Permissions problem with External Hard drive.

Hi,
I've been using my external hard drive for almost a year now and out of the blue last night I ran into a interesting problem. For some reason I couldn't transfer any files to a thumb drive and shortly after I realized I didn't have Read and write permissions for any files on my mac, and everything required my password to get to. I went into disk utility and repaired the permissions and the list went on forever. Upon completion of that nothing was resolved.
SO! I popped in my Snow leopard disk and did a repair of the permissions and system through there hoping that would fix it. I than booted up the main drive and got stabbed in the face with a HUGE error message upon the apple loading screen with a "MISSING DRIVER" "KERNAL ERROR" "CORRUPT FILE" etc.
I went back and did a restore from my external harddrive hoping that would work, and it did. I can access my time machine backups from my external harddrive but cannot do so through my own control.
What should I do? Should I reformat my external harddrive? Which would suck because I'm a paranoid freak and if something would happen during the reformatting I will lose literally over a year of work that is crucial.

Can anyone shed some light?

What is that, a "clone?" What do you mean by "cannot do so through my own control."?
What should I do? Should I reformat my external harddrive? Which would suck because I'm a paranoid freak and if something would happen during the reformatting I will lose literally over a year of work that is crucial.
Again, what's on that drive? Do you have a clone and TM backups on the same external? If so, are they in the same partition?

This one says you need to repair or reformat the disk; that means your backups are corrupted.
Try to do a +*Repair Disk+* (not permissions) on it.
If there are errors that Disk Utility can't fix, or the +*Repair Disk+* option is grayed out (meaning OSX has already determined that it can't fix it), post back.

Error code 36 (problems with external hard drive)

I have just upgraded to Yosemite and am now having major problem with my external western digital hard drive. I cannot create new folders and when I hit command N I get error code 36. I also cannot move files from one folder to the next. When I try to move them I get the error message: "The operation cannot be completed because a file of that name already exists" and that simply isn't true. None of the files' names exist in the other folder.

Ok, It appears to be the fault of Western Digital. I ejected the hard drive and then plugged it back in and it said that the drive was broken but I could still read the files and it told me to save the files on another disk and reformat. So it was just a coincidence that I upgraded to Yosemite at the same time that my external hard drive broke.

Backup problems with external hard drive

I bought a WD passport external hard drive and copied my itunes library onto a file there. I re-set the location of the library on itunes to the drive on the external hard drive. So far I have not deleted anything from my computer hard drive. However, when I am in itunes and click onto a song, nothing comes out of my speakers. Everything looks normal, as if the track is playing, but nothing is happening. I tried buying a new track off of itunes online, downloaded it, and installed it on my ipod; it plays fine, on my ipod, but will not play on the computer. Something is obviously wrong, but I can't figure out what has happened. Any help out there?
Thanks!

It sounds to me like your iMac is on it's last legs....at least the internal hard drive. If you can't make a new Time Machine backup I would advise you replace your iMac as soon as possible.
Assuming your three-week old backup is sound you should have no problems moving everything over to a new Mac. I would recommend you use the Setup Assistant that appears when you start up the new Mac (and note: It only appears the first time you start the new Mac; you can move everything over later on via Migration Assistant, but you may see issues with accounts if you opt for that route).
I don't think you need the Genius Desk for Setup Assistant. You only have to power up the new iMac, answer a few questions....select "....From Another Disk..." When it asks how you want to move everything over....connect up your Iomega external drive...and wait for it to finish. (Could take several hours depending on the amount of data you're moving).
A couple of notes:
1. If your Iomega is a Firewire drive you'll need a Firewire to Thunderbolt adapter to connect it to your new iMac.
2. If you need to load CDs or DVDs remember the new iMacs don't contain an optical drive. You would need to get an Apple SuperDrive or third part external burner if you need that functionality.
I'm puzzled by the comment made in Seventy One's post questioning the reliability of the new iMacs. I upgraded from a 24" early 2008 model to a 27" model and everything works flawlessly. I hardly ever see the beachball anymore.

