Software :: Booting From Disk And Still Getting Errors

May 10, 2008

I am attempting to fix my gf's Macbook Pro w/ 10.4. She had tried to reinstall the OS a few weeks ago, and I think the installation was bad.

So, her computer ended up not booting, and just sitting on the start-up screen.

I decided I would try a full reinstall, with formatting and everything. I backed up her files, and could not get them to delete from her harddrive using my computer (when linked via firewire). So, I booted from the disc, erased her drive, and formated in Extended Journaled.

I tried to install the operating system, on what I assume is a clean harddrive, but about halfway through, it keeps failing. I went into disk utility, and the harddrive says "verified" in the S.M.A.R.T section, but whenever I run verify, or repair, I get an error message saying "Could not unmount disk".

I searched the forum, and there are topics concerning this message when accessing disk utility normally, but nothing about this message appearing while running from the OS disc, on a fresh harddrive.

I have tried everything I know of (which is not much), with no success.

Could this error e the cause of OS installation failure? If not, the only other thing I can think of is that the actual dvd is bad, but it looks fine to me.

Windows On Mac :: Partition Errors In Bootcamp When Booting Vista?

Mar 25, 2009

I did the Bootcamp thing, partitioned the drive and installed Vista. Everything went well and Vista works just fine. But everytime I boot into windows, I get partition errors before it boots.

For example it says:

"Warning: Unrecognized partition table for Drive 80. Please rebuild it using a Microsoft-compatible FDISK tool (err=4)"

It will come up 3 times, and then boot into Vista. Both OSX and Vista are working fine, but something is definately wrong though since I am getting this error.

OS X Mavericks :: Disk I/O Errors With Mail Only

Jun 23, 2014

For the past few days, I have noticed Mail was running slowly - especially when starting.  Would take forever to start pulling in messages.  I looked for solutions and disabled non-essential accounts.  Then I took all 5 email accounts offline.  Still would get hangs and even beachballs today.  

I opened console and found that I was getting a LOT of disk1s2 I/O errors whenever Mail was opened.  The errors would continue until it was closed.

Note: This is on a mid-2011 iMac.  Disk1s2 is the internal hard drive.  I now boot off an SSD thunderbolt.  The internal holds all data; applications live on the SSD. 

I restarted the computer.  Then opened console and waited.  No i/o errors.  I opened every other program in my dock and got one i/o error when Carbon Copy Cloner was first opened.  I closed everything and then opened Mail.  It hung as usual and the I/O errors started coming.  I eneded up with 40 I/O errors in the 10 minutes that Mail was opened and (eventually) closed.  This was with all accounts set to offline.  

About this Mac: OS 10.9.3 2.7 i5 32 gigs RAM (I use Photoshop a lot and decided to max out RAM).  Ram has been there for over 1 year.

MacBook Pro :: Disk Utility Is Reporting No Errors?

Jun 23, 2012

My MBP has been reporting issues over the last few days and recommending that I verify the disk. Whenever I do this, it says that it finds errors and I should reboot with comamnd-r pressed and choose disk utility. Which I do. However when I try to verify the disk or repair the disk in this mode, it never finds any issues? Logging back in and running disk utility will again report issues and recommend repairing What should I do?

Applications :: Partitioning Time Machine Disk - Getting Errors

Apr 30, 2009

Disk utility doesn't seem too happy with adding a partition to my existing time machine disk. It has 750GB capacity, with over 200GB avail. I'm just trying to add a 70GB partition and it raises errors every time. I even tried using a mac that doesn't recognize it as a time machine disk, just a USB drive. Still no luck. I cant delete the data on this drive, so its important I just resize and partition without deleting. Any other options other than disk utility out there?

MacBook Pro :: Disk Errors Reappear Within Day After Repair-Hard Drive Dead?

Mar 6, 2012

Over the last few weeks, I have been experiencing crashes on my Macbook Pro. The crash would appear as such: I'll be using Chrome and all of a sudden pages won't load. The mouse continues to work, but if I navigate to the desktop, folder won't open. Then, if I try to quit programs, the dock either becomes unresponsive or programs will only quit if "forced quit." Then the beachball of death appears. The beachball of death will continue for a very long time—perhasp indefinitely, so I decide to manually power down the computer.  

