The best way to sand drywall is to use a pole sander (manually). You can pick them up for about $20.

This particular machine tends to leave grooves in the drywall compound if you are not familiar with how to use it.

Please help me to understand a faulty motor

If you go on a Bosch factory web site you should be able to enter your model and down load a parts list. From that you will see that the motor drive an eccentric dog that causes the plate to jitterbug. If you kept the original paperwork you will have had this with it. All Bosch units come with warranty and parts list. Look up your nearest Bosch tools agent, see if he'll strip it if you can't and determine what's needed. You may find its easier and more cost effective to shop around online for a special offer and buy a new one. Not very green I know but may be more practical.

Sander doesn't spin

YOUR BALLBEARING where the disk is on mounted is the right bearing that have the problem for shure it is full of dust or completely dry it will not turn anymore SIMPLY TO CONTROL IF YOU MOVE YOUR DISK NOW ON YOUR MACHINE YOUR ARMATURE TURNS DIRECTLY WITH THE DISK thats not good the armature must stand still , replace the ballbearing or remove it and open it with a very little sharp screwdriver on the both sides solvent it out try to turn the bearing carefully until its turns without problems dry it or blow it out with a compressor and if its dry lubricate with ballbearing grease close it again and mount it again

Black & Decker Belt Sander suddenly stopped working.

Probably not.
It may have just had a part break inside, like the on-off switch, or one of the wires to one of the brushes, etc., etc.
I buy these regularly, and they are inexpensive, which also means they are made of inexpensive ( cheap) parts.
It wouldn't hurt to take it apart, knowing it may not be repairable. Sometimes parts are available on-line.
Be blessed.

My porter cable sander starts then stops and now it wont start at all thank you

If it is not the plug in the wall socket being loose, then the most common is the motor contact brushes.

Hand sander stops spinning once placed on item to be sanded

This sander has a brake pad that is supposed to stop the rotation when the sander is not actually in use. It sounds like it's malfunctioning.
The only other thing I can think could be a cause of what you describe is an improperly assembled sanding base. Have you changed out the base, and if so, were you sure to properly align the replaced base on the machine before you tightened the allen screw?
If you're not comfortable disassembling a tool that is still under warranty ( I think it's two years for that one), I would recommend finding a Dewalt service center and taking it in for a factory service call.

Disc pad stops

It could either be that the brushes partially burned I would check to make sure your brushes are in good shape and take it out of the helpers pay ;)
