External hard drive not recognized, or recognized as RAW

I have the Pavillon desktop running Windows 7 and have been having trouble with my computer either not recognizing Seagate 2 TB external drive, or if recognized, it is listed as Raw. I have:
1. Connected the drive to my laptop - it worked fine;
2. Changed the USB port on my desktop, over and over, same problem;
3. Reformatted the drive, same problem;
4. hooked it up to a different outlet, same problem;
5. Run the delivered HP hardware diagnostic tools, no errors noted, but same drive problem persists;
6. Updated drivers, over and over.
Is there ANYTHING else I can try?

Time Machine is causing my external hard drive not to be recognized or read

I have been using Time Machine on my MAC. I don't like it. I now have gone into preferences and stopped it from further backups. Now, I want to restore my Toshiba External Hard Drive and have it backup. When I look into my Macintosh HD, it does not "see" the drive. It doesn't appear in Finder. I am assuming that Time Machine configured it or reformatted it? So, how do I get it "back" from Time Machine? One person commented that this is an issue of formatting my hard drive, but the problem started with Time Machine. Where should I post this question, if not here?
Thank you!

I'm guessing that Time Machine hides it from Finder as most users aren't going to want to be mucking around in it. Try opening up Disk Utility and see if you can see it. You can reformat it from there as well.

LR 5 does not recognize my external hard drive. It has recognized this drive in the past. No help at any Adobe site.

My external HD contains photos I have worked on in the past.
Additionally, I have added photos to LR5 directly onto my Mac HD. (38
photos added when working in the absence of my external HD)
Presently, in the Library mode, the Le Cie external HD is not seen in the
upper left hand corner "Source" location.
The only way to "see" the La Cie HD and its photos is in the "Import" mode.
These photos have previously been imported.
I wish to use the La Cie HD as my source in the Library mode and proceed to
the Develop mode.
In other words, work on my previously imported, previously worked on
photos, now on the La Cie.

I fixed mine by uninstalling the software that came with the harddrive such as Tuxera and reinstalled it now myharddrive works again and i did not have to delete the harddrive and reformat it.
I tried a lot like reseting the Pram And connecting other harddrives but by unstalling the original software it works all over again. I hope this works for you because i was getting pretty frustrated myself.

I am planning on using my time capsule as a network and essentially an external hard drive - not just back up, is this ok?

I am planning on using my time capsule as a network and essentially an external hard drive - not just back up, is this ok?

Most users should use the Time Capsule for backups. This assumes that "original" copies of your data are on the computer and backups of this data are stored on the Time Capsule.
If either the Time Capsule or the hard drive on your computer fails, there are at least copies of your important data on the other drive.
If you are asking if you can place "original" files on the Time Capsule, do you have a plan to backup those files?
If the Time Capsule drive has a problem....and your only copy of your important data is on the Time Capsule....you will lose everything.
If you are asking if this is OK, the answer for most folks would be "no".
Can you clarify if this is what you are asking?

Why is my External Hard Drive not showing in Aperture 3.6 Import?

Why is my External Hard Drive not showing in Aperture 3.6 Import?
Only my computer hard drive is and I want to import from an external drive. I have always been able to until I updated to Aperture 3.6 and Yosemite.

Only my computer hard drive is and I want to import from an external drive. I have always been able to until I updated to Aperture 3.6 and Yosemite.
I had the same problem. On the folders on the drive with the Aperture library did show in the Import panel. After I clicked the computer icon in the upper left corner of the Import panel, suddenly all drives appeared.
You can also try to drag the folder you want to import into the Import panel, to point the file chooser to the drive.

I can't import my movies to work on them. They are coming from a external hard drive, not directly from the camera, its type mpeg-e (.mts)

My movies are type MPEG-2
I can't import my movies to work on them. They are coming from a external hard drive, not directly from the camera, its type mpeg-2 (.mts)
What can I do ?

