Attaching USB External Drive Results in Error Message

I hope this is the right forum to seek help on this issue, and I hope someone can help...
I have a 500 gig external hard drive hooked up to my AEBS. Because the issue I describe at the forum topic below continues, I access it by going to the "Go Menu" and choosing "Connect to Server."
http://discussions.apple.com/thread.jspa?threadID=1255400&tstart=0
Yesterday, I tried to connect the drive directly to my Macbook Pro, and it did not appear to mount (normally a little globe icon would appear on my desktop, this time it did not.) So I navigated to "/volumes" and found what appeared to be the icon I was seeking that would allow me to open the drive. However, when I try to open it, I get the following error message:
"500 gig could not be opened because the original item could not be found."
At that point, I have 3 options:
Delete Alias
Fix Alias
Cancel
Attempting to delete the alias results in a message stating I do not have sufficient privileges for such a maneuver. Attempting to fix the alias puts me into my finder/file directory as if I'm supposed to navigate to a file.
Other interesting fun:
* The drive appears in Disk Utility when I plug it into my Macbook Pro, and I can mount, unmount, and eject it there.
* In Disk Utility, it says that the file structure is "Mac OS Extended (Journaled)" - which is how I formatted it when I first got the drive and plugged it into my Macbook Pro.
* When I "get info" on the icon in "volumes", it says that the owner is "system."
* When I connect to the drive via AEBS and choose "get info" on the icon, it says that it is formatted as "windows file sharing."
* My privileges when it is routed through my AEBS say I can "Read & Write."
I have searched this error message on the 'internets' and in this forum, but the hits I encounter seem to involve connecting to Windows servers with a Mac.
As you can probably tell, my level of computer knowledge is only about enough to get me in trouble. Any help or direction is appreciated..

Never found or heard an answer for this. Since I could access the drive wirelessly through my router, I ended up copying everything over to my laptop (50+ Gigs - took HOURS), and then reformatted the disk with Disk Utility. I can now access it by hooking it directly into the laptop. I'm now moving everything back and setting this topic to answered.

You need something stronger, such as DiskWarrior, TechTools Pro, or Data Rescue.

My external LaCie drive gets an error message "the disc you inserted was not readable by this computer." The only options offered are "ignore" or "eject" Disk Utility sees the disc but does not give a repair option. What can I do?

The good thing about mac-centric resellers such as OWC, is they have people on staff that can answer questions without you buying things first. They also have how-to information, and instructions are included in many of their products. I saw a link to watch a DIY video in one of their pages; an example of a RAID (with its own power supply) is shown on their drives page. Also a few in there, with no power supplies, for less money.
If I were looking to backup and perhaps also have a partition for a system clone, I'd consider something like one of these: http://eshop.macsales.com/shop/firewire/1394/USB/EliteAL/eSATA_FW800_FW400_USB
Some ideas on the RAID backup methods appear in google search, some of the pages are ideas and concepts; and the better ones also warn about using RAID for the only backup plan.
Oh, OWC has live chat. Haven't tried it, nor have I bought anything from them. I have what appears to be two products from them, but have not used either. One is in a box as-new, but has only USB2.0 ports & my Macs needed FW400/800. It has been said their RAM is a good way to upgrade, too. But I can't confirm!
A 'RAID-ready' unit for backup may be more versatile for just that, but I have not checked into these details. I use single HDDs in powered enclosures, and usually manually make backup clones to FW drives, of bootable OS X systems. Some of the OWC raid-ready use eSATA ports so that may not be viable for a computer without them.
The unused in-box external drive I have is like the base model in the link above. However mine is USB2.0 (maybe) and won't boot my older Macs due to hardware variance; and my preference would be for FireWire options, these models do offer that. But the one I have does not. Dual 500GB HDDs, and they could be used in tandem as a RAID. That would be a choice set up in software. I'm not sure and not interested enough to read up just now.
My backup method is not automatic, or a moving backup plan, if I don't get a move-on and make full system clones. I do make copies of photos and documents the manual way, to USB external drives; and occasionally backup to DVD or CD media. And USB flash, that helps to move files between computers without need to use file sharing via wi-fi. {Like Why fly? Walking is better exercise unless one is a bird. Squawk!}
https://www.google.com/#q=raid+backup+mac
Depending on the ports in your Mac, you may be able to use other cables to attach between a backup or externally enclosed hard disk drive with multiple partition and bootable clone in one of them. Not sure about the Thunderbolt, and where that is the main port, adapters are required to access other devices, as allowed.
Anyway, I am going on and on, yet not really saying anything.
My ideas would not be all that interesting to follow as a backup
plan when matching available newer hardware to task, but you
can get some into better ideas if you are not in a rush. Get a
good setup and then look into more an betterer stuff.
Good luck & happy computing!

