I've inserted a dvd into slot...doesn't show up in Finder,(DVD is checked in Finder Preferences), and won't eject! Tried to plastic card trick- no luck. Disk spinning in there but won't come out. I have tried holding the right click button upon restart, eject button and holding PC upside down. Disk still spinning but not ejecting!

I have a DVD I was trying to rip, and handbrake froze up when scanning it.  I tried to eject the DVD by dragging and dropping it to the trash, which trashed the icon, but didn't eject the DVD.  I then forced Handbrake to quit, but without an icon on my desktop to select, how can I eject the DVD?

I have a friend who wants to sell their computer, but obviously all personal information and software that it is on it needs to be removed before doing so.  Usually I would format and reinstall it, but I cannot easily get hold of the required XP DVDs and I'm not 100% sure the serial number is stuck on the case as usual so getting hold of it will probably require more effort than I'm prepared to spend.  So, what's the best and quickest way to remove and uninstall everything from the PC without reinstalling it?   Thanks.  EDITS: I'm looking to remove things like Internet History and all installed programs, too. I know how to remove the history and each individual program, but that could take hours.  The machine is not branded and therefore there is no website I can go to download recovery software. There is no recovery partition on the computer and I'm not aware of any recovery DVDs for it either. I can only assume it was installed from a retail copy, and therefore there is no way to recover it to factory settings.  It needs to have XP installed, not any distribution of Linux. Like most average people, the person getting the computer will not understand what to do with a computer that doesn't have Windows installed, and software like Office does not work on Linux either.  Buying another licence is not really an option either. She has just brought a laptop to replace the computer, so buying another licence for a computer that she's getting rid of doesn't really make sense.  Thanks for all the help so far!

Is it necessary or recommended practice to eject external drives before logging out, restarting, or shutting down? (The drives are not being unplugged.)  BTW, I am aware that I need to eject my external drives before unplugging them, I just don't know if it's necessary when logging out or shutting down. It seems to me this should be obvious, but I can't find an explicit answer to this question anywhere. I am interested in answers for Snow Leopard, Lion &amp; Mountain Lion OS versions, as I have 2 machines, one with Snow Leopard, the other with Lion, &amp; I'll soon be upgrading Lion to Mountain Lion.

So, when I used the priority drivers, the suspend worked normal. But the official drivers works better, so I installed the official driver. Then suspend won't work.  Should I change any text/documants to make it work? Any solution will be aprreciated, thanks you all!

I'm trying to install a newer version on a nettop (Acer Aspire Revo) that is running an older version. I have an external DVD drive that appears to be booting up ok, but when I get to the "Install Ubuntu" page, the display just goes off! The DVD drive still wizzes around for a bit and then nothing!  Any ideas?

Computer was humming away happily.  It had downloaded a kernel update eariler in the week and been asking for a reboot since.  This morning I relented.  When the computer powered back up it made a loud repeated clicking noise which I tracked down to my hard drive by opening the cover.  Since then I can't boot the computer - it keeps failing out to netboot (which goes nowhere).  Based on a quick google I think the disk is history.  Does anyone know of a way to recover the disk?  I realise I'm probably SOL but it's worth asking.   Edit  Thanks for the answers.  All very interesting and informative.  Nothing on the drive is worth the cost of a professional recovery service and my backups cover the important bits anyway.  I was just hopeful that I might be able to avoid the nuissance of a rebuild on a new disk.

I have this external (USB) drive that can't seem to be disconnected correctly.  Whenever I eject the drive, it won't disappear from Disk Utility.  Afterwards when the drive gets re-connected again, it cannot be mounted. At this stage, I would need to reboot the Mac to get the drive to mount again.    Ejecting from the Terminal via diskutil eject /dev/disk2 returns a Disk /dev/disk2 ejected message and unmounts the disk.  However the disk still shows up both in Disk Utility and diskutil list.   Furthermore even after the USB cable is disconnected, the disk still shows in both Disk Utility lists — GUI and command line.   How can I solve this?  OS: macOS Mojave 10.14.1 (18B75)

From a Windows workstation when I delete files over the network (e.g. a file share, server disk, etc) those files are never put into a trash can, either on my Windows workstation or on the server - they're instantly and permanently deleted. This has always sucked IMHO.  Is there a software that, in this scenario, puts the files into a trash can somewhere for easy undelete?  Maybe a Windows policy change, registry setting value, software utility, etc ?   -- Looking for a specific solution instead of general "Hey look into this, or try this". I'm convinced somebody has already solved this and can explain it. Thanks.