1. Is your external HD connected by firewire?
2. mpeg2 is the final compressed delivery format of a DVD, not intended for editing, and iMovie cannot handle such files, so you need to convert them first:
For that you need mpegStreamclip:
http://www.apple.com/downloads/macosx/video/mpegstreamclip.html
which is free, but you must also have the Apple mpeg2 plugin :

which is a mere $20.

External Hard Drive not recognized.

Hello everyone,
I have a probem where my external hard drive is not being recognized by my late 2009 iMac.
The hard drive is an OWC Mercury Elite-AL Pro connected to the firewire port.
It was working fine till this happenend:
I keep all of my iTuned music on the external hard drive.
I was using a meta tag fixer type program.
I dragged the files from itunes into this program (Tune Up) to fix the meta tags.
However, I missed the program and dragged thusands of .mp3 files onto my desktop.
My computer, of course, became unresponsive.
So I used the power button on the back of the iMac to shut it off.
I used my MacBookPro to connect to my iMac as a target drive, and deleted all the .mp3's from the desktop there.
Once I restarted my iMac everything was fine, except that the external hard drive has not been able to be recognised ever since.
The same drive shows up just fine on my MacBookPro.
Help!
Thanks!

I had the exact same problem! I had to force shut down my iMac (24in, Mid 2007) due to a system freeze. After restarting, everything was working fine, except for my external 1GB G-Drive, which was connected through FW800 port.
The drive connected fine to my MacBook Pro, but it would not be recognized by my iMac. I tried restarting, but neither Disk Utility, nor System profiler would see the drive.
What worked though, was Resetting the System Management Controller (SMC):
1.          Shut down the computer.
2.          Unplug the computer's power cord.
3.          Wait fifteen seconds.
4.          Attach the computer's power cord.
5.          Wait five seconds, then press the power button to turn on the computer.
The drive mounts fine now. I am surprised this is not mentioned by Apple in their support documents! It has happened twice to me and it was the only thing worked both times. The link for the resetting the SMC is here:

Hope this helps solve your problem too.

External hard drive not recognized... help please.

okay, well here is the story:
my iBook G4 had its stock 30gb hard drive in it and it was running extremely low on space. so i figured i didn't want to carry around an external hard drive, therefore i would buy an internal hard drive an install it. so i purchased a new 2.5" 80gb hard drive and called up the local apple store. they told me that although it was under warranty, that it did not cover hard drive installation. so i looked it up online and found step by step instructions to install the hard drive. so after lots of hard work and many screws, i installed the new hard drive successfully... but i still had this perfect 30gb hard drive. i thought maybe to save a few bucks i could turn it into a usb external hard drive. i found an enclosure for the hard drive and a usb 2.0 cable and plugged it into my ibook. it was recognized and everything. i put some files on the external hard drive and transferred it to another mac. this is where the trouble started. i plugged the hard drive into a PowerMac G4, and it was not recognized... so i tried it on a different mac. this time on a PowerBook G4, but no luck. this issue has been troubling me for a few weeks. but then i tried it on a similar iBook G4... and it was recognized. but i don't know why it was only recognized only on the iBook G4 (not the same iBook G4 it was pulled out of) and no other macs.
does anybody have any ideas what we can do to get this hard drive to be recognized by other macs?
any of even the smallest ideas would be greatly appreciated.
thanks,
tyler

I can walk you through formatting the hard drive:
1. Hook it up to an iBook that recognizes it.
2. Go into your Applications folder, then scroll down to Utilities. Open Utilities and scroll down a bit and you should see Disk Utility. Double-click.
3. On the left side you should see your internal hard drive and your external one. Each hard drive will have a sub-catagory with the partition indented.
4. Your external hard drive will probably be the second catagory. Click it.
5. In the center-top you should see the tabs First Aid, Erase, Partition, RAID, and Restore. Click the Erase tab.
6. You should see Volume Format: and then a drop down menu, and Name: and a text box. Type in the name you want the external hard drive to be named.
7. In the drop down menu, select Mac OS Extended (Journaled).
8. Then, simply click Erase, watch the progress and it should be good to go!!
Hope I helped you out. Oh, and it might be the enclosure...and also what OS's? Since it's USB it is probably using a USB Mass Storage driver. Mac-wise, if formatting doesn't help, I would get a FireWire enclosure because FireWire is much faster than just USB 2.0. Oh, thats nother thing...Is the enclosure Hi-Speed USB? If it isn't, I would definitely get a FireWire one...If it is, the PowerMac G4 doesn't have Hi-Speed so you're not taking full advantage..Just some insight

