Repair utility

I had difficulties when downloading updated drivers and features for my Epson Scanner. For various reasons (mainly my fault) I ended up installing - uninstalling - reinstalling a couple of times. Epson support have been very helpful and finally advised me to carry out a "Repair Permissions" via Applications >Utilities >Disk utility. I'm sure that their advice is good, but does anyone know what exactly
repair permissions achieves? Thanks in advance for your help.

Disk repair utility & printer issue

I will admit right now that until last night, have never touched an iMac but I have a friend that due to health issues, needs a hand. Can I ask a couple of questions of this forum?
1: She has an external Lacie H/D that is making wierd noises after being knocked over. Her backup software says to run the Disk Repair Utility. I haven't the slightest idea where to find this Disk Repair Utility, nor if I can run it on an external drive.
2: Her printer, mac book and iMac were recently moved from one location to another home. I need her printer connected wirelessly to both computers. I was able to get her Macbook connected but I am having issues with iMac. Can I uninstall her printer and reinstall? Not even sure how to do that basic process so advice would be appreciated.

Disk Utility should be able to check the LaCie - whether it will be able to complete any repairs that may be needed will become obvious when it's attempted. Disk Utility is normally in the Utilities folder within the Applications folder.
Regarding the printer, yes you can uninstall it in System Preferences>Printers & Scanners (or similar wording depending on version of OS X). The +/- buttons add/remove printers.
If you still have problems, post back.

Repair Utility for xServe RAID?

We have an xServe with an attached RAID consisting of four 350 GB drives. The drives are set up as a RAID. Due to storms/hot weather (air conditioning failed) the server restarted and the RAID powered down. The xServe is fine but the RAID is not functioning. From RAID Admin the drives all show up and are OK but the array is not showing up. Is there any disk repair utility that would be useful on a RAID?
xServe RAID Mac OS X (10.4.6)
xServe RAID Mac OS X (10.4.6)

The fact that it's showing up as spares is a significant problem. The host won't recognize it until the RAID recognizes the array. There is no separate utility to help you with this, other than RAID Admin.
What firmware version is on the array? If it's 1.5, there's a "recognize array" option that you should try. If it's an older version, I'd tell you it would be nice if you could have gone back in time and upgraded the firmware. Since that's not possible, you should call AppleCare (assuming you have got APS&S for Xserve RAID, or the machine is < 1 year old) and inquire about your options.

Repair utility says to load the disk, but no disk is provided.

The Lion comes as a downloard, no disk. But the repair utility says to insert the disk to to the repair.
I asked tech support if that were true. She said it was not true. I asked them to change the instructions to reflect what one really needs to do to repair the computer if it fails, and she hung up on me. (Really, no profanity, no insults, just a plain question. Must be a rough week with the Lion intro)
I still need to know if I need a disk available to repair the computer if it fails. Or how one would know how to repair it if it does fail without the disk and without the computer giving me instruction.
There is no written manual to explain. I am guessing that the we are presumed to be omnicient.

I've noticed that Lion creates a Recovery partition on your hard drive. Did the message say Repair or Recovery?

Purchased Lion, installed it - once I log in - i get the curtain and message to hold the power button till it shuts down. Worked with the disk repair utility - fixed permissions - still can't get past the "black curtain of death" any suggestions?

My machine was patched to date 10.x.x. I was lucky to get an internet connection and I selected the option to re-download Lion... its curruently being downloaded. What if that doesn't work?
Any thougths would be appreciated.

And you have a workstation? not a notebook.
Usually a driver or hardware, nothing that Disk utility will fix.

Drives stopped mounting with FW800, but FW400 is OK. Worked OK before, but won't now. Tried new cables, zapping pram, Disk Repair Utility. Any suggestions? Thanks.

If your external drive does not have an independent power supply, you may wish to consider a couple of lower-cost options before tossing the drive. Bus-powered drives have no external power source and must get all their power from the computer. They can exceed the computer's USB energy budget.
Cheapest option:
1 Meter USB 2.0 A to 5 Pin Mini B Cable - Auxiliary USB "Y" Power Design for external hard drives.
This gets power from two of the computers USB porst sna can provide enough power to wake up an under-performaing bus-powered drive.
If you don't have enough ports to use this, try the next cheapest option:
Newer Technology 7 Port Hi-Speed USB 2.0 Hub with Power Adapter for Mac & PC
Such a hub has a an independent power supply to make up for wahat the comptuer fails to provide.

Disk Repair Utility Full Disk Error

Today, my MBP froze, as in it no longer responded to keypresses or moving the mouse, so I held the power button until it powered off. Whenever I try to power it back on, it comes up with the apple logo on a gray screen, and a progress bar briefly appears beneath the apple logo, flashes a few times and dissappears, then the computer turns off.
By running the disk repair utility from the OSX install disk, the OSX partition of my hard drive needs to be repaired. When I try to repair it, it gives me an error saying that the disk is too full to do a repair on (I probably have ~10GB free, so this makes sense), and I need to wipe my disk and reinstall OSX .
I have windows installed via bootcamp and I can still boot into that and see my contents of the OSX partition (e.g. I can play my music, watch movies, open documents all of which are on the OSX partition, I just can't boot to it.).
Although probably unrelated, I've run the diagnostics, and everything came up okay. I've also tried holding shift during boot (trying to get OSX into safe mode) and holding command-option-P-R (clear the PRAM) during boot, neither of which helped.
My current strategy is copy a lot of data off my OSX partition from within my windows partition to an external HDD, in order to free up space on my OSX drive, so that hopefully disk repair can do its job. Does anyone know if this will work, or if not, can anyone recommend an alternate work around?