Problems with External Hard drive, will not mount and errors in disk utilit

i have a powerbook g4 aluminum. i have an external hard drive for it. a simple tech 100gig portable drive, almost brand new. i dont know what happened to it, but one day i was starting my computer up with it attached. it wounldnt fully start up, said "waiting for local disks" so i uplugged the external hard drive. now it wont mount and will only show up in the disk utility of my friends macbook. i tried to verify and repair, and this is the message i got.
Verify and Repair disk “UNTITLED”

Im in mexico writing a book and so i really need help on this one guys.

Hi, hjbugs, and welcome to Apple Discussions. Disconnecting the drive while your Powerbook was accessing it probably caused your problem. It may be repairable using DiskWarrior or TechTool Pro, but if you don't have access to one of those and aren't going to buy one, reformatting the drive with Disk Utility may be the only other way to make it usable again. If it contains data you need to recover first (i.e., data that isn't also stored on your internal HD or other storage media), download the free demo version of one of the data recovery utilities mentioned in this thread and use it to see what is recoverable. If the files you need are recoverable, buy the full version of one of the utilities and recover them.

Problem with External Hard Drive

Hi,
I'm having trouble with my External Hard Drive, a 300GB Iomega USB. Everytime i use it with my iMac G4 it disconnects by itself and i get the "Device Removal" message after 20 minutes or so. This occurs even though the Mac hasn't moved, the Hard Drive and its wire wasn't moved and even when I'm not doing anything on my Mac. This occurrs in all three of the USB ports even though other devices plugged into them work fine.
It's a problem with your External Hard Drive and/or its wire i hear you say. However, the External works fine when plugged into my Windows Laptop.
Any help would be much apreciated as all my music, movies and work are on my External.
Thanks in advance,
K

Hi there:
You may have to use a Mac disk utility on the external USB hard disk drive, since the error
you see is likely caused by some defect. And the symptom is in how the drive fails to mount.
Perhaps a tool like Disk Utility could see what kind of errors, but not fix them; if this is the
case, a more specific tool such as DiskWarrior (for the Mac OS your machine has) may help.
Depending on the level this problem exists, the drive may be repairable through use of one
of the disk utility type of tools; or it may need to be erased, reformatted, etc. So, if there is
some kind of error in the directory or other portion, DiskWarrior could probably fix it and not
interfere with the data on the drive... Or, that's the hoped-for outcome.
And that direction is likely one to pursue. For the sake of discussion, you - do - have extra
USB cords, just in case you have one that does not like Macs? A diabolical PC infiltrator?!
Good luck & happy computing!

When is Apple going to fix the problem with external hard drive not working on Lion?

As for everyone else external hard drive does not work with Lion.
When will Apple fix this problem. Do they just ignore the customer : (

Copy off all your data off the NTFS formatted drive to another drive
Open Disk Utility in the Applications>Utilities folder
Select your external NTFS drive on the far left, should have the drive makers name, a ID perhaps plus the word "media"
Click the Partition Tab, click the big box and click 1 Partition
If you want a Mac only drive > Option: GUID >format OS X Extended (Journaled)
If you want a Mac/PC drive (for over 4GB sized files) > Option: MBR > format exFAT
If you want a Mac/PC drive (for the most compatibility with other devices, Win XP, but only under 4GB sized files) > Option: MBR > format MSDOS (FAT or FAT32)
Give it a name and click Apply.
You can also search Microsoft for a free exFAT download if you have Win XP.

Hardware or software problem with external hard drive?

Hi folks. I have an OWC Mercury Elite external hard drive with a capacity of 500GB. I'd been using it to back up my iMac for about 1 1/2 years by copying my "home user" folder into the external drive. I was keeping about three old backups on the external hard drive and there was plenty of capacity left. Then all of a sudden when I tried to back up, I got an error message that said something like, "cannot copy Desktop5 because of insufficient space."
I tried to fix the problem by deleting all but my most recent backup, but it didn't help. Right now, the external drive is showing "Capacity" of 465.64GB with 11.69GB listed as "Available." I have a complete backup of 32.63GB and a partial backup of 15.46GB on the external drive, but otherwise I can't find anything else on it.
Is this problem caused by my external drive, my operating system, or something else (i.e., ignorant operator)? Many thanks in advance for any help you can give.
Regards,
John

Easy thing to miss, especially with an external drive that you are mounting and unmounting. Glad to hear you're back in the water.

