I noticed a Advt (there were also other similar adds) on ebay which says:
2nd SATA HDD Hard Drive Caddy Adapter for IBM ThinkPad T4 Series T40 T41 T42 T43

Is it real or a illusion?.My T41 only has a pata interface for a IDE HD.How Do i find out about the dvd interface?.
My T41 mode is 2374-7FU

The Caddy will have a PATA connector for allowing it to plug into the UltraBay and then an internal SATA connector for adding a SATA HDD into the Caddy itself - it's pretty common stuff these days.

EDIT: The basic technical specs for your model of ThinkPad is listed below but also you can find out more information about your model series via http://www.thinkwiki.org/wiki/Category:T41 as well.
