Seagate External Expansion HDD
Just bought one of these. It comes with its own power supply and has
USB 2.0 connection. Works great. Does anyone know if I have to safe-remove and disconnect it from the PC each time I shut down ? Can't seem to find any info on the Seagate site about this. Thanks in advance. |

Sorry. It is a "Seagate Expansion External Drive". Model ST305004EXD101-RK

Could you mention the exact part number or product name ? It might be easier to find info with a name to use. Paul http://www.seagate.com/docs/pdf/data...xt_desktop.pdf The documentation claims it has "Built-in power management", so that makes it more likely to spin down any time you haven't accessed it in a while. It could spin down on you, even while the OS is still running. If you left your computer running all the time, there might be good reason to "Safely Remove" then remove power from the device. The advantage there, would be preventing nuisance spinups of the device. Sometimes, if the OS probes the device at regular intervals, you can get a lot of spinup/spindown cycles, which isn't good for the loading ramp and head retraction. A drive is rated for a minimum of 50,000 of those cycles, but if an aggressive timer is involved, you can burn up a lot of cycles in a day. But in terms of a power down cycle of the computer, the OS should flush any caches before closing down. The device should then be as ready as possible. Then, any activity timer in the drive itself, should trigger spindown soon after. If you had a product which didn't have an activity timer, and continued to spin even when the OS wasn't running, then I'd follow your suggestion, of doing something to prevent that. You could use "Safely Remove", followed by power off, before the OS was shut down. Or just power the device off, after the OS was shut down. Paul |

The reason you can't find any info regarding that is that like all USB
devices disconnection is is not necessary. Peter Green wrote: Just bought one of these. It comes with its own power supply and has USB 2.0 connection. Works great.

Can't seem to find any info on the Seagate site about this. Thanks in advance. The reason for the "safely remove" feature is that if you have enabled write caching on a detachable writable device (IIRC, write caching is disabled by default in Win XP for removable devices), you might lose data if you just yank the cable out. When you click "safely remove," you force the cache to write to the device and empty. A normal shutdown sequence should do the same, so you need not bother going through the extra manual step. -- Lem Apollo 11 - 40 years ago: http://www.nasa.gov/mission_pages/ap...0th/index.html |