Aperture 3 problems with external hard-drives

Because of an external drive failure I had to move my Aperture Library 350+gb to another external hard-drive (iMac only has 500 gb internal drive). It is working; however, about 2500 photos are referenced, the rest are managed masters. No problem apparently with masters. But cannot reconnect with referenced files because the external drive is now deceased and cannot be dismounted. (Please continue reading before firing off an answer telling me to repair the database with Opt Command at start up. That did not solve my problem.)
I know how to individually reconnect files which were located on a (now) offline (permanently) volume. But is there no easier way to get Aperture to recognize that a drive no longer exists and a new drive has taken its place? (Yes. I have read about using SQLite Database Browser to change the UUID of the drive to the new drive. But this seems bizarre that a high end program like Aperture 3 requires users to tweak the database to get Aperture to recognize a new drive.) I have installed the most recent Aperture update. There was one today I believe. No help.
Thanks for your input.

No, it doesn't appear to be Mavericks. All good here on the five Macs in my studios and all attached drives. But blame Apple if it makes you feel better.

MacBook freezing and crashing/running slow, problem with external hard drive

I've been having some issues for the past couple months with my laptop randomly freezing, usually when I have a lot happening. I've ended up having to hard-restart it several times because it will just hang and I can't get into the menu at all to force quit things. In the past couple days, it's now started crashing completely, although restarting okay. This last time, though, it crashed while I was trying to empty the trash and since then it's been crazy slow and not very responsive.I tried running disk utility and ccleaner, and although they repaired some stuff they didn't fix the problem.
I think iTunes might be the issue. I was trying to move my music library when this last thing started. I have it all on an external hard drive, and I was trying to move it from one folder to another. I tried repairing the external hard drive with disk utility to see if that was the issue, but now my files have all vanished and the external appears blank.
I also recently installed BootCamp, if that makes a difference.
I'm mostly just really unsure what to do. I don't want to do anything to the external because I need to recover the stuff that was on it, but I also need my laptop to be usable.

Thanks for the response. I tried booting in recovery mode and running disk utility again and that seemed to help. It's still hanging when I plug in the external hard drive but otherwise seems to be working okay. My main issue now is the invisible files. I tried booting in Windows, planning to install Recuva to try and get the files back. However, they show up fine there. This is a relief but I'm not totally sure what is happening. I'm guessing the disk has somehow mounted incorrectly on the mac portion but I'm not sure how to fix that. I'm about to restart on the other partition and see what's going on there.

Problem with External Hard drive connection with PowerBook

I recently bought a Seagate FreeAgent/Go 500gig portable drive (2009) that only has a USB hookup. It does not register or operate on my PowerBook (G4 2005) but works fine on my wife's MacBook (2008). It appears from other discussion boards that it may be the case that not enough power is going through the USB port to the external hard drive. If this is correct is there a recommended solution so I can use the Seagate on both computers? Is there a way to get more power through the USB port?
I'd hate to have to go out and buy another external hard drive with an external power source because it would defeat the purpose of being portable if I have to have separate outlets for both the powerbook and the external hard drive (not to mention more cords). Any suggestions would be greatly appreciated.

Are you sure an additional USB to power or "Y" cable didn't come in the box, ****123? Most USB powered drives seem to come either with a "Y" cable, or an additional USB to power cable, these days.
In fact the "Seagate Freeagent "Go" Quick Start guide (see http://www.seagate.com/staticfiles/support/freeagent/fago_mac_qsgr3.pdf ) actually shows one as necessary for using over USB (though this is the model with FW as well).
Seagate's own troubleshooting document concerning this issue can be found at http://seagate.custkb.com/seagate/crm/selfservice/search.jsp?DocId=213059&NewLan g=en

