HAving trouble with external hard drive

Hey
i have a mac mini 1.83ghz intel core duo its about a year old now. I have a trekstore 160gb 2.5 external harddrive and for some reason it wont show up on my computer or the harddrive programm from apple. It worked fine for awhile and i was able to transfer all th data that i want to store on their as a back up and then one day i plug it in and it wont show up. Now this kinda ***** i paid 80 euro for the stupid thing have all m files backed up and its not showing up on my mac.
Any suggestions?

If you've got another Mac around the house or know someone who does, the next step would be to try connecting it to something other than the Mac Mini. If the drive works on another Mac, then there may be something wrong with the Mini; if the drive doesn't work on another Mac, continue being concerned about the integrity of the drive.
Also relevant for 2.5" drives, some of these don't come with AC adapters and instead draw power from the USB or FireWire bus. Though the FireWire bus can supply more than enough power to keep a 2.5" drive spinning, USB power is usually pretty measly, requiring either a complimetary AC adapter or a strange two-headed USB cable to draw extra power.

Macbook pro, trouble with external hard drives

I just got the drive on my mid-2010's macbook pro replaced at Apple. I am now experiencing a new problem.
My macbook is having trouble with ALL my external hard-drives. After a few minutes of being plugged in I click on them to open and the finder window is blank. Its not allowing me to veiw the content stored on the drive. If I keep trying my computer will freeze. I try to 'Force Eject' the drive and it doesnt eject so I have to unplug then start over.
This seems to happen roughly about 5 minutes after I plug them in. They work fine the first 5 minutes. Its becoming extremly annoying. All my drives are different makes, sizes, etc.. so I pretty sure its the macbook.
What might the problem be?
Thanks,
Shane

Trouble with external hard drive. help.

I was formatting my hard drive to allow larger GB files with a lot of trouble so I got my other hard drive which I have previously formatted to find the program that worked. It was formatted with NTFS so I downloaded NTFS 3G and restarted my computer (iMac intel) after trying to format my portable hard drive to ntfs the software didnt work so I uninstalled it. Now my external hard drive will not read on my iMac but it will on my TV and Windows computer. When I installed the software a little error message popped up but i made no changes to the external hard drive and now it wont read on my mac.
The hard drive is a Western Digital My Book 1TB

Did you read this section of the ntfs 3g website? I don't use the program but it may have left pieces of itself on your mac causing your current problems.
You can type the following in a terminal window to see what "non-apple" drivers are still loaded on your system.
kextstat | grep -v com.apple

New Apple User - Trouble with External Hard Drive

I am not very good with computers so hopefully this is a simple task. I just purchased my first mac, a MacBook for college. I bought a Seagate FreeAgent 160 GB drive with the intent of using it for time machine back ups and also for storing my music. I am wondering how or if this is possible.
So far I have:
- Transferred all my music from my PC to the hard drive no problem.
- I tried to set up Time Machine it said I had to delete everything from the Seagate drive in order to use it.
- I then copied all my files off of the hard drive to my Macbook's HD.
- Found out I also need to reformat my Seagate drive to Mac format.
Now I am wondering how to go about all of this and find out if its possible to store my music files on my hard drive as well as use it to for TM. I was thinking I can just move all my music back to the Seagate after TM erases it...would that work or is TM back-ups the only thing you can have on a drive?
Thank you!

Larko,
Generally speaking, you'll need an external hard drive with a capacity that is at least twice the size of the space being used on your internal hard drive. So, if you only have around 30 GBs of data on your new Macbook, you'll need at least 60 GBs for Time Machine. I'm going to state, though, that you'll probably end up using something more like 50 GBs on your Macbook's hard drive, so plan on using around 100 GBs for Time Machine.
Now, what you'll need to do first is format the external drive using Disk Utility (/Applications/Utilities/Disk Utility). In Disk Utility's "source list" at the left side of the window, select your external drive (not the named "volume" that will appear indented below it), then switch to the "Erase" tab. Erasing the entire hard drive will re-write the partition map, using the Apple "GUID" partition scheme (required for use with Time Machine).
If you want to store additional files on the external, that's OK. However, it is recommended that instead of storing both your Time Machine backup and your "personal" files on the same volume, that you partition the drive with 2 partitions. This will allow you to store the Time Machine backup in isolation on its own volume, and your "personal" files on the second. Disk Utility will handle this, too. Instead of erasing, switch to the "Partition" tab, use the pull-down menu to select 2 partitions, adjust the sizes according to your needs, then click "Partition."
I recommend that you size the first partition (for use with Time Machine) at 100 GBs, and the second with the remainder (which will end up being about 40 GBs).
You can certainly store that 10 GBs of music separately, but wouldn't it be best to import it into iTunes? If you do import it, or if it is kept on your Macbook in some other place, it will be backed up by Time Machine.

