Flashing question mark folder after RAM upgrade

I took apart my Mac Mini this evening to upgrade the RAM. Thought I did everything right. When I hooked it back up to test it (without completely reinstalling the case), I got the ominous Flashing folder With a Question Mark icon. I did some research and found that this meant that the Mini couldn't find the startup disk. I checked the RAM, reseated it several times, I even put the original Apple RAM back in, nothing changed. I bought a 3 GB upgrade kit (a 1 GB module and a 2 GB module) from OWC, if that matters. Looks like Techworks branded RAM. Though, if the machine won't boot with the original RAM, either... I'm starting to get worried. I have tried resetting PRAM, also. Many times. Of the four USB ports on the back, does it matter which ones my keyboard and mouse are plugged into? I'm not using Apple keyboard/mouse, if that matters. But the keyboard and mouse work just fine. I've also tried inserting a DVD-ROM, to try and boot from that. The computer won't accept it. It's like there's no power to the optical drive. The Mini doesn't emit any chimes or other sounds, either. Any help would be appreciated.

If you followed proper precautions about static electricity when handling the internal parts of the Mini, then the flashing question mark (and the problem with the optical drive) suggests that the sub-assemblies weren't put back together quite right.
Check that no pins are bent and that everything mates properly.
Assuming you have access to another working computer, recheck the videos on the OWC site and make sure you dotted all your i's and crossed all your t's.
I doubt the problem is with the RAM; you probably wouldn't have gotten as far as the "?" if the RAM were totally borked.
If I recall correctly, we had a poster here about two months ago who didn't get the sub-assemblies mated back together quite right. When he solved the mating issue, he was able to boot properly.
(Obviously the solution could be different if you were already having problems with your Mini before the RAM update.)

Flashing question mark folder after update!!!

Yesterday i did an update on my macbook. After the update the system normally starts again, but mine didn't i waited for 20 min and came to the conclusion that i have to hold down the power button. after that i started again and i got a flashing question mark folder. So i took my SSD out ( vertex limited edition) and put my old HDD with snow leopard in to see if i connect the SSD externally if it would show up but it doesn't i took another HDD case but this also didn't work. So i also tried putting my ssd in the macbook of my sister but this also didn't work. I am clueless, i don't know what to do. I still have warranty but i have new data since my last back up and i really would like it back.

I've not seen any other posts about it causing problems, worked fine here. You've tried resetting the PRAM the only other thing you could try is:
Boot holding down Apple/S and don't let go until you see scrolling text.
When that stops and you see a root#: prompt enter
fsck -fy
Let it run through all the checks and repairs.
If it fails first time, at any time, or finds and fixes a fault - run the command again and keep doing so (some fixes can take several passes) until it says "Appears to be OK" then enter
reboot

Flashing Question Mark Folder--after repair of "Office Database damage"

I received a dialogue box message reporting "Office Database Damage--would you like to repair?"
I said "yes" --BIG MISTAKE.
The machine froze and now on boot-up will only give the dreaded Flashing Question Mark Folder".
Booting from the Installation CD is possible, however, when running the Disk Utility, no Mac HD appears in the window of drives you may check. Also, if I proceed to try to do a Clean Installation, there is nothing in the window offering any possible Destinations for Installation ...NOTHING.
When holding the "D" key down and booting from the Install Disk, I am able to run the Hardware Test which shows NO PROBLEM.
Also, if I try to access the computer as a FireWire harddrive from another MacPB connected via firewire, the only thing that shows up is the Install Disk. No HD shows up.
So, it seems I have a software problem, but no way to access the HD to do clean install or run any repair of disk permissions, etc.
ANY IDEAS?????
MacBook Pro 17, 2GB RAM

A friend of mine is having the same problem. This is why I am searching the boards now.
Anyone have an answer?

