Error message that "the disk you inserted was not readable by the computer" when I haven't put any disk or drives in. This seems to be impacting Safari as well

Getting "the disk you inserted was not readable" when restarting computer. This seems to be causing problems in Safari taking many minutes to load some pages that in the past took seconds

Start with SMC and PRAM resets:

IMac "The disk you inserted was not readable by your computer"

My 2 year old iMac will no longer read dual layered DVD's. For example I just bought x-plane 10 and everytime I insert the disk a error message come up saying the disk you inserted was not readable by your computer, when the version I got is dual layered as for Mac OS X. Has anyone had the same problem with loading dual layered disks. Movie DVD's do not work and x-plane 10 does not work, but the office 2010 dvd and the MAC OS X dvd works, I don't think these two are dual layered.
Please help Thanks
X-plane 10 is for both mac and pc

PLEASE HELP ME!!

Question about message "The drive you inserted was not readable..."

This might not be a Snow Leopard question, but that's the most recent thing I've changed, so here goes (and my apologies for the length of this): I started with an Intel Mac Mini running OSX 10.5 (with all of the updates) which has a USB-connected HP printer/scanner. This has run well for quite some time. Subsequently, I purchased two Seagate USB external drives (an Expansion Hard Drive and a GoFlex drive). The drives themselves seem to work fine, everything shows up reliably and I've had no obvious problems. However, soon after the drives were connected, I started getting the message "The disk you inserted was not readable by your computer." I determined, by restarting with various components disconnected, that the message appears when I connect the USB cable of my printer to the computer. This did not happen before I purchased the Seagate drives. Thinking that I just had old software, I updated the HP printer drivers and updated to Snow Leopard; however, I still have the same issue. I have to respond to the message by clicking "Ignore". Looking at the console log, I can see that, when I connect the printer USB cable, it shows "com.apple.kextd: /System/Library/Extensions/Seagate Storage Driver.kext does not declare a kernel dependency; using com.apple.kernel.6.0."

How do I view and open all my files again that are on my external hard drive?? Error message saying 'The disk you inserted was not readable by this computer' Three options are Initialize, Ignore or Eject.

I have recently purchased Toshiba 1TB hard drive and I set it up and I was able to transfer all my files onto it such as my music, photos, documents. I had correctly ejected and used it again and all these files were safely stored and accessible afterwards. However after I rebooted my computer as it had been going slow and I had too much clogging it up once I reconnected the external hard drive I have error message saying 'The disk you inserted was not readable by this computer' Three options are Initialize, Ignore or Eject. How do I access all my files? I set it up to work on both mac and windows. I have tried both another mac and windows computer and same issue occurs?? I am worried that all my personal files are gone but am confused as the drive has had absolutely no damage to it as it was in a very short time frame and its never left the same spot. Any help would be greatly appreciated. Thanks

Thanks for your quick response. I had a look at your discussion... I tried it on a Windows machine and I thought that was compatible with ExFAT?
Therefore I need to attempt to use my external hard drive with a machine that boasts OS X 10.6.5 or above and then it should work?
Thanks

My external LaCie drive gets an error message "the disc you inserted was not readable by this computer." The only options offered are "ignore" or "eject" Disk Utility sees the disc but does not give a repair option. What can I do?

The good thing about mac-centric resellers such as OWC, is they have people on staff that can answer questions without you buying things first. They also have how-to information, and instructions are included in many of their products. I saw a link to watch a DIY video in one of their pages; an example of a RAID (with its own power supply) is shown on their drives page. Also a few in there, with no power supplies, for less money.
If I were looking to backup and perhaps also have a partition for a system clone, I'd consider something like one of these: http://eshop.macsales.com/shop/firewire/1394/USB/EliteAL/eSATA_FW800_FW400_USB
Some ideas on the RAID backup methods appear in google search, some of the pages are ideas and concepts; and the better ones also warn about using RAID for the only backup plan.
Oh, OWC has live chat. Haven't tried it, nor have I bought anything from them. I have what appears to be two products from them, but have not used either. One is in a box as-new, but has only USB2.0 ports & my Macs needed FW400/800. It has been said their RAM is a good way to upgrade, too. But I can't confirm!
A 'RAID-ready' unit for backup may be more versatile for just that, but I have not checked into these details. I use single HDDs in powered enclosures, and usually manually make backup clones to FW drives, of bootable OS X systems. Some of the OWC raid-ready use eSATA ports so that may not be viable for a computer without them.
The unused in-box external drive I have is like the base model in the link above. However mine is USB2.0 (maybe) and won't boot my older Macs due to hardware variance; and my preference would be for FireWire options, these models do offer that. But the one I have does not. Dual 500GB HDDs, and they could be used in tandem as a RAID. That would be a choice set up in software. I'm not sure and not interested enough to read up just now.
My backup method is not automatic, or a moving backup plan, if I don't get a move-on and make full system clones. I do make copies of photos and documents the manual way, to USB external drives; and occasionally backup to DVD or CD media. And USB flash, that helps to move files between computers without need to use file sharing via wi-fi. {Like Why fly? Walking is better exercise unless one is a bird. Squawk!}
https://www.google.com/#q=raid+backup+mac
Depending on the ports in your Mac, you may be able to use other cables to attach between a backup or externally enclosed hard disk drive with multiple partition and bootable clone in one of them. Not sure about the Thunderbolt, and where that is the main port, adapters are required to access other devices, as allowed.
Anyway, I am going on and on, yet not really saying anything.
My ideas would not be all that interesting to follow as a backup
plan when matching available newer hardware to task, but you
can get some into better ideas if you are not in a rush. Get a
good setup and then look into more an betterer stuff.
Good luck & happy computing!

