Internal hard drive not reconized, internal hard drive not reconized

one day on my computer screen a folder with a ? showed up and it didn't boot back up. I check the web and it said it had to do with the hard drive so I purchased a new hard drive but that didn't work. I how ever did also purchase a kit to external connect the hard drive thru usb and both old and new hard drive show up. after that I did a little more research and found a few listing saying that the cable goes bad and that might be the problem but I need help or any suggestions thanks

it is your sata cable if your hard drive boots through the external usb enclosure...
go to ifixit.com and order the right cable for your Macbook....it's an easy fix if you're technically capable.

I have a late 2012 iMac running osx 10.8.5. I keep losing access to my internal hard drive. I can reboot and regain access and it will last for a few minutes or hours. Disk utility does not seems to help.

I have a late 2012 iMac with an I5 precessor running OSX 10.8.5 and a 1tb internal hard drive. I keep losing access to the internal hard drive/startup disk.
I can reboot and everything operates as normal for a few minutes or hours but then I lose all access again to anything on the hard drive. The computer is still up and running but no files can be accessed and certain websites cannot be acessed even though internet access appears to be normal. Disk utility can only find permission errors related to iTunes which can be repaired only to come back at the next scan (I would not think permission errors would have anything to do with the hard drive crashing). It does not seem to matter what program I am using at the time access is lost and it can lose access sometimes right after reboot when no program is running.

You will need to boot into the Recovery Volume (command - R on a restart or hold down the option/alt key during restart and select it) to run Disk Utility/Disk Repair.

IMac G5 Internal Hard Drive Not Recognized

I shut down my iMac G5 with the power button and not through the typical shutdown procedure once and then when it booted up it would not get past the gray screen. I eventually used the Leopard DVD to try to boot it and was able to get to disk utility to look at the drive. I tried to repair the drive but then the machine froze and I had to restart once more. Now the internal hard drive isn't recognized or seen at all. I actually switched out the SATA hard drive with another spare I had and that was not recognized either. I can get the mac to recognize the installation DVD still so I know my computer still functions properly but I just need it to recognize the drive now. Does anyone have any ideas how to resolve this?

Have you access to DiskWarrior or TechToolPro? Either of those might fix your problem otherwise, try booting from the Apple Hardware Test on your install disc and see what it says.

When I try to import, I receive the following message: "An internal error has occurred: not enough memory". I always download my photos onto an external hard drive.

Yesterday,I downloaded an update for Lightroom 5. Now when I try to import, I receive the following message: "An internal error has occurred: not enough memory". The message comes up right after I click import, before I choose a file to upload.Here is the information I can think of that might be needed to answer this question:
- I always download my photos onto an external hard drive.It is about 10 % full.
- It says I have Lightroom 5.6 64 bit
- I am working from a newer laptop (Windows). The internal drive on the laptop has 289 gb and I am using 61 gb total memory.
- I have edited 2794 photos in Lightroom and it is all in one catalog.
- I did not have this problem until I made the update. I did have my first "bug" earlier this week when one of my photos had a line show up through the middle of it when I exported it. I was able to export it a second time without the line.
If there is more info. needed, let me know. I do photography as a hobby and know enough about Lightroom to edit out blemishes and adjust color balance, but not too much more, so forgive my ignorance if this is an obvious fix.
Sincerely,
Adrianne

Not Enough Memory typically refers to RAM. How much RAM do you have on your 64-bit OS computer? Do you have other programs running that may be using most of the memory?

I can not store all my Music on my internal Macbook pro hard drive so I am storing it on a large external drive connected to my airport extrem. How do I get Itunes to search for the music here with out trying to copy it to my laptops hard drive??

I can not store all my Music on my internal Macbook pro hard drive so I am storing it on a large external drive connected to my airport extreme (2 TB drive plugged into the USB port). I see the drive on my laptop and I can add and delete files no problem. How do I get Itunes to search for the music here with out trying to copy it to my laptop's hard drive? I don't have enough space to do that.