External hard drives not being recognized by Lr4

When I hooked up my two external hard drives to my computer this week, Lr4 is not recognizing them. Each folder has a question mark by it.
Appreciate any help..thanks!

Hi Jim,
I spent some time doing maintenance on Lil's computer. We were on public networks for 10 days and so I ran some cleanup software to help ensure that we don't have some virus or other malware messing things up.
Then I did some comparing and it appears that Lightroom has the G and H drives reversed.
I have enclosed 4 screen shots. Two show the strong(but not perfect) correlation between LR drive G and Explorer drive H........and vice versa. Another shows the K drive and the fourth shows the G drive one level up as you requested. I believe that when we disconnected this computer to take on vacation that we just pulled all the plugs and did NOT take any steps to "logically" disconnect them. If LR is sensitive to drives just being removed by pulling the cable, then perhaps that contributed to this situation...although I believe that we used the same procedure in the past.
Thanks,
David Polley

External Hard Drives not being recognized

I have 3 external hard drives. Had them for a long time now. I recently made only one change: I decided to start using the 'sleep' mode.
I noticed the sleep mode and external hard drives didn't get along real well, so I simply took the externals (used only for backing up data) and turned them off.
Its now been about 2 weeks, time to fire them back up and backup my data. Only one of the 3 is being recognized. The other two seem to come on, make the usual whiny noise and such, but aren't seen in the finder.
I've tried restarting my computer, turning off/on the hard drives, unplugging/replugging them from power, unplugging/replugging them into USB. I've verified connections, that kind of thing. Nada.
Any ideas on what to do to help my computer 'see' that they are there? this is a bit baffling to me and disconcerting, to say the least. I've never had problems with my computer recognizing the externals before.
Ideas are appreciated.
PowerMac G4 1.42 duel Mac OS X (10.4.6)

'sleep mode' ?
Do you mean the drives are triggered to not spin up for a period after powering on ? This is a feature designed for enormous banks of drives, so that when they are powered on, only a fraction spin up immediately, then another set, usually 12 seconds later, then another set, etc, until all are up to speed. This is reduce the power surge from spinning up 700 hard drives simultaneously in a commercial solution.

Toshiba External Hard Drive not recognized by computer. Please help!

I was wondering if anyone could help me. I have an external hard drive and it will not show up in "My computer" when I plug it in. I have tried other USB drives and other computers. I am starting to think it is a hardware issue but I don't want to lose hope. The blue light is coming on when you plug it in but it doesn't blink and there is no noise whatsoever. Is there anything I can do to fix this issue so that I can recover the information on it? Thanks in advance for any help. It is greatly appreciated.
Additional information: I'm not sure how old this thing is but the model number is HDDR160E03X.

Same problem: I can't see my Toshiba PH3100U-EXB (Gen 2) external hard drive when I plug it in. After awhile I get this error message (see attachment): USB Device Not Recognized. One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it. FOr assistance in solving this problem, click this message."
When I click it, I get a list of USB ports and devices, with Unknown Device in bold face. No real information there.
Yes, I ran Disk Management and the Toshiba did not show up when I plugged it in and hit Refresh.
Does it make a difference that the last time I used the external hard drive, we were in Windows XP and now we're in Windows 7?
Please help! It's not just the backing up I'm worried about...it's being able to retrieve files later!
Thanks!

