They should only be used as a last resort.
The problem is that they are a break in the cable. At the extremely high data rates for eSata, this causes signal reflection and data errors. If you do have to use an eSata bracket, you may need to reconfigure that SATA port to only use 1.5 GB; I hear that with that setting it is usually reliable. But what you really want is to have a single uninterrupted cable going directly from the port to the hard disk. Fortunately, you can buy eSATA PCI cards for around $30 nowadays. One pitfall: make sure that it actually says "eSATA". Many manufacturers are cutting corners and put a cheaper internal SATA connector on the external bracket. That's actually illegal (can get you in trouble with the FCC for radio interference). Worse - at first glance, the two connectors look the same, but they actually have different shapes (SATA is L-shaped, eSATA is I shaped). So if you have trouble plugging it in, you probably have the wrong connector. -- Kevin Keane Owner The NetTech Find the Uncommon: Expert Solutions for a Network You Never Have to Think About Office: 866-642-7116 http://www.4nettech.com This e-mail and attachments, if any, may contain confidential and/or proprietary information.
