Seagate portable drive not being recognized after OSX10.9.2

After I installed the 9.2 update, my Seagate portable external drive is not being recognized - doesnt show up in Finder, or Disk Utility, but I know the drive is live, as I can feel it vibrating
Someone please help, all my time machine backup is on that

I had the same issue - the Seagate drive is in a format that will recognize both Windows and Mac formats and there seems to be a flaw with Seagate. After working on this for five hours and finally calling Apple, I found out why. If you reformat to Mac OS extended journaled then they usually start working properly.
When I contacted Seagate they said it was best if you are just using a mac to just use the Mac formatting.
Hope this helps and good luck. Hope there wasn't any valuable data on the drive.

Acomdata 500gb External FW Drive NOT BEING RECOGNIZED!!!

I have been running an Acomdata 500gb FW External Hard Drive for my data intensive applications such as FCP and it has been working flawlessly for about the last year...
Yesterday I powered up the Mac and turned on the drive along with my external USB drive and the Acomdata drive turns on, lights up, and makes noise like it's working, but it is not being recognized at all by the Mac. I tried unplugging it, switching out the FW cord, changing the FW slot it was being plugged into, and everything else of that nature that I could think of. Of course the USB drive that has non-important work related stuff works just fine :/
So I'm wondering, does anyone think the drive has officially crapped out? It turns on and works so I can't tell. I'm PRAYING this is not the case, but I didn't know if there were any possible FW configuration settings that could have been changed or something like that. Any ideas?

Did you recently update to 10.4.10? Is there another computer that you can plug the external into to see if it's recognized? Have you tried plugging another FW peripheral into your main computer to see if it recognizes it?
Some people have had good results from the following:
1. Downloading and installing the combo updater of the system software update they've just applied via "Software Update...". In your case the update you need is at:
10.4.10 combo updater
2. Another trick is to restart each by zapping the parameter RAM:
Zapping the P-RAM:
After the startup tone, hold down <commandd><option><r> until 3 additional startup tones are heard, then release the 4 keys.
3. A 3rd tip would be to do Open Firmware resets on each:
After the startup tone, hold down <command><option><o><f> until the text screen is visible. When text can be entered, type the following commands, followed by the <return> key (there are no space characters in each command):
reset-nvram
set-defaults
reset-all (the Mac will boot up after this command is entered).
Also, see if anything in this Apple KB article helps:

Hard Drive not being recognized on my Graphite Clamshell

I have a challenge for anyone. I have a ibook 366(clamshell) that is not recognizing the hd. It was working wonderfully one night I shut it down and the next day I get the flashing question mark. I've tried all of the normal stuff: zap pram, reset nvram tried to use command and s but it didn't go to the programmers screen and all the such. I can boot from a cd but none of the utilities see the hd. I have taken the hd out and connected it to a usb to ide cable that allows me to use it as an external drive and it is recognized without any problem on all of the other macs I connect it to and even on a pc (I know I said the bad word.)Does anyone have any clue what could be the issue. Every thing else seems to work fine. Just the hd is not being recognized. I even put in a different hd. I even formatted the drive using one of my macs that I only have 9.2.2 on and installed a os on it and it still didn't work. The hard drive worked fine and the os with all of its components seemed to be fine. I know it's an older system but it's something that I can let the kids play on and not be concerned with losing any of my files.
I appreciate any help
iBook 366 Graphite

Duane, Thanks for your reply. Is there any way to test this? I am going to try to see if any of the utility disks can recognize the hd. I've tried DW 4.0, the Utility Disks on OS 9, X. I've even tried FWB and a few other tools.

Hard drives not being recognized on Server 2012 R2

Hi,
I added 2 hard drives to my server but they are not being recognized by the operating system. They show in the bios but no where in the OS do they show. They used to be external hard drives but I took the hard drive out and installed them into the server.
Are there some type of drivers I need to download for them to be recognized? One of them will be shown but it tells me I need to reformat it. I don't want to do this since I have about 1TB of data on it.
Thank you,
James

What server hardware is being used? May need the manufacturer chipset and support pack in the case of integrated disk controller.

External LaCie HD not being recognized after 10.5.6 upgrade?

