## Is Maxtor messing with his costumers pocket?

A few days ago, my aunt ask me to buy her an external portable hard drive for backups.

She’s an accounting freelancer and works mainly in a laptop computer. To prevent loosing data she makes periodical accounting data backups.

I ask her to see the backup data size and is small … very small, so … I decide to buy her a small capacity 2,5´´ external hard drive.

Here is the chosen one: [more]

As you can see, I choose a 80GB capacity drive.

I decided to try it and see if it is working fine.

The first thing I checked was the disk capacity.

Here is what I found:

The external disk properties tell me that disk capacity was 74,5 GB.

I simply plug it to my laptop and do nothing more … so I can only think that Maxtor is messing with his costumers pocket.

I know that many people don’t know that bytes aren’t metric like numbers.

• 1K byte = 1024 byte not 1000 byte

So, you can say that 80.023.715.840 potatoes are 80G potatoes but when referring to bytes you must have 85.899.345.920 byte to say you have 80G byte.

If you make a simple calculation you will find that customers are getting 6,875%(5,5 GB) less storage capacity than what they paid for.

Naturally, if Maxtor keep is calculus rule the same for larger capacity disks then customers will get even less percent than my case.

Before you buy an external hard drive ask the vendor to show you the drive in action and check it’s real capacity.

## Advanced MooTree – Concept Proof

This is a sample I made for a recent project. The tree is based on Moro script with a few changes and a major improvement: a tools menu that enables add and remove actions directly on node.

Beside the tools menu its now possible to:

• prevent a node from being dragged: drag:false
• prevent a node from being a drop target: drop:false
• prevent a node from being modified(keep structure intact): lock:true

The tools menu is render based in those flags:

• if the node.parent is locked(lock:true) then the node is not electable for drag or for remove and the tools menu is empty
• if the node is locked(lock:true) then isn't possible to add more nodes(either folder or file)

Remember this is just a concept proof, not a final release, but even so i believe it could be usefull.
