Why are there multiple drives in Disk Utility?

When using Disk Utility, why is each disk listed twice and what is the difference between the two? If I'm erasing a CD which one is better to use?

The top entry is the drive. Any partitions (volumes) are listed, indented, below it. To erase a CD-RW, select the drive.

Newbie: why are there multiple process started?

Hi I have a simple question to ask...
Q1. Why are there multiple process for webserver instance and http-admserv for a default installed web server? Please refer below:
$ ps -ef | grep web
root 931 930 0 Jan 21 ? 0:00 webservd -r /opt/SUNWwbsvr -d /opt/SUNWwbsvr/https-admserv/config -n https-adms
root 930 1 0 Jan 21 ? 0:00 ./webservd-wdog -r /opt/SUNWwbsvr -d /opt/SUNWwbsvr/https-admserv/config -n htt
root 948 1 0 Jan 21 ? 0:00 ./webservd-wdog -r /opt/SUNWwbsvr -d /opt/SUNWwbsvr/https-mta01.mydomain.com
root 932 931 0 Jan 21 ? 0:03 webservd -r /opt/SUNWwbsvr -d /opt/SUNWwbsvr/https-admserv/config -n https-adms
root 949 948 0 Jan 21 ? 0:00 webservd -r /opt/SUNWwbsvr -d /opt/SUNWwbsvr/https-mta01.mydomain.com/config
root 950 949 0 Jan 21 ? 42:09 webservd -r /opt/SUNWwbsvr -d /opt/SUNWwbsvr/https-mta01.mydomain.com/config
jes 6203 5994 0 10:52:36 pts/2 0:00 grep web
I understand we need 1 watch dog for web server and 1 for admin server but why 2 process for "https-mta01.mydomain.com" and "https-admserv"?
Q2. This is in relation to Q1. If I need to turn on CA Agent for monitoring, which process should I monitor for web server instance and also for http-admserv?
Newbie.

Ans1) That is by design and default behavior. There is one watch-dog process and 2 webservd processes that get started by default. The first webservd is called primordial and the second child webservd is the one that actually serves all the HTTP requests.
Example:
# ptree 6898
6898 ./webservd-wdog -r /space/iws61sp2 ...
6899 webservd -r /space/iws61sp2 -d ..
6900 webservd -r /space/iws61sp2 -d ...
In this example, the pid 6898 is called the watchdog process,
6899 webservd process is called the primordial process
and the pid 6900 is called the child webservd process that actually serves all the HTTP requests.
Ans2) You would monitor the child webservd process.
Thanks

Why are there multiple keychain records for same email account?

I have noticed that it takes sometimes up to 45 seconds for Apple Mail to send (whoosh...) an email. Then I started getting an alert asking for my password intermittently.
I checked my KeyChain Access and note 5 records for this email account dating back to 2007 and while the password hasn't changed in all these years, I note the "Where" field is different in some of these records. So my uneducated hunch is Apple Mail is getting a little confused and having to go thru all 5 records insteads of just one.
As note multiple records for other email accounts and website logins I have.
1. Why is this happening?
2. Is it normal
3. Can I, should I, delete all but one for each item be it an email account or web login, etc.
or
Should I delete all 5 and let a brand new one be created for Keychain next time I send or get email for this particular email account?
I also see there is some info on keychain syncing. Does this have anything to do with my situation?
Thx,
Steven

I'm a little distracted with Steve's passing. He will be missed to say the least
But if it isn't too disrepectful to reply at this time, I'm unclear with your advise because there are 5 items all for the same email account. A couple are duplications, and the others have slightly different "Where" info.
I can't imagine I need all 5 and wonder if I should delete 4 and keep the newest one?
All my email accounts have multiple entries.
Anyone know why this is happening and if it's OK to delete the oldest ones and keep just the newest?

Random question: Why are there multiple virtual consoles?

I'm very interested in every single detail of some things and that has spawned a random question.
Why do we have multiple virtual consoles(proper term?) ? i.e. if I am looking at my desktop I can simply hit ctrl-alt-f3 for example, and poof! I'm at a new login prompt.
What is/are the purpose(s) for this feature? Can someone name off some scenarios?
Thanks!

