How do I make my external hard drive show up in devices even when the external discs box is checked in preferences?

External hard drive not showing up in devices, even after troubleshooting and checked in preferences.

OK I solved my own problem. My iPhone was plugged into the other USB port in addition to the external hard drive. I took out the iPhone USB and switched the external hard drive USB to the other USB port. The drive showed up in my devices!

How do I make a bootable hard drive clone of my main disk in my mac pro?

Hi everyone,
How do I make a bootable hard drive clone of my main disk in my mac pro?
My main drive has bad sectors and I want to replace it.
Thanks in advance

Also your Mac's Disk Utility can make a bootable clone;
http://macs.about.com/od/backupsarchives/ss/diskbackup.htm
Consider though, if your internal HD is failing and defective, then any clone however made, may carry that defect.
Perhaps it would be better to copy your personal data, photos emails etc, to an external drive as well, just in case the clone did not work because of the failing hard drive.

If you type in finder search "Migration Assistant" you should be able to restore from TimeMachine backup.

I am a school administrator. I want to know if anyone knows how to use an ipad wireless hard drive as a storage device for individual student work files that are only accessible to the student or teacher?

I need to use an ipad wireless hard drive as a storage device. I want the student to do work on the iPad , then save it securely on the hard drive, then be able to go back and get the file and continue working on it. Can this be done?

We use google apps for education with the google drive ipad app
The google drive editor is basic. But it meets our needs. Students go to the app called "google drive". They logon and start a document on an iPad and then edit again using almost any device anywhere(home or school): ipad, windows7, mac, android.
We setup each student account with folders for each teacher. Students can move documents into their teacher folder, and then the teacher can edit in real time with the studnet. It's like a multi player editor.
There's no quick fix to allow students using ipads to save work, then revise alone or with the help of a teacher.
You could also use skydrive, dropbox, or filebrowser, but the ability of ipad apps to edit and save revisions is spotty. It depends if that app developer has added support. You can see your MS Word doc files with those tools, but I don't know if you can edit the DOCX file, then save back to DOCX files.

How do I make an internal hard drive not mount at startup?

I have an internal hard drive hooked to an ACARD ATA RAID controller that I use for backup purposes, and I would like to mount and unmount it manually. Disk Utility in OS9 and earlier had an option not to mount a disk at startup, but I see no such option in OS X.
I can manually unmount the drive in Disk Utility, but it always comes back up when I reboot. How can I keep the drive from mounting upon reboot?

I discovered this in a quick internet search.

Please note that I have never personally done this and am not recommending it. But maybe it will give you some guidance.

Why won't my external hard drive mount in Disk Utility even when it shows up on the list?

Hey all,
For the last few years I've used a Samsung S2 1TB external harddrive to back up all my files, this includes photos, music and a vast amount of resources required for Uni. However I plugged it in for the first time in about two months and discovered that neither my Macbook Pro (late 2011) or my Mac Mini (early 2013) are able to mount the hard drive.
It shows up in Disk Utilty however the harddrive is greyed out and when I manually try to mount it I get an error message saying that it can't be mounted and to use the first aid 'Repair disk permissions' feature which would be all good and well were that not also greyed out.
I've read a fair amount on this forum that suggest that Mavericks has caused quite an issue with harddrives and although I don't know for sure, the harddrive did stop working at a very similar time to when I updated. I've sinced used the basic version of 'Disk Drill' on the harddrive and all the files show up perfectly which leads me to believe that perhaps the issue isn't with the harddrive itself but perhaps a compatibility issue.
I was just wondering whether anyone had any advice or had suffered a similiar issue, preferably in relation to the Samsung S2 harddrive. The partition type is a Windows_FAT_32 and it's a USB hard drive.
Thanks in advance!

Because there's a problem with the disk's directory structure; these are often the result of improperly unplugging drives or forcing a computer to shut down. Proceed as instructed, or try using a more powerful utility such as DiskWarrior to repair it.

How do I mount a second hard drive in Beige G3 its listed in the profiler

Inherited a 300 Mhz Beige G3 with 6 GB system drive running OS 9.2.2
Has a card in SCSI Bus 1 with IDE drive cable. I have installed a 60 GB drive on the sled and the system profiler recognizes it as Mac OS Extended, but says the drive is not mounted.
Hate to be stupid in front of so many people but, how do I mount the drive.. the profiler is the only place it shows up?
Also has a Firewire/USB card in PCI slot 1. Any chance firewire or USB will actually work?
I eagerly await your responses.