Okay, I apologize if there are similar threads... but I've scoured the internet and never have I run across a helpful answer. So I'll ask here...   I have an old laptop, an Acer Aspire 5515... It was running Vista and was taking 5-10 seconds to just do anything, even as simple as opening a folder. So I decided to install a windows-user-friendly version of Linux - something I've wanted to try for a long time. I ended up settling on Kubuntu because I read somewhere that it's medium-light weight, and good for people used to running windows, after all, I can always replace it with something different later on.   I went to the ubuntu site itself and downloaded  "kubuntu-16.04.1-desktop-am64"  Then the problems started flowing in. Some of it user error I admit... first the CD I got wasn't big enough, then I forgot you can't copy past an iso file, then I couldn't get the Acer to boot from cd drive  Eventually, I fixed these... I burnt the iso image right, used a larger DVD, and changed the bios to boot from the cd. I went to try to just 'try' Kubuntu but that just wasn't working very well, so I just went and tried to go ahead and replace the OS. I knew it would kill everything on the Vista, but I already transferred the files I wanted to keep and the computer was unusable as it was, so I figured why not.   I went through with trying to do the installation, and the first time got to about 80% when I got the Errno 5 Input/Output Error  Alright then... it said something about heat so I placed the computer on a low running box fan as a make shift computer fan (It was getting hot anyway), and I tried again. Made it to about the mid-60s and got the same error.   This time, I went and I double checked the iso... it's indeed the most recent one on the Ubuntu site, and then I used winMd5sum, which says the checksum is correct. I then got another disk and downloaded imgBurn and burnt a new disk at the lowest possible speed (tried for 1x, but it did 2x).   Tried again and it still pulled the same error around the same spot.  So this time at the bootup screen I pressed shift and chose Check for Defects, it returned with Errors found in 1 file  The memtest86 says no errors.  So I'm assuming that means there's a problem with the CD/iso? The check sum was supposedly correct and it was burnt on the lowest possible burn with trusted software. Also, the cd drive works just fine and the disk itself is brand new without a scuff on it.  I'm pretty stumped what to do. I'm going to try to find a cheap flash drive at the dollar store or something to try to boot from USB, but if there is any troubleshooting I could do to get this to work without having to spend money I can't really afford, that'd be really helpful.   As it stands I have a nearly 10-year-old computer with no OS whatsoever on it because the windows section is all deleted, but the Ubuntu section is not fully installed.

Is there a way to mount back a USB stick that is once ejected, without physically detaching it and then plugging it in?  It was a live-usb of Linux Mint 14 in it, if it helps.

In Windows you have a C-drive. Everything labeled beyond that is with the following letter.   So your second drive is D, your DVD is E and if you put in a USB stick it becomes F and the following drive G. And so on and so forth.  But then, what and where are A and B-drives?

, I'm starting to believe it is not active.  Last night I started up Task Manager and I see 2 disks - Disk 0 (C:) and Disk 1.    Disk 0 appears to be active -    Disk 1 appears to be not active.  It's been this way for at least 3 hours of active use, both Metro and Desktop use.   This is supposed to be the Solid State part of my Hybrid Drive, but it doesn't seem to be doing anything, at least not from the perspective of the Task Manager tool.  Does anyone know of any additional tools that I could you for analysis or do you know if there is some way to activate this part of the drive?  Thank you in advance!

I am in a situation where I cannot use Magical Jelly Bean Product Key Finder since the hard drive has failed on a particular system from HP.  Sadly HP will only sell restore discs and I don't have the luxury of waiting a few days for these to arrive.  I do have a retail disc from another system and have read that a retail copy of Windows 8 (not 8.1) will extract the OEM key from the BIOS in such cases.  Is this indeed the truth?

I searched a lot about this online and couldn't find a solution, I turned off fast startup as many answers have suggested. But it didn't work ,  The problem happened after I connected a secondary hard drive to my laptop removing the dvd drive , whenever I remove the secondary hard drive , above processes act normal. I have a SSD as my primary drive , the problem happens only when the secondary drive is connected , I desperately need a solution since this is killing my computer.

Friend of mine dropped a HDD on the floor and every since the HDD won't mount when connected. It just makes this spinning noise inside for about two rounds and then it goes quiet. Obviously, he wants to salvage the data but I said to him I'll see what I can do knowing the chance of recovery is pretty slim with HDD that won't mount. Was I right about this ? Is there anything I can try I may not know about ? I tried to run gparted on it as I know gparted can detect disks that aren't mounted but connected. But no luck.

Sometimes, a volume refuses to eject because some program is using them.  Sadly, Finder doesn't give the identity nor gives a way to solve the problem.  So, how do you solve this problem in a clean way, without using a terminal ?  Using the terminal, I may find a way to eject it, but it's not reliable.  sudo lsof | grep volumeName certainly gives some information, but I don't feel like killing random processes in order to unmount a volume. Also, not everybody is willing to run command in a terminal.  I also don't want to force eject the volume. I think we shouldn't have to force the ejection when we didn't initially run the program that locks the volume.  Processes that are frequently involved are: mds and notifyd.  Killing mds does not guarantee that the ejection of the volume will be possible. mds process is respawned after getting killed, and continues preventing the ejection of the drive.  I also noticed that mds can be running and using files, and still not preventing the ejection of the volume, so I'm not even sure that it's mds fault.

Been running El Capitan since it was officially released. Updated to 10.11.4 a few days ago. I have a WD Elements USB 3.0 drive connected to my Mac mini (directly to the rear ports, not via a hub). Ever since the update to 10.11.4 whenever my Mac goes to sleep and I wake it up again, I get a notification to say the "Disk was not ejected properly".  This has never happened with this drive before, not on Mountain Lion, Mavericks, Yosemite or El Capitan until now.  I have another external caddy also with a full size 3.5" drive in it. This is powered by the mains.  It seems to me that the Mac is now terminating power to the USB 3.0 port prematurely (before the disk has had a chance to unmount properly ?), I do not get the message for my full-size disk that is permanently powered.  Tried adding the disk to the spotlight ignore list but to no avail.  Anyone else notices this issue?
