Duda con eSATA

Buenas


Una pregunta rapida: los esata no son plug and play?? Tengo que tener el PC apagado cuando enchufo un esata para que me lo reconozca en Windows cuando lo enciendo??


Gracias
Por primera vez en años la wiki no tiene la respuesta, pero el oráculo dice que:

"Yes, unless AHCI is enabled. I believe Vista loads the AHCI driver, but it must be enabled in the BIOS.
I have
heard you can plug the drive in, do a scan for hardware changes, and it will enable the drive to show as removable device."

"What you have to worry about re. connecting/disconnecting eSATA is the drive power. Drive must be self-powered (and powered up first), or a SATA power connector (or other specially designed connector) must be used to connect to live power (called hot-plugging) as they connect the ground lines solidly before the voltage lines connect - if the power is OFF prior to connecting then the connector doesn't matter. All the SATA data connectors do the same - ground lines are always connected first. That is mainly why PATA drives aren't suited for hot-plugging. But some mobile drive racks equip them for it.

Then you have the problem of true eSATA and regular SATA connectors. True eSATA connectors have a straight tongue inside the male connection while regular SATA connector tongues have a hook on the end. True eSATA supporting controllers also support higher signal currents to allow for longer cabling. So, if your controller does not truly support eSATA, keep your total cable length (mobo to drive) within spec for standard SATA.

I don't have a lot of experience with eSATA, but I do have a notebook drive enclosure that can work with both normal SATA (internally in a drive adapter bracket) and eSATA externally (it's the Silverstone MS05) with an Hitachi 5k160 in it. But I have thought about and researched SATA and eSATA quite a bit. I finally got it partitioned as an internally connected drive using the Ranish partitioning software which has a confusing interface until you figure it out, but works better than the commercial partitioner I tried to use (Partition Commander 9) earlier. The latest version of the Ultimate Boot CD for DOS- http://www.ultimatebootcd.com/ -makes it easy to have a lot of tools handy - and should be in everyone's software tool kit. But your drive may have come pre-partitioned and formatted - its documentation should tell you. AFAIK, the other tips offered above should hold true as well."

Gracias. Luego hare pruebas en casa.
Me ha sorprendido la falta de información al respecto. Yo suponía que los eSATA serían plug&play por defecto, pero al parecer depende (demasiado) de los controladores del SO y compatibilidad con la propia placa, aunque cuente con puertos eSATA.

No se porque sigo sorprendiéndome de que salgan al mercado tecnologías y dispositivos a medio desarrollar y nos los vendan como lo más.