My LaCie HD used for Super Duper backup is not being recognized by OSX. I also use a WD HD for Time Machine backup.
Before I upgraded to 10.5.6 i repaired permissions and backedup to the LaCie. Now when I turn on the drive, OSX does not see the drive.
I now see an icon in Super Duper in both the Source and Target areas called disk image. I have never seen this before. I do not see anything on my imac HD called disk image.
Any ideas?

Just to let everybody know that P-RAM reset resolved this problem.

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.

'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.

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

WD Passport External Hard Drive Not Being Recognized on PowerBook G4

I bought a WD Passport 320GB USB 2.0 powered external hard drive that isnt recognized by my PowerBook G4. The funny thing is that the external HDD works perfectly on my friends MacBook! What's the deal with that?
I called AppleCare but they just told me to take it into my nearest Apple Store... LAME!
Can anyone else help?

I had the same problem. See below for the answer from WD (...sigh...):
Cause:
Many 15" and 17" Macintosh PowerBook and Mac Book Pro Laptops do not provide enough power through a single USB port for the WD Passport™ external USB hard drive to work correctly. The WD Passport™ external USB hard drive requires a minimum of 1000Ma (Milliamps) of power for proper usage.
Resolution:
You can purchase a WD Passport™ Power Supply or a USB 2.0 Power Booster Cable from links below to the Western Digital Online Store.

IPod Touch 1g not being recognized after installing iTunes.

Win 7 Ultimate
itunes 9.0.2 64 bit
With iTunes or any Apple software uninstalled the iPod is recognized in device manager under portable devices> Apple iPod. I can browse to it within Win Explorer. All looks normal.
Once I install iTunes and I plug in the iPod a popup informs me that it's imstalling Apple Mobile Device USB driver (and is ready to use). Then iTunes starts up and another popup informs me that device driver was not successfully installed. This time MTP USB Device. It then switches to device unplugged, without touching it. Itunes then reports an error (iTunes could not connect to this iPhone because an unknown error occurred (0xE8000065). Device manger then reports a warning for Portable devices > MTP USB Devices. The device status reports This device cannot start (Code 10) (Apple iPod went away)
I have tried uninstalling several times. Different iPods. iPod and cable work just fine on another laptop. Updated MB BIOS.
I need some more clues on what might be wrong. Anybody!!

Hi, jodie_0182.
I would recommend the steps in the article below. See the section labeled Verify that the Apple Mobile Device USB Driver is installed > For Windows Vista, Windows 7, and Windows 8 > Update the Apple Mobile Device Driver.

External Hard Drive not being recognized

I made a topic some time ago but it never got answered.
http://discussions.apple.com/thread.jspa?threadID=1906969&tstart=0&messageID=906 6822#9066822
This hard drive has never worked on this computer and I am still not sure why. It does not show up in Disk Utility or in the System Profiler. It is formatted in FAT32. It is plugged into the wall and comes right up in Windows. As a test I used bootcamp and went into Windows XP. Plugged it into the same USB slot on the side and it came up. But upon rebooting into OS X it was no longer recognized. I actually got it to come up one time by opening USB Probe. After unplugging it and plugging back in, it no longer worked. I don't know what I did that one time but it will not come back. The time I had it running I moved files around to make sure it was working and it seemed fine. Does anyone know what I could do to get it working?

Thank you very much.

OK. They're supposed to be Mac compatible.
I guess you could see if it at least is recognized by the operating system even if it doesn't mount. You can open System Profiler in Utilities (or About this Mac > More Info...). The USB device tree should be under Hardware > USB.

Upgraded hard drive not being recognized

I've upgraded the hard drive in my new Unibody 15" macbook pro to a 7200 rpm Hitatchi Travelstar 7k320 from the original 5400 rpm drive. When I boot from the installer CD, one of the following occurs:
•I am able to open disk utility, see the drive, and reformat/re-partition it. However, the installer fails to copy files to the drive and stops after about 1%.
•Disk Utility fails to erase/re-partition the drive, and the installer unmounts the disk
•Disk Utility does not list the drive as an option at all.
Does anyone have a possible solution? Applecare wouldn't help me out being that the drive is third-party.

