MY HARD DRIVES WONT MOUNT, HELP

I recently bought the Lacie 250 gig fire 400 (I also have a 160 gig porche hard drive) and it worked for awhile. But a few weeks ago when I turned my computer on the hard drive would not mount. I took my computer to the mac store and the tech tested my fire wire and they were just fine. Then he hooked up a hard drive from the store and they mounted just fine. Now heres the weird part. When I brought my computer home both my hard drives mounted just fine. But here we are a few weeks later and now they will not mount again. I have tried everything possible to mount these drives from changing firewire cords to unplugging everything and still nothing. Now the tech said that he thinks that the computer cant tell the difference between the two drives and thats why they wont mount. I need help bad!!!!!!!!
G4 Mac OS X (10.4.7)

If you have the drive backed up, you could
try this. With it plugged in and on go into
disc utility. Check to see if the parent
drive is visible. The drive that is not
mounting is considered a volume mount point.
This is the named volume that you gave it.
The parent drive will have the name the
factory gave it.
Select the parent disc
and try repairing or verifying the disc
to see if it helps. As a last resort you
can erase the disc using no security and
this will usually get the volume to mount.
I would install a OS on it so that it is
more likely to mount.
It will appear that your volume is empty
when actually you data is there but the
directories have been removed.You could
get your data back with a file
recovery program.
I would try the OSX
forum, they will know a few tricks you
might try. Only do the erase as a last
resort.

Hard Drives Not Mounting - Help!

Hello,
This is my first post, so please forgive me if I leave anything out....
I recently had to replace my hard drive. Got it all going, then I noticed when I went to put a music CD in, that it would not show up. I tried others with no luck....then I put in a cd with data, and it showed up on the desktop....
While trying to mess around, I made my 2 LaCie external hard drives go away! I have tried checking cables, and they come on when the computer does, they don't show up in system profiler....
Please let me know what information you might need to help me diagnose these problems....my computer has been so good to me, I want it back up and running...

Hi, mcholley, and welcome to Apple Discussions.
I can't suggest any remedy for your optical drive not reading audio CDs but having no trouble with data CDs, except to say it's apparently a software problem, not hardware-based.
After replacing your hard drive, did you reinstall your operating system from scratch on it, or did you restore your OS from a backup you had made?
The disappearance of your external drives (are they USB or FireWire?) may be power-related. Are they externally powered, or are you powering them from the USB or FireWire bus? If they're bus-powered, are you connecting both of them at once? That won't work: together they demand more power from the bus than it can supply, and while they may spin, they won't mount. Connect only one of them at a time. Is either of them detected by Apple System Profiler when just one is connected to the Powerbook? Does it mount on the desktop then?
If you've been able to connect both drives to the Powerbook at the same time in the past, and both have mounted OK, then there's been some hardware change recently, other than your hard drive replacement, that has caused the loss of external drive detection. Is it possible that during your recent operations you've turned off one or both of the external drives, or disconnected it/them from the Powerbook, without dismounting it from the desktop first? Depending on what, if anything, the drive was doing at the time, that can make a FireWire drive unmountable and all the data on it inaccessible. In that case it may be necessary to erase and reformat the drive. I don't know whether the same is true of USB drives.
Do you have another Mac to which you can connect the drives, to see whether they show up on it? If they do, you might have to consider the possibility that the port(s) to which you've been connecting them on your Powerbook is bad.

External hard drives wont mount

I ejected my two external hard drives before disconnecting them. I have reconnected but they do not show up in the Finder or Disk Utility. The drives show up when plugged into my macbook. jp

Hello, are the USB? Do other USB things work in those ports?
Might try this...
reset FW bus, same goes for USB reset...
Reset the Firewire bus
If your Firewire or USB isn't recognizing any device. A solution which has worked for some whose hard drive became invisible in 10.4 was simply to follow these four steps to reset the Firewire/USB bus:
1. Shut the machine down.
2. UNPLUG the power lead to the computer and any firewire/USB drive.
3. leave it for 10 minutes.
4. Connect back up and reboot.

Usb hard drive wont mount

i have a drive i use on my old computer but my new mac book pro wont even recognize it. anyone have any fixes for this.