Having problems with External Hard Drives on my Laptop

Ever since using linux i've always had the same problem. Whenever i connect a hard-drive, it keeps disconnecting/ spitting input-ouptut errors.
I thought it was because of the hard-drive failing, which turned out to be the problem with my last two, but i'm using another one (Seagate MomentusXT 500GB) and i'm getting the same problem.
I had just reformatted this hard drive from NTFS to Ext4 using Gparted, so maybe that's the problem? I'm really kind of lost.
I mount my HDD like this:
sudo mount /dev/sdd1 /mnt/usb
and unmount like this:
sudo umount /mnt/usb
It connects initially, and i'm able to put stuff onto it. I was able to put a whole TV series on it successfully, but when i tried copying my music onto it it failed and alot of the music didn't copy, giving me these errors:

I can then unmount and mount the HDD again, and try again, but i keep getting the same problem.

Anyone know how to fix this?

There is a whole lot of bad going on there.
There are problems both drive errors and USB errors. I don't believe it.
I have a hunch the drive is starving for power.
USB devices are supposed to function all the way down to 4.25V. Not all do.
USB ports are supposed to be able to deliver 4.25V at the end of the cable at 500mA. Not all do.
USB 2.0 devices are not supposed to draw more than 100mA unless they negotiate for more. Some violate that.
USB 2.0 devices are never supposed to draw more than 500mA. Some violate that. Especially disk drives.
My guess is that your drive is drawing excess current and the voltage drop through the port and cable are dropping you below 4.25; or at least below the voltage that your drive goes "Tango Uniform"[1]. Does your drive have the option for external power? If so try it. Following up on wtx's comment; USB 3.0 is capable of delivering more power. Also, some drives have used a cable that violates just about every aspect of the USB specification: A "Y" cable that plugs into two host ports to provide more power to the guest. I despise this solution with every fiber of my electrical engineering existence; never-the-less, you might try one.

Permission problems with external hard drive

Hello there, I'm writting you from Paris but my french is just not good enough to really explain my problem. I'm no computer expert so i might not use the right name for stuff but i will try to be as clear as possible.
I have a macbook pro 13" from early 2012 and I'm currently running Mountain lion.
At home i use an internet modem that has an internal hard drive of 250gb. and it also gives you the possibility to conect other usb hard drives on it so you can access them through wifi.
I currently have to usb hd of 1tb each, one i use it for Time Machine and so far it works fine and i haven't had a problem with it, all back ups have been done ok. In the other one i have all my films and tv shows and stuff like that and it is in this one that i have the problem. In certen files and folders i'm not able to do anything with them, i tried to rename them but it says i don't have the permission to do it, i tried to delet another one and it said pretty much the same thing, some other time i tried to move the file to a diferent folder it it would ask me for my password and after type it and press enter it would just not move them, no error messager or anything it just didn't do it. Most of the times i have a messager saying stuff about permission or things like i can't read the file. The thing i can't understand is that as soon as i plug the HD on my mac it works fine i can rename and change stuff, I noticed that some of the files and folders have a little lock on the corner, but they aren't the ones i tried to move or rename before and i tried already unlocking all of them but eventhough i manage to unlock them when i plug the HD back to the modem it keeps the same, can't rename or move, not even to the trash.
Can anyone help me out here? I'll be really thankful
Cheers!

Problem with External Hard Drive - Firewire

I have a problem with a *300GB Venus DS3 Hard Disk* / USB 2.0 - Firewire 400 (not sure if 400).
I have a +Mac G4 (1GHz Power PC G4 / 1GB DDR SDRAM)+ running +Mac OS 10.3.9.+
I connect Venus hard disk through USB cable and no problem. But when I want to connect it via Firewire it doesn´t appear in the desktop.
If I go to *System Profile* it says that there is a device connected to the FireWire port but i can´t see it in the desktop and if a open *Disk Utility*, there is no other hard disk besides the internal, so I can´t mount the Venus DS3 Hard Drive.
I looked in the internet and found this page -> http://american-media.com/support/downloadDDDS2316CBK.html
I was about to download the *Firmware Update* but i read this:
AMS is not held responsible for any damage caused by misusage of this utility! Use at your own risk and be aware that your warranty might be void! DO NOT CHANGE
ANY SETTINGS WITHOUT CONSULTING TECHSUPPORT. Do not distribute or post these files on the internet!
I searched in Internet and found that many persons had issues connecting Hard Drives using Firewire port and read some tips (like unplugging all the usb firewire devices unless mouse and keyboard, disconnect AC cable, wait 15 minutes, ...) but couldn´t fix the problem.
I also wrote several emails to the manufacturer of Venus hard drives (American-Media) but so far no answer.
I would really appreciate it if someone could tell me how to connect the Venus DS3 to a Mac G4 (OS 10.3.9) via FireWire.
Thank you very much

I suspect the problem is in the size of the drive. You say the drive was formatted for Mac and Windows. How did you do that? With older Macs, there is a 128 gB limit on drive size.
Here is a link to a third party disk utility that claims it gets around the size limit:
http://www.SpeedTools2.com/
Another possibility is to connect the drive to a Windows machine and re-format it into 3 volumes, each less than 128 gB. The Mac should be able to see the partitions.
Sidebar comments:
• The way I read the information on the AMS web page that you cited, you do not need a driver. And that is consistent with my experience with firewire enclosures.
• Inside the AMS enclosure, the drive is a standard ATA/IDE drive. That you can use the drive with a USB connection is proof the drive itself is working.
• The "bridge" is a key component in FW conectivity. (That is a piece of circuitry that sits between the IDE drive and the FW connection. It is inside the enclosure.) It appears your enclosure has the Oxford 911 chipset on the bridge. That is good.

Huge problem with external hard drive.. need help

Hey everyone! After a series of unfortunate events that began innocently enough, it appears I've trashed my WD 60 GB external USB hard drive.
I was using the drive to back up my iTunes library. When I found that it was also backing up my 30+ GB of video onto the drive and saw how slow it was, I clicked "stop" in iTunes which actually caused it to 'unexpectedly quit'. (I saw it coming).
So I tried to delete everything off the drive so I could try again (after removing videos from my iTunes Library). I found that it wouldn't let me delete everything, so I went to Disk Utility and went to erase to get rid of anything on the drive.
That failed multiple times and I kept quitting out until I got it to work. Now that's where I am now. After the erase, the disk is basically unusable. iTunes alerted me saying that the disk "cannot be read or written", and Disk Utility will not verify, repair, erase, or partition the disk being that "the disk cannot be unmounted".
Can anyone tell me how to wipe this drive so I can bring it back to a "clean slate" state????
Thanks a lot,
Alex

You may have hosed the drive because iTunes unexpectedly quit while it was still writing to disk.
You should try WD support. Also,DiskWarrior may be able to unmount your disk, but run DW from the CD as there are installation issues on a 10.5 system.

ITunes 7 - problems with external hard drive

I installed iTunes 7 yesterday (I have Windows XP) but had lots of trouble. My iTunes directory is on my 'J' drive, so I changed the iTunes folder location in Preferences to my J:\itunes directory. Before closing iTunes I checked all my settings and they were correct. After closing iTunes, I went back in to see something, and it displayed the Setup Assistant again. Once it, I saw my folder location was back to the default C drive. I went through the process a few times and it kept reverting back to the C drive, each time giving me the Setup Assistant. I finally wound up uninstalling it and reinstalling a saved copy of iTunes 6, only, unfortunately, I lost all my settings and play counts because iTunes 6 couldn't use the files updated by iTunes 7. Anyone else have this experience and/or come up with a solution?

Thank you! The search turned up 4 libraries (two are "previous libraries). Of the non-Previous libraries, one is on the external where I expected to find it - in the iTunes folder, the other is on the c:\Users\Terry\Music.
Dates are what I expected for the approx. last access of the external library in march and newly created c:...
So I looked at the XML file for the iTunes Library and it has a hardcoded path of "F:\...." where I would have expected "G::\..." because G is where the external drive is. I'm comfortable in the Dos and Windows world, but not Vista. Maybe if I can remap the drive from G to F that might work. Problem is I'm not sure how to do that but will look and try it.
Thank you again for your help!!
