Problem Corrective Action
No detection on TX1;
Apple device is in TDM
and all cabling is solid
As mentioned in “Apple Target Disk Mode acquisition
adapters” on page 199, it's possible that the Apple computer
you are attempting to acquire is a newer version with a T2
security chip. TX1 does not currently provide a means of
detecting or unlocking drives from a T2 Apple computer.
TX1 detects two drives
even though only one
Apple computer is
connected
This indicates the presence of two drives internal to the
Apple computer. Certain iMac models have the option of a
small SSD paired with a large HDD. Those two drives can be
configured on the Mac to act independently or as a virtual
Fusion drive setup (one virtual drive that makes use of the
two physical drives). In either configuration, TX1 will show
the two drives as separate drives, each of which can be
acquired independently.
If you are still having trouble detecting your Apple computer in TDM, please contact
OpenText Customer Support to report your issue or ask for further assistance.
6.2.5 Long time to complete locally initiated firmware update
The ability to update TX1's firmware from the unit via any mounted media (local or
network based) has made firmware updates more flexible and convenient. However,
this process can take a long time when used with original/obsolete TX1 SD cards. In
Tableau testing, updating an original TX1 SD card via the user interface took
approximately 13 minutes compared to approximately 2 minutes 30 seconds with a
new model SD card. During the update process, the screen will show a progress bar
to let you know the process is still active, but the bar moves so slowly with the
original (now obsolete) SD cards that it may appear to be hung. Note that there is
nothing wrong with the original SD cards after a local firmware update. Such an
updated card can be used with confidence.
Please be aware of this delay with the original SD cards. Should this lengthy
firmware update time become an issue for you or your organization, please contact
OpenText Customer Support for resolution options.
Note that the original SD cards are easy to identify as they have the Guidance
Software “G” logo in the bottom right corner of the label. New SD cards have the
OpenText logo.