Flashing Question Mark Folder after Clean Install in Target Disk Mode

I have an old iBook G4 with a failing optical drive and the need to reformat the hard drive and re-install OS 10.5.4. Since the optical drive is failing and unpredictable, I figured I'd do everything in target disk mode.
So I mounted the hard drive of the iBook to my Mac Pro via Firewire in target disk mode. I was able to successfully format the hard drive of the iBook, zeroing out all the data with 7 passes, and I was also able to successfully install OS 10.5.4 from my original Install DVD, again in target disk mode.
After the install was complete, I went through all the registration process and User Account setup and the iBook booted fine albeit still in target disk mode. So I shut down the Mac Pro, turned off the iBook and unplugged the Firewire cable. My Mac Pro booted up just fine afterward. But the iBook now gives me the flashing question mark/finder folder.
I know this means that the iBook is having trouble located a startup volume, or that the startup volume is corrupt or missing data. How can this be, though, after a reformat and clean install? Did I do something wrong in target disk mode? Or did I neglect to do something necessary?
Thanks for anyone's help on this.

Thanks, Niel.
I don't see APM as an option in Disk Utility when booting from my Mac Pro. I only have Mac OS Extended (Journaled), Mac OS Extended, Mac OS Extended (Case-sensitive, Journaled), Mac OS Extended (Case-sensitive), MS-DOS (FAT) and ExFAT.
How do I get my Mac Pro to repartition the iBook properly in target disk mode?

Persistent Flashing Question Mark Folder Icon, after Repair & Rebuild-THX!

Hello All,
Thank you in advance for any insights.
For the past week, one/two days after a force re-boot, my Quicksilver Mac (OSX 10.4.11 and OS 9 Classic) starts up with the dreaded flashing question mark folder.
The start up disk has always been on "Mac OS X, 10.4.11 on main stuff" ("main stuff" is the name of the hard drive.)
The first time, I ran DiskWarrior and rebuilt the hard drive, which is kind of new as it was replaced in April 2009. Then I ran OnyX and got a clean bill of health. The Mac was shut down at the end of the day as is my habit via turning off the power strip.
If it helps, here's part of the DiskWarrior report:
• 13 files had a directory entry with an incorrect text encoding value that was repaired.
• 340 files had a damaged extended attribute that was repaired.
• 3 folders had a directory entry with an incorrect custom icon flag that was repaired.
• Incorrect values in the Volume Information were repaired.
Disk Information:
Files: 370,719
Folders: 85,161
Free Space: 92.55 GB
Format: Mac OS Extended (Journaled)
Block Size: 4 K
Disk Sectors: 268,171,472
Media: WDC WD5000AAKB-00H8A0
The next day, the flashing question mark folder reappeared. This time I used the original system installer CD (labeled Power Mac G4 OS X Install). Disk Utility made its repairs. And this time, the computer was put to sleep instead.
In the morning, it woke up, the wireless optical mouse worked for a few seconds, the hard drive is humming along then all of a sudden the arrow (mouse) froze and none of the keys on the keyboard functioned.
After some research, I deleted the energy saver preference (powermanager.list?) and ran Disk Utility again. And again, I shut down b/c I wasn't going to use the Mac for a day or two.
This afternoon, the pesky icon reappeared at start up. At first Disk Utility didn't see the hard drive then I restarted and the hard drive was selectable though not mounted. It was repaired and verified yet once again. Btw, when I did hard drive test, the message says something to the effect that it appears to be working properly.
My question is, might anyone know what's wrong? I've been backing up after every use and I have a laptop. But I love working on the desktop and if this issue can be fixed, that would be perfect.
As an aside, I've read that I should do a clean install. Would doing a clean install mean I need to re-install OS 9 as well as all other all other software programs-Adobe Creative Suite, Quickbooks, Verizon DSL, printer drivers etc.?
One final question, can I continue to boot up from the CD, repair then restart or will I damage the computer? Once it restart, everything seems to work normally and well.
Many, many thanks for reading and any help would be greatly appreciated!
Have a wonderful weekend.
Sam

Disk damage can also affect the startup sequence, but I think what you have already done should have repaired any disk damage, or given you more information.
Once you have ruled out Disk damage, you get the flashing question mark when your Mac cannot find:
• the preferred operating System
• of the preferred version
• on the preferred startup drive.
All these items are stored in the parameter RAM, backed up by a 3.6 volt, non-recharging 1/2-AA size battery that lasts three years or so, unless you turn off all power at night.
If you cannot remember when you last changed that battery, now is a good time. Be sure to reset the PMU/PRAM after installing the new battery.

