External NTFS drives will work with no problem with Ubuntu. Just plug in and use it.
No. Playstation3 supports only Fat32.
Hi! NTFS file system supports needed options.
ntfs
Any external hard drive that presents itself as a standard USB Mass Storage device should work in Windows ME. This is about 95% of the drives on the market. Note that large hard drives may perform very slowly with the FAT32 file system, and Windows ME does not support NTFS.

NT file system (NTFS)
Since Ubuntu is installed as an ext4 file system (not NTFS as in Windows), there is no need to defragment anything.
The NTFS format is owned and controlled by Microsoft and so is not available as a standard format with the Mac's Disk Utility. There are options such as Paragon's NTFS for Mac OS X but normally this would be used on a secondary external drive rather than reformat the MacBook's hard disc.
Yes, you can. If the external hard drive is formatted using the FAT32 or NTFS file system then you can read it in any windows computer. If you have it formatted as one of the Linux file systems (EXT2, EXT3, JFS, etc.) then just pop in an Ubuntu Live CD into the computer that you want to retrieve the data with and copy it off.
Mac OS X cannot read an NTFS file system without the assistance of a third party program. See the related link below for a list of solutions if it is absolutely necessary to open NTFS file systems using OS X.
Not natively, although there are programs that will allow you to read an NTFS partition.
