Missing storage on external drive

[Captain Seabiscuit]

Bought a second hand external Western digital HDD label said 365gb but when i got home it will only appear as 298, have i been ripped off or am i not realizing something?

What is the model of your device? Also, how many partitions are on your external HDD?

Hi there Captain Seabiscuit,

Usually, drives offer smaller capacity than indicated on the drive label. That comes from the different measurement standards(decimal/binary): http://products.wdc.com/support/kb.ashx?id=UvyS52
Then, I guess your drive should have 320 GB on the label.
If this is not the case, it may be a good idea to provide a screenshot of your disk management.

You can test the drive with WD's DLG tool as well(both short and extended tests): http://products.wdc.com/support/kb.ashx?id=RQkZ51

Let me know how this goes,