Flashing Question Mark Folder... with a twist

Hi all, I hope you can help me out.
A month ago I had some trouble with my MacBook. It would continually freeze, then when I restarted it would show the flashing question mark folder icon. When I booted from the OSX CD it couldn't see any drives to install to. Restting the PRAM eventually fixed the issue, but only temporarily: it kept doing it and eventually it seemed that the hard drive was well and truly dead.
I took it to my Mac shop and they replaced the hard drive for me as it was still under my Applecare warranty. Things seemed fine for a couple of weeks.
Then it happened again. Now it seems to have skipped the stage where resetting the PRAM would fix things and has gone straight to the signs of a dead hard drive. I find it hard to believe the replacement drive has died after a couple of weeks. Is there some other issue, such as a faulty motherboard, which could be killing hard drives?
My MacBook is a Core 2 Duo 2.0, with 2GB of RAM and 200GB hard drive, running the latest version of OSX.

I had this happen to my MB a few weeks after purchasing it last November. I took it to the Genius Bar at my Apple Store, and the Genius took my HD out to test it, and said that it had completely locked up, and he wasn't able to get it to load on at all, and that it was dead. They sent it away for me, I got it back a couple days later with a brand new HD, and I haven't had a problem since.
My lesson learned: Backup, Backup, Backup!!! I use Apple's Backup App because it came w/ my .Mac account, but there's plenty of other great Backup Apps out there. Have one or more External HDs set up as backups in case anything happens to your internal, and remember a computer is a computer and sometimes they have problems. However, it does sound like Apple invested in a bad lot of HDs. If it's happening to a lot of people, report it to Apple. There may need to be a recall.

Flashing Question Mark Folder on Start-up

I recently starting having administration issues with my Mac Mini.
I went to update to OS 10.5.7 and when the administrator box came up asking for my password, my name was missing. After putting in the correct information, was unable to update, but received the message what my clue to password was.
Anyway, I performed a safe startup, changed the password and tried again. Same issue as before. So I started up from the Start Up Disk, and ran Disk Utilities and verified the disk and repaired any permission issues. When I started up my Mac Mini from the hard drive, I still did not have my administrator password working.
At this point, the start-up ping is gone.
I reset the Pram and had the same issue. So, I saved all important files to an external hard drive and tried to do a clean install. I was unable to do the clean install.
I removed the hard drive from my Mac Mini and installed it into a friends Mac Mini. I had complete control of my computer with no administrator password issues, the ping was there, and I could reload all saved items and still not have any issue no matter how I started up the computer. I then performed a complete erase and reinstall and still had no problems.
I reinstalled the hard drive into my Mac Mini, and I now have the Flashing Question Mark Folder with gray screen on start-up and no ping. Can't fire wire to start up, can't clone, can't start-up from disk, safe mode, etc..
Any ideas would be helpful. Most likely I will be going to the Apple Store and seeing what they can do.

generally, the flashing folder mark means it can not find the startup drive.
if you hear those kind of noises your hard drive is most likely dead. while this is almost certainly true you can try booting from the install DVD and see if the drive is visible in disk utility. if you can't insert the DVD try this. reboot and hold option at the chime. this should boot you into startup drive manager. there you should be able to insert the DVd and choose it as the startup drive. boot from the DVd and once past the language screen start disk utility from the Utilities menu at the top. see if it detects the internal drive. if it does, try repairing it. if it doesn't the drive is dead.

Macbook pro flashing question mark folder, won't recognize hard drive

My 2010 macbook pro froze and after restarting I was greeted with a flashing question mark folder. I then restarted again and held down "option" key and went into Mac OS X utilities then into disk utilities. In disk utilities, my only drive options are "superdrive" "disk0" and a subfolder of "disk0" labeled "Mac OS x Base system". My hard drive is no where to be seen. I also tried to install a new hard drive but the same thing happened, the computer could not recognize that there was a hard drive present. What can I do to fix this??

