Disk Not Readable? What!

Aloha all. I searched for info in the Tiger forums, as well as here before posting, but came up empty so I'm gonna start a new topic. Here goes...
I copied a bunch of songs (all legal downloads, & imports from my personal cd collection) and burned them to a DVD disk, which is an option from iTunes. Burning went smoothly, not to long, etc.. I then re-inserted the disk later in the day, and got "disk is not readable, would you like to reformat, yadda, yadda. My question is why would a disk that was burned on my mac not be readable on the same mac that burned it? Part two. Is there a way to fix this bizarre behavior?
I did a little experiment and did the same procedure using OS9 on my son's G4 and it worked fine. Any info, tips, suggestions would be greatly appreciated.
Mahalo in advance, JB

Anyone?

Disk not readable - now programmes freezing

I recently used a new GoFlex Seagate external HD and had problems with it from the outset - perhaps I didn't format it correctly for mac. Statered getting 'disk is not readable', eventually sorted the disk out with disk utility so I can use it but kept getting the disk not readable alert even if the disk was not inserted. I've zapped the PRAM and reset the SMC, now not getting the disk alert but the compter keeps freezing. It only happens in some programmes, usually in Lightroom 4 which I use 90% of the time. I have to do a force shut down, then it'll work fine for about 30 min before freezing again. Seems fine if I just use it with Chrome.
Many thanks for any help you can give.

Weird.
You did some good troubleshooting. How stable does it feel when you boot the computer to safe mode?
Also sometimes stability issues can be user specific, so maybe its not the program itself causing a problem or the operating system. But maybe something else like start up items, or your user cache and plists may need to be troubleshot.
There was something I had seen from Apple about how to do safe mode and what it is lemme see if I can find it.

this will show you how to create a new user to test with. The instructions are for 10.6 but the steps are the same.
Lemme know how it goes!

Hard disk not readable by this computer

I have 2 identical WD2500JS HDD in my Mac Pro. Both worked fine for sometime, but now I'm greeted with an error message every time at boot up and the 2nd drive isn't usable/mountable/readable at all.
The drive appears in the Disk Utility as "Media" and Disk Warrior can also see the drive, but I'm unable to see any partitions, it's size, repair it, etc..
Disk Utility and Disk Warrior claim S.M.A.R.T is not supported on the drive, not sure if that matters (the other disk correctly supports it).
I'm not sure what I can do to recover the data on the disk or if the disk is permanently damaged.
Thanks for your help.

Sorry to hear. TechTool Pro 5 does an excellent media scan job. And it should be a warning to make backups more often, and more sets, two or more.
TTPro also has pretty good SMART test suite (Intech Speedtools probably has the best), though SMART "ain't" that smart.
I replace drives every two years or so, use the older drives for backups.
First I'd pull them, put them in FW case for SATA drives, and give that a shot. And you'll need disks to recover to, to replace them (even if you repair or are able to zero out or 7-way write - OS X tools are not that hot for mapping out bad sectors).
Disk Jockey is $500 but does full sector copy (no computer needed).

"Disk not readable...", Verify & Repair fail, Zero Out, HFS+ still fail

First, a time machine error came up saying the volume could not be found. Tried disk verify, disk repair (in disk utility) restarting, reconnecting, but to no avail. On restarting, computer says "Disk was not readable by this computer." I then Zeroed out all the data and reformatted the drive to Mac OS Extended (Journaled). TM worked for most of the day until tonight when another error message came up saying that the next backup failed because it required 168GB, but only 49GB was available. Yet I had done virtually nothing since the last backup the hour earlier. I clicked "Back up Now" to try and get it to maybe re-evaluate the situation and maybe do the backup, but instead, I get the error that I got before - "The volume could not be found" (or something to that effect). Upon restarting, I again get "The disk you inserted was not readable by this computer".
Is there something I am doing wrong? What can I do to fix this, or prevent this from happening later?