I have tried to verify the hard drive in Disk Utility, and a few times I have gotten this error: Volume bitmap needs minor repair for orphaned blocksChecking volume information.Invalid volume free block count(It should be 46122698 instead of 42839276)The volume Macintosh HD was found corrupt and needs to be repaired.Error: This disk needs to be repaired using the Recovery HD. Restart your computer, holding down the Command key and the R key until you see the Apple logo. When the Mac OS X Utilities window appears, choose Disk Utility. So I restart from the system (command-R) and repair the disk. But now within a day or two I get the same error.  Does my hard drive need to be replaced? Am I on borrowed time? My computer is under warranty. Do you think Apple will replace the hard drive?

OS X V10.7 Lion :: Gray Screen After Restart - Permission Errors In Disk Utility

May 10, 2012

In fact I'm getting a grey screen when I just try to restart. Have run Disk Utility (which always finds Permissions errors - even though it appears to make repairs. Also, after erasing my hard disk and recovering my user data from Time Capsule). When I restart I don't get beyond a grey screen (with moving cursor). I can't install the update as obviously I need to restart in order to start the install process.

PowerPC :: Powerbook G4 Not Booting Up From The Disk

Dec 5, 2008

I'm having a problem with my Powerbook G4. I kind of screwed up my drivers because I was an idiot and tried to get some Intel drivers to work on the computer through some cheat thing and now my computer won't boot up. I have an install disk but when I try to reinstall it keeps saying that I need Mac OSX Install Disk 2. I never had to use disk 2 before and I never had one to begin with.

OS X :: Booting From Firewire Disk On Two Machines

May 19, 2010

I am trying to keep my work files with me for of site access � our IT folks will not let me access my desktop remotely. I don't want to use a laptop carry to and fro either. Instead, I am thinking about booting from a firewire 800 disk (7200rpm), and functioning from exclusively. I can take the drive with me, whenever I need to have all data with me at a home machine � more importantly I am hoping I can boot from the same disk on my home iMac and do what I need to do. I just tested it out for to see if the performance is acceptable � I can barely tell the difference! (perhaps a bit longer to boot - but that's about it). My work computer is 27" iMac Core i7 2.8GHz with 8GB ram and my home unit is 24" iMac Core2Duo 2.8GHz with 2GB ram. Will booting OS X on two different machines and changing files get me into troubles down the line? I know that some applications won't like it as they look at the MAC id for license authentication. Any other issues that I should be aware of?

OS X :: Booting Up From A Computer In Target Disk Mode?

Jul 12, 2008

I'm just curious if it's possible to put my Mac Pro into TDM, connect it to my MacBook Pro, start it up holding option to choose a start-up disk, and use the Mac Pro's HD to boot up. I'd experiment myself, but the Mac Pro is packed at the moment, and I'd like to know if anyone knows for sure that it will or will not work before digging it out.

MacBook Pro :: Tri Booting - Disk Error After XP Install

Dec 15, 2009

I'm having issues setting up a Tri-boot system on my Macbook. I can't figure it out at all. I've created the partitions, and began installing XP. After the set up, the machine reboots to finish the install, but I get a 'disk error: press any key to reboot' error after the install. I am not installing though Bootcamp, and I have insured the drive is an NTFS drive, as that is reason the disk error usually appears.

PowerPC :: G5 Not Booting Or Responding To Disk Repair

Jun 10, 2010

I have an iMac G5 that I have previously had both the HDD and logic board replaced by Apple. It has been giving me a lot of spinning beach balls lately and yesterday would spin when I did anything as simple as opening Safari. I had tried to repair the disk in Disk Utility, but it failed after a few minutes. Last night I restarted it and it got stuck on my desktop, but wasn't fully loaded. I restarted it with the Leopard disk and I tried both to "Verify" and "Repair" the disk and neither worked. This morning when I tried it again, the only option available was "Verify Disk."

When I do this I get the attached message. It is an iPhone pic, so I apologize for the quality. I'd like to get this figured out ASAP, as we are moving out of state tomorrow! My other thought was I could try to boot with the Leopard disk and do a Time Machine restore. I'm not sure if that would help though. I don't have anything TOO important on the internal HDD, but I would like the chance to pull it out and hook it up to another computer to sift through it. I'm afraid if I do the Time Machine restore something might happen and I won't have the chance to go through the HDD.

