Esata enclosures vs. host comp's OS
Looking at Esata enclosures for external backup. I don't understand why
they say that they are supported on say up to XP but not Win7 or Linux? See the following: http://www.newegg.com/Product/Produc...-167-_-Product This one says Linux is supported assuming a new enough kernal but also doesn't mention W7: http://www.newegg.com/Product/Produc...-179-_-Product Why isn't W7 mentioned and in fact on one of the reviews at Newegg a purchaser explicitly says that anything above XP isn't supported. I mean, SATA is SATA, either the host comp's OS supports SATA or it doesn't. What is the deal here? Does the enclosure itself need an operating system? Thanks, John |

It works with Vista and Win 7. The specs say XP and above, meaning Vista, and Win 7, and probably even Win 8, when it's released. If your computer has an eSATA connector, the Vantec is the better bet as it will be faster than USB. The Rosewill is USB only. Also, eSATA is bootable, and the connection from your computer to the drive is straight through, without any intervening controller. The Vantec's internal controller is for the USB to SATA conversion. That means it can use any OS you motherboard supports, with the drive formatted accordingly. If your computer doesn't have eSATA, but has unused internal SATA connectors, you can get a cable to connect from SATA to eSATA connectors on a back slot cover. |

See the following: http://www.newegg.com/Product/Produc...-167-_-Product If you want to see the actual manufacturer's specifications on a product then click in the "Manufacturer Product Page" link in Newegg's details page. Notice what operating systems the *manufacturer* states for that product. |

I mean, SATA is SATA, either the host comp's OS supports SATA or it doesn't. What is the deal here? Does the enclosure itself need an operating system? Thanks, John The components of ESATA a 1) SATA - OSes have had SATA drivers, or the ability to accept a manufacturer's SATA driver, for some time. Both Vista and Windows 7, have their own generic drivers, or in some cases, you can install a driver for the hardware. If the OS is an old one, if the hardware has a "compatibility" mode, you can still use your drive. So in fact, there are plenty of options here. Even an IDE to SATA adapter, and a SATA to ESATA cable, might just work. 2) Enhanced transmit and receive levels on the interfaces. This allows 2 meter cables, instead of 1 meter cables. If you're having trouble, switch to a shorter cable. This is seldom an issue, so I include this point, as a means of distinguishing SATA from ESATA. A tiny difference in electrical levels, so the cable could be made longer and still work. 3) Hot swap. The driver for the chip doing the ESATA, needs hot swap capability if you want the disk to be mounted the instant it is plugged in. If, for any reason, hot swap is not working, you can plug in and turn on the drive, before the OS boots, and then you can use it. So a lack of hot swap is not the end of the world. Hot swap is available with an AHCI driver, but if that is too hard to arrange when needed, you can also ignore the requirement, and just plug in and start the ESATA drive, before the OS starts to boot. In the grand scheme of things, you have little to worry about. Maybe if you have really crappy cabling or adapter plates, it'll put up a fight. If the computer case comes with an ESATA port on the front, computer case manufacturers aren't exactly electrical engineering graduates, and they'll gladly put defective connection schemes on the front of your computer. This applies to those $50 computer cases you buy off Newegg, to build a home computer with. If you're buying a Dell/HP/Acer/Gateway or the like, they've probably tested the front connector at least once. It's only home builders that have to worry. With SATA cabling, it's not a good idea to bend the cable until it becomes kinked. Damaging the insulation, can upset the impedance of the cable. A slight background error rate may result. If you have problems with a SATA setup, a cable swap may fix it. Paul |

Paul The case is a new Antec Sonata III 500, you and a few others helped me select parts for a new XP build in late December, early January of this year. The front mounted Esata port is connected internally directly to a SATA block on the motherboard (no kinks ) so hopefully the hardware is current enough to be satisfactory. My OS if you check my sent from info is quickly becoming Linux Mint (Julia 10, x686 64 bit). It's a refreshing change from Microsoft but a steep learning curve. Hot swapping is of no interest, the enclosure is strictly for back up purposes. I have read (first hand user tests) that Esata is roughly 3X faster than USB2 in the real world and the reason I am interested. I value your opinion and ask: What do you think of the first selection above? Any better suggestions? Thanks, John |

Hot swap is of no interest and I have read that Esata is in the range of 3X faster than USB2. The motherboard in this comp supports USB3 but I haven't seen any USB3 hardware and don't know if it would beat Esata 'in the real world'. So barring a better price point I probably should go with the Vantec. The unit needs to support both M$ and Linux for backups and possibly act as a transfer unit from/to workstation/laptop in the near future. Both Os's (XP and Linux) have no problems with SATA or USB. Thanks for your input, John |

I've found this to be the case with Asus MBs using both JMicron and Marvell eSATA controllers. |

I've found this to be the case with Asus MBs using both JMicron and Marvell eSATA controllers. That is good to know. The work station is a new (home build first of the year) with Asus MB running both XP pro and Linux Mint 10 with USB2 & 3 as well as Esata. My wife's laptop is an older Dell running XP pro. I need the unit to be able to back up both and the Dell doesn't have an Esata port that I am aware of ... but it does have a lot of ports ... so I guess I should have a look! In any event the Dell definitely has USB2 so given the Dell's age (about 3 to 4 years) both modes will probably be needed. Thanks, John |