How did you move the music to the external drive? What exactly is on the drive? The entire iTunes folder or only music? If it is the entire iTunes folder you can do the option+start suggestion earlier. If you copied only music and did so by dragging it there then you need to delete it again and consolidate/organize it there instead so iTunes tracks the move. iTunes 12 for Mac: Change where your iTunes files are stored - http://support.apple.com/kb/PH19507

My internal hard drive is not recognized by the leopard installer disk

i just got my leopard delivered this morning, and have just put it in, every thing is going well, until it comes to the screen where you select the hard drive you want to install leopard on, and my internal hard drive does not show up, however other drives do (like my external hard drives and usb sticks).
really hope someone can help! thanks

I am having the same problem with my MBP with Leopard. I get a flashing question mark on startup, and have repaired/permissions and my startup disk doesn't show up. I reset PRAM, and then ran permissions again to no avail. If it really is Spotlight just indexing, Apple should tell us that in their technical documents. If anyone has any other solutions, that would be appreciated.

I move folders from my internal hard drive twice to an external hard drive. Now I believe Lr does not know how to find my photos. What can I do to get this cleared up.

I move folders from my internal hard drive twice to an external hard drive. Now I believe Lr does not know how to find my photos. What can I do to get this cleared up.

Jim has a very good suggestion. There are many factors at work here:
1) How are you connecting the external drive to the computer?
2) How big are files (329 x 1MB is not the same as 329 x 25MB)?
3) What is your computer specification?
4) Do you have any power saving settings on (in particular something that would send the computer/hard drives to sleep)?

New internal hard drive not recognized at all!

Hello everybody!
I really need your help. I tried to upgrade my internal 120gb drive to a Western Digital wd2500bevs. But when I start my Macbook with the Leopard DVD neither the System Profiler nor the Disk Utilities Program recognize the drive for a possible installation. When I reinstall the old drive everything is back to normal and works perfectly.
This is what I already tried to fix the problem:
I took the drive into an external casing => it was recognized immediately
I then formatted it => no change after installing it into the Macbook again.
I cloned my system with CCC on the WD and then installed it => no system found.
I have another disk of this kind but the same problem and another 160gb Toshiba disk which is not recognized as well.
Please help me! I couldn't find help in German discussions yet so I hope anyone of you guys can help me.

You say the drive is "recognized" but your original post stated it was not present in Disk Utility. I'm puzzled. Have you attempted to partition and format the drive?
Extended Hard Drive Preparation
1. Boot from your OS X Installer Disk. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger.)
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. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the number of partitions from the dropdown menu (use 1 partition unless you wish to make more.) Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the volume(s) mount on the Desktop.
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 will take 30 minutes to an hour or more depending upon the drive size.

Hard drive (internal) not showing up on desktop

One of my internal hard drives is not showing up on the desktop. (Soft freeze after waking from sleep mode. I pushed the reset button on the front of the tower. Haven't seen anything on that hard drive since. I haven't been able to access it since.)
Hard drive shows up in disk utility but I can't mount it. Looks something like this:
74.5 GB WDC WD800JB-00CRA1
There is nothing below that. (Normally indented below is the name ie. Macintosh HD)
I cannot verify or repair disk or disk permissions. I cannot mount it. All these options are grayed out. I took it to the Apple store genius bar. They think the disk is fine but "the partition is lost." (I didn't partition the hard drive. Don't really understand what that means.) I've tried Data Rescue (369 hours remaining) nothing is being recovered.
I've tried Disk Warrior. In the "Hardware" option I can choose the disk and run a test. It says it is fine. ("This hard drive's built-in S.M.A.R.T. diagnostics indicate the drive is functioning normally. Test complete") In the "Directory" option the disk doesn't show up. So I can't rebuild the directory.
What else can I do?
G4 Mac OS X (10.3.9)