This is what the error message was before, and is what it is now.
You had these sorts of errors, then zeroed-out the drive, now you have them again?
There's only one conclusion: your drive is failing. They don't always just crash and burn.
Note that the volume name should be "Time Machine", but Disk Utility sees it as "disk2s1" for some reason.
That's it's internal name to OSX. Use +System Profiler+ (Apple menu, +About this Mac,+ then +More Info.+
Look in the sidebar for FireWire or USB (whichever it is), select it, and you'll see disk2s1 listed as BSD name.
Time Machine Buddy seems to freeze most of my other widgets (can't type in calculator, can't delete Time Machine Buddy). It doesn't seem to do anything either, It just sits there saying "Backup Status" and "Messages" but no messages, just "....".
That's not normal, if you've had a successful backup recently, or one currently in progress.
An earlier post had a similar problem, because somehow he didn't have permission to read his own system log. From the Finder menubar, select Go, then +Go to folder,+ then type /var/log
That should list, among other things, system.log Double-click it. If nothing shows in the center portion, post back and we'll fix it.
But your main problem is an unreliable drive.

Need help with Mac & PC not recognizing external drive (disk not readable)

I am having trouble getting my computer(s) to recognize my Seagate External Drive.
Have tried on my MacBook, iMac, 2 Mini's & my roommate's PC and all reveal the same issue: The Disk you inserted was not readable by this computer.
MacBook/iMac both are working off of Leopard
Both Mini's are on Tiger
It won't show up in finder, rendering it unobtainable. I need to get the information if at all possible off of this hard drive (very important!!) so any help I can get would be greatly appreciated!
It allows me to go into disk utility where it shows up with this information:

And it is in the "about this mac" section with this information:

Additional info:
on the disk4s1 info in disk utility, this information is seen:

Mount Point : Not mounted
Connection Bus : USB
Device Tree : /PCI0@0/USB7@1D,7/@4:1

so it looks like a whole lot of no's that need to be turned around! I can't understand why it won't be read by either Mac or PC with all of this, or how I can fix it

External Disk Not Readable by OSX after Setting Drive Letter in Windows 7

My external hard drive, which was previously formatted as Mac OS Extended (Journaled), contains all of my purchased music. I have this external drive connected directly to my iMac via USB. My iTunes in OS X points to this drive.
After installing Boot Camp, I was able to read this external hard drive in Windows 7, but I changed the drive letter used in Windows 7 from E: to G:. Bad idea, apparently...
Now when I boot into OS X, I can no longer read the drive (although I can read it in Windows 7 just fine). I get the error message:
"The disk you inserted was not readable by this computer." [Initialize] [Ignore] [Eject]
When I use Disk Utility to attempt to Repair Disk, I get the following error:
"2010-11-24 08:43:41 -0800: Verify and Repair volume “disk2s2”
2010-11-24 08:43:41 -0800: Starting repair tool:

2010-11-24 08:43:41 -0800: Error: Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files."
I've searched for this issue in these forums and on the web and have not yet found a solution.
Is there any way to repair this external drive so that I can again read/write to it in OS X (WITHOUT losing my music)?
Thanks!

I had this exact problem. I bought a 1 TB My Book, formatted it with Disk Utility, and completed a successful backup. I also had some home videos on it and was using about 40% of the drive. One day, about a week later, I had the same "disk unreadable" message and soon panicked. Tried everything, but finally spent $100 for Disk Warrior and I was able to get my videos off, but it wasn't able to fix my drive, DW said I didn't have enough memory.
I reformatted and put my videos back on, but now will use a different drive for backups, so if it fails again I only lose my backups.

Disk not readable

I found a post with this same problem but no one responded. Thought I would try again. I have a CD-R of grandson's baseball photo's. When I insert the cd I get the message "The disk you inserted was not readable by this computer". It was created on a Windows computer. I might understand if it said I needed a certain application to open it. Any suggestions out there?

There could be several different issues that cause this problem.
Many of the softwares for CD and DVD burning have different functions and many don't have those functions at all.
Software for burning should have these features.
You have the option to create
DATA
AUDIO
VIDEO-TS
Besides this the software should also give the option to create your project for
PC ONLY
MAC ONLY
PC OR MAC Compatible
Most good softwares will
Read the project
Compress (If need be)
Write the project
And last but not least
VERIFY
Verify closses or finalizes the project.
If the project was burned on PC only that could be the problem,
If the project was burned on entry level software without these options, the settings could have been set wrong.
If the project was not Verfied that could also be the problem.
Lastly if the project was burned on media that your computer is not capable of reading.
I suggest you get a friend with a PC to try it out, and if he or she can play it on a PC then have them reburn the project with good Media, and Good Software.

