Problem: The displayed available capacity doesn't seem right.
I just moved a lot of files into the trash from my product. Why isn't this reflected in the displayed available space?
Disk space will not be reclaimed until the file is completely erased. To remove the files forever, empty your
trash.
Why is the volume capacity less than advertised on my storage?
After formatting, the available capacity of a drive will show less than advertised on the box. The difference is
based upon how capacity is viewed by the operating system. For example, a hard drive that can store
500,000,000,000 bytes is divided by 1,000,000,000 to equal 500GB. This is the actual capacity listed on the
manufacturer’s box. The operating system uses slightly different math, dividing 500,000,000,000 by
1,073,741,824 to equal 466GB.
Problem: My product doesn't appear to be mounting on my computer.
Are there other Thunderbolt technology devices connected to the same port?
Disconnect any other Thunderbolt devices and see if the Thunderbolt Series volume appears on the desktop.
Does the icon/Do the icons for the Thunderbolt Series volume(s) appear on the desktop?
The drive icon(s) for the Thunderbolt Series storage should appear on your desktop, as long as the disks are
compatible, are installed correctly, and have been formatted in HFS+ for use with a Mac computer. Please also
confirm that the Finder preference for displaying external disks on the desktop is selected at Finder >
Preferences > General.
Is the Thunderbolt Series enclosure connected to a Mac that supports Thunderbolt technology?
The connection type for Thunderbolt technology on the Mac is the Mini DisplayPort. While earlier Macintosh
computers include one or more Mini DisplayPorts, they are only used to connect one or more monitors. Please
note that legacy Mac computers with Mini DisplayPorts do not support Thunderbolt technology peripherals such
as the LaCie Thunderbolt Series storage.
