    Hi,

    Is it possible to remove the USB removal alert messages...?

    That´ll say the message that pops up if I remove a USB-thumb drive without unmounting it...?

    Not that I know of...and on a Mac all external media (hard drives, flash drives, optical drives, cameras) should be thrown in the Trash (dismounted) before unplugging.

    This is like asking if you can disable the check engine light in your car because it's on and it annoys you.

    The alert is there to tell you not to do what you're doing.

    The message is there AFTER you've done what you've done. In my experience it has never, ever done any harm to a USB Flash Drive or OSX to remove it directly without dismounting it. If it does please, tell me what damage it does - not inconvenience it might cause - from not dismounting first.:cool:

    If you were writing to the USB stick moments before you yank it out, you risk losing data if delayed-write caching was being used and the buffers have not been flushed. Specifically, some or all of the changes may not show up and it may result in corrupting the USB drive's file table.

    It is rare, but I've seen it happen.

    notjustjay is correct. The warning tells you that you a mistake. You may not think that harm has been done, but you are further mistaken. The warning gives you the opportunity to address your error on the spot.

    I have had this experience.

    It does not matter either if we're talking OSX, Windows, Linux whatever. It's a risk that the OP now knows about and can choose to continue to risk his data or do it right. :)

    Dataloss and data corruption. Tested it and I can reproduce it very easily each time. It does harm and you *may* be able to fix it (no guarantee you can).

    I've had my 30 GB iPod classic freeze on me (on the Do Not Disconnect screen) when I've yanked it without ejecting it before (it is not actively syncing when I've done this).

    This is likely not the trend and probably an isolated issue with my iPod. It's happened quite often though. I understand that the iPod is old..

    I have also lost data by pulling out the drive too fast. Best to download a program like unDock (available on the app store... and no, I don't work for them) which lets you unmount all removable drives with a key command.

    ?

    You simply select the volume then:
    - drag it to the trash, or:
    - right click it and select eject, or:
    - press cmd-e

    If you want to eject multiple volumes simply select the ones you want to eject and choose one of the above. You certainly don't need an app for that!

    So, how do we disable this warning? It's annoying, especially with stupid pocket flatbed scanners like the HP Photo Scan 1000, that scans to an internal usb drive.

    ^^ this, but it ain't elegant...

    Or simply do what you're supposed to do: eject the volume before pulling the plug! No need for hacking files...

    Exactly! The warning message is there for a reason, I've lost files when someone pulled a flash drive out of my computer without letting me eject it first.

    The message doesn't really help you after you have pulled the thing out...

    Sure, it is a nice reminder, but the damage may be done.

    Whats so difficult about unmounting it?? or just hitting the eject button on your computer??

    Whats so difficult about a 5sec operation??

    Answer: NO!

    So that means it's a good idea to disable it entirely?

    Methinks that logic is flawed.

    I didnt say I agreed with the OP. Nice assumption.

    But the logic isn't flawed, it simply depends on what purpose you think the message serves. But continue on with your childish rebuttals, that suits you more than thinking it seems.

    FWIW Windows has an option to disable the write cache on some drives so you can just yank them.

    That's a very wrong assumption. The message is a big hint that you should check if the data on your disk is still there and intact. Scan it with disk utility. Not telling you that something may have gone wrong would be unhelpful and rediculous. Now you can check the data instead of finding out at location that the data isn't there or is corrupted. If you need to drive for like an hour or so this makes a very big difference! Without the message you'd have wasted a lot of time.

    I agree with the thread starter. I would like to have an OPTION to disable this alert. I use a thumb drive to exchange files between a Mac and a non-networked Windows machine. It is always the same type of file and of similar size. I know when either machine is done communicating with the drive, and while on a Windows side I can just pull the drive out and walk away, I have to wait until the Mac deigns to release the drive. After a while it gets tired.

    Officially you have to unmount the drive first no matter what OS you're running (yes, that means Windows too!). Windows not warning you with such an alert is a bit of a design flaw, I don't know why they went with it. However, it's not like they don't warn at all, they just hide it very well (like they do with a lot of other stuff).

    Since it is crucial in any OS that you first unmount the volume before ejecting or pulling anything there is no option to disable this. It's like leaving out the buttons for shutting down/starting the computer. You can want, pray, wish, scream, etc. whatever you want, the option isn't there and it never will be there.