I hope that you can help me as well. I just spent 2 hours with Apple tech support to no avail (case # 83844913). I have a Thecus Y.E.S nano N1050 OTG/USB photo bank enclosure on a 40GB drive that I took out of my powerbook when I put in a bigger drive. It mounts fine on my powerbook and it mounts on my macbook pro when in Windows XP but nothing happens in mac mode on my MBP. I've tried providing it with external power, doing that battery removal reset thing, running disk utilities repair, checking for the drive while booting from the install CD. It's weird that it mounts in Bootcamp (which I've uninstalled now) and I previously formatted it in bootcamp as fat32. On my powerbook titanium (which I just wiped and re-installed the newest OS) it mounts fine so I formatted it as MS-dos and it still mounts fine there and backs-up photos fine from cameras but won't mount on my MBP. In the sys profiler it says USB 2.0 Storage Device, so it does show up there. I have apple care but they haven't been able to help!

MacBook Pro 17"... JUST REPAIRED VIA APPLE STORE ...CD/DVD Drive wont mount disks

Macbook Pro (17") wouldn't boot to desktop/homescreen, so I went to Apple.
They sent me to Micro Center for data recovery. Success.
After that, back to Apple then they sent me to Best Buy for new Hard Drive. Success.
Back to Apple. Everything working ok except that my Adobe Creative Suite programs no longer work.
So I try to reinstall via data CD, as I did when I originally installed the programs, but now my CD/DVD drive wont mount ANY disks!
It accepts them, makes some odd noises, then spits back out. Please help!

I'm confused, why did Apple 'send' you to 2 non Apple places for repairs? Did you buy the product from Best Buy? It doesn't seem like Apple made any repairs, so you'll have to get either Micro Center or Best Buy to repair the issue for you.
How long ago were these repairs?

My external hard drive wont show up in the "Save to:" menu when I try to import videos

My old external broke so I found my old one and plugged it in and went to import some videos on imove from an sd card but my external hard drive wont show up on the "save to:" drop down menu. I've been on utility disk to try and repair disk permission but I can't because the button isn't lit up. I can only click on verify disk or repair disk. I tried both of these but it still wont come on the drop down menu. It is showing up on the left in the event library but it has a little yellow triangle with a black exclamation mark in it.
Hope that all makes sense!
Any help would be very much appreciated!

Ok in disk utility it says Format : MS-DOS (FAT32)
Sorry Im not sure what you mean by can it connect via firewire? Sorry I'm a bit useless with technology haha

Tiger randomly stopped allowing my External Hard drive to mount and...

Hello, I have been using an External Hard Drive (1 terabyte Seagate, new) for a couple months if not a year by now for saving movies, and all of my iTunes on it. Its been working wonderfully. However it recently stopped being able to mount citing invalid hard drive and gives me the options of either eject, ignore, or initialize. Im not sure what to do. And also my computer has been acting funny every since the day it started. I will walk you through it step by step.
July 6th I was surfing the web and unfortunetly clicked on a link that aparently contained a trojan. Or atleast thats what my Antivirus notified me of. I had downloaded the trojan some how without a pop up or anything telling me I was downloading anything. (using safari) So i ran a virus scan and saw one virus was in my system and that it couldnt be deleted or repaired by my antivirus program, Im working on getting rid of that but at the time I had my Seagate 1 terabyte external hard drive attached via fire wire to my Macbook. It was working then.
Later that day I unplugged my hard drive and took my laptop around a little bit, nothing unusual. Then when i came back later that night I tried plugging in my hard drive and a pop up stated that the hard drive was unable to mount and I could either eject, ignore, or initilize. I tried may different routes, restarting, letting it all rest, etc. And in Disk Utility i try to verify the disc and it says its unable to and needs repairs. So I try repairing the disc and it says unable to due to an error.
Then yesterday I went to my applications and noticed none of my applications are there anymore. These applications were saved on the internal hard drive so it was very odd to me. However i can still use spotlight to find and open my apps.
My question is, What can I do to allow my external hard drive to mount? I dont figure it is the trojan on my system but could it be? If so how would I fix it? Im mostly worried about getting the data off the external hard drive then I can reformat it. Or if theres a way to just get it back to normal without reformatting Id love to hear it. As for the applications missing and the trojan on my internal hard drive I can fix that, at the very least Ill just reboot my system with my original OS Disc and just start fresh, its about time anyways.
But please. If anyone has ever had their external hard drive just stop mounting and figured out what to do I would be ever so grateful to hear how you did so. The hard drive itself isnt damaged, its not making any unusual sounds. Whenever i plug it into the computer it acts like normal (turning on and what not) until the computer tells me it cannot mount then nothing happens. Ive looked online and it seems to be a software issue.
If its any help I was downloading a torrent (.avi, no viruses) at the time. I know sometimes if one file on the hard drive becomes corrupt the whole thing becomes unusable. Regardless I would appreciate it if anyone knows a way to at the very least retreive the files on the drive, but preferably know how to just get it back to normal. If i could get it to force mount (via terminal or something) I know which file would possibly be the corrupt one or something so I could work with it.

