How to eject/unmount stuck volumes?

Hello, a few month ago a minor issue appeared on my MacBook Pro 2012 with Retina display.
The problem is that, when a .dmg image is mounted can't be ejected/unmounted until rebook.
I've tried everything, force ejecting them, ejecting them from disk utility,
killing finder and do that again, deleting the "com.apple.finder.plist", log out and then log in again but nothing.
Only with a reboot the images are disappearing. Exactly the same thing is happening to USBs and CDs at the external CD driver!
When I force eject them, it says that the were ejected, but they are still on the side list in the finder.
I have searched the web the last months but with no results. It's not a very serious issue, but it has become very annoying.

So, we can rule this out as not working:

The file system may be corrupted. To fix it, you need to run CHKDSK on C: Drive.
If you cant boot into Safe Mode to run CHKDSK, or if the Recovery Console wont load, you may need to connect the HDD to another PC using a USB Adapter, so you can run CHKDSK on it.
Also test the Hard Disk for errors by using DFT.
DFT Download: http://www.hitachigst.com/hdd/support/download.htm#DFT
Download the ISO File and burn it to a CD-R Disc (There is also a Floppy Disk version if that's easier).
If you dont know how to burn an ISO file, read this guide: http://www.petri.co.il/how_to_write_iso_files_to_cd.htm
Restart your laptop and boot from the DFT Disc.
Choose the "Advanced" Test and let it run (it may take an hour or so).
If you see a red message box, the HDD is faulty.
An error od 0x70 means there are bad sectors and the HDD needs replacing.

HP DV7-7338ea Windows 8 Unmountable Boot Volume BSOD

The product concerned here is a HP DV7-7338ea with operating system Windows 8. I have been using it for just under 11 months and bought it with Windows 8 installed.
Problem descrpition:
I recently installed a new sound update for my laptop. I was promted to restart and once that happened, I recieved a BSOD with the error message: unmountable boot volume. When that happens, it restarts and goes into "preparing automatic repair" mood after which the screen goes black and the windows cursor shows and then that's it. I am left with no options or anything. I have tried pressing F11 on start up and then it says "please wait" and goes back to the same black screen. I have left it on for over an hour but it just remains there until my computr switches itself off for overheating (this has never happened before). I haven't recently installed any thing new apart from the HP update. Please help as I do not know what to do now. I have not backed up my files yet and they are too important for me to loose. Thanks
Update:
I ran a system check and it said the Hard Drive Short DST failed. Does this mean I have lost my files? The laptop had been operating very well until this latest HP update which may have corrupted my hard drive.
This question was solved.
View Solution.

A harddisk short DST fail means that either your harddrive is failing or have failed alltogether.
If you're still under warranty, contact your retailer or local HP store and get a replacement harddrive that you can switch yourself or have it sent in for service.
If you have an IT knowledgeable friend you might be able to salvage some of the data on the computer.
You can try removing the harddrive frmo your computer and connecting it to his.
Please let me know how it works.

HP Pavillion DV9700 - Vista 64bit - "Unmountable Boot Volume"

Hi there,
The problem I have with my DV9700 is it will no longer boot. It was working great, but the other night, I had to do a hard re-boot, and then it failed to start with a blue screen with "Unmountable Boot Volume". This is with the original Vista 64 bit Home Premium version. I chose the option "Self Recovery" but it just finishes up sitting there continually scanning for something?
The hard drive is the original factory installed setup. My question is, how do I get my machine back up and running please? I have a Windows Vista Backup that would run each week to an external 2TB USB drive, but I am guessing that this will not recreate an exact image of my computers state? I would also need to have Vista running to use the backup? Some years ago (2010), I created a complete backup to about 20 DVD's, but I am not sure how to use them as they are for recovery I think?
It looks like I need to buy a new hard drive but how do I go about using the backups I have to install to a new drive? Also, what is the largest hard drive I can use? Should I buy a SSD drive? I wanted at least a 1TB primary drive. Fry's Electronics has a Hybrid drive where the disk cache is solid state making it more affordable. I was thiking of getting one of these?
I would like to use my old original drive as a secondary drive if it is even possible to access its files. I have ordered a SATA caddy so I can mount it into the unused drive bay of the DV9700.
Anyway, I would truly appreciate any help please?
Thanks a million!!!

Hi mtrappett,
Thank you for your inquiry, I will do my best to assist you.
I grasp that after restarting the notebook you got the error" unmountable Boot Volume" and a blue screen. Here is a link to a document on Troubleshooting Error Messages on a Blue Screen that may Occur During Startup or Boot. For your convenience I am also providing the HP Pavilion dv9500, dv9600, and dv9700 Entertainment PCs Maintenance and Service Guide. Please note page 23, item 23 for a list of recommended hard drives. I hope you find these useful.

