HP Dc7900 Using eSATA on HP Compaq dc7900 Business PCs - Page 10

Figure 7 eSATA hard drive connecting to the eSATA bracket port Limitations eSATA hot-plugging is available only with BIOS and operating system support. eSATA hot-plugging is not possible in an operating system without an AHCI driver that supports hot-plugging such as DOS, Windows 9x, Windows NT4.0, and older versions of Linux. The system BIOS cannot determine if an eSATA device is SATA or eSATA if it is plugged into the wrong port on the system board. Therefore, all eSATA devices that are plugged into a SATA (non-black colored) port will be treated as SATA devices and will not support hot-plugging. © 2008 Hewlett-Packard Development Company, L.P.