Why Are There Multiple Instances Of Firefox Preparing To Access Internet According To Firewall Log When I'm Not Launching Them And Nothing Appeared On My Screen

I had closed Firefox after briefly running it and then tried to reopen it anew but got a message that said "Firefox is already running but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system."
I logged off my computer, and later restarted. However, when I checked my Firewall log it showed that during the minute I had my computer on earlier there were about a dozen instances of "Firefox is preparing to access the internet" which were recorded just seconds apart.
I don't have the problem now -- restarting apparently took care of the issue -- but I don't understand why there were so many instances of Firefox preparing to access the internet when I was not clicking on it all those times, the one time I did I got a message that it already was running, and there were no tabs on my screen to reflect all those supposed instances.
Thanks for any insight that folks can offer.

Were that Firefox processes or plugin-container processes?

Why Are There Multiples of My Podcasts?

I have subscribed to these podcasts, and lately, they've appeared to branch out into completely new sections. The artwork is gone and the artists go under "unknown artists", but the source appears to be the same, and whenever I download the latest episodes from that subscription, they go into that section.
Is this happening to anyone else? If so, what is the best course of action here?

You have't told us how whether you download these Podcasts directly on the iPod Touch or through iTunes.
Af you download them in iTunes and then Sync them with your iPod, look in iTunes Podcasts Library and make sure they really are downloaded. If there is a cloud icon with a downward pointing arrow in it to the right of the episode title, then it's not downloaded. Look at this screenshot:
At first glance, every episode shown above is downloaded onto my computer. However, that cloud icon tells me that those (cloud) episodes are not on my computer at all! To download an episode with a cloud, click on the cloud itself.
I don't have the Podcasts app on my ipod, so I'm not precisely sure how it works, but if you do have the app, I suggest you check it; is there a similar cloud icon next to the episode title, that indicates that the episode is not actually downloaded to your iPod?
If this is not your problem, tell us how you download these Podcasts (on iPod or through iTunes), and whether you play your Podcasts in the Music app or in the dedicated Podcasts app.

When I check my boot SSD drive using Disk Utility under Mavericks, I often get "Incorrect number of extended attributes" errors. But if I boot off an external drive and check the same SSD, no errors are reported. Is this a bug in Mavericks?

When I check my boot SSD drive using Disk Utility under Mavericks, I often get "Incorrect number of extended attributes" errors. But if I boot off an external drive and check the same SSD, no errors are reported.
This happens not just with the SSD in my Mac Mini, but with another SSD in my MacBook (both now running Mavericks). So far as I know, all of the kit I am using is in good order (despite the file corruption reports). So I am beginning to wonder if it could be due to a bug in Mavericks? Both SSD drives have been formatted to MacOS Extended (journaled) format. Should I have used a different format, I wonder?
Has anyone else encountered this issue?
Does anyone have a solution?
Or an explanation that might help my investigation of the issue?
Thanks guys,

I understand that the Corsair Force 3 is not one of the SSD drives that are supported on Apple Macs.
I did try downloading and using Trim Enabler, but the error message came up both when it was off and when it was on.
I understand that not everyone thinks Trim Enabler is a good program, though there is a new version out now, so I may give it another try.

I have a Macbook Pro that was slowing down. The HD was nearly full as I do a video work. I removed over 400gb of photos and video and it made no difference. I ran disk inventory x and that says that there is only 60gb on the hard drive but disk utility says there is still 430gb on the HD. How do I remove what DU says is still there.
Thanks

You may notice a difference in available space statistics between Disk Utility, Finder, and Get Info inspectors. This is expected and can be safely ignored. The Finder displays the available space on the disk without accounting for the local snapshots, because local snapshots will surrender their disk space if needed.

