Hey, guys , can you tell me the best & safest way to use USB Flash Drives ?
I use slack 10.
my USB fdrive has a small light , OFF when it's ready to use, ON when it's not ready / already stopped ( in Windows)
In Linux, I can use it, I can mount , and umount it.
But after I umount, the light is still OFF, meaning it's not safe to pull it out.
I poweroff the system, and it's ON.
What if I don't want to poweroff it, but I want to unplug my fdrive?
any suggestion? or maybe it's safe already if I have umount ? can i pull it out after that? it is safe? thx....

Once you unmount or eject the drive, it is safe to remove. To remount it, you may HAVE to unplug and replug it, which activates hotplug and makes it ready again. Unmounting 'flushes' the drive, finishing any data transfers before unmounting.

Hi,
You can also use the "sync" command to actually force the flushing of data to disk, unmounting the drive does the same thing also.

In linux when you unmount a usb device you do not actually switch it off. Power is still being diverted to it, makes it ready to be mounted again when u need it.

yeah, that's what I meant. Is it safe to unplug on a condition like that?

In windows, I Stopped the device, and the light indicator turns ON. ( my device's light turns ON when it's "OFF")
in Linux, I umount the device , but the light still OFF.
I wonder whether it's safe or not to unplug .
??

once it's unmounted it's safe to unplug it.

gee, thx for the clarification
I'm happy to hear that.