Hi bigdubee,
The exact same thing happened to my 2010 MacBook Pro today. Restarting with the "option" key held down, I get only 2 of the 3 options you listed in disk utilities ("disk0" and a subfolder of "disk0" labeled "Mac OS x Base system".
Did you take your Macbook Pro to the Apple store? And were they able to fix it?

Hard disk in mums macbook failed, bought a new one, formatted it first. Have tried starting it with every possible key and I either get flashing question mark folder or a cursor.

Hard disk in mums macbook failed, bought a new one, used sata adapter cable to format it for mac first. Connected it and have tried starting it with every possible key combination and I either get flashing question mark folder or a cursor. A disk is stuck in it so I can't boot from OSX, and yes I have tried every option of starting to try and eject disk but none work. HELP ME!

Five ways to eject a stuck CD or DVD from the optical drive
Ejecting the stuck disc can usually be done in one of the following ways:
1. Restart the computer and after the chime press and hold down the
      left mouse button until the disc ejects.
2. Press the Eject button on your keyboard.
3. Click on the Eject button in the menubar.
4. Press COMMAND-E.
5. If none of the above work try this: Open the Terminal application in
      your Utilities folder. At the prompt enter or paste the following:
        /usr/bin/drutil eject
If this fails then try this:
Boot the computer into Single-user Mode. At the prompt enter the same command as used above. To restart the computer enter "reboot" at the prompt without quotes.
If you have a 2010 MBP or later, then you can use Internet Recovery. Start by rebooting the computer. At the chime press and hold down the COMMAND-OPTION-R keys until a Globe appears in the upper part of the screen. This process can take upwards of 15 minutes to get connected to the Apple network servers. You should eventually see the utility screen of the Recovery HD. You may now go about the process to install Mountain Lion:
Install Lion/Mountain Lion on a New HDD/SDD
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Internet Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
Partition and Format the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your external hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. 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. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Install button. Be sure to select the correct drive to use if you have more than one.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

Flashing question mark folder at start, broken CD drive, warranty Q's.

Hello! Thanks for reading.
Okay, so here's the background: I was just chilling around the house yesterday with my macbook, and it freezes, with no response from the touchpad or keyboard. I figure no problem, and just turn it off and on again. And then thats when I got the flashing question mark folder.
So I hopped on my family's PC to do some research, hoping to be able to fix it myself. Turns out the best way to fix it is to pop in the disk that came with the computer during start up... which I can't do because my disk drive is broken. I also tried other things, like pressing various keys (ctrl + option + p + r, or something like that)... and that didn't work.
The disk drive broke when I was at school, and as it was finals week, I had no time to get my computer to a genius bar. Then I moved quite a distance (see below), a process which has taken up most of my summer and made me quite busy to the point it has taken my macbook pretty much dying on me to get it to a genius bar. Gah.
So I guess I have a lot of questions now.
My computer is JUST a year old, by give or take a week or two.
I bought my computer from an authorized U.S. reseller in Japan while I was living there (I live in the US now, which I definitely wasn't expecting a year ago)... and no contact from apple came to buy apple care. Is it possible that because of the circumstance under which I bought my computer, that apple may still cover any repair or replacement fees under the warranty?
Also, I made an appointment at the local genius bar. Will that be free?
Also, does anybody have any other suggestions about how to get my computer up and running away from the **** that is the question mark folder?
Much thanks! I appreciate your time.

You made 2 big mistakes. 1) Apple may or may not contact you about AppleCare (sometimes I've gotten a postcard or email and other times I've not) but it is up to you to buy it before the 1 year mark. 2) whether it was convenient to get the computer repaired at the time or not, you should have contacted Apple to get the issue in the computer. If you didn't, Apple has no reason to believe it happened after the warranty ended.
You are going to foot the bill for the repairs

Intermittent Flashing Question Mark Folder

I've got a iBook g4 that seems to be having an intermittent problem booting. A few months back on boot it came up with a flashing question mark folder. After trying a few things it finally booted OK. For months all was good; until yesterday. The same thing happened again. I tried to boot from an install CD to run disk utility, but the drive didn't show up. After a few attempts I was able to successfully boot in target disk mode. After that it booted OK again. I noted in the log a number of I/O errors which makes me think the hard drive is starting to fail. Anyone have any other thoughts or suggestions?