Recovery process stuck (the disks not complete), what shall I do?

I have a Lenovo T60 2613. Now I am ready to sell it, and found three recovery disks made by my husband. However, it turned out that disks are not complete. The system asks me to put one more disk in to complete the process, but I couldn't find the disk.
Now my computer is stuck. Every time I turned it on, it will go to the recovery page. And I have to put the power button to shut it down.
I wonder what I should do in this case. Any advice? If I buy a complete set of recovery disks, would that work? Thank you.

Hi there , Thank you for visiting the HP Support Forums and Welcome! This is a great site to get answers and ask questions. I read that you had received an error message saying that the recovery did not complete after it had created approximately 90% of the recovery file. As per Microsoft only one recovery file can be created. Here is a document for you called Creating a Recovery Image on Discs or Saving a Recovery Image to a USB Flash Drive (Windows 8). It will give you the best information about Recovery, Options available, Error's etc. Here is another document for you called Obtaining HP Recovery Discs or an HP USB Recovery Drive just in case you need it. Best of luck! Have a great day!

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 went to back up my Mac on the same Seagate Free Agent I've been using for a year, but I got a message "the disk you inserted was not readable by this computer." I'm still using Snow Leopard like I've always been. What is going on, and how do I fix it?

I went to back up on the Seagate Free Agent I've been using for almost a year. I got the message, "the disk you inserted is not readable by this computer." What do I do now? How can I fix it?

10.7.4 is not Snow Leopard. 10.7.4 is Lion.
Also, is the drive connected via USB or Firewire?
If USB are there other devices on the USB bus?
Are you using Time Machine, Superduper, Carbon Copy Cloner, or another software?.

External Hard drive "not readable", does not show up in Disk Warrior either. Help me, please!

I have a 500gb G Drive Slim that is almost brand new. I accidentally pulled the cord out when it was connected, and now when I try to open it, it says "not readable by this computer." This is what I see when I go into disc utility:
I called G Drive, and they told me to download Disk Warrior 4. I did, and this is what I see when I open it:
My hard drive doesn't show up...i'm not sure if i'm doing something wrong but I just paid $100 dollars for this and I'd really like some help. I read the manual and it wasn't helpful at all.
Please help me!

Make sure it's format is Mac OS Extended (Journeled).
To check it's format, plug in the External HDD and search Disk Utility in the spotlight. Click the External HDD and go to the Partition tab. If it isn't Mac OS Extended change it and format it.
You shouldn't need any of these external applications to use it. I have one and use it like a flash drive.

Whenever I plugged in HP laserjet M1132 printer usb to my Macbook air,a screen pop-out "the disk inserted are not readable by this computer".I uninstalled

Hi,I'm new here and I think my problem were discussed few times before.However,I tried to follow the solutions similiar to my condition but it does not work.My problem is whenever I plugged in the HP printer (Laserjet M1132 MFP) usb to my Macbook Air,a screen will pop-out and read as 'the disk inserted is not readable by this computer'.I even bought my Mac to the Mac store but the situation remains the same.Okay with other printer but not with my HP.Sigh.The HP printer worked just fine with other computers (not Mac).I'm really sick of it.Please help me.I once plugged in an external hard drive & started Time Machine with it.The printer problem started after that.However, the hard drive plug-in works just fine.
Your attention of above matter is highly appreciated.Thank you.

Here is what worked for me:
I reset the System Management Controller on my MBA. To do so requires shutting it down, keeping it plugged in to power (I also unplugged both USB connections), and then from a powered off state I simultaneously pressed Shift + Ctl + Option + Power (I did this once and it did not work so I tried again and did it 3 times just to be safe), then released them at once, then I pressed the power button. Problem solved.

I also tried uninstalling the using the repair Disk Permissions with Disk Utility and moved the HP Printer software accessories to the trash (you can search the web for how to do that but that did not solve the problem either). Neither of these options worked.