Trouble with External Hard Drive

I recorded some saved programs on my Dish Network DVR 622 to an external hard drive that formatted it for that purpose according to their instructions. Can the external hard drive now be reused by being hooked up to my HP notebook computer and reformatted or have I lost it because of that use? If so, how do I do it? I do not want to save anything on the drive--just format it and use it for a different purpose. I no longer have the Dish DVR. When I connect the external drive to my desktop I do not even see an icon for it in My Computer.
Thanks for any help.

OK with a little googling around I discovered the DISH DVR formats its external drives for Linux using the ext file system. Windows cannot natively read ext formatted drives. If you plugged it into a machine running Linux you could read the drive. There is also a Windows program that will allow you to read ext formatted hard drives right from Windows.
http://www.ext2fsd.com/?page_id=16
This may also be kind of a fools errand because I am also seeing that the movies on the hard drive may be encrypted and can only be read by a DVR running your account anyway. If you just want to wipe the drive right click on each of the rectangles in Disk 1 and select delete volume or delete partition until the whole box is blank then create simple volume and format it ntfs and you have a useable external drive.
You could also just delete one of the partitions like say the last one on the right which is 396.26 gb and then create a new partition in it and format it ntfs and give it a drive letter and then you would have a storage space for your laptop files. You could then keep the movies on the rest of the drive for when you get a new DVR. As I understand it from the DISH forums, when you plug the hard drive into a new DVR it will give the option to set it up to work on that DVR. Also I am not 100% clear that the external drives have encrypted movies. That may only apply to people who pull the hard drive out of the DVR and try to get movies from it.
This is an interesting project. The real easy way to see if the movies can be played from a PC is to make a Linux Live disk like ubuntu, boot the system from it and plug in the hard drive while you are running Linux from the Live disk. You could then see if you can see the movies and if they will play in the Linux media player program and it would not cost anything or change anything on your computer. Post back if you want more info on how to try that.

Trouble with external hard drive and disk repair

So I save my music and photos to an external hard drive. The drive is partitioned to also be the back up for my Time Machine. I live in an old house with the electricity for my MacBook Pro and the external hard drive coming from a wall plug which drapes scrape over when opening and closing, occasionally moving the plugs to the point of cutting off the electricity. Sometimes when that happens, the MacBook Pro won't read the external hard drive and I have to restart the computer for it to read the HD.
Well, this seems to have happened again, only this time it wasn't reading the HD when restarted. I Opened the Disk Utility and did a verify disk, and was told that I couldn't save anything to the drive, but to access the files that were on there. So I attempted to do a disk repair. What happens at that point is instead of getting the solid blue line indicating the repair is happening, I get the barber pole blue line indicating it's trying to access the HD to begin repair. This goes on for hours at a time without the repair taking place.
Can anyone out there give me a "for Dummies" overview of how to get the Disk Utility to repair things?
Thanks.

What I was trying to tell you is that all the music and photos that are on the same drive as your Time Machine backup must also be backed up elsewhere. Unlike all the stuff on your primary (internal) hard drive, those photos and music are not backed up at all unless you have copies of them on a different drive. If your Time Machine hard drive should fail before you do that, they'll all be lost. So copy all the music and photos to your second external hard drive as soon as you are able to do so.
I generally consider the nuisance of backing up extra hard drives to other extra hard drives burdensome and annoying enough so that I always upgrade my primary (internal) hard drive whenever I begin to run short of space on the one I'm using. Now that it's possible to get 750GB and 1TB internal drives for MBPs, I'll get one of those as soon as my present 250GB drive fills up to about 80% of its capacity. I don't want to lug around an external drive in order to have all my stuff with me when I'm away from my home or office — I want it all on my internal drive, and I want to be able to back all of it up at once to an external drive of the same or a larger size. At least until I outgrow a 1TB drive, and I think that will be a while.

Troubles with external hard-drive and iPad

Hi,
First post and all that. Thanks for taking the time to help me out.
I've recently bought my iPad, and while most things work especially well, one issue is really bugging me. The majority of my media is stored on an Iomega 1TB external hard drive, connected via USB to my computer. I'm running Windows XP and iTunes 9.2. When I hook up the iPad to the computer, iTunes loads, starts to sync the iPad with the music from the external HDD and suddenly I get a message saying "the device is not recognised" by the computer. The HDD has dropped off the radar. I've tried different things to get them to talk to each other, but to no avail.
Could someone help me please, to get my precious music off the external HDD? It's bugging me!
Cheers!

