Improperly Removing External Hard Drive(s)
Caution
: To prevent loss of data, save your work and close associated applications
before removing the external hard drive (applications need to be closed since they may
keep temporary working files open on the external hard drive). Always unmount the volumes
(eject or drag the volumes to trash) associated with an external hard drive before removing it.
If you do not properly unmount volumes before removing the associated hard drive(s), a
“Device Removal” dialog box will appear (See Figure 21). This dialog box shows up as a
reminder to unmount volumes properly before disconnecting or removing external hard
drives. Failure to properly unmount volumes before disconnecting external hard drives may
result in lost data.
