The adapter contains a PATA to SATA bridge chip, which means that although the disk is SATA it connects as a PATA (IDE) device.
 
 
 
If connected at boot time, the drive is normally located at {{path|/dev/sdb}}

The adapter has a black plastic grommet at the back that restricts its use to the 60 series ThinkPads.

=== Poor performance with 3rd-party adapters ===
 
Many (most?) of the SATA adapters listed on eBay are 3rd-party clones, whose poor build quality limits them to UDMA/33 speeds. They are therefore slower than the common IDE adapters, and especially unsuitable for SSD use.

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

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!
