I can't access my portable external drive anymore.

I can no longer access my external drive. I can see it in the system profiler but not the disk utilities. What should I do?

At the Apple Icon at top left>About this Mac.
Then click on More Info>Hardware>USB, does it show up there?
No idea why Mobile me is popping up.
"Try Disk Utility
1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair. Disk Utility checks and repairs the disk."

Can't Access Photos on External Drive

I attach my external drive (Toshiba 320GIG) and open, which gives me the external drive window. I click on Toshiba on the left-hand-side menu, then begin to enter IMG in the search window. As soon as I type the first letter, the menu highlight defaults to my hard drive menu item and I can't search in my external drive. What am I doing wrong?
Thanks for reading. Any help appreciated.

So, you have two versions of iphoto? One from the old machine and one from the new?
If so, forget about opening with the older version of iPhoto.
For the newer version:
Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

How can i access my lacie external drive with os mountain lion

I have just upgradet my macbook pro from snow leopard to mountain lion, and now i can't restore my backed up files from my Lacie external drive.
When i try to connect to it through time machine or migration assistant i get the message:
"the version of the server you are trying to connect to is not supported"
I have tried to enable all UAMs but i still can't connect.
I have browsed after other similar situations, but i can't seem to find any though i'm hardly the only one with this problem.

If the backup was made using time machine, you should be able to access any files you need or want manually using the finder. It may not be pretty, but it should work. I don't know why the migration assistant would be unable to access it though.
If you can't access the contents of the backup with the finder, then I would say your problem is a bit more serious.

Can't access libraries on external drives

I keep my archived images in a separate library backed up on 2 separate external drives. This system was working fine until recently. Now Aperture crashes when I try to access them. My laptop (the main work-horse) is pretty full and Ap has been running slowly, so I cleared some space. Now have about 20 gig free, but no change, so that doesn't seem to be the problem. Any ideas? Thanks in advance.

Hi General Confused
- I have also posted some enquiries about the subject of Aperture2 no longer accepting Vaults;
there are several other people enquiring too : I cant help but think there is (sadly) some bug in the newest updates???
No serious response as yet, I'm thinking that the only solution is to trash the (seperate) "vault" drive and start a fresh !!!!

Can't access files on external drive clone

I've cloned internal drives several times before with no problems but I'm having trouble this time.
When I attempt to boot from the external clone it reaches a point where it asks for my admin password (never seen that before) and then it refuses to recognize the correct password (the window shakes its head 'no') and I am unable to do anything but restart from the internal drive. I know my password is correct because I had to use it to enable cloning with Carbon Copy Cloner. I even tried a second time after switching to no password for the admin account. Same result.

Funnily enough, I've had the self same problem, see here:
http://discussions.apple.com/thread.jspa?threadID=288377&tstart=0
As you will see from the thread, I couldn't resolve it and ended up wiping the partition and recloning as per the advice given me. If you find another way around it, post back here. It rather defeats the object of having a 'clone' if when you need it it's unusable.
Good luck

OK. Start iTunes, then open the preferences by selecting the menu item:
"iTunes > Preferences...":
Then click the "Advanced" se we can see where iTunes thinks the library is.

Portable external drive recommendations

I'd like to use a portable external drive to store my referenced masters (about 15k jpeg images and growing), which I would back-up periodically to a 1 TB LaCie drive. Other than getting a drive with FW800 (compatible with my MacBook Pro), should drive speed (5400 vs. 7200) be a consideration? I've noticed that 7200 rpm drives generally max out at 500 GB (and are generally more expensive), but I'd like to get a 1 TB drive. Any recommendations or suggestions?
Also, any suggestions for backing-up referenced masters from one external drive to another (frequency, approach, tools/software)?
Thanks

I buy memory and mass storage from OWC at
http://eshop.macsales.com/shop/firewire/.
Plenty of 7200 rpm choices available including 1-TB size, and yes I consider 7200 rpm worthwhile. I recommend drives that allow FW800, eSATA and USB for flexibility. Slow USB-only drives for backup only can save a few bucks, but drives are cheap and I like to be able to repurpose drives instantly if the need arises so I pay extra to maintain multiple connectivity choices.
As to backup, I feel strongly that originals should be backed up before import into Aperture or any other app. Frequency of offsite backup depends on how important the image data is to you. Personally I do not erase CFs until the originals are both on the hard drive they will live on and backed up to an offsite drive (which can be as simple as a drive that lives in the car). The point is that one theft or one fire or one whatever cannot forever lose enterprise-critical photos.

Trouble Exporting QuickTime on to portable external drive

I bought a portable external drive (Lacie) and I am unable to transfer my project on to it in the form of a self contained quicktime video export.
I tried to copy it from the Lacie external drive that I first exported the project to and I got an error message, "type 36" that said it couldn't copy or read part of the file and it aborted the copy. Then I tried twice exporting the project straight to the portable drive, and each time, instead of exporting one self contained QT file, there are three files: the origional file name and the second and third files have: "av1" and "av2", added to the origional file name. So it looks like its exporting the video and audio seperately?
I imported the main file back into Final Cut to see if it would play on a timeline and it did. But it is one third the size (2 gig) of the origional exported self contained video (5.5 gig). So something's not right.
I am trying to give my editor one file so that he can make a DVD.
Does anyone understand what's going on? It seems to me the problem lies with the new portable drive but I'm not sure what to do. Thank you for any help, guidance, or further trouble shooting.

Reformat the drive Mac OS Extended with Disk Utilities found in the Utilities folder in the Apps folder. (Click on the erase tab) if you haven't already done this.

