
properties. This is because Settings shows the size of the drive in gigabytes but Windows shows it in gibibytes.
• If you have logged in using a “guest” account from Windows 8, Windows 7, Windows Vista, Windows XP, or Windows
2000, access restrictions may not work properly. A (different) guest account already exists on the AirStation.
• If you access a shared folder from a Mac, additional Mac OS information files may be automatically generated. Do not
delete these files from a Windows computer. Otherwise, you may no longer be able to access folders from a Mac.
• Device types that can be connected to the AirStation’s USB connector are USB hard drives, USB memory sticks,
USB printer, or USB card readers. Card readers with 5 or more slots are not supported. USB devices such as digital
cameras, CD/DVD drives, mice, and keyboards are not supported.
• Encrypted USB hard drives are not supported.
• If your hard drive has an auto power mode switch, move the switch to [manual] or [on] position. Leaving the switch
set to [auto] may result in unpredictable behavior.
• Up to 4 partitions can be recognized on a USB hard drive.
• Available file systems for USB hard drives are FAT12, FAT16, FAT32, and XFS.
