  • Page 3: Viewing And Accessing Drives

    The SC101 may drop off when operating at the extreme limits of wireless range. NETGEAR may release firmware shortly which needs even less throughput. Windows Disk Management Unallocated Partitions This section explains what to do if you have created partitions with the SC101, but they show the unallocated partition attribute in Windows Disk Manager.
  • Page 4 The blue volume above represents a known working partition and the black volume represents the non-working partition that the following steps will fix. Right click the red circle, select Initialize Disk, and click Next to continue. Right click the black unallocated portion of your volume. Select New Partition and click Next.
  • Page 5 5. Select Primary partition and click next. Leave Partition size in MB at the maximum or default value.
  • Page 6 Select the default “Assign the following drive letter” and click next. VERY IMPORTANT – DO NOT FORMAT THIS PARTITION should be selected. Formatting the partition from Disk Manager will result in loss of user data. STOP! Do not click the Finish button until you read this screen’s selected setting’s output and have confirmed that your File System reports None.

  • Page 7: Cannot See Partition (Old Firmware Problem)

    If your File System reports None, then click Finish. Once you have selected Finish, your partition should change from black to blue in the Disk Management Utility. Example: Seagate1 and Seagate2 are both SC101 volumes and do not list a file system type under the column titled “File System”.

  • Page 8: If A Partition Has Never Been Seen On A Particular Computer

    GUI reads "Attach Drive", it really means "Attach Partition". If a partition has never been seen on a particular computer 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.

    Hard drives are on the Drive Compatibility List. Hard Drives must be ATA6 or above (Parallel ATA) and configured as “Cable Select” (CS). The Power LED light must light up solid green. The DHCP Server must be present. Use a wired PC to configure/modify the SC101 (see diagram). Also check the following: Do not use a drive that was formatted on a PC.

  • Page 20: About The Sc101

    SC101 and Heat Generation The SC101 is tested by NETGEAR to make sure that it operates in safe temperature limits. Computer owners are used to touching the outside case of a computer which is near room temperature, however it is not necessary for electronic devices to be at room temperature to operate safely.

  • Page 21: How Does Heat Affect The Storage Central Performance

    Reading and writing to the SC101 from a high performance computer In the best conditions, the fastest read time is 7 MB / second, and the fastest write time is 5 MB / second. The San File System used by NETGEAR has the strongest advantages with read/write, bandwidth-intensive applications.

  • Page 22: Self-Certifying File System (Sfs)

    Self-certifying File System (SFS) To reduce request fragmentation for large requests, Self-certifying File System (SFS) bypasses the Windows buffer cache and tries to make one request for the entire amount of data. The SFS accesses hard disks by addressing entire extents, which are flexibly-sized groups of blocks.

    A black and white window pops up, with a blinking cursor after the prompt (the prompt ends with a greater than sign ">"). Type cd c:\Program Files\NETGEAR\SC101* This changes the directory. It also changes the prompt, so that you can see what directory you are in.
  • Page 24 PARTITION Unique network identifier for each partition. (This is the same value that appears in the "ut getpart" command as UNIQUE NAME.) LABEL What each partition is named. In this example, the first partition is "test20gb" IP ADDR the IP address of each partition on your network. SIZE(M) size in MB of each partition.

  • Page 25: Command: Ut_Full Getpart

    This involves using a special SC101 command called ut_full. NOTE: This is the only situation NETGEAR recommends using this utility. Do not use it to change attributes of partitions that are working correctly. This might destroy data! You will need to use the ut_full getpart, ut_full listall, and ut_full newattri commands.
  • Page 26 Type Start > Run, and type cmd in the pop-up window. Click OK to open a CLI window. Type cd program files\netgear\sc101* (The last character is a star.) This changes the CLI to the directory where you placed the ut_full.exe file.
  • Page 27 Close the CLI window by typing exit. Now, return to what you were doing before seeing the error. (Probably, using the SCM utility. In the SCM, select a partition, and click Attach Drive.) If you bring up the SCM, the partition now shows normally. Disabling the Promise drivers in order to install the SCM Utility Use this fix if during installation of SC101 SCM utility, there is either a blue screen, memory dump, or the computer crashes or hangs.

  • Page 28: Removing An Unusable Drive With Ut.exe

    1. Open a DOS window, go to that folder and type “ut” to see the available commands. Type Start > Run > cmd. A CLI window opens. Type cd C:\Program Files\NETGEAR\SC101 Manager Utility. Type ut. In case you need them on another occasion, this lists all the commands you can run.
  • Page 29 Type: SFSExtract SINGLE <drive> <target> Where <drive> is the non-accessible SC101 partition drive letter showing up in Windows Explorer, and <target> is where you want to copy the data to. Note that the <target> (or another drive) MUST have more available storage space than the total data size on the SC101 “<drive>”.