I've been getting the error message "The disk you inserted was not readable by the computer". I can't open system preferences, disk utility, or Time Machine. I'm guessing it has something to do with my external hard drive, although it hasn't been touched.

"The disk you inserted was not readable by this computer" error message

Hello. I've had my iMac for a little over three months and I've encountered a strange problem. I play Warcraft III, and whenever I insert the disk into the drive, I get an error message saying "The disk you inserted was not readable by this computer" and it gives me the options to ignore or eject. I've gotten the same message with Starcraft as well. I also tried putting in the iPod Nano install disk with the same result. CD-Rs and Audio cds work smoothly though. I called Apple technical support and they told me to call 1-800-MY-APPLE to schedule an appointment with my local branch to bring it in. I just wanted to make sure no one on these forums can help me. All help is greatly appreciated. Thank you very much.
iMac (Early 2006) Mac OS X (10.4.6)

Steve, the original poster made clear he was on a core duo iMAC which ONLY runs OS X (discounting non Apple OSes of course!)
Therefore there is no extension manager. But I guess he would thank you for trying to help anyway.

Need help with Error message "The disk you inserted was not readable by this computer"

I got this message this afternoon "The disk you inserted was not readable by this computer" with the options to either "Ignore" or Eject"
This is in reference to my External Hard Drive "Buffalo" 1TB. I just got my Mac 27inch this week and when i got it i hooked up this hard drive to it, historically used on my old windows machine, but was still FAT32 formatted. I was able to upload all my pics to Aperture and music to iTunes. Was able to surf the data no problem.
This afternoon i noticed that it was no longer visible in the "Finder" and afre rebooting several times, got this message "The disk you inserted was not readable by this computer"
Neither the mac nor the HD was moved since yesterday, early this am when it worked.
Is there an easy fix to this? whats going on.
Some info:
I had used this external storage unit for more then a year.
I sold my PC today so cant test if the hard drive still works on that.
I have the latest 27 inch mac (2.7GHz)
Storage is connected to a power source ( I tried both USB and FireWire, both yield the same message)
Any advice?

Have you tried the Repair Disk feature in Disk Utility?

F this error message "The disk you inserted was not readable by this computer" with 2 radio buttons "Ignore" or "reject" It comes up every time I start my new printer. How do I get rid of it?

When installing my new HP printer I received the following error message when I inserted the software install disk: "The disk you inserted was not readable by this computer" with 2 radio buttons "Ignore" or "reject" I was able to eject the disk but the message remains. Now every time I start up the printer this error message pops up on my computer. I have since used the disk drive successfully for music CD's etc. How can I get rid of this message?