Backup your files, if possible. Your only recourse is to reformat the drive and reinstall OS X. Do not copy or backup files from Windows. If at all possible boot from another drive like your external HDD by installing OS X on the external drive (unless it is already a bootable drive.) You can then copy your data from the faulty OS X volume before erasing it.
You should never permit your free space to drop so low. One should maintain 10-12 GBs or 10-15% of the volume's total capacity, whichever is greater.
Since this problem will likely recur I suggest you consider just replacing the drive with one that is considerably larger. I would also be sure to arrange to maintain a bootable backup on an external drive in case problems such as this one occur.

My HP mini 210 will not boot up. The repair utility starts, but runs and runs with no results.

My HP mini 210-2080NR will not boot up. The repair utility starts, but runs and runs with no results. Safe mode start up also fails. Tried BIOS diagnostics with f10, memory passed, but HD startd but did not finish. Diagnostic log shows rusult 0303. Any ideas would be helpful. Thanks.

AW File Repair Utility 1.0

One more time, Please. Is there any value to downloading the AW File Repair Utility 1.0?
John

The note at the download site seems pretty unambiguous...
"About AppleWorks File Repair Utility
This utility is designed to fix AppleWorks documents that have become damaged when the documents are saved from AppleWorks 6 running on a Mac OS X 10.2.x client to an AppleShare or compatible file server."

WHAT REPAIR UTILITY CAN I USE BESIDES NORTON UTILITIES FOR MAC 0S 10.3.9?

I have been reading about the Disk Utility and repairing "repair permissions" and frankly I am confused. Since we cannot ue Norton Utilities for Mac OS 10.3.9. Is there a repair utility which will "deep fix" my hard drive the way that Norton used to before Panther? Some say Disk Warrior and some say Tech Tool. Which one is most effective or is there something else for Mac? Thanks.

Marcia:
In addition to Disk Warrior, mentioned in an earlier post, there is also Tech Tool Pro. DW does a great job of Directory repair and rebuilding. TTP repairs and rebuilds the directory in addition to hardware check, disk scan, files check, and files and disk optimization/defragmentation.
The first recourse, should always be, of course, OS X's own built in Disk Utility (Applications/Utilities/Disk Utility), for Repairing Disk Permissions and Repairing the Disk, along with other tasks.
ali b's links to maintenance sites also link resources for Unix Maintenance (also referred to as CRON cleaning) a very important maintenace item, and other very helpful utilities.
Sorry if this sounds a bit confusing. The sites ali linked have a lot of very useful information and I recommend that you check them out. May I, in addition, commend you for discontinuing the use of Norton.
Good luck.

Time Machine Backups external drive developed problem which the disk repair utility cannot fix, so suggested reformat. I can't reformat because the "Resource Busy". How can I reformat this drive?

My Western Digital external hard drive which I use as a Time Machine Backup stopped working. I tried repairing the disk using the Disk Utility program,but got the message that the utility can't repair the disk and to erase and reformat the disk. When I try that, I get the message the operation can't be completed because "Resource Busy", even though Time Machine is turned off. Any suggestions for repairing the drive/disk?
Thank you.

See Pondini's TM FAQs for starters.

Disk Repair Utility can't fix problem - help needed.

I have an external drive that I have been using with Time Machine. Last night I closed up the MBP and waited for the LED to start pulsing, then I unplugged the drive and packed stuff up. When I got home, I plugged the drive back in and opened the cover on the MBP. The drive icon was not on the desktop, and there were no other error messages.
I ran Disk Utility and did a "Repair Disk", which stopped after a few seconds with the following:
Verify and Repair volume “OneTouch4 M”
Checking Journaled HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Invalid sibling link
Volume check failed.
Error: Filesystem verify or repair failed.
Is there anything I can do at this point, other than erasing the disk and starting over? I don't THINK there's anything vital in the backups, but still I'd rather not lose them.
Walt

Yes, that's what I usually do. I was in a hurry, and I thought "If the disk is there when I go to sleep, and is put back before I wake up, I won't know the difference". Obviously not true - I guess the Mac is still doing stuff when it's "asleep".
Thanks for the tip on Disk Warrior - there's nothing on that disk that's worth $99 to me, so I think I'll just erase it and start over. It has only the most recent 2 weeks of TM backups on it, the rest are on my previous TM disk.

Is there an iTunes database repair utility?

Does iTunes 8 have the ability to diagnose and/or repair its own database? Is there another utility that can?

Sadly, no.
If your library ITL file gets damaged, your best bet is to use previous copy. I backup my ITL on a regular basis, because I don't care to lose 4 year's worht of ratings and playcouts.

Getting SUID has been changed and won't be fixed when using Disk Repair utility.

While attempting a disk repair, the first message that appears in the string is, "Warning: SUID file System/Library/CoreS...has been modified and will not be repaired." Is this a bad thing? If so, how do I fix it? My computer has been taking forever to startup and freezing quite often.

The long answer is that Apple doesn't update the permissions database at every system update. Since things change in the update that the permissions database doesn't know about, Repair Permissions flags them.
Repairing permissions is a long fought battle. There are those that do and those that don't. I think it's just voodoo. The only time I repair permissions is if I get errors indicating that a file cannot be read or app crashes when it is accessing something in the system level (if I can tell). Repair permissions only affects the system folders, not your home folder.

Disk repair utility

What do forum members like to use besides the disk utilites supplied with the mac to repair hard dive problems. are ther more rubust disk utilites out there???

Hi Chris:
You bet, I like DiskWarrior by Alsoft, and it gets excellent marks here in these forums, so I think for HD corruption/Directory rebuilding, its 'king of the hill'. I also use TechTool Pro 4 (Micromat) and iDefrag (Coriolis) as well as Drive Genius & Data Rescue by Prosoft Engineering. Each have their strengths but if i had to choose just one it would be DiskWarrior.