Single external hard drive appearing as two drives in Disk Utility

I have a single 3TB hard drive in an enclosure that is appearing as two phyiscal hard drives in Disk Utility (1 "drive" is 2.2 TB, the other "drive is 800MB, give or take). I attached a screen shot so you all can see what I see. This is definitely a single drive (as opposed to some of those MyBook options that actually have two physical drives in one enclosure).
I'm aware that I can concatenate the drives together to make one logical volume, but I'm trying to figure out why on earth this happened.
To give you a picture of the drive's history, it was previously mounted in a Synology 4 bay NAS as part of a RAID 5 configuration. A few weeks ago, the Synology told me that this disk was having issues, so I replaced it, ran a few rounds of disk repair, and it has been working fine since. I'm not going to put it back in my NAS, since the replacement drive is working fine, and I'd like to use this disk for completely non-essential data (as you can see from the screen shot, I have a few smaller drives in use for 'scratch' work, and I'd like to free those up to use as photo/essential data backups).
As stated before, I'm really just trying to figure out how this could happen, and if there's a way to have the single drive be actually recognized as a single drive, without having to concat or anything.
Thanks in advance.

Thank you.
As I originally stated, I took this disk out when it gave me a generic "drive-has-problems" warning, and then put it into a separate (lets call it a quarantine) enclosure, and ran extensive testing and 'repairing,' without actually finding any problems.
I guess what I'm trying to say is that I'm considering the initial error message to be a 'false-positive' of sorts, due to repeated diagnostics not being able to find any acutal errors, logically or physically.
That being said, I have no reason to 'replace' this drive, as it's original function has already been replaced by a new drive. As I originally stated (twice, actually), I'm really just trying to figure out how this might have happened, and if there are any steps (aside from just concat-ing the two 'disks') to to have the disk function as one physical, rather than two physical, disks.

I have an external hard drive from my time capsule that stopped working on me. I am attempting to access the data with a hard drive reader on my MAC. I am able to see the drive in disk utility and under system info USB. But I am unable to access the data.

I have an external hard drive from my time capsule that stopped working on me. I am attempting to access the data with a hard drive reader on my MAC. I am able to see the drive in disk utility and under system info USB. But I am unable to access the data and it does not show on the desktop when connected.

Ok if disk utility was able to verify the drive I doubt there is any problem.. are you trying to open a TM backup??
You need to mount the sparsebundle then check the actual info inside the bundle.
Don't use disk warrior.. if the disk has verified then unless you deliberately deleted files there is nothing that is going to do.
Pondini has a lot of stuff about getting access to the sparsebundle.

But if you have copied info to the TC that is now gone.. and the disk is ok.. I am not sure.. the TC will not have deleted the files itself.

Change the partition of an external drive using Disk Utility?

I wish to change partition scheme, sizes, in an external drive. All the partitions are MacOS extended (Journaled) and they map, according to the layout in Disk Utility, as follows: Partion 1, 2, 3,4 where 1 is at the top and 4, the bottom. I want to make partition 2 larger, so I decreased partition 1 by half. Now the layout is 1 a, 1b, 2,3,4., where 1b is now free space. Disk Utility will not allow me to increase the size of partition 2 by dragging the corner. Which of the following options (if any) will allow me to increase the size of partition 2, without erasing the data, using Disk Utility:
Select partition 2 and manually writing a new value in the size box, equal to the present partition’s size plus the free space?
If I delete partition 1 completely, will I then be able to increase the size of partition 2?
If I delete partitions 1, 3, and 4, will I then be allowed to increase the size of partion 2?
Is there another option?
Thanks
(Actually, partition 3 is an eDrive, a data recovery utility created by TechTool Pro 7, so I don’t really know how it’s formatted.)

You cannot re-size the existing partitions in such a way that you can take the space from a shrunken partition and add it to another partition. Disk Utility cannot do that. If you have an existing partition that lives above another partition, then you can delete the lower partition in order to expand the upper partition into the freed up space. This concept applies to any additional partitions that are below another partition. Disk Utility can do this. You can resize down, but not up, except when creating new partitions. You would need third-party software such as iPartition 3.4.3 to accomplish that feat.

