Verify disk said disk needs repair?

Hi guys. I ran a verify disk in Disk Utilities as my MacBook Pro 2010 has been sluggish over the few months. After it ran verify disk, it said there was an error (it needs to be repaired) and that I need to start my laptop with recovery HD to fix it. Is recovery HD going to wipe out all my data? (I have a time machine back up, so it's fine). Also, is it really necessary to restart with recivery HD? If I leave my laptop as it is, will things get worse? One more thing, what's the cause of the error in my HDD? Thanks in advance!

It shouldn't lose any data but since the drive is having problems you may have already lost data. On very, very rare occasions repairing may make things worse.
Yes, you have to boot from your recovery partition to repair the drive.
Things might get worse. We have no information on what the error is so we can't answer this or your last question. It may also not be traceable to a particular cause.
You do say your ocmputer has been slow. This can be the result of overcrowding a hard drive. You should have at least 15% of your drive space free at all time and at least 20GB or so. If you don't then that could be the cause of the errors. It's like trying to work with a desk with no clear space and then being surprised when you cannot find a paper.

TM disk needs repair but won't unmount.

Hi,
I've been having problems with this TM disk since new but I can't work out what to do. The disk is a Seagate 1.5TB with my MacPro backed up to it and a sparse image on it as my MacBook backup.
The disk only has one volume on it. It has done strange things in the past like return an error on the initial backup of the MacPro after about 900GB of data and when I wiped the drive and tried backing up again it returned an error at about the same stage. Subsequent incremental backups worked so I continued to use it but I have never been able to eject the drive. I have always got the "something is using it" dialog box. I could only safely power it off by restarting the MacPro and turning it off before it booted. I checked the disk in disk utility and it said it needed repair but could not be repaired. After hearing about trouble with these drives I returned it for a replacement. I got an error on the first backup again with the new drive but subsequent incremental backups were OK so I left it. I checked it in disk utility yesterday and it said it needed repair but would not unmount for the repair. I have reset the FW800 port in the past and that didn't seem to make any difference. Other drives in this enclosure (SOHO Tank, Oxford chip) work and unmount OK. I don't know whether this is a TM issue or I've got another flakey drive. I'm tempted to send the drive back to Seagate again as I don't feel secure with this as my backup.
Also, occasionally when I go into TM via the TM icon in the dock, I only see backups up to the day before yesterday in the timeline at the side. If I cancel TM and relaunch I get the full set in the sidebar (yesterday and hourlies for today).
Any thoughts?
Thanks,
Brian

If possible, you should partition the drive, so the MacPro's backups are in their own, exclusive space. If you ever want or have to delete them, it will be extremely difficult and take a very long time. See #4 in the Frequently Asked Questions *User Tip,* also at the top of this forum.

Try repairing it from the copy of Disk Utility on your Install disc. (Boot up from it, select your language, then on the next screen select Utilities from the menubar, then +Disk Utility.)+

I have repaired startup disk in disk utility but still get message saying startup disk needs repair, help.

I am on a macbook pro running the latest version of yosemite. I was going to use Onyx to clean it, but I got a message stating that my startup disk needs repair. I command R went to disk utility to verify and repair and the disk was fine. However, I still get the same message when using Onyx. What should I do? Should I command R and reinstall? Will the fact that my startup disk needs repair cause a problem?

Thank you @EricRoot, I think you may be correct. I don't get that message with other programs. However, I did locate files on my computer taking up way too much space...

False Disk Needs Repair?? Help Please!

Every maintenance app I have (MacPilot, Onyx..) keeps telling me my disk needs repair BUT when I put in my install cd and go into disk utility and do a verify disk it says my volume is okay... I am confused.
I can not run a verify disk with disk utility however, when logged on. It goes unresponsive and I have to force quit.
Also if I try to run a verify permissions while under disk utility running on the install cd, I get an error that there is no catalog??
Any help would be greatly appreciated before I make The Call for help.

I booted up to my install disk and ran disk utility verify disk and it passed.
My problems however have multiplied since my first post beyond getting that "volume needs minor repair"... my Pioneer optical drive won't read my install disk (spits it out) or any dvd formats, it only reads music cds at this point.
In fact it stopped cold reading in the middle of running disk utility from my install disk. I had to power down and power up just to get the disk out.
Methinks I have a problem requiring a trip to the Apple store.. ugh.
I always backup daily, with Time Machine and another backup program, just in case this happens.