Bejan:
Thanks for posting back with the pics of the messages from your computer. Disk Utility reports "Underlying task reported failure" when repairing a volume is a directory error which cannot be repaired by Disk Utility. Unfortunately, Disk Warrior may not be able to replace the rebuilt directory, either. Tech Tool Pro has a better chance of repairing it, although this particular directory issue can be stubborn, and is often rooted in a hardware issue. Your surest bet is to backup/clone the information on the HDD using a utility like SuperDuper or Carbon Copy Cloner, completely reformat and erase the HDD (directions below), then restore data from backup.
Formatting, Partitioning Erasing an External HDD
• Connect external HDD to computer
• Turn on external HDD
• Start up computer and log in
• Go to Applications > Utilities > Disk Utility and launch DU.
• Select your HDD (manufacturer ID) in left side bar.
• Select Partition tab in main panel.
• Click on Options button
• Select Apple Partition Map (PPC Macs) or GUID Partition Table (Intel Macs)
• Click OK
• Select number of partitions in pull-down menu above Volume diagram.
For more partitions than one, after you have selected the number of partitions adjust the size of the partition by selecting the top partition and typing in the size; then move down if more adjustments need to be made.
(See Dr. Smoke’s FAQ Backup and Recovery for tips on partitioning external HDD)
• Type in name in Name field (usually Macintosh HD)
• Select Volume Format as Mac OS Extended (Journaled)
• Click Partition button at bottom of panel.
• Select Erase tab
• Select the sub-volume (indented) under Manufacturer ID
• Check to be sure your Volume Name and Volume Format are correct.
• Click Erase button
• Repeat above procedure to erase each partition
• Quit Disk Utility.

External Hard drive wont show up in Finder

Hi,
After Mountain Update, the external hard drive icon wont show up in Finder sidebar, Desktop and in Disk Utility.
Is there anything which needs to be set in System Preference ??
I have the External Hard Disk checkbox checked in Finder Preference, inspite of this I cannot see the Hard drive icon
Please help.

You can try looking in Finder Prefereneces.
Go to the Finder Menu > Prefeences
Look at the sidebar pane. Make sure the Devices box is checked.
Go back to your finder window and make sure that Devices are not hidden. To the right of the Devices work there is a dimly visible show/hide command that is visible only when you have your cursor next to the Devices word.
You can also try unpluggin the drive and unplugging its USB cord then plugging it all back in to try again.

Big problems after hard drive failure - Please help.

About 2 weeks ago, my Macbook seized, and was sent to Apple to repair.
It was found that the hard drive failed, and 2 weeks later I received my macbook back with a new hard drive.
Luckily I had backed up my home drive and was able to restore it using backup.
Now this is where my problems start.
My home drive is not the same name ( I think - I can'r remember too well what it was called previously )
I have my entire music library backed up to an external hard drive, and mounting this hard drive is a REAL pain in the *** now.
Sometime it loads up, sometime it just doesn;t get recognised, and I can put the USB connection in and out 10 times before it mounts.
I have verified the disk, and nothing is wrong.
Does anyone know what this problen could be ?
I have left the external hard drive in during the night, and after the macbook goes to sleep, I will go back to it in the morning, and the hard drive has been unmounted, and I repeat the exercise over again of trying to mount the drive.
Its so annoying, and I just dont know wht to do.
If anyone can help, I;d really appreciate it.
Griff

SMART status is a pretty reliable indicator of what is going on. You should back up your irreplaceable files as soon as possible.