Thanks, I'll try connecting the HDD to the front USB ports and the iPad to the back. I did some more digging after posting here (my search-fu is weak!) and found a similar suggestion.
The HDD is indeed independently powered, so I wasn't sure of the power issue, but I'll check it out.
As to more info, the iPod Touch I have doesn't cause the same problems. And I can't transfer the media to the iTunes location, since that's on my first hard drive and I don't have enough space (hence the external one! :oD)
Cheers all!

Disk Utility and DiskWarrior trouble with external hard-drive.

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:
ile system

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.

I am having trouble erasing the hard drive in my Macbook Air

I am having trouble erasing the hard drive in my Macbook Air. When I enter Utilities and attempt to erase the buttons are frozen both security and erase

You need to restart with the Option key held down, boot from the computer's original thumbdrive(if any) or the recovery partition(10.7+), and erase the drive from there.

Issues with External Hard Drives

I hope this is the right forum for this one - please give me a steer if not! I've also posted it in 'Dock and Finder', but this forum seems equally appropriate, if not more so.
I'm getting repeated issues with External Hard Drives, including ones that I have been using successfully for months/years, suddenly failing to mount and then becoming 'unknown device' through the firewire branch of 'About This Mac'.
I've just bought a new hard drive on the grounds that the others had somehow failed, and the same problems are emerging. I decided to Repair Permissions on my iMac's internal drive, and am copying the results below, from repair runs conducted yesterday and today:

Permissions repair complete
My concerns are:
* Some of the permissions repaired yesterday appear to have needed to be repaired again today
* There are several files which carry a warning that they won't be repaired as they have been 'modified', and some of these clearly relate to disk management.
Does anyone have any ideas what is going on???
Thanks!!

Many problems with the 10.5.7 update have been fixed by a Restart.
If that doesn't help, something may have gone wrong with the update. Download and install the "combo" update, from: http://support.apple.com/downloads/MacOS_X_10_5_7_ComboUpdate
If that doesn't help, try running the Apple Hardware Test, on the disc that came with your computer.
1. Disconnect all external devices (including the Ethernet cable) except the keyboard and mouse.
2. Insert the "Additional Software & Apple Hardware Test" disc that came with your computer.
3. Restart while holding down the "C" key. When the list of available startup volumes appears, click Apple Hardware Test and the right arrow.
4. When the Apple Hardware Test main screen comes up (after a moment), follow the on screen instructions.
5. If it detects a problem, an error code will be displayed. Make a note of it.

Blue screen on start up with external Hard drive connected

On start up Imac freezes on light blue screen with external hard drive connected via firewire. Starts okay without hard drive connected. I have repaired the drive with no resolution of the problem.

You might try starting the iMac in "verbose mode" by holding down command-V when booting:

That could show you some messages that might explain the problem.
Another approach is to launch the Console utility and look for messages dated around the time of a hang.

Synching iPhone with external hard drive

I recently got a new MacBook Pro. For some time, I've been storing all my iTunes music on an external hard drive with no issues.
I was having trouble synching my iPhone with the new MacBook at first. It was telling me it would need to erase the current music from my phone. Finally I realized I needed to copy the iTunes folder from the user Library on my old Mac. Then I was able to synch my phone.
BUT then I realized that, rather than accessing the music on my external hard drive, iTunes had copied all my music to the new Mac's hard drive. So I looked it up and got it to recognize the external drive -- ended up having to copy all the music from the Mac BACK to the external drive, where it already existed.
But now the phone won't synch again! Those files are still in the Library folder. Why is the Mac treating my iPhone like a stranger again?

But, as I said, by copying those files from the /user/Library/iTunes folder, I had solved the problem temporarily on the new computer. Now that it's looking for the music on the external hard drive, something is messed up again.
And, by the way, the music is still all on the internal hard drive, too. But I did do the "consolidate library" and I've verified that iTunes is finding the music on the external hard drive, not the internal one.

ITunes won't sync correctly with external hard drive

I have long kept my music on an external hard drive and had absolutely no problems with adding files to my iTunes library. Whenever I added songs to iTunes, they would automatically be copied over to my external device (a Seagate Freeagent 1TB USB External Hard Drive) everything would be fine. I could erase the song data remaining on my notebook without any problems.
But, after recently upgrading to Windows 7, I'm having some trouble keeping everything organized. I did a clean install so I had to reinstall iTunes, and upon doing so I specified for it to access my library from my external device like before. It does that just fine, but when I add songs to iTunes, they don't copy over to the hard drive, and when I consolidate the files, all of my songs get copied onto my notebook hard drive.
Is there a fix to this? Something I skipped when telling iTunes where to get/keep my music? I want to be able to add songs to the library and have them copy directly to my external device.

Hmmmm. By any chance, do you have 4 GB of RAM and an NVIDIA USB EHCI chipset on the Fujitsu? If so, perhaps see the following Microsoft document:
