Overview
The adapter has a black plastic grommet located at the back that restricts its use to the x6x series ThinkPads. Some have successfully removed this grommet with a pair of channel lock pliers, or sliced it off with a Dremel to fit into older ThinkPads like the T40 series. This works because the adapter has a matching connector that fits into the Ultrabay Slim in the T40 series ThinkPads.
Part numbers
Branded as the ThinkPad Serial ATA Hard Drive Bay Adapter
- 45J7901 (45J7902), 26R9246 (26R9247)
Linux support
If connected at boot time, the drive is normally /dev/sdb.
Third-party clones may use other bridge chips, e.g., Sunplus SPIF223A. Some might not be configured correctly thus producing a kernel warning "limited to UDMA/33 due to 40-wire cable" and working slower than necessary. This can be overridden by the libata.force
kernel parameter (e.g., libata.force=short40c
).
