DATARECOVERYUNION.COM03 mins

External Hard Drive It is important to follow the appropriate steps when disconnecting the hard drive. If the proper procedure is not followed then data may be lost.

In Windows a small icon appears in the system tray (next to the clock) . this is the dismount icon that allows you to safely disconnect hot pluggable devices.

To dismount the drive before removing it follow these steps:

  1. Right click the icon. This give you the options to safely remove each hot plug device attached to the system.
  2. Choose to remove the external drive. Once you click the choice another window will open allowing you to select which device to remove.
  3. Click the Stop button then you will be prompted for confirmation.
  4. Windows OS displays a message when it is safe to turn off the drive.
  5. Once the drive is turned off, disconnect the interface cable.

If the device is busy then the request to stop the device will be rejected. Be sure to close any applications that are using data from the external drive then attempt to stop the device again. Usually the Windows Explorer will be open and will be the application keeping the drive busy.

In Mac OS the drive appears as an icon on the desktop. Before unplugging the drive the drive needs to be dismounted by dragging the drive to the Trash Can. Wait a few seconds after the drive has gone into the Trash Can, once the activity light has gone out you can safely remove the drive. Once the drive is turned off, disconnect the interface cable.

Note: MacOS users should always dismount the drive before shutting down (or powering off) their computer. If the drive is not properly dismounted there is a chance of data loss.

External drive drops offline during data streaming

DATARECOVERYUNION.COM03 mins

External Hard Drive Problem:
External Drive Drops Offline During Streaming

Cause:
During video or other data streaming, the system may unexpectedly disconnect from the external drive, halting the data stream and requiring a reconnect, power cycle or a system restart to allow the drive to be available for use again.

Solution:
Disable System Restore (XP) and Indexing Service (2000 and XP) for the external drive.

Procedure(s)

Disabling System Restore (XP Only):

WARNING: ALL System Restore Points will be deleted when disabling this feature!

  1. Right-click on My Computer and left-click on Properties.
  2. Click the System Restore Tab
  3. Check the box that says, “Turn off System Restore on all drives”
  4. Click “Okay”
  5. It will warn you and ask if you really want to do this, Click “Yes”

Disabling the Indexing Service (XP and 2000):

  1. Open My Computer
  2. Right-click on the External Drive (whatever letter is assigned) and left-click on Properties.
  3. Choose the ‘General’ tab.
  4. Uncheck the Box that says: “Allow Indexing Service to index this disk for fast file searching.”

Additional Information:

Disk Indexing is a feature in Windows 2000 and XP that enables faster and more comprehensive file search functions. By default, Indexing occurs when the system is idle. After a period of inactivity the Indexing Service will resume the cataloguing of files on attached internal and external drives. A streaming operation (such as video) without user input is interpreted as such a period of inactivity and the Indexing Service will resume and begin accessing drives, sometimes causing the external unit to be unexpectedly disconnected from the system.
