Solve : 'Safe' to remove hardware?? |
|
Answer» What does Windows mean by "it's now 'safe' to remove hardware", when you are going to unplug a USB removable pen drive?http://www.tomshardware.com/forum/236841-31-safely-remove-hardware This is probably the best explaination I've read..smartdrv /c, anybody? Ejecting a USB pen drive forces all the write-cached data to be flushed to the drive, and also removes it from the system. Personally I just disable write-caching for all my external drives and unplug them as long as I'm not writing or reading from them.What do you mean 'flushed to the drive'? What is the problem by just snapping the drive out of the USB port without 'safely' removing? =) I also read that in XP, if you unplug and replug the drive too many times consequently, XP will mess up and won't REMEMBER the actual status of the USB device plugged in. LOL! Meanwhile I'll read EEVIAC's link. ^^It means that the device is not powered and you can remove it.Quote from: neelchauhan on April 14, 2010, 10:42:13 AM It means that the device is not powered and you can remove it. Removing/ejecting the device does not cut the power from it. It just stops any reading or writing to the device selected.Quote from: Accessless on April 14, 2010, 02:34:23 PM Removing/ejecting the device does not cut the power from it. It just stops any reading or writing to the device selected. Sorry gibberish moment. Translation: Using the 'safely remove hardware' function does not stop the connected USB device from receiving power from the USB port. It only stops any data transfers EITHER from or to the device to prevent file damage or loss.I understood the meaning REALLY you only eject/stop storage devices, simply because there could be data that windows is HOLDING onto in RAM, waiting for an idle time to write it to the disk.The way I ORIGINALLY read it I actually thought that he was saying the device was 'Magically' getting power through the 'ether' after it was unplugged I just couldn't figure out a way to say it at the time without sounding rude. |