The Apple System Profiler shows all the correct info except the name is "unknown." The only 2 places that seem wrong are the desktop - no hard drive, and in Disk Utility. I don't know what it's called, but the line directly under the listed hard drive in Disk Utility (74.5 GB WDC WD800JB-00CRA1) should have the name of the hard drive (Macintosh HD) listed but it does not. It should look like this but with an icon of a hard drive in front of each line:
74.5 GB WDC WD800JB-00CRA1
Macintosh HD
The second line (Macintosh HD) is not there. The other hard drives have their names listed. Apple seems to think this is a problem but other than running Data Rescue and Disk Warrior (neither of which did anything) they have not given me any other suggestions.
The computer knows the hard drive is there but it won't let me access it. I have done, tried, and checked all the easy stuff. (Cables, any and every type of connection, restarting holding down option + apple + F + O and all the other restart variations with and without the OSX CD, and running "rescue" programs.) Nothing has worked. Short of an exorcism, I'm out of ideas.

Internal hard drive not showing up in Finder

Hello. Whenever I use Lightroom and Photoshop, I have been getting the error about my startup disk being low on space. I've read through several threads and instructions on different strategies to take. However, many of them start with being able to click on the internal drive within the Devices section in Finder.
My internal harddrive does not appear in the Devices section in Finder. I have iDisk and then two gray harddrive icons that have the name of my external drive. Even when my external drive is not connected to the machine, I have these two.
When I click on them, it just keeps whatever I had clicked on previously. For example, when I click on "Desktop" it shows my desktop and when I click on the mystery gray drive, it keeps desktop.
I've run disk utility > repair permissions and I get several messages that permissions differ on some things and warnings about SUID files on other things.
Am I in the right spot to fix my problem? What kind of error should I be looking for and when I find that error, what do I do?
My thinking is that once I fix this problem, I can move on to my low disk space problem. Finder shows that I have 8.39GB of free space but that goes down to Zero fairly often.
Thanks in advance for your help.

Internal Hard Drive Not Appearing in Finder

I just had to do a reboot of my Mac Pro as Final Cut Pro kept locking up and when the computer was back up, one of my Western Digital 2 TB internal hard drives is missing! When I restart, I got a message saying something like the disc inserted cannot be used. It had 3 options and the first time I hit eject thinking it was talking about a DVD, then when I rebooted again I hit the details button and it pulled up Disk Utility. I can see my HD in the menu but when I click on it is says unmounted. The other 2 TB WD Hard drive is working fine. Do I need to click on the verify disk or repair disk button? What should I do? I have quite a bit of video footage on this drive that is missing so I'm super worried I will lose the videos!

The drive is a goner otherwise though. Since I was solely using this failed drive recently, I may have just worn it out, which is too bad, even though I worked with an identical 2 TB WD internal drive earlier this year and never had problems with that one.
Drives shouldn't just wear out from use, at least not in a reasonable number of years. They are designed for that. Drives however do fail. However, that drive is more likely to be badly corrupted than it is to be mechanically failing. When you are finished grabbing the data off it, use Disk Utility to zero it out. If it can successfully be zeroed out then it is most likely fine to continue to use.

Power Mac G4 will not Recognize any Internal Hard Drives

My G4 was working fine and I wanted to install a driver for a 'Twin Turbo Mac Video Card' I had in a PCI slot but it required OS9 running. At the time, I had two internal drives 230 and 120 G running 10.4.11 but no OS9. However, I did have an external Firewire Drive with OS9 and OSX. I set my "Startup Disk" preference to boot from FW drive and selected OS9 then shut down my G4. When I powered back on I got the standard "gong" but on my display I saw a "Mac Folder and a Question Mark". I believe that means the system can't find a drive. Is that correct? I reverted back to my original configuration with the internal drives and the FW drive disconnected and I still see the "Folder and Question Mark". I inserted the Tiger DVD, held down the "C" key and it still will not boot from the DVD either. I once again tried connecting a FireWire External drive with OS 10.4.11 installed and the internal drives disconnected and still no bootup. I swapped out Memory, replaced the Motherboard and the battery and even tried resetting the PRAM. Still that stupid Question Mark is showing!! This has really got me puzzled. Any ideas or suggestions out there?