Kernel Panic when attaching time machine USB external drive

Really hope someone can help me with this.
I've got a late 2011 Macbook Pro, and was running Time Machine on a 500GB GDrive USB external drive. Was working fine when I last attached it on Feb 29. The Time Machine backup was encrypted.
When I tried to use it yesterday, as I have lost all my iTunes data on another drive, I got a Kernel Panic when I entered the password for the drive.
I managed to de-encrypt the drive using Disk Utility, but now I get a Kernel Panic everytime I plug the **** drive in.
I really need this backup data, would appreciate any help people can offer. Am running Lion 7.3, and the same error occurs on a Lion iMac that I have tried the drive on.

How do I view and open all my files again that are on my external hard drive?? Error message saying 'The disk you inserted was not readable by this computer' Three options are Initialize, Ignore or Eject.

I have recently purchased Toshiba 1TB hard drive and I set it up and I was able to transfer all my files onto it such as my music, photos, documents. I had correctly ejected and used it again and all these files were safely stored and accessible afterwards. However after I rebooted my computer as it had been going slow and I had too much clogging it up once I reconnected the external hard drive I have error message saying 'The disk you inserted was not readable by this computer' Three options are Initialize, Ignore or Eject. How do I access all my files? I set it up to work on both mac and windows. I have tried both another mac and windows computer and same issue occurs?? I am worried that all my personal files are gone but am confused as the drive has had absolutely no damage to it as it was in a very short time frame and its never left the same spot. Any help would be greatly appreciated. Thanks

Thanks for your quick response. I had a look at your discussion... I tried it on a Windows machine and I thought that was compatible with ExFAT?
Therefore I need to attempt to use my external hard drive with a machine that boasts OS X 10.6.5 or above and then it should work?
Thanks

Trying to move aperture library from USB external drive to FW 800 external drive.i can see the projects but no thumbnails. Error application not responding. Verified permissions before started. It's been 3hours. Recommendations please

I have consolidated iPhoto into aperture 3.2.2 and now have both aperture and iPhoto put consolidated library on 2.0 USB external drive. Have been removing duplicate photos from 23,000 down to 15,000. Problem in trying to close aperture and now tried to move library from 2.0 USB to 800FW and can see projects but no thumbnails. Aperture error now reads not responding. Can I repair library on 2.0 at this point?

Sharon,
did you do anything else besides copying your library to a fire wire drive after your last post Aperture not responding ?
Since that library probalbly already needed fixing, I'd recommend to force quit Aperture and use the "First Aid" to repair your Library.

USB external drive not readable by mac but readable by windows

Hi, I have a usb external drive (Seagate FreeAgentDesktop Media) which works fine with windows xp but cannot be read by the mac. I reinstalled the mac a couple of days ago because it was being very slow and I had a bunch of junk on it. Anyway, after that, it won't read the external drive. It will give me an error message saying that the disk is not readable by the computer. Sometimes it will give me the message saying that the drive was unmounted improperly by windows and for me to unmount it correctly. When I go back to windows, it's there, then I restart and go back to mac, it'll give me the message that the disk is not readable. I have 2 of these drives and both of them have this issue. I also tried disk warrior but it says that the file system cannot be rebuilt. I tried USB flashdrives and they work. I got all the data off of one of the external drives into the other and I couldn't format or even erase the drive because it says that the permission was denied. However, I could format it and erase it with the installation DVD. But I had the same result no matter what format they were in. I have very important data on these drives and I really need to be able to use them with both operating systems. Thanks a lot!