PRAM RESET
Zap the PRAM
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

first time posting so not sure this ended up in correct area...
I had same issue except only repairing the permissions didn't solve anything for me. *_If you recently upgraded your iTunes to 8.2_* check your permissions for errors, fix the errors, then restart computer and if that doesn't fix it, then try one of the 3 solutions below as there is a *known burn issue with the recent 8.2 update!*
My permission errors - permissions differ on ./Applications/iTunes.app/contents... etc, should be -rw-rw-r--, they are -rwxrwxr-x
I called Apple Care and we figured out 3 work arounds til a fix is released.
Solutions 1,2 are recommended by Apple Care. I used solutions 1 (easy) and then 3 (complicated).
Option 3 is a pain and takes A LOT of time and HD space or external HD if you have tons of music, podcasts, audiobooks, etc, loaded into your iTunes.
_*3 possible solutions:*_
1. Use the Finder window already built in the mac (to burn onto blank cds) -
Open Finder Window, go to File in the Menu Bar at top of computer, create a new Burn Folder, drag items to the folder and click on the burn icon inside the folder, insert blank disk when asked, add name, select burn speed, burn the cd.
2. Use the app Burn 2.3U -
Found at Apple.com in download section works like a Finder Window and converts audo files to MP3 automatically. (You can set up iTunes to do this as well)
3. Install an older version of iTunes 8.0.2 (couldn't find 8.1 thru 8.1.051) -
I found 8.0.2 at Apple.com, this process is complicated and you will need lots of HD space or external HD to do this because you'll want to back up your music library and you will need to delete version 8.2 BEFORE trying to install an older version. Otherwise stick with option 1 or 2 til a fix is released by Apple.
I ruined 8 blank cd's that actually burned but then I got the error message "the disk you inserted was not readable by this computer (Error)" at end of burn cycle and sometimes early disk ejections. _*I had no problems before the iTunes update in the past 5 days.*_ Still can't read/play the 8 disks but the problem went away!
I had burned 20 cds no problem last week with same media disks that were producing errors after doing the iTunes update, now after chosing to downgrade my iTunes I'm back to burning with no issues!
8.2 has 2 versions 32bit or 64bit, one of them may be PC/Windows version only but not sure which one I upgraded to or if that's even a factor with the permission errors I had.
Best wishes

Message on startup: The disk you inserted was not readable

Every time I start my computer I get a message: The disk you inserted was not readable by this computer. I've tried a number of things to stop it, no success. Anyone know how to fix this?

try safe mode, try booting from DVD or another boot drive and repairing the drive or checking for hardware errors like bad sectors.

Macbook Pro will not read CD. Comes up with the message "The disk you inserted was not readable by computer"

Is it a hardware problem or a software problem?

New message - "The disk you inserted was not readable by this computer"

Time machine was working just fine with my Maxtor external hard drive, once I had reformatted it, but this morning when I was booting up I got the message, "The disk you inserted was not readable by this computer." The message gave me the options of "initialize", "ignore", or "eject".
What gives? Why the sudden change? If I initialize, then I lose all the previous saves and defeat the purpose of Time Machine in the first place.
Any suggestions?

Do you still have a drive with Mac OS X 10.4 installed on it? If you do, you can see if the drive mounts in 10.4. If you get the same message, it might be a problem with the drive and not be related to TM. I had a problem with an external Maxtor drive that TM corrupted, but the drive mounted without any problems. I just couldn't write to it in 10.5.
If you can mount it in Mac OS 10.4 or on another Mac, see if you can repair the drive with Disk Utility or with a program like Disk Warrior. Another option you can try is to disconnect the drive and then reconnect it. If that doesn't work, try disconnecting it and rebooting and then connecting it again.
If you can get the drive to mount, copy the TM files to another drive and then reformat the drive. See this page from Seagate/Maxtor for information on formatting the drive:

Why do i get the "the disk you inserted was not readable by this computer" error when I don't even have a disk inserted?

Why do I keep getting "the disk you inserted was not readable by this computer" caution message when I don't have a disk inserted???

Unfortunately, I saw this error for the first time this morning. It's on my wife's iMac running Lion, and it appeared when the machine locked up on a Software Update screen prompting her to run an update (I'm assuming this was the recent Security Update).
After numerous failed attempts to force-quit or otherwise safely restart, she hit the power button, and when the machine came back up it failed to recognize the startup disk. I've since successfully restarted from several different (external) startup disks without incident, but each time I attempt to fix the internal drive via Disk Utility the disk shows only as "Media" and all the usual options to Repair or Verify the Disk are greyed out, leaving only the Erase Disk option.
Are we totally hosed?

"The Disk You Inserted Was Not Readable" Error

Hi, I inserted my External Hardrive into my usb port today and got an error saying "The Disk You Inserted Was Not Readable." I was wondering if someone could walk me through what to do. I went to do "First Aid" but I am not able to click either the "Verify" or "Repair Disk" buttons.
What can I do?
Thanks

It has to be formatted as Mac OS Extended (Journaled).
Do you have room on the startup drive for the stuff that is on there now - always assuming you get to it?
If so, copy the contents (if you are able) to your internal hard drive, format the external, and copy back.
Of course, if you do not yet have any files on your external HD the problem is over! Just format it!
