=== Kernel Issues with 3rd-party adapters ===
 
−
Many (most?) of the SATA adapters listed on eBay are 3rd-party clones, and the kernel will often limit them to UDMA/33 speeds, with a maximum of 33.3 MB/s.  They are thereby rendered slower than the common IDE adapters.

'''NOTE:''' Using {{bootparm|libata.force|X:80c}} is oft referred to as a "work-around"--the better solution would be to patch the kernel, e.g., [http://bugs.launchpad.net/ubuntu/+bug/195221 Ubuntu Bug #195221].  Then again, this problem has been around at least since [http://www.mail-archive.com/linux-ide@vger.kernel.org/msg14622.html January of 2008]....

Ultrabay Slim SATA HDD Adapter

This is an adapter to connect an additional hard disk drive to the Ultrabay Slim.

Features

  • Takes any ThinkPad SATA 9.5mm thick, 2.5" HDD

Ultrabay Slim SATA HDD adapter

NOTE!
This SATA HDD adapter only works with select ThinkPads as listed below, for other machines with UltraBay Slim, use the PATA base UltraBay Slim HDD Adapter instead.

Part numbers

  • Marketing PN: 40Y8725
  • FRU PN: 26R9246
  • other P/N: 26R9247

Supported with

Unsupported Use

The adapter has a black plastic grommet at the back that restricts its use to the 60 series ThinkPads. Some people have successfully removed this grommet with a pair of channel lock pliers, or sliced it off with a Dremel after which it will fit into older ThinkPads like the T40 series. This works because the adapter actually bridges the SATA HDD to PATA as those older machines have no SATA support. Be aware, some ThinkPad firmware contain a bug which limits PATA speed, see: How to put SATA in old ThinkPads#performance limited to UDMA 2.

This has been tested with the following ThinkPads, although this is obviously not supported!