Copying a drive with Disk Utility

I have a USB drive used for Time Machine that is failing. Disk Utility says it can't fix it, but says I can copy files from it.
I attached a new drive and am using Disk Utility's "Restore" function to clone the new drive from the failing one (both are 1TB drives).
Disk Utility says on the screen that it is "copying blocks". Does this mean it's doing an image copy rather than a file-by-file copy? It seems to me an image copy in this case might be bad, because it could cause any file or directory corruption on the old drive to be copied to the new drive.
Are my worries justified? Would I be better off just using the Finder to copy files? Are there third-party programs that might be better? (DiskWarrior says it can't fix the old drive because of insufficient memory.)

I have SuperDuper! but didn't have it installed on that machine and thought I would give the Disk Utility process a try.
I'm fairly sure SuperDuper! must use file copying, not image copying, and I suspect Disk Utility does too. But that "copying blocks" message made me wonder.
BTW, Disk Utility is telling me it's going to take over 24 hours to copy the terabyte. Both drives are connected via USB 2.0.

Help! Phantom Drive in disk Utility, causes problems

Last week I had an external firewire drive fail. I was away and just discovered it today. When I look in Disk Utility, I see a device still listed for the drive even though it won't mount. I unplugged the external drive and restarted the computer and it is still there.
This causes two problems:
1. it takes forever to reboot the computer, as it spends 10-15 minutes trying to establish communications with a hardware device that isn't there.
2. I cannot log out or shut down. I have to cut the power to the computer to restart it.
How can I remove the dead device from the list of devices OSX is looking for? I imagine my startup and shutdown problems are related to some device entry somewhere. Before I start looking into replacing the drive and recovering the data from the dead unit, I'd like to resolve the issue with the OS.
Any idea how to get rid of the traces of the old drive that are still there?

While in Disk Utility and the HD disconnected, CMD or OPT click and drag that icon out of DU's window. It should go poof, just like removing stuff from the Dock.

Unable to verify or repair my external hard drive with disk utility, reason being ...

Hello there,
I have been facing this problem: After I started getting an error 50 error while trying to view in Quicktime player a movie which I had exported from FCPX today, I found that I was not even able to trash the movie [this was a test movie used for export and I had no need for the same]. A little while later when I opened FCPX, I found this message pop up:
Got a little worried and then tried to verify and repair my hard drives using disk utility, but I could neither verify nor repair the disk. What should I do now?

Hello Klaus,
I think I have been able to overcome the problem/s.
I have been using my Seagate 2 TB drive [2 USB] with a FW adapter and was using FW connectivity for the past several months without any problems. About 2 months ago I added a 2 TB Lacie, FW, to my workflow and this EHD was daisychained to the Seagate. Had been facing no problem with this arrangement until today.
Now let me try to tell you what I had done:
I ejected the Seagate drive with the intention of reconnecting it again. But, no, when I tried to reconnect, this message came up:
After several attempts, I did this, connected the Lacie by FW to the FW port on the Mac and connected the Seagate by 2 USB. Was I glad to see my Seagate HD icons shining in all their glory on my desktop! I utilised the services of disk utility and was informed that these prodigal sons were absolutely fine.
I also tried to do this: empty the trash. Was I happy to hear the sound of files being cast out?
Well, well, at least I will be able to get some peaceful sleep now! I have not yet opened FCPX, but I trust it will also be reading the Seagate HD once again.
Good night and thanks for being helpful.

IMac Finder cannot see external hard drive but Disk Utility can

I have a WD external hard drive and it has been attached to my iMac for a year or two. About two months ago I upgraded to Lion 10.7.5 and hard drive still worked. Then suddenly about a week ago the iMac no longer sees the external hard drive in Finder.
I have connected the hard drive to the iMac with different USB cables and into different ports and it makes no difference so deduce there is no issues with the cables or the ports. I have connected the hard drive to an old Macbook and it can see the harddrive and read some of the info but I really need the hard drive attached to the iMac as I store all my music and photos on the external hard drive.
I read another thread and someone asked if you can see the hard drive in Disk Utility. I tried this and Disk Utility can see the hard drive.
What does this mean? Any suggestions as to how to get the iMac to see the hard drive so I can access the data on it?
I dont really know how Disk Utility works therefore if that is any help to me.
thanks

Open the Finder.
From the Finder menu bar click Finder > Preferences then select the General tab.
Make sure: External disks is selected.