It looks like things are getting worse. I ran diagnostics and everything passed. Is there a reasonable way to make sure the hard disk is the problem? It now will boot only rarely; sometimes hanging on a gray apple screen, sometimes showing disk I/O error messages in the upper left corner of the display, sometimes showing the question mark folder, and occasionally booting. Replacing the hard drive is reasonable, but I'd like to have a measure of confidence that will fix the problem.

GSoD, flashing question mark folder

Okay, after reading here a bit the suggestions aren't fixing my particular issue. We have a black MacBook running 10.3.
On boot, the GSoD comes up, and then the flashing question mark folder.
Tried putting in the Install CD and pressing at various times S, C, Apple, Shift, and Option. The Option gives a cursor but nothing else.
Pulled the DIMMS, cleaned off a white dust, and then installed them one at a time. No luck.
Wife had reported slowness during the evenings but she attributed that to me being on my computer.
Thoughts?
Leam

Hi Leam,
Are you sure it's running OS X 10.3? Reason I ask, is because the MacBook was released with 10.4.6 (May 2006). So if it's running Panther then the unit was downgraded. Matter of fact, I don't even think you can put 10.3 on an Intel Mac. Not to mention, OS X 10.3 doesn't offer Rosetta support so you wouldn't be able to install Intel applications on the machine.
Regarding the flashing question mark/folder icon, that's indicative of a missing, bootable OS. Which can translate into some of the following scenarios:
1.) The OS is corrupted and needs to be repaired or reinstalled
2.) The OS cannot be located because the HD is failing or has failed
3.) The HD's connection to the logic board has been lost or damaged and thus a proper boot sequence cannot be performed.
I'm unsure where you read about the "S" key on startup, the "C" key makes sense to try and boot off the disc drive. I take it that didn't actually occur, though?
I've seen scenarios where a HD can lock up the system bus and cause boot issues, like you're experiencing. Basically it prevents the optical drive from being accessed, despite valid startup keyboard commands. If you can't boot normally or off the installation disc, the next scenario would be the following:
1.) Remove the HD from the unit, mount it into an external enclosure and attempt to boot from a CD and repair the external HD.
2.) Bring the unit into a service provider / retail store for further diagnostics.

There is no installed OS or you have a dead hard drive. Start by booting from the original installer disc that came with the computer or an installer disc that has a later version than the original such as a Snow Leopard DVD. Then you can do this:
Reinstall OS X without erasing the drive
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard 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. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install Mac OS X 10.6.8 Update Combo v1.1.

G4 17' won't boot, flashing question mark folder with complications

I'm editing a final cut pro project, due to air on friday at noon and during conversion in compressor to dvd format, final cut quits then the computer freezes up. On a hard restart I get the flashing question mark folder.... i know what that means
I was able to boot up after a couple of tries from the os 10.4 (tiger) cd and the hard drive shows up but disk utility can't make the repair. This is the error i get:
booted with the tiger os cd and got to the disk utility. the hard drive does show up with some generic-y looking name. I try to repair the disk and get this error (in red):
Invalid node structure
Volume check failed.
Error: The underlying task reported failure on exit
then it says:
1 volume could not be repaired because of an error
g4 powerbook 17" Mac OS X (10.4.9)
so then i get the bright idea that i will change the startup disk to network drive and try to start from another drive on the network. it tries to find it then goes back to the flashing question mark. I've restarted holding the c key down with the tiger cd back in there and it is spinning but it never reads it.
any ideas? I REALLY need to salvage this film if possible.
thanks!!!!!
donna
Has anyone seen this before? What is my next step--short of erasing the drive. i really need to get this project off.
thanks in advance for any and all help!!!!!
g4 powerbook 17" Mac OS X (10.4.9)

i'd try disk warrior except that i cant get it to boot from ANY cd right now EXCEPT apple hardware test. and i have NO idea what to do with that.
I've tried booting in option mode and all i get is the little restart button and the forward arrow button but NO drive options
it won't pick up my other laptop in target mode
i've even put in Norton Utilites 8.x and it won't boot up from that either.
i've zapped the pram--nothing
know of any other boot tricks or shortcuts?
