If it's any help I'd urge you not to use the "Quick Format" option when setting up new drives as this always leads to trouble.
Quick Formatting is always recommended, especially if you have over 4GB partitions.
Some format commands don't support long partitions and they wrap around at some point. Not good. Quick Format always works.
If the disk is knackered, then a full format won't help either.. Time to plug it in a PC, fill it with FAT partitions and run Spinrite to see if that can liven it up a bit.
Bad sectors have a tendency to multiply on a disk. Even after spinrite, I wouldn't trust the disk after that.
