Cannot See SC101/SC101T Partitions on a Computer

Upgrade to the latest version of the firmware and utility: Firmware version 4.22.13 for SC101, Firmware version 1.0.8 for SC101T and SCM version 2.0.23

Once an SC101 (OR SC101T) partition is attached to a computer, it is visible in a file browser on that computer. Sometimes there's a small delay before the computer recognizes it's there and the partition shows. If the partition does not show at all, or if it once showed, but now has disappeared, then read this article.

• In some places a partition — which is one area of a disk which is sectioned off from the rest — is confusingly called a drive with the SC101. For example, in Step 3 below, where the GUI reads "Attach Drive", it really means "Attach Partition".

If a partition has never been seen on a particular computer

1. Click Start > Programs > NETGEAR > Storage Central Manager Utility. (The menu item may read Storage Central Manager Utility / NETGEAR Storage Central Manager Utility / SCM, depending on what version is installed.) Some time will go by before the next screen appears.
2. Ignore the automatic update by selecting the other radio button, clicking Next, then dismissing the popup by clicking No.
3. Select Attach Drive (either in the Wizard mode, or in Advanced Configuration mode) and click Next. Wait till the window displays the drives which are available to the computer, but which have not yet been attached.
4. Click to highlight one of the drives listed under "Select an available drive".
5. Enter the password for the partition/drive. Leave it blank if you didn't set any password (The password in this step is the password for a one particular partition. This is NOT the password for the whole disk, which is defaulted to the word "password".)
6. Click Attach Drive.
7. If you enter the wrong drive password, a message "Incorrect password" appears. Highlight the partition, and reenter the correct password. If you forget the password, you can reset it to blank by clicking Reset Drive Password. If you do this, you are asked for the SC101/SC101T administrative password — be aware that you cannot cancel out of this screen, and if you click Exit, the Wizard will close, and you'll have to repeat the above steps. Once the partition is successfully attached to a computer, it disappears from the list of attachable partitions.
8. On each computer that will access the SC101, repeat the above steps.

If a partition disappears — one that a particular computer could see before

1. Power off the computer.
2. Power off the SC101/SC101T.
3. Power on the SC101/SC101T.
4. Power on the computer.
5. Click Start > Programs > NETGEAR > Storage Central Manager Utility. (The menu item may read SCM, instead, depending on what version is installed.) Some time will go by before the next screen appears.
6. Ignore the automatic update by selecting the other radio button, clicking Next, then dismissing the popup by clicking No.
7. Select Attach drives and click Next. Several minutes later a screen displays showing drives which are available to the computer, but which have not yet been attached.
8. If the partition is listed under "Select an available drive", then it is not attached. Attach it again:
   1. Click to highlight one of the drives listed under "Select an available drive".
   2. Enter the password for the partition/drive. Leave it blank if you didn't set any password (The password in this step is the password for a one particular partition. This is NOT the password for the whole disk, which is defaulted to the word "password".)
   3. Click Attach Drive.
   4. If you enter the wrong drive password, a message "Incorrect password" appears. Highlight the partition, and reenter the correct password. If you forget the password, you can reset it to blank by clicking Reset Drive Password. If you do this, you are asked for the SC101 administrative password — be aware that you cannot cancel out of this screen, and if you click Exit, the Wizard will close, and you'll have to repeat the above steps. Once the partition is successfully attached to a computer, it disappears from the list of attachable partitions.
9. If the partition appears on the Broken Drive screen then the partition is broken (for example, a broken mirror if one disk is removed) and needs to be removed using the "Delete Broken Drive" button on that screen.
10. If the partition still does not show in either the "Manage Drive", "Attach Drive" or "Broken Drive" screens, then there are two methods to resolve it, the first method is easiest and safest.
    • Method 1: Uninstall the SCM, then reinstall it. All partitions will need to be reattached again.
    • Method 2: Alternatively, edit the Windows registry. Don't do this unless you have experience registry editing. Mistakes can cause the operating system to stop working.
    • Microsoft explains the purpose of the registry in this article.
    • It's advised to back up the registry before changing it manually. The process is described in this Microsoft article.
    • NETGEAR IS NOT RESPONSIBLE FOR PROBLEMS CAUSED BY EDITING THE REGISTRY !
    1. Start the registry editor.
    2. Select HKEY_LOCAL_MACHINE\Software\ZNS\Client. There should be multiple sub-entries under Client.
    3. Highlight the sub-entry in the left pane which shows in the right pane the name of the missing partition as "UserDefinedString" and click Delete.
    4. Confirm to remove this key ( Make sure you do not delete the Client key itself, only the sub-key with the missing partition name)
    5. Quit the registry editor.
    6. Reboot the computer. The partition now shows in the "Attach Drive" screen.
    7. Attach the partition again.