Airport Utility says "Internal disk needs repairs".

I've had my Time Capsule for quite a while, and never had any problems with it. I keep my iTunes library on it, which is around 130GB of music. Recently, I had my iPod that held all my music had a hard-drive problem and I had to get it replaced and haven't received the new one yet. So the only place my music library is is on the Time Capsule. Lately it had been giving me problems while I was copying files in iTunes to it, and would disconnect in the middle, but when I unplugged it and plugged it in again (resetting did nothing) it would be fine until I was copying files to it again. Today, it did this multiple times, and then Airport Utility popped up saying the "internal disk needs repairs". I've read other people who had this problem, but the only thing I can find is that they had to erase it and then it was fine. I have the music library backed up on CDs from a few months ago, but I would really prefer to have the complete one as it stands now. Is there any way for me to fix this problem without erasing the entire hard-drive? I want those files!

Welcome to the discussions!
Open your Hard Drive and look for your Time Capsule on the left under the SHARED heading.
Click the TC icon and a TC folder will display to the right.
Double click this folder to display the xxxx.sparsebundle files that contain all of your backups.
Double click on the xxxx.sparsebundle file for your computer. If a window pops up with a "skip" option, click "skip". A white disk image of your backups will appear on your desktop in a few minutes.
Open Hard Drive > Applications > Utilities > Disk Utility
Select your backup image in Disk Utility and click Verify
Depending on how large your backup is, it may take hours for Disk Utility to check your disk
If Disk Utility reports errors, click Repair to see if that will fix the issues.

Booting with DVD problem!!! Disk needs repair

Hello,
Ran disk utility and I got the «disk needs repair» error. Please boot from install DVD
Okay no panic I try to do it.
First try holding C key and with the snow leopard DVD (retail not the one I got with the computer) = failure keeps me on the apple window
Tried it with the DVD I got with the macbook pro while holding the C key again = faileure keeps me on the apple window
The computer works fine except it tends to bog down
I'm running lion and my macbook pro is less than a year old
I also have Norton antivirus (because YES there are viruses again - anyway norton told me there were when I scanned my HD a while back -). I tried disabling it totally and tried the same things but to no avail...
Can anyone help? Have I overlooked something obvious? Or is somehting more complicated necessary?
Thanks in advance

If you've installed Lion, the 10.6 disk won't help you. You need to hold down Command-R during boot to bring up Lion recovery ... you can then run Disk Utility.
Oh, and agree with Allan, dump Norton. If you want an antivirus, install ClamXav from http://www.clamxav.com

'Disk Needs Repair' warning on base station w/ Hitachi 2TB USB Drive

Trying to use my new 2TB USB Hitachi XL Desk Drive (mac formatted) on my extreme base station. Drive works perfectly on my MacBook Pro but when I plug it in to the base station both with & without a powered usb hub, airport utility says 'Disk Needs Repair' & amber light flashes. Disk shows up in utility as a 1.8TB Hitachi but disk title is not listed. Other drives work just fine on the base station. Not sure what else to try at this point.

Connect the drive back to your MacBook Pro.
Open Applications > Utilities > Disk Utility
Click on your drive on the left side of the window to highlight it, then click Repair Disk over on the lower right of the window. May take 30-90 minutes or so depending on how much data is on the drive.
You may also need to click Repair Disk Permissions in Disk Utility as well.
IF...you are using the drive for Time Machine backups, Apple does not support backups to a drive at the USB port of the AirPort Extreme. You will have issues if you try this.

7.5.2 Firmware Update causing Ambar Flashing / Internal Disk needs Repair

I just updated my firmare to 7.5.2 on my 2TB TimeCapsule, and after a couple of days my access to the TimeCapsule feature stopped working because I got a message theta says: "internal disk needs repair".
I been noticing that a lot of people here, in the forum, are having the same problems. I have tried downgrading to a previous version of the firmware to no avail. It's really dissapointing because there really you can do but wait for a solution from Apple, because you information is being held hostage until there is a solution. If any body has a better solution please help!!!!

FMPENA27, welcome to the discussion area!
If you are getting a message that your "internal disk needs repair", you might consider repairing your internal disk.