Prep the new drive as follows:
Extended Hard Drive Preparation
1. Boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (for Intel Macs) or APM (for PPC Macs) then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.

All external hard drives not being seen after working for months

I have a 27" iMac, 10.7.2.
This morning I had 4 external hard drives attached via a powered hub, 2 x 2TB and 2 x1TB (all Freecom) formatted as MAC OS extended Journaled, one acting as the time machine backup.
All were working and being recognised/seen on the desktop and finder and working normally. I shut down the system and moved the machine to a new office made all the same connections, but now none of the drives are available, they are not even visible on the desktop.
I have tried them directly connected to the usb ports with no luck, I have tried rebooting in safe mode and reset both SMC and PRAM (after looking at various threads)
I have also tried a USB stick which also does not appear on the desktop (or anywhere else), all other peripherals work with the USB ports.
This is a real problem as there is almost 4 terabytes of material and four years work!, any suggestions would be greatfully received.

You mentioned you did a SMC reset, because different models of Mac's have different procedures for doing a SMC reset you may have done it incorrectly meaning you didn't do one at all! Did you do it like this?
SMC RESET
Shut down the computer.
Unplug the computer's power cord and all peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.

External USB hard drive not being recognized

Hello! I'm sure this has been posted before, but excuse my naivety with this sort of thing...
I have a mac mini 10.5.6 (1.83 GHz Intel Core 2 Duo) and I run the Time Machine function to an external usb hard drive. The hard drive worked fine (plugged into the usb port on an older keyboard), but I went out and bought a new aluminum apple keyboard (because they look so cool ^_^ ) - I plugged the external usb drive into the keyboard and it wasn't recognized, so I tried plugging the external drive directly into the mac mini, but it is still not recognized. It is not showing up in Disk Utility or in System Profiler
Help? I'd hate to have to give up this fancy keyboard...
Thank you!
Dr. E

I believe I had my external drive plugged into the (old) keyboard because with the old mac that I had didn't have a free usb port for it - so when I got the mini I just plugged things back in where they were. But I have always had the Time Machine back up to this drive (connected to the keyboard) though it has been slow (another reason I thought the new keyboard was a good idea).
I tried restarting the computer without the alu keyboard plugged in, but same problem of no drive showing up.
Here is what System Profiler has to say about my drive:

I don't know the brand or model as it has 'always' been in the case that in which it currently resides and I didn't physically buy the thing :\ I do know that no software was installed with the drive as I assumed that when I put all the old info from the original mac to the mini that it was the sort of thing that would carry over.
Sorry I'm not terribly helpful - Thank you!

Optical Drive not being recognized by Macbook

I tried inserting a dvd into my Macbook today and it makes a clicking noise (something it used to do when it still played dvd videos), then it spits the dvd or music cd out. For a time it was not recognized in my system profiler, but I just checked it again and it was there, however, it still spits out the cd/dvd I stick in.
Also, when I try to open DVD Player it says, "There was an initialization error. A valid DVD drive could not be found. [-70012]"
Any ideas? I'm up-to-date on my OS and drivers, to my knowledge.

Try the ideas from here.

External Hard Drive Not Being Recognized By MacBook

My Toshiba external hard drive (1TB, brand new) does not show up anywhere on my MacBook Pro (Also brand new). The light on the external hard drive comes on so it's not a connection issue, like the cord being broken. But nothing happens when I plug it into my MacBook, aside from the light coming on. It doesn't pop up on the desktop or in disk utilities or finder. I don't have my old PC laptop any more, all my files from that computer are on this hard drive and all I want to do is transfer them to my MacBook. And even though I don't want to lose any of my files, I can't even erase anything on the external hard drive to reformat it because it's like...not talking to the MacBook...

Your Mac should be able to recognize many different types of drives (including Windows-formatted drives) immediately for Reading, provided they are in good working condition and not damaged. There should be no need to transfer to a different type of drive.
If there is no recognition of this drive, see if it can be seen in Disk Utility.
If your aim is to transfer the data on it DO NOT use ERASE or PARTITION as these will completely erase all the information on the Drive.
If the drive is present while the Mac sleeps, it is likely to drop out and not be seen any longer, especially if it is a USB-powered drive.