I cannot get my hard drive to mount on desktop

Today I had to erase my internal (start-up) hard drive and reinstall Mountain Line (ML) and although the reinstall seems to have occurred correctly - the iMac will now start up and run properly - the icon for the internal hard drive does not appear on the desktop along with the other disk icons. When I hold the option key down during start-up the Hard Drive icon shows up among the other drives attached to my Mac - but the icon or image of the internal hard drive does not appear on the desktop. I tried to use Disk Utility to mount the disk, but even though the disk is listed and shown in the left most column of the Disk Utility window - the drive will not mount on the desktop
I seem to remember that the same thing happened when I originally installed Mountain Line on this machine - and after poking around in countless menus I found an option that when selected caused the internal hard drive to mount on the desktop just fine. But I've not been able to find that option thus far with the newest version of ML. And a search of the "Help" system was useless.
Can anyone shed some light on the resolution of this problem?
Thanks

Finder - Preferences - General - click the boxes you want for "Show these items on the Desktop"

External Hard Drives not Mounting after Yosemite Upgrade

I've just upgraded to Yosemite, and none of my external (USB) hard drives are mounting (they don't even appear in Disk Utility).
Any ideas?

MacBook Pro 2009. 250 SD, HD 8Gb Ram.
I have had this issue for about a year...with no resolve!
Apple and the User community have not been able to solve issue.
I have had to work around it since the Oct 2013 Mavericks upgrade which “killed” (rendered unmountable) both my USB and Optical drives.
Hundreds of replies and remedies have not corrected my issue. Hundreds of replies stating that if there was a global issue it would of been fixed by Apple, not true. And dismissive replies stating that there must be a hardware issue are very discouraging.
So now, hoping to help the voiceless masses, I'm forced to share my experience.
As I stated, I have been having the issue since one of the Mavericks upgrades. The upgrade rendered externally attached drives unmountable...They are all seen in Disk Utility. They are just not mountable. Regardless of the flavor of the disk format, either Mac or PC, they are found, seen and refuse to mount. I can see them using Terminal commands, I can see them in System Report. I can reset all the memory I want...turn it off, reset, sleep, turn on, restart...NOPE...And the optical drive takes in disks but ejects them after an attempted mounting. Keep in mind, there are no physical issues with either USB or optical drives.
So now...I have had enough and need to correct the issue or buy a new equipment - starting to get into software development and need working equipment!!!
For the past month, I have been visiting the Apple store to assist in my issues...Back Story: I'm an IT Field Tech for the largest department store in the country and I have the good fortune of dropping in the Apple store anytime I want...The Geniuses booted the MB with a bootable image of Mavericks, and the USB and Optical drives WORKED fine...So, after I had stumped the Geniuses with my problems, we agreed that we would attempt to format and re-image the MacBook...Fine, do it, it's backed-up, how you ask? - Via my wireless My Book Live 3T drive, which only took 24 hours to backup, AKA Time Machine!
Great news! The re-image of Mavericks proved to work! I WAS able to mount external drives attached! How is that possible? Don't know, don't care! It just worked! So happy!
But wait! I then took the laptop home. Connected to my WiFi, to update Mavericks to the latest version...Good so far! Then it came time for a Time Machine restore, AKA Migration Assistance restore...So, I proceeded to migrate data back to my MB via wireless drive, good so far, booted in Migration Assistant, and I chose to restore everything except the network files, thinking that may be an issue...22 Hours later, the MB migrated without issue...all apps and personal files had migrated! YAY!
BUT NOW THE USB AND OPTICAL DRIVES FAILED TO MOUNT!!!
Great now what? I know, I will just re-image and start again...WAIT, I don't have a Mavericks Install Disk, no problem, I will just create a bootable USB drive with the Mavericks Install Image I downloaded onto my MB this month...NO YOU CANNOT, because you have no use of the USB drives!...And, Apple stopped making OS CDs back in 2009...Oh, and that wouldn't of done me any good, because the optical dive was unusable, anyway!
SO, back to the Apple store with my head hanging! At this point, Yosemite came out the previous Thursday, so no more Mavericks images, great! Perhaps the new OS will alleviate my nightmare!!!!...So, they re-imaged my Mac with Mavericks, drives worked again! SO, I took my MB home and attempted to download the new OS, Yosemite...which only took 2 days due to the amount of traffic on Apple's servers!...Anyway, Yosemite finally installed without out issue! Drives still worked! And so, I shutdown and restarted the system...No issues, USB and optical drives worked beautifully! Yay, Yosemite!...Fixed all my troubles!!!...Not so fast...
And so, I, again, attempted to do a Time Machine restore, via WiFi, this time it took 24 hours to restore...AND it worked! All apps and personal files transferred without issue, So happy! Put the laptop in Sleep and left it home and went to work! Came back from work, tested the system without issues. Rebooted...USB and Optical drive are NOT MOUNTABLE!
So now, what is the file that the restore keeps pushing to my MB that kills the USB and optical drives?
I would just stop restoring from a Time Machine backup, but the only way to get into the TM image is to use Migration Assistant. I cannot view the date in time of the image in TM's Star Wars time line. So, I'm forced to back up everything from the image in Migration Assistance. Not sure that it being an encrypted image has anything to do with it...
...Regardless, what is being “restored” to the MB that continues to configure the OS in such a way that makes all external drives unmountable...keep in mind, my external keyboard, hub and mouse are usable via USB.