Time Capsule - Internal disk need repair message

Hey.
Got TC -2 TB version with latest firmware.
was used to be my media server.....formally
now it's just white box...
suddenly one night , wasnt able to connect to TC, on check green light was active..
but wasnt communicating and internet was down.
did restart- power down and up.
after that HDD not showing in finder window at all, and airport shows "internal disk need repair" tried few things but no luck
any idea to recover datat, how reliable is diskwarrior, data recovery softwares. can they see unmounted disk at all????
help.

All hard disks have stated MTBF.. Mean Time Between Failures.. but that is Mean ie average.. some disks go early and some go seemly forever.. but 50% of the disks will be dead at the MTBF point.
A TC that is only 7 months old is under warranty.. Apple will replace the TC for you. They will not recover data.
If you have data on the TC it should only be Time Machine backups which means they are not important if you immediately make a new backup to another target disk. If you copied files to the TC without making backup you are very naughty.. you broke the rules.. that you never ever trust files to a single location. Now you have to pull apart your TC voiding the warranty (although if you do it carefully who is to know).. remove the hard disk and attempt recovery.. !! It is usually a simple loss of format.. tools like mentioned above can fix that and recover the files.. if not you send the drive to a data recovery centre where your data is mangled and recovered as best as they can do.. at a cost of around.. $500-1000 depending on size and problems.. get a quote first.

Computer says disk needs repair

My laptop keeps on saying the disk needs repair or back up. I have done the backup disk and the problem still continues.

Your hard disk may be starting to fail and will have to be replaced.
What model is your laptop?
Are you still under warranty?

AirPort disk 'needs repair', Disk Utility finds nothing wrong...

I have a 640GB hard disk that was just formatted for use as an AirPort disk. I zeroed the disk on my PC and then formatted it in Disk Utility while it was attached to my USB hard disk dock. Because the original partition scheme I tried to do would not format as specified (i.e., Disk Utility decided that since I put free space as the first partition with four partitions, that what I really wanted was just the three partitions), I repartitioned the disk as follows: 64.00GB for HFS+, 32.00GB for FAT32, 512.00GB for HFS+, 32.00GB for FAT32 (using Master Boot Record). After this completed, I ran Windows XP on my PC and diskmgmt.msc with the intention of deleting the first partition 64.00GB HFS+ and replacing that with 64.00GB NTFS. This seemed to work fine on Windows XP, but I could not do it on Windows 7 because Windows 7 automatically makes the last partition on MBR an Extended Partition without asking if you want it to be a Primary/Extended Partition. Next, as I only intended to boot this on my old PC, which I rarely use, I installed Windows XP on to the first partition (now 64.00GB for NTFS). The installation went fine, as well as the software I installed in Windows that will allow me to see the HFS+ partition from a Windows boot. This software recognized the partition and mounted it in Windows. Next, I shut down the PC and put the disk back into the USB dock to see if all was well from the Mac side. Disk Utility did not report any issue with the disk and was able to see and mount all of the partitions correctly; however, when I attached this disk to my AirPort Extreme, the light started blinking amber and, upon further inspection, was told that the "AirPort disk needs to be repaired". I went back to Disk Utility and verified the disk without issue, but no problems were found. To be complete, I also repaired the disk in Disk Utility, but still it seemed to find nothing wrong and the repair had no effect on the AirPort error message. When I attach the disk to my AirPort Extreme, it will only mount the two partitions that are FAT32. The HFS+ partition does not show at all. I understand that the NTFS partition will not show over AirPort, which is why I chose a small size for it. My main reason for creating the NTFS partition is so that if I ever have a problem with my AirPort Extreme or need to work with a large file, I will have faster access if it is on a SATA connection inside my older PC than over WiFi or connected to my USB hard disk dock. Windows XP does not recognize the default OS X partition type, so that was not an option. Any assistance on how to address this issue would be greatly appreciated. The applicable operating systems are: Snow Leopard (my Mac mini), Windows XP Pro SP3 (on the old PC) and Windows 7 (on the newer PC that is attached to the AirPort Extreme).

Hi, i had experienced the same issue. After resetting tc to factory settings and reconfiguration everythings works as before.

Disk Needs Repaired

I noticed my HD making a weird noise today so I ran Disk Utility's Verify Disk and got a message saying I need to repair my disk. I don't have my installation CDs at hand to do run the Disk Utility from that disk (I'm a college student at home for the holidays and most of my software is back at school). And I only have non-Intel versions of Mac OS X installation disks at home. I have shut down my computer and don't plan on using it until I get a solution figured out that I'm sure will work. Don't really know what my best option is now is there any way to get Disk Utility to repair the disk w/o using a bootable CD?

