Delete Install ESD and OS X Base system

[soroush1359]

Dear Forum,

I have an issue, like most IT folks I am a bit of OCD, and like my boot section look clean and free from unnecessary mounted /unmounted and virtual disks and volumes.

I have about 16 disks showing up when I do a Diskutil list in terminal. disk 0 is my physical drive, disk 1 is my bootable flash drive with el capitan and the rest is just what I don't want. Even though I pluged in my hard disk to a win 7 pro and did disk part and cleaned all the EFI partitions in my physical hard disk, I still see a lot of other ones in the list. I have also reset the P-ram or the NV-ram as well (or I think I have done it, by unpluging, removignt he ram, command+option+p+r and three beeps etc.)

Anyone knows how to proceed to remove all the extra volukes and disks?
thx
S

Welcome to the Forums.

We have no idea of what you're referring to? Provide us with info: Mac model and year, version of OS X you're running. And, a screen shot of the diskutil list from terminal.

Welcome to the Forums.

I have a i5, 27inch, 4 gb, 500 gb sata, 2009 late iMac and I have a 8 gb El capitan bootable flash drive plugged in one of the USB ports in the back.

When I start up the machine with Option key pressed in, USB drive pops up and I start the installation with El Capitan from USB drive. Then I start Terminal and run Diskutil list command. It gives me a list of all disks and volumes available in the system. disk 0 is my physical Sata HD drive, disk 1 is my bootable flash drive with el capitan and the rest is just what I don't understand and want.

I see Mac Osx Base System and Install ESD and a alot of other disks.

Even though I plugged in my hard disk to a win 7 pro and did diskpart and cleaned all the EFI partitions on my physical hard disk, I still see a lot of other disks/volumes in the list. I have also reset the the NV-ram as well (or I think I have done it, by unplugging, removign the ram, command+option+p+r and three beeps etc.)

It's a bit hard to read but you show: 1 recovery partition, 1 El Capitan partition, and 2 additional partitions. Actually only 3 partitions all together not counting recovery. The others are disk images which you can safely delete if you no longer need them. They are not disks.

Everything OK here around Fort Worth. The heavy rain and flooding were located in East Texas close to the Louisiana border. Last week most of the flooding was around Houston which sits right on the Gulf. Most of South Houston is reclaimed land which the water takes back every time there's heavy rain or a Hurricane.

As I mentioned earlier, I already have estabilished the fact that I dont need them I just like to remove all but 1st and 2nd entries, but how!

You can not delete the first four entries, only what follows. Where are those disk images located, only you know, we don't? Find them and delete them. If you're having difficulty, make a backup (clone backup) of your Macintosh HD partition and Recovery partition, and then erase the drive. Use the clone to restore. Or boot your machine to the Recovery partition, use Disk Utility to erase the drive, reinstall OS X, and then restore your data from a Time Machine backup that you make prior to erasing the drive from Recovery.

I had a similar issue with a something that showed up as Apple UDIF read-only compressed (bzip2) Media and Flash Player listed below it. It was a leftover from a long past flash update. I could not eject it either so I opened up Disk Arbitrator and it allowed me to unmount/eject it. It is a free utility used for forensics. What it does can be found here:

Or open Disk Utility and unmount anything other than the first four on your screen, then look for files ending in .dmg and delete them. Those "drives" are actually install images for things you have installed.

Yeah, we got it all the last couple weeks. I'm about 90 miles east of Houston. We didn't flood as bad as Houston but Woodville and that area got hit bad. Couple tornados around Jasper and lots of heavy rain.