Depressing/holding the Option key at startup activates the Startup Manager (not open firmware). The resulting window shows all of the available startup volumes (hard drives, CD, DVD, etc).

TC not backing up both of my internal hard drives.

So I am having a frustrating issue with my TC setup. I have a mac mini that has two internal hard drives each one being 500 GB. My TC drive is 1 TB. When I go to time machine preferences and click options I do not have any of my internal drives in the exclude lists. In fact it says that the estimated size of full backup is 733.31 GB which seems to imply that TC would be backing up both internal drives to my one external TC drive.
The problem is when I enter time machine and click on my second internal hard drive all the files are greyed out. I can see them all there but can't do anthing with them because they are grey. This is not the case for the main system drive.
I refered to this thread https://discussions.apple.com/thread/2022065?threadID=2022065&tstart=0 and checked in the disk utility to see if all the drives were in the proper format. Indeed all my drives are formatted as Mac OS Extended (Journaled). At this point I have no idea why all the files in my second internal hard drive are greyed out when I enter TC. I would greatly appreciate any help with this issue.

Did you change something in the setup after the TM had been running for a while.. is it running Lion server still?
Look at E2 and E3 in Pondini. http://pondini.org/TM/Troubleshooting.html
Some of these kinds of things are really complex.
Are you running the widget as that might show what is happening. See A1 reference above.
Is enough of the TC hard disk used up to suggest the backups have been working.. ie if the estimated backup size is 733GB is at least that much disk space used. If not it could be that TM has already not got enough space to back up the second drive.. although it should spit out an error message.
I would strongly recommend you buy CCC or some other decent backup software, and create a full clone of the boot drive and full backup of the second drive .. you can plug in a 1TB USB drive.. and save it all. Then if something goes wrong you have the server up and running again immediately. (You may have already done this, in which case please excuse the comments).

"Not enough free space" with multiple internal hard drives

I have a Power Mac G4, dual 1.25 Ghz, 2mb Ram running 10.5.8. I have four 500gb internal drives. I've had a number of issues with my internal drives lately. Hopefully someone here can help.
When I "get info" none of the drives display capacity or availability.
When I attempt to copy files from one drive to another I will consistently receive this error:
"The item "filename" cannot be copied because there is not enough free space.
My startup drive should have over 400GB of freespace, so there is plenty of space. This problem also occurs when I connect my Macbook Pro in target mode and attempt to transfer over files.
I was able to boot the G4 into target mode and backup my data. I then installed a fresh copy of OS X 10.5, then did the 10.5.8 combo update (not through software update).
This seems to have fixed the problem as I was copying and organizing my files back and forth between drives quite easily. However, the problem has returned from out of nowhere.
Anybody have ideas what this could possibly be?

Hi iliveontrantor, and a warm welcome to the forums!
Have you emptied the Trash on those drives?
Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair. Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
How much free space is on the HD, where has all the space gone?
OmniDiskSweeper is likely the easiest/best, and is now free...

Internal hard drives not mounting on startup

Problem: I recently did a clean install of Mac OS X 10.8 Mountain Lion on my Early 2008 Mac Pro. Since then, one or more of my four internal hard drives will not mount at startup, and it's seemingly random which ones will or won't mount; it differs from one startup to the next. Obviously, the boot drive starts up, but the remaining three drives are hit-or-miss.
Troubleshooting So Far: I can open Disk Utility and mount the disk(s) manually, and when I click Verify Disk, the hardware checks out okay. After my most recent startup, I brought up the System Log in Terminal (sudo syslog -B) and found this entry for one disk ("Media 1") that did not mount:
Apr 25 10:40:09 new-host-2.home fseventsd[48] <Critical>: event logs in /Volumes/Media 1/.fseventsd out of sync with volume. destroying old logs. (454 0 68038)

There were no entries for the disks that mounted correctly. Can anyone make sense of this for me? The system jargon is a little beyond me.
Thanks for your help!

Is "Media 1" the name of the volume, or is it just "Media"?