Hi and Happy Holidays!
You can try booting up using the Single User Mode (fsck) by restarting while pressing Command + S until you see a black screen with text prompts, do a search here to find the detailed procedures.
If that doesn't solve your problem; Check your (launch) Disk Utility, what does the S.M.A.R.T. status say, "Verified" or otherwise?
What kind of weird noise is it making, can you be more detail? Is it like a "tick tick tick" that constantly ticks? That may signify an imminent hard disk failure! (regardless how new your mac is) the good news is if it is new and within a year of purchase, or if you have AppleCare extending to 3 years, Apple will replace your HD with no charge.
If it really is a hard disk physcial failure, no hardware test nor disk utility would be able to correctly pin-point what is wrong.
Invest yourself in an external FireWire hard drive of same or larger capacity, use SuperDuper and clone your internal drive to the external, it is even bootable... so when you get a new replacement disk, you don't have to reinstall and re-configure ALL the settings, you just use the external back up clone and "clone" back your drive!
Cheers

Disk Utility - Verify Disk Permissions / Repair

I run Disk Utility > Verify Disk Permissions with this rsult:
Verify permissions for “Macintosh HD”
Permissions differ on "usr/share/derby", should be drwxr-xr-x , they are lrwxr-xr-x .
The following repair was successful.
A few minutes later I run Verify Disk Permissions again with the SAME result:
Verify permissions for “Macintosh HD”
Permissions differ on "usr/share/derby", should be drwxr-xr-x , they are lrwxr-xr-x .
What does it mean and how can I stop this error?
Thanks!

There is nothing in that message that requires repairing. That is why it keeps showing up.
The permission database has to be updated every time the system is updated. If they miss a change that they have made in the system, it will get flagged as you see, but doesn't mean anything is wrong.
That KnowledgeBase article also must be updated to reflect the things they missed.
All that message is saying is that the directory derby is now replaced with a link to another directory (the l vs the d). However, mine doesn't have a link. Did you install anything that might have updated derby?
If you open Terminal and enter this code, can you post the line that has derby on it?ls -al /usr/share/
I'm repairing permissions now to see what pops up for me, but that will take a little while.
Edit: I looked into the Derby directory and Derby is a Relational Database Management System used by Apache. So, did you install something that modified Apache, PHP, mySQL or something like that? It might have altered the link.

Setting up AirDisk - amber light - "Disk needs repair"

Hello all - I am unsure if I am posting this in the correct section, because I don't know what the problem is!
I have a 1TB external HD that I am trying to use as an Airdisk. I have used it in this fashion a good while ago so it has worked. I have the disk connected to my AEBS, and the light flashes amber, telling me that "There is a problem with the disk connected to your Apple wireless device. Connect the disk to your computer to repair the disk."
However when I connect it to my Mac, it tells me that the disk is fine and not in need of repair. I have tried repairing permissions on my Mac and also checking of the disk on my Mac needs repair. This doesn't seem to have helped.
I am using firmware 7.4.1, and also tested it on 7.3.2, but it didn't make a difference.
Any ideas?
Many Thanks!
Ian

I also had this problem once and my solution wasn't anywhere near as sophisticated as speakerfritz'....I eventually had to start from scratch again, do a hard reset, and re-format the disk. There wasn't a problem with the physical disk itself.....obviously I had to re-back everything up again, and also replace the files i had sitting on it......
Next time I'll try speakerfritz' method first....

Disk need repair several times a week

Hi, guys.
My device is rMBP late 2013. I update to Yosemite at first time when it released.
A month ago, I find my mac so slow, and I verify disk in Disk Utility. Verify was stopped with many error about disk.
I restart Mac and press command+R into recovery mode, and repair disk. It works but something was wrong after repair.
Disk Utility report many wrong code, but I can't find the reason even one of them. I just repair disk again and again.
What's wrong with my disk? And can I find the reason about this?
Thanks a lot!

The most recent update, Macbook Pro Retina update 2.0, jacked things up, I heard Apple pulled the update from their servers so that others don't update to it that haven't, but for us people that did, we just have to reset the SMC until Apple pulls the thumb out and release an update to fix the issue.