R61 R&R won't start after "unmountable boot volume" error

Hello all,
New user, first post - after problem, of course.
I have an R61 Thinkpad with Windows XP on it. (SP2 or SP3, not sure). Has worked flawlessly for years, then the other day I got the dreaded "unmountable boot volume" error and it would not start.
No problem - I re-start, hit the ThinkVantage button, then hit F11 to use the R&R hidden on a separate partition of the hard drive........I get the black screen with the big progress bar, ok, then a blue screen......then nothing. Hangs up and sits there. I have repeated this about 5 times now.
No problem! - I was smart enough to make an R&R CD set a while ago! Put the primary R&R disk in the CD drive, start the machine, ThinkPad button, F12 this time to choose boot from CD.....much CD activity ensues and I once again get the black screen with the big progress bar. It takes much longer, and I get teh blue screen - BUT - then it goes one extra step to display the "ThinkVantage Rescue & Recovery 4" screen with the life preserver image.
Excellent, I thing - except it then hangs there. Just sits there. No disk activity. No keys will do anything.
I can find no threads here or on any other forum with this particular issue.
Am I fubar? Or is there something else I can do?
Thanks a bunch.
Solved!
Go to Solution.

Hi jim, welcome to the forums,
Is the hard drive recognised in BIOS, was there an entry in the boot list against HDD0?
Regardless of it being shown in BIOS / boot list or not, the first thing I would do is to reseat the hard drive and see if that helps, maybe over time it's lost contact to the mainboard socket. If you don't know how to do this you can find out at the R61 movies site.
The next thing I would do is run a hard drive diagnosis check from a bootable cd, these can be downloaded from all HDD manufacturer's websites e.g. Hitachi's Drive Fitness Test. It may be that the drive has simply gone bad after all those years of work.
Let us know how you get on

Unmountable Boot Volume on XP and screen goes blank before repair begins

The XP Windows partition was seemingly working fine until I turned on the laptop this afternoon. Took a minute or so longer to boot than usual and I was prompted when it did load to update Acrobat, which I did and it rebooted. Took longer to boot, perhaps two or three minutes and I received an Unmountable Boot Volume error. I rebooted a few more times, same result. I tried system restore to three previous dates over past ten days and was told after attempted reloading that it had failed and I should try another day. Worried about my data, I went to safe mode to back up C: drive.
The general advice from MS is to use the Windows installation CD to repair the boot sector. With the CD in, Windows will boot and show my normal desktop and files, though will on perhaps the third item to load to memory, the screen goes blank and the loading seems to continue, as I hear sounds though not sure if it is the programs or the repair.
There does seem to be an ability for it to boot, just not maintain it through full load. Any suggestions short of reinstalling windows would be welcomed. Thank you.

I was unistalling some usless programs when my laptop died & when I turned it on I had unmountable boot volume 0x000000ED (the blue screen)

Help!!! T61 Blue Screen--unmountable boot volume-- error code 0000: Read verification failed

My computer is T61 (8891CT), but Blue Screen came out and reported--unmountable boot volume. I ran the diagnostic program and got the error code 0000: Read verification failed. I can’t run anything now including the restore and rescue. Has the hard drive died?
If the hard drive has died, I have to change the hard drive, but how to transfer the system (I don’t have any CD) and think vantage software? Thank you very much for you help.

Hi equalefk,
Yes, definitely sounds like it's time to replace the HDD.
Hope it helps.

How to remove a stuck CD/DVD in drive

I recently purchased a new to me MacBook. I had a new hard drive installed, and I told the technician that I'd install the system software. I guess I forgot to tell him to format the drive. I went to install Snow Leopard, and nothing happened! I tried to eject the install CD by holding down the eject key and it wouldn't come out. I guess it needs a system installed to eject a disk. Does anyone have suggestions on how to eject a CD disk? Thank You.

With your install DVD in the optical drive reboot. As soon as you hear the boot chime, hold down the "c" key on your keyboard (or the Option key until the Install Disk shows up). That will force your MacBook to boot from the install DVD in the optical drive.
When it does start up, you'll see a panel asking you to choose your language. Just press the Return key on your keyboard once. It will then present you with an Installation window. Completely ignore this window and click on Utilities in the top menu and scroll down to Disk Utility and click it. You should see your hard drive in the left hand column along with your other drives. Click on the drive and select the Erase tab. Set the format value to Mac OS Extended (Journaled) and click the Erase button. After that has finished select the Partition tab. Type in a Name for your hard drive and select how many partitions you want from the Volume Scheme. The usual setting is one partition. Click on the Options button after you've selected apartition to make sure it's set for GUID. Then click the Apply button and after the Partitioning is done quit Disk Utility. You can now follow the instructions on the install screen