My internal hard drive isn't being recognized on my macbook pro but when I put the HD in my Mac Pro (desktop), the desktop computer recognizes the HD. When I insert the installer CD on my laptop, it also doesn't recognize my hard drive. Please help!

I've also been getting an image with the folder and question mark. I've tried everything on the apple support page but it doesn't seem to work either.

Well, I tried all of your suggestions and they didn't work -- no surprise because I was trying to backup to my external c.d. disk. Duh! The application for the home is in the mail.

Hi Everyone. I have an old Mac Book. I have saved a ton of emails in my inbox 'On My Mac'. There are so many it is slowing down my computer. Where do I find the folder with all the emails so I can cut and paste them to an external hard drive?Pls.help.

Hi Everyone. I have an old Mac Book with software updated to 10.6.8. I have saved a ton of emails in my inbox 'On My Mac'. There are so many it is slowing down my computer. Where do I find the folder with all the emails so I can cut and paste them to an external hard drive? Pls.help. Tks.

Depending on which email client software you use
the files should be in 'your home folder' library, esp.
if you use Mail application.... ~/Library/Mail
Since you don't specify what mail application,
that would most be associated with the file.
I notice there are some items to the right of your post
where it says "more like this' so that may be worth a
look to see if similar issues were answered. Also, the
Help viewer in your system is a searchable database.
Seems that google also brings up fair information, too.
Do you have a complete bootable clone of your entire
Mac system on an externally enclosed hard disk drive?
Good luck & happy computing!

My PC computer was wiped (virus) including itunes. How do I transfer the many playlists and music to the new re-installed itunes?? Ipod is synced to old itunes. I have all original music files on external hard drive. Please help?

My PC computer was wiped (virus) including itunes. How do I transfer the many playlists and music on my ipod to the new re-installed itunes?? Ipod is synced to old itunes. I have all original music files on external hard drive. Please help?
New itunes is trying to wipe the ipod. But have many many playlists (many hours making) which I want to save. Any help would be appreciated.

If you want to just extract the playlists from your iPod, plug it in iTunes. When it appears under devices, right->click on it and choose Export Playlists. Save them to a location such as your desktop and them import them into your library once you have copied and imported all of your music back into it.
See this older post from another forum member Zevoneer covering the different methods and software available to assist you with the task of copying content from your iPod back to your PC and into iTunes.

MacBook Pro 2010: Flashing folder w/? on not responding to startup keys & I'm trying to install a new hard drive, can anyone help?

MacBook Pro 2010: Flashing folder w/? on not responding to startup keys & I'm trying to install a new hard drive, can anyone help?

Thanks. It started up com that disk but when I went to install it had an error message (didn't get to write out what it said). So I attempted to restore from time machine but it said there was no space, even though it's a new (replacement under warranty) HGST 1TB HD, so I did what I think was right and tried to partition the disk but it now says 'Partition faild...POSIX report...cannot allocate memory'. im not sure what to do, and I'm trying to remember how the previous hd was installed and formatted for use but that was over a year ago now. Should have erased the hd first or something?
