(9) FAQs
Q: Can I use my drive with bus power only?
A: Yes, in the majority of cases bus power is adequate. However,
USB 2.0 ports may not have enough power for a higher-capacity
SSD version (480GB or more). When using a U32 Shadow SSD with a
USB 2.0 port, we recommend using a USB Y-Cable which can be found
at the following link:
Q: Why does my computer show that the external drive
has less capacity than advertised?
A: In the drive industry the partitioned size will be less than the
printed capacity on the label. This is due to the fact that computers
calculate capacity based on a binary (base 2) method, where
1GB = 1024 MB. The drive industry calculates using a decimal
method, where 1GB = 1000 MB. This is why the two dierent industries
will report dierent capacities for the same drive.