External hard drive not recognized in Finder or Disk Utility

Two weeks ago, my 2007 black Macbook stopped recognizing the hard drive. I was told by some IT friends that the controller had likely failed and I needed to purchase a new laptop. I removed the hard drive and placed it into an enclosure (turning it into an external hard drive) and hooked it up to a new Macbook Pro which I purchased a couple days ago. The external hard drive did not show up in Finder or Disk Utility but the light on the enclosure was on and it was making a very soft whirring noise and got warm after a few minutes. I usually backed up the hard drive but, of course, hadn't done it in a couple of weeks before it died so everything I worked on in that time is lost to me at the moment. I'm trying to avoid paying tons of money for a data recovery service so any advice would be greatly appreciated! Thanks!

That whirring noise might be due to physical damage on the disk. I know data recovery services are costly but that remains only the solution for damaged HDD. You can get latest quotes on services from different dealers. Proceed only when your data is very important to be recovered.

External hard drives not recognized by imac

I am a new Mac user and have been having lots of trouble getting my external hard drives to mount. I have a simpletech and a seagate external hard drive both NFTS formatted neither of which is recognized by my iMac. They don't show up on disk utility or system profiier under USB ports. They both work on my PC laptop and a friends iMac (OS 10.6.4) just fine. I have a card reader and flash drive that work perfectly on my iMac. Apple support orginally thought it might be the logic board so they replaced it. The new one is having the exact same problem. Does anyone have any idea what could possibly be the problem?? This is driving me insane.

I'm having exactly the same problem with a new iMac purchased one week ago. I have two Maxtor drives and one WD, all firewire 400 drives, all of which mount briefly and then unmount and will not mount again. I am not new to Macs. The drives work fine on the older PowerPC Mac running 10.4.11. These drives contain my backups and aren't recognized by the new iMac. I cannot believe that 3 external drives are all going into failure mode at the same time since they were all purchased at different times and only used as backup drives, so they weren't on all of the time. Is there an incompatibility between 800 and 400?? I'm using a LaCie 800 to 400 firewire cable. Suggestions??

Now, USB External Hard Drive Not Recognized after 10.6.8 Update

My external Hard Drive is not recognized on start up. I have to unplug it and plug it back in for it to be recognized.
All this since 10.6.8 updated today.
I'm a fool for updating the same day.
This has happened before and I always forget the bugs in the software when it first comes out.

Alright, I'm gonna go ahead and close this thread. I found out the solution to my issue. Turns out it was a problem with a system file I changed right before installing. The error only occurred on a restart... the required 10.6.1 reboot was the first reboot since the change, so thus it looked like the culprit.
If you want a more thorough explanation of my problem (highly HIGHLY doubt it's gonna help you guys out), check this thread --> http://forums.appleinsider.com/showpost.php?p=1480362&postcount=8
Sorry for the trouble!

WD external hard drive not recognized after improper eject

I have a WD Passport external hard drive that I've been using for a while with my MacBook Pro. The cord got yanked, causing the drive to improperly eject. Now my computer isn't recognizing the HD. Help! Of course EVERYTHING important is on this drive!
I tried plugging it into a Mac desktop, which also did not recognize the drive.
I plugged a different Passport into my MacBook Pro, and it was recognized, so I know it's not the USB Port that's causing the problem.
I used the cord from the HD that mounted with the problem HD. Didn't mount with the new cord. So I know it's the passport that's causing the problem, not the MacBook, not the USB port, not the cord.
I ran the disk utility, and the HD does not appear...It is powering up though- the light on the HD is lighting up. Oh please help!
Did I kill my disk? Of course I just moved my entire iPhoto library to this location, and I haven't backed it up yet....

No. It may just require a 00 Phillips driver depending upon the enclosure. Do the swap on a towel so that the little screws don't bounce away from you. You will have to pull the HDD out from the connecting plug. Do it in a straight line,don't bend it, and you may have to slowly increase pressure to get it out of the connecting plug.
It's not rocket science.
Ciao.