Hi Schmerz Meister;
If DiskWarrior say it can rebuild the disk about your only other alternative it to reformat it.
This will of course destroy all data on the disk so make sure you have copies of the data elsewhere,

WD My Passport 1TB USB external drive randomly ejects from my iMac and MacBook Pro.
The drive is approximately 4 years old. When the drive is plugged in, I can see the data. It appears to be working properly. The only problem is that everyone of my Apple Machines are ejecting it. Several years ago, this drive connected to Mac machines with no problems. I have tried two separate USB cords. I have updated the firmware. I have tried it on my MacBook, two different Macbook Pro's, and my iMac.
All give the same result of random ejection of the drive and the error message of:
Disk Not Ejected Properly
Eject "1TB Passport HD" before disconnecting or turning......
Searching through the web, it seems this is an common/known problem. Does anyone know the solution?
Thanks,

Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.

USB External Drive Backup & Erase Woes

I have been using a Lacie 500GB USB external drive allocated as a backup disk for time machine. Over the last couple of weeks, the disk has been spontaneously ejecting itself from the desktop. This could happen when not backing up to time machine, or during the backup.
I am not a daily time machine backup-er, as I don't have much to backup on a daily basis (and I weekly backup to an alternative disk using Super Duper). What I had noticed with the time machine disk, is that the preparation prior to the backup beginning was a massive 40+GB, certainly not the amount of data which would have been 'new'.
To try to resolve this, I have used disk utility to verify the disk, and the snow leopard disc to check my boot disk on the Macbook Pro... there has not been a problem identified with either.
Today, I decided to erase the time machine disk, zero the data, and re-allocate the drive for time machine backup. After setting these preferences in disk utility, and clicking 'erase', the disk again erased itself, with the error message :
'Disk erase failed with the error: Assert: internal error, or unimplemented'
I then had an external disk which was not present on the desktop, and apparently in some sort of limbo between erased and mounted!
I was able to do a simpler format function on the disk via disk utility, the disk will mount, but the allocated disk space previously used by time machine is still present, and the format has only done that remaining space on the disk.
Anyone know what the above error message refers to, am I able to reformat the disk using the 'zero function', or has the disk failed and become unrecoverable?
Answers / suggestions kindly welcomed.

Welcome to Apple Discussions.
When you use Disk Utility to erase totally you need to click on the LaCie drive name not the name that appears on the desktop. Select how many partitions you want and give each partition the name you want it to have and perhaps also the partitioning scheme and other options that are available, then erase.
Doing this will of course make all that is on the drive unavailable to you.
These are LaCie's directions for their drives.
Some LaCie drives might also have firmware updates available - worth a check on their website.
Note that LaCie seem to have 2 yr warranty on their drives, at least the one I looked at on their website. If the drive is younger than this you might have a warranty claim.

MacBook Air USB external drive power source

I have a LaCie 250GB USB external drive on my MacBook Air and the computer is not being able to power the drive without me connecting the hard drive to an external power source. when the drive was had about 80GB of data it would do it, now that the drive has about 180GB of data, it does not work. Can anybody recommend a solution or an external drive that can hold at least 250GB that can be powered by the MacBook Air without need for external power source?

I have the same time of problem. Although, it's mentioned a using a self powered hub. However, I find this did not work. Apple states that the single usb port on the MBA is high powered to give the ext. super drive they sell the power it needs to connect to the MBA. What I have noticed is no matter which USB self powered hub I use I get the same results. The MBA reports that one or more devices is drawing too much power. Although, the powered hub is supposed to provide power to those devices that require power over USB. I should also mention, all I am connecting are two USB devices. 1 ext. Verbatim 500 Gig Drive. and my iPhone. Since the MBA has only 120 gig drive I had to move all of my movies etc. to the Ext. 500 now if I want to sync my phone or move a movie to the phone I get the errors.

I cannot upload my iMovie video to Facebook, etc. I cannot even attach it to an email, an 'error' message comes up when almost complete. It plays fine in imovies, VLC, mplayerx. Confused, is the file damaged somehow?

The Deskjet series printers connect to wireless networks with what is called USB to Wireless.
You will need a supported operating system to connect a Deskjet to a wireless network. Supported operating systems to connect the printer to a wireless network are Windows 7 (32bit and 64bit), Windows Vista (32bit and 64bit), and Mac OS X (10.5, 10.6, and 10.7).
While there is a software download option for Linux distributions, this is not the full featured software that is capable of adding the printer to a wireless network. Most printers have a wireless setup wizard to accomplish this task, but the Deskjet series printers connect in a different way.
Once the printer is connected to a wireless network, HPLIP 3.12.4 drivers should be able to locate the printer.
Click on Installing the Product Software for a Wireless Network Connection to receive instructions to connect to a wireless network using Windows and Mac operating systems.
Click on Software & Driver Downloads - HP Deskjet 3070A e-All-in-One Printer - B611a to download the appropriate software for a supported operating system to connect to a wireless network.

USB External Drive Trouble

Back in April, I hooked a 500 GB USB external drive to my iMac in order to run time machine. All worked fine until October 17. Yesterday Time Machine popped up with a message telling me it had not backed up in 10 days and I should figure this out. At this point, I noticed that the external drive was no longer mounted on the desktop, although I could see it in Disk Utility. The POSIX error came up. After a long search on the forum and fighting with a PC in the house, I was able to reformat the drive and let Time Machine do its thing.
The initial backup went great and it seemed to back up every hour until 12 am or so it says. Once again, I came down this am and the drive is not mounted and not showing in Disk Utility. I turned it off and on again and now the computer tells me it needs to be initialized.
What in the world is going on? Is it related to USB control and SL? Is it a Time Machine issue? Should I reformat the drive and see if I can simply copy files to the drive and see if it stays mounted that way?
I do not know how to tell an external drive when to unmount or if it should upon the computer going to sleep.
Any help would be greatly appreciated before I spend more money on a new drive.
Debbioe

Thanks, that one's not on my suspect list... yet
Good luck with the replacement, I'm sure it will be fine. When you get it remember to format for Mac OS X.
1. Launch Disk Utility
2. Click the "Erase" tab
3. Select your entire external drive on the sidebar (the uppermost icon).
4. Format: "Mac OS Extended Journaled"
5. Name the Disk (Time Machine, or whatever) only the name of the volume will show in Finder.

MDT 2012 deploy OS from USB external drive failed - need to unplug and plug it once again

We are using MDT 2012 and deploying Windows 7 using media (USB external hard drive). We can successfully deploy Windows 7 32 bit using this method but there is a problem with deploying Windows 7 64bit. This problem appears only on HP EliteBook 840. We can
boot into WinPE 64 bit and can start proper task sequence, all image is applied then after restart, before logon screen appears there is an error saying that cannot find litetouch.vbs script. After clicking ok, I can logon to Windows and there is no usb external
drive recognized. But when I unplug and plug usb drive once again it is recognized by Windows and can be used. I can see that Windows install some drivers just after plug it again
I checked BIOS looking for some USB power options - there is no such settings. And 32 bit deployment works ok. So this is not a case. Looks for me like a problem with proper usb drivers for 64 bit. I download all drivers from HP website (driver pack and
drivers only for USB 3.0). We are using make and model matching in MDT - works ok for all the rest hardware models. Any idea how to troubleshoot it?

Not sure what's going on here. Is this a USB "Flash" drive or a USB "Hard Drive". There *Is* a distinction.
I *thought* that MDT would copy itself to the c:\minint\scripts folder to continue installation.
Next time, when you see this error, Press Shift-F10 to get into a cmd.exe prompt. Can you find litetouch.vbs on any of the drives? Does the USB Drive appear?
IF in fact, the USB Drive is not appearing after the 1st reboot, then you have a problem. Why did the USB 3.0 driver not install. Check the Driver Installation Logs to verify.

Unable to charge my Ipad 4 with my Laptop (HP 7010tx) USB . I am Getting error message as "Not Charging" . Please give a solution for this ...???

The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W (5W on Mini) USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (2.5W, most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
How to Calibrate Your Mac, iPhone, or iPad Battery
http://www.macblend.com/how-to-calibrate-your-mac-iphone-or-ipad-battery/
At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.
