NEED HELP, cant find compatible HArd Drive for T400s! (1.8")



I purchased a ThinkPad T400s four years ago and have never been dissapointed until recently.


My harddrive died so I went to Best Buy and purchased a 2.5" HD. Now I find out that only 1.8" HD's are compatible! Is this true?


If so, where can I buy a 1.8" HD? The only Lenovo offers costs $600+ and that is way above my budget! I figure I might as well buy a new laptop with that kind of money.. Please advise!

there are not many 1.8 inch drives on the market.

Try ebay for a second hand one. X-18m may fit the bill.

Amazon seems to list a few.  Search on  1.8" hard drive


I don't personally have any experience with these, and can't verify that they are compatible.  Your machine specs are here: ThinkPad Notebooks; 2005 to present (withdrawn models)


Please verify compatibility yourself.

Concessions had to be made to shrink the chassis vertically.

That said, if you don't need the optical drive, get an UltraBay caddy. Those will take standard 2.5" 9mm drives.

There should be some 1.8" Samsung SSDs in 64GB & 128GB versions floating around. The drive in my T400 is a 1.8" Samsung SSD. Its a little slow for an SSD, but rock solid. Runcore also sells 1.8" drives.

X1 Carbon 3rd Gen Type 20BT i7-5500U, 2560x1440 (non-touch), Win 10 Pro, 8GB RAM, 512 SSD, Intel 7625 WiFi, BT 4.0 | ThinkVision P24q-10 monitor

Search for Intel X-18M. Not the newest or fastest, but plenty good and it will work.