Using an external drive with shared files (iPhoto, iTunes), attached to a Time Capsule, can the contents of the external drive be backed-up to the internal Time Capsule drive? Perhaps a RAID1 mirror to a partition?

Using an external drive with shared files (iPhoto, iTunes), attached to a Time Capsule, can the contents of the external drive be backed-up to the internal Time Capsule drive? Perhaps a RAID1 mirror to a partitioned Time Capsule? I understand that the Time Machine (software) cannot backup a networked drive (the external) and that Time Capsule (the router/wireless hard drive) does not have its own backup software... so it won't backup the connected drive. What I would like is an alternate solution for having an automated backup of a networked drive. A 2TB Time Capsule has more than enough space for Time Machine backups of my family of Macbooks, so I had hoped to mirror a 500GB external drive (with shared media files) to a portion of the Time Capsule internal hard drive. I assume this would require a partition of the Time Capsule drive. If not, would the sparse file from the various computers being backed up need to be copied to the external drive as part of the RAID1 setup? This seems like overkill for the Time Machine backup, but it would cover the media files.

The complexity with this idea is the software has to run from a Mac computer on your network.. so you need a Mac turned on, probably most of the day.
It isn't possible to partition the TC although you can create a image area.
The software would have to copy the material, that means all files to be copied, go from USB drive, back to the Mac, then back to the TC, and written to the drive. In other words you have just added Network congestion, although a proper incremental backup type software will not actually use a lot of capacity.
Finally it will be slow.. network drives are slower than internal drives. Well USB connected drive is much slower than the same drive connected directly to the computer.. and if the drive is connected directly to a computer it can be shared with the network.

Read carefully the speed of the USB drive plugged into the TC.

Can I use a 2tb external drive with Time Machine to backup my Mac Mini (256gbSSD + 2tbHDD)?

Can I use a 2tb external drive with Time Machine to backup what I have on my Mac Mini?
My Mac Mini has one 256 SSD and one 2tb HDD. I want to use Time Machine to do a backup of everything.
Would an external 2tb My Passport Drive by Western Digital work for the backup?
It seems like it would not work because the total storage on the Mac Mini is 2304 gigabytes (SSD + HDD).
And the external Western Digital drive is only 2048 in gigabytes versus 2304 gigabytes the Mac Mini has.

No. A Time Machine backup drive should have at least twice the capacity of the drive it backs up. You would need at least a 4 TB backup drive for Time Machine.
Might I suggest as an alternative that you not use Time Machine but a third-party backup utility that simply overwrites older files with new ones such that the backup drive can be the same capacity as the drive backed up.

Can I boot from an external drive with a "Virtual CD"

I just purchased a Hitachi LifeStudio external hard drive for use as my Time Machine backup. When I plugged it in to my MacBook running 10.6.4, I realized that it had one of those "Virtual CDs" that contained the manufacturers crapware, similar to Western Digital's MyWare or whatever its called. It shows up in disk utility as an actual separate disk and not just another partition that can be wiped.
I reformatted the drive using GUID and and created 3 HFS+ Journaled partitions. One was going to be for the 10.6 installer, one for the 10.6 boot, and one for my time machine backup. I restored a 10.6 install dvd disk image I created using disk utility to the 10.6 installer partition (with erase destination checked) then option booted my mac and the partitions did not show up. The only thing I could see was my internal hard drive.
I have done this many times before and it has always worked so Im trying to figure out what Im doing wrong. The only thing I can think of is that the "Virtual CD" that Hitachi put on this external drive is stopping the Mac from seeing the bootable partitions I created. I even went into system preferences>startup disk and blessed the 10.6 install partition. That didn't work either, the computer just booted to my internal drive.
So my questions are. Is it because of this "Virtual CD" that I can't boot from my external drive? If so, is there a way around it? I already searched their web site and emailed their tech support asking for a firmware update to remove the virtual cd.
Thanks in advance.

Yes, it's a known issue. You've already referred to the issue with WD systems. WD has a long list of products that are either not compatible with Macs or won't boot a Mac.
There are practically no problems with bare drives, but once installed in an enclosure there is no guarantee that the package will function as a bootable device. This is especially the case if the manufacturer uses some sort of "virtual" scheme intended for using the device as a sort of one button backup device.
External drives don't have to specifically say anything about being Mac bootable or compatible. It's up to the consumer to verify compatibility and usability.

Can I use a portable hard drive for ipad data storage?

Can I use a portable hard drive for ipad data storage? I want an iPad mini, but don't want to get a large one (memorywise) along with cellular capability. I remember that the old iPads coiuld not communicate via their iPhone connector to transfer data. So can I do that iwth the newest iPad mini via the lightning connector somehow? Thanks, Tom

No. But you can with Seagate's wireless GoDrive.

MacBook Air, can I partition my Mac external drive to have an ISO image file location for Windows downloads?

Time Machine will not let me restore from recent backups. I can see them on the external drive but will not restore sooner that June of 2013! Any suggestions?

All I can suggest is that you open that file on the MBA and save it as a new file, then see if you can open the new one on the iMac.

I can read but I can't write to an external drive - changing permissions

I can read but I can't write to an external drive.
How do I change permissions? None of the helps here on the discussions have helped.
Why would a computer company let me read files but not write? Hahaha. This is insane.
I have to write computer files for work. It's a project due this morning.
Man, I'm going to have to go back to PC.
Just need the compter to write files.

If it's formatted as NTFS, reformat it as MS-DOS, exFAT, or Mac OS Extended (Journaled) as desired.
If it's formatted as FAT32 or exFAT, use the Disk Utility's Repair Disk command on it.
If it's formatted as Mac OS Extended, click Authenticate and provide your administrator password, or change the permissions on that specific folder in its Get Info window.