Some PCI-slot Drive Controller cards report to the System they are SCSI Controllers to be able to use the more mature and flexible SCSI drivers with "Logical Block Addressing" instead of the older "Track-Head-Sector" addressing. Track-Head-Sector has not worked for so long the drives are all faking that they have 32 or 64 heads, even in drives only 9 mm tall.
These Controllers can then support up to two drives, often larger than 120 GB each, on each of two cables, if they have places to plug them in.
One problem is that if you format it in OS 9 on the motherboard-attached cable, you only get the ATA/IDE driver. If you want to move the drive to the card later, you really do need the SCSI driver on it, so it must be reformatted while attached to the PCI card.
If you have an OS 9 CD, a later version of OS 9 Drive Setup can be found in the Utilities folder on the CD. You need not boot to the CD or install to use it, just insert the CD, and when it mounts on the desktop, open the Utilities folder and double-click Drive Setup.
Mac OS X will usually format all major brands and many obscure ones. If you check the checkbox for "Install Mac OS 9 Drivers" you get the OS 9 IDE/ATA driver, the SCSI driver, and the IDE/ATA in FireWire Driver ALL installed.

I used a Disk Warrior to rebuild my G4. When loading the program it wouldn't SU with the repair disc so I selected the Disc Warrior as my SU disk and repaired my hard drive but now I can't get the G4 to SU with anything but the repair disc. What do I do?

I used a Disc Warrior repair disc to rebuild by G4 Power Mac hard drive. It wouldn't
startup using the disc and the C key so I selected the Warrior as my startup disc, started up, repaired the disc and now I can't get the computer to startup on it's hard drive. It will only startup on the repair disc. What do I do to get back to normal?

Press the Option key at startup and select the hard disk.

How can I edit lightroom 5 smart previews on mac book pro (mbp) when the lightroom 5 master image files are on my external hard drive is disconnected from the mbp

How can I edit lightroom 5 smart previews on mac book pro (mbp) when the lightroom 5 master image files are on my external hard drive is disconnected from the mbp? So far when I try to disconnect the external HD from the mbp, I get the following pop up window: The disk "external hard drive A" couldn't be ejected because "Lightroom" is using it. Quit that application and try to eject this disk again. When I do that and restart Lightroom 5, the Adobe Photoshop Lightroom - Select Catalog screen pops up but doesn't list my external hard drive A as a choice.
I've reviewed Adobe's Lightroom Help | Smart Previews Lightroom 5 web page and still haven't been able to figure what I'm doing wrong. Any help would be appreciated.

