SC101, mirroring can have an impact on performance, especially when used on shared
drives.

Frequently Asked Questions
I cannot remember the SC101’s administration password.

Reference Manual for the NETGEAR Storage Central SC101
What does the Reset button on the back panel do?
When pressed once, it reboots the SC101 When pressed and held for more than six seconds, it
resets the administrator password to default “password” and detaches all the letter drives. This is
handy in case your PC dies and you need gain access to those private/non-shared drives
previously-attached on that PC.
I installed two Hitachi hard disks into the SC101, they don’t seem to work, why?
Hitachi hard disks come with “Master” by default as the disk jumper settings, you must change
them to “Cable Select” (remember to power off the SC101 before you do that).
You may run into the same problem with disks from other vendors, always make sure you use the
“Cable Select” jumper settings with the SC101.
The SC101 shows the message “No Storage Central device was found”.
Check the following things:
•
Make sure that the DHCP server is up and running. (If the green LED flashes three times
periodically, something is wrong with the DHCP server.)
•
The PC and the SC101 must be connected to the same LAN/sub-network (not across different
routers, for example)
•
•
•
The green power LED should be solid
You must have at least 1 hard disk plugged into the SC101.
ATA5 or older IDE hard disks are not supported (If you plug in an unsupported disk, the green
LED will flash four times periodically)
•
If you upgrade the firmware, or click the reset button, or disconnect and reconnect the CAT5
cable to the SC101, the SC101 will reboot, please wait for about two minute for the reboot to
complete. If you create many drives, it may take some extra seconds to the reboot the
complete.
•
You may be running some personal firewall software on your PC. The SC101 works behind
Windows XP Personal Firewall, but doesn’t work behind firewalls like Trend Micro Personal
Firewall and Norton firewall. Disable the firewall, or configure the firewall to open UDP port
20001.

Reference Manual for the NETGEAR Storage Central SC101
I unplugged the disk from SC101 and plugged it to a PC. Why doesn’t the PC
recognize the disk content?
The data content saved on the Storage Central hard disk is NOT compatible with your personal
computers. You can’t use the IDE hard disk on both your PC and the Storage Central device.
Sometimes I lose the drive letter of the drive. How do I get it back?
Detach the drive and attach it again. If that doesn’t help, reboot your PC (you may also need to
reboot SC101 and the router too) and it will be back.
How do I know whether my hard disk is broken (e.g., gets bad sector)?
The green power LED of the SC101 will blink: If one 200ms blink at 1.5s intervals and continues
that way, disk 1 is bad If two 200 ms blinks at 1.5s intervals and continues that way, disk 2 is bad
The default hard disk is named by the IP address. How do I tell which disk is
which?
In the Wizard mode, the physical size of the disk is shown in the disk list, in the Advanced
Configuration mode, if you move the mouse over to the disk entry, a tool tip box will show up and
tell you the disk information as well.
However, if two disks are of the same physical size, the GUI doesn’t have a way to tell the
difference. What you can do is unplug one disk (power-off the unit first), rename the one disk left
in the device, then re-plug back the second disk and rename it too.
I don’t see those previously-created private (non-shared) drives. What can I do?
If you remove and reinstall the software without being connected to the SC101, or your PC simply
dies/goes away, then you won’t be able to see those drives. What you can do in those cases is to
press and hold the reset button on the back panel for more than six seconds. After the SC101
reboots, you should be able to see those drives in the Advanced Configuration mode’s Available
Drives list and attach them again.
Please note that this reset sequence will reset the administrator password back to default
“password”. You should change it again for security.

Reference Manual for the NETGEAR Storage Central SC101
Can I un-mirror a mirrored drive?
There is currently no option to remove mirroring for a mirrored drive. However, you can simply
power-off the unit and unplug one of the hard disk and power it on. The mirrored drive on the
plugged hard disk becomes a regular drive. After that, power off the unit and plug the second hard
disk back in and power it on, you will get a “broken mirror” drive on that second disk, which you
should delete to recover the storage space.
Why does the administrator password authentication show up sometimes, not all
the time? And why does it show two times sometimes?
The administrator password authentication is required for the following operations:
•
•
•
•
Firmware upgrade
Hard-disk name change
Drive name and password change
Delete an existing drive
For the same Storage Central Manager GUI session, it is authenticated the first time you try to run
one of the operations, after that, the same GUI session won’t need authentication again until you
exit and restart SCM.
The password authentication is done once for each hard disk on which the letter drive is created. In
case of a mirrored drive, it is created on two physical disks and therefore the authentication page
will come up two times, one for each hard disk.
Why doesn’t my old IDE drives show up?
ATA5 or below IDE drives are not supported, you need an ATA6 or above. If you plug in an ATA5
HD, after rebooting, the green power LED will flash four times periodically, to signal that an old
ATA5 or below IDE drive.
I created a shared drive on one PC. Why doesn’t it show up in other PCs?
After creating the shared drive on one PC, it doesn’t automatically show up on other PCs, you need
attach it once from the other PCs. You can use the “Attach drive” function in either the Wizard
Setup mode, or the Advanced Configuration mode to attach the shared drive, or any detached non-
shared drive.

Reference Manual for the NETGEAR Storage Central SC101
I reconnect the CAT5 cable on SC101 to the router, then SCM can’t find SC101, and
my drives get disconnected. Why?
When SC101 detects a cable disconnection and reconnection, it will reboot itself automatically.
Wait about two minutes for the reboot the complete.
The Storage Central Status screen shows more drives than the Manage Drive
screen. Why?
Each time you create a mirrored drive, the SC101 adds two drives, one drive on each hard disk.
Each time you add capacity (i.e., span) to a drive, a new drive is created with the added capacity,
and linked with the original drive. The number of drives shown in the Storage Central Status
screen shows the total number of all those drives, including non-shared drives created on other
PCs, and broken drives too.
The drive creation process failed and I was asked to delete the incomplete drive
and try again. I don’t see that drive in the Storage Central Manager software. How
can I delete it?
Usually, the incomplete drive/broken drive can be seen on the Manage Broken Drive screen and
can be deleted from there.
In very rare cases, the drive was allocated in the SC101 hard disk, but it is not formatted and its
property was not communicated back to the Storage Central Manager, which caused the SCM to
not able to find it.
When this happens, the drive is created unsuccessfully, but it may still take up storage space from
the SC101 hard disk. You should remove it to make the storage space available to other drives. See
Restoring the Default Configuration
This section explains how to restore the factory default configuration settings to the SC101.
one PC is able to attach to a non-shared drive, if that PC goes away, reset is the only way for
another PC to gain access to that drive). Please be assured that the reset process will NOT reset any
drives or the data on the drives.
See “The reset button is located between the Ethernet RJ-45 connector and the power socket.” on
page 2-4 for a description of this button.