Software :: Time Machine Not Booting From Disk

Sep 22, 2009

I have had problems after latest update - parallels, airport loss etc. so I thought about restoring my mac with time machine, but after inserting leopard dvd, I only get the initial leopard "galaxy" screen, nothing else. Tried holding c key, via disk utility, etc. Cant boot up in safe mode nor single mode. Wondering wether it is because I am only using an external screen - the screen of my macbookpro went a long time ago.

Intel Mac :: Getting "Disk Is Full" Errors?

May 10, 2012

Yesterday we starting getting "Disk is Full" errors on our 1TB iMac. We have approximately 100GB of music, photos, etc., as well as the operating system and Office. It does not seem as if this should fill up the disk. In looking at the activity monitor, it shows that 999GB is in use, with 1GB free (approximately). While I was watching the activity monitor, it went from 1.7 GB free down to 1GB, while nothing was being (intentionally) downloaded.  Virusbarrier did a full sweep and returned no threats; spotlight turned up no files added or modified yesterday to help identify where the space is being used.

Software :: Powerbook G4 OS X Not Booting Up - Hard Disk Screen?

May 23, 2009

Here is the situation. I have a 12 in Powerbook G4 with OS X. About a week ago I downloaded a security update and once it was downloaded it asked to either restart or shut down the computer. I clicked restart. It shut down and then turned back on but only got to the Apple symbol with the small grey spinning wheel beneath and wouldn't finish booting up past that. I tried turning it on while holding down the option button and it went to the hard disk screen and clicked the right arrow but it still didn't get past that screen.

IMac :: Booting From Firewire External Hard Disk - Windows Drive

May 15, 2009

So here is my bright idea. I still may want to have Windows on my iMac for work projects *sigh* I think I came up with a solution, I rather not partition my iMac (when I buy it) 1TB drive for Windows. Don't want Windows on my main disk - I need the storage for Mac things, personal stuff etc. Is it possible to boot from a Firewire connected external HDD to run Windows?

OS X V10.6 Snow Leopard :: System Doesn't Restart When Booting For DVD For Disk Repair

Feb 25, 2012

I ran a disk check on my MacBook Pro which told me to run disk repair. Since this was my boot HD, I took out my Installation DVD, put it into the running system and started the installation file then selected that I wanted to reboot and start utilities. The system then rebooted, the "chime" came, and then, silence, gray screen with apple logo, nothing is happening. What do I need to do, to get further and repair my hard disk?

OS X :: Getting Tons Of .dmg Verification Errors

Dec 13, 2010

I just got my MBP yesterday, and so far it's been incredibly frustrating. Trying to download Firefox, 3 separate times, I get "image corrupted" errors when I try to open the .dmg. This is probably the 10th+ time it's happened today errors ranging from "invalid checksum" (from Facetime, downloaded from Apple), to "error -199". Any ideas what's going on? The same things appear to be just find on my Mac Pro, and they're running the same software. Already ran verify/repair disk multiple times.

Intel Mac :: RAM Errors Now It Won't Boot

May 27, 2012

My 24" iMac had some graphical glitches and froze up, so I ran MemTest86 on it and got a number of errors reported on my RAM. 

I had upgraded from 2x1gb to 2x2gb and kept the old RAM, so I gave that a try. This time MemTest86 itself came up with graphical glitches and reported problems on this RAM as well. 

I gave up for the night and the following morning when trying to boot, all I get is the monitor powering up and the Mac boot sound. The system then reboots immediately and does the same thing over and over. Screen powers on (stays black though) and sound plays. I never get to a gray screen at all nor does the Apple logo ever appear. 

Trying to boot to safe mode, off cd, single user mode are all unsuccessful, I never get out of the boot sound loop. 

NVRAM/PRAM reset attempted, likely unsuccessful. 

I've tried booting with 1 DIMM and 2 DIMM across the different RAM I have, but the same thing always occurs. Only time I get different behaviour is when booting with no RAM, and then I just get a beeping tone.