Your internal HDD. by default, is named 'Macintosh HD'. From what information you supplied, it looks like there is already a Lightroom catalog installed on you local (internal) HDD using the standard naming convention Adobe uses as well as a Lightroom catalog on your external drive which you created. To be sure of which catalog Lightroom is loading when it starts up, To do this, start Lightroom as you normally would. After it starts, select the Lightroom menu item, then select the Catalog Preferences item and finally, navigate to the General tab. The Location information will tell you exactly what catalog Lightroom is opening by default. This will likely be the Photography Mac Book Pro Versions catalog on your external HDD. Once that is confirmed, you are ready to proceed. As an additional test/verification, you can shut down Lightroom and, this time, start Lightroom while holding down the ALT/OPTION key. This will cause Lightroom to pause and display a screen which will allow you to chose a different catalog to open. Navigate to the /Users/[user name]/Pictures/Lightroom folder and select the Lightroom 5 Catalog.lrcat file. When Lightroom comes up, there should be no previews or folders as this catalog should be empty. Now you can be certain which catalog is being used and which catalog has all your data and you are ready to migrate your current catalog. Shut down Lightroom.
To migrate your current catalog, use Finder to locate your Photography Mac Book Pro Versions folder on your external drive. Select the folder and select COPY from the context menu. Next, use Finder to navigate to the /Users/[user name]/Pictures/Lightroom folder on you internal HDD. You can start at the Macintosh HD level and work your way down by opening each level (Macintosh HD/Users/[user name]/Pictures). Select the /Pictures folder and then select PASTE... from the context menu. When the COPY/PASTE is complete, you should see the following files on the Macintosh HD:
Macintosh HD/Users/[user name]/Pictures/Lightroom/ and
Macintosh HD/Users/[user name]/Pictures/Photography Mac Book Pro Versions
The Macintosh HD/Users/[user name]/Pictures/Lightroom folder will contain the empty default catalog the Adobe created when Lightroom was installed and Macintosh HD/Users/[user name]/Pictures/Photography Mac Book Pro Versions will contain a copy of the catalog you created on your external HDD.
You are almost done now. Make sure your external drive is still attached for this step. Restart Lightroom using the ALT/OPTION key again. When the Select Catalog screen appears, select the Choose a Different Catalog button (lower left side). When you do, a Finder window will open to allow you to navigate to a catalog of your choosing. Navigate to Macintosh HD/Users/[user name]/Pictures/Photography Mac Book Pro Versions and select the file Photography Mac Book Pro Version.lrcat. This is the copy you just created. Select the Open button and Lightroom should start. You should see all of your previews and settings just as before. Also, in the left hand panel, all of your folder should show up and none of them should be dimmed and none of your previews should display a small exclamation point badge. Either a dimmed folder name or an exclamation point badge indicates that Lightroom can't find the associated image file. If everything looks good, go to the Lightroom menu, select Preferences and then select the General tab. Under Default Catalog, select an option to either load the LAST catalog opened or select the Users/[user name]/Pictures/Photography Mac Book Pro Versions catalog from the drop down. Shut down Lightroom and then restart it normally. This time, when Lightroom starts, you should be viewing the new copy of your catalog. You can confirm this by looking at the General tab on the Catalog Preferences screen (Lightroom/Catalog Preferences menu items). Shut down Lightroom once again and this time, eject your external drive before restarting. This time, your folders in the left hand panel will be dimmed but you should be able to work with your smart previews. If Lightroom should display a Select Catalog screen with the external drive detached, double check your settings as it indicates Lightroom is still looking at the copy of the catalog on the external drive rather than the new copy you made.
Finally, if you are seeing dimmed folders and/or exclamation point badges with the external drive attached, this indicates a problem. You can select any folder and select Update Folder Location from the context menu. This will allow you to navigate to the copy on the external drive and select it. Lightroom will then update the catalog (select to synchronize the content). This will not only clear the dimmed folder problem but also remove the exclamation point badges for all photos in that missing folder. However, it may indicate that not all went well with the copy of the catalog so make sure to verify all went well. You can use the Get Info option on the two folders. You should see the same number of files/folders for both the copy on the internal drive as well as on the external drive but you can't rely on the byte count because of the possibility of differences between the geometry of the two drives. Hope this all helps!

I have an alias of one of my external hard drives in my trash. When I click on "show original" all my external H D 's and my Mac hard drive show up. How do I delete this icon from the trash without loosing all my files?

I have an alias of one of my external hard drives in my trash. When I tried to delete it, it showed that I was deleting 80,000 files and counting. I stopped the delete process and when I clicked on "show original" all my external H.D.'s and my Mac hard drive show up. How do I delete this alias from the trash without loosing all my files? When I tried to drag it back to the desk top, it just made a duplicate and remained in the trash. When I turned off the external H.D., the trash was then empty. Tried rebooting the computer and then turning the external hard drive back on and the alias shows up in the trash again. Much help appreciated.
Rich

In Finder's Menu, select Go menu>Go to Folder, and go to "/volumes". (no quotes)
Volumes is where an alias to your hard drive ("/" at boot) is placed at startup, and where all the "mount points" for auxiliary drives are created for you to access them. This folder is normally hidden from view.
Drives with an extra 1 on the end have a side-effect of mounting a drive with the same name as the system already think exists. Try trashing the duplicates with a 1 or 2 if there are no real files in them, and reboot.
If it does contain data...

To delete files from your external HDD, attach it to your MBP and drag the unwanted files to trash and then empty trash.
Then you select the files that you want to transfer by 'drag and drop' to the external HDD and trash the files on your MBP.
