Disk Utility won't let me do anything with broken flash drive?

Hi there,
I own an 8GB SanDisk flashdrive that recently, and out of nowhere, changed permissions to write only. I feel like this may have something to do with the fact that when it was in my old Macbook I would close the screen with it still inserted and it would eject itself and the drive has possibly become corrupt because of this happening one too many times? Anyhow, when moving files around and to my new Macbook and what not, I tried to move some from this USB and it wouldn't let me. I eventually worked out that it would let me copy the files and paste them elsewhere, but now I have this flash drive with a bunch of files that can still be read and I don't know what to do with it because it won't let me delete them either. When I try it comes up with "The item can't be moved to the trash because it can't be deleted." I've tried Disk Utility and this is what happens under the First Aid, Erase and Partition options
I've also tried the appropriate commands in terminal to try to get the disk utility to respond and I kept recieving error messages there too. Also, when I click on the volume underneath the disk it shows all the space that all the files that are very much there are taking up but then also says there's zero files.
Anyone know what on earth is going on?! I mean I know the USB has probably just had it but I'm wondering if there's any possible way I can repair or erase it at this point?

I suspect that the USB is dead. This is the result I get when I insert my USB drive formatted the same as yours:
Note that the options are not grayed out.
You might connect it to a PC, if available, and see if there is any difference.
Ciao.

I got some help from an apple assistant on the phone. It is kind of round about way to get in.
Here is what he said to do and it is working for me...
a. on the device that is asking you for the security questions go to "settings", > "store" >
      tap the Apple ID and choose view"Apple ID" and sign in.
b. Tap on payment information and add a credit/debit card of your preference then select
      "done", in the upper right corner

d. At this time you can remove the card by going back in to edit the payment info and
      selecting "none" as the card type then saving the changes by selecting "done". You
      should now be able to use your iTunes store credit without answering the security

It's working for me ...I just have to put in my 3 digit security pin from the credit card I am using.
Good Luck friends!

The Get Info. fields show up gray if the files is locked and iTunes knows it can't edit the file. Make sure the files are not marked as read only and, if necessary grant both your account and system full access to all files and subfolders of your media folder.
You can set Part of a Compilation for multiple tracks from the Options tab of Get Info.
See Grouping tracks into albums for tips on getting iTunes organized.

Updated to latest operating system on MacBook Pro and now won't let me drag files onto a flash drive.

Updated to latest operating system OS X Mavericks on MacBook Pro and now won't let me drag files onto a flash drive.

The Flash Disk must be NTSF formatted. Writing to NTFS requires 3rd party drivers (Tuxera, Paragon). Reading from NTFS however does not require these. So install NTFS drivers, or format the drive in FAT32 from Disk Utility.
Hope this helps :-)

Disk Utility won't let me erase or change the partitions on my external USB hard drive. What should I do?

I can't use the 'erase' function in my disk utility program or set up different partitions with my external USB drive. As I am able to do this for another external hard drive, I assume the problem is not a software problem but connected to this specific USB drive. However, I wonder what other options do I have? Is there any software that can 'force' a complete deletion of everything of the USB drive?

That or another Mac OS X installation.

Disk Utility won't let me format external drive to FAT32

Maybe this cannot be done or the answer is simple and I am missing it. I have a 1.5tb Maxtor drive hooked up via fw800. I want to have 120gb of this as Mac OS extended journaled to back up my internal drive via Time Machine. I want the other 1.38tb to be in FAT32 so I can share files between my windows and mac machines. I keep all of my external storage except for the backup partition in FAT32. I have never had an issue until I upgrades to Leopard and now when I click on the larger partition I only have the option for the 4 mac formats-- FAT32 is not available. I can format the entire 1.5tb to FAT32 but once I try and partition it only mac formats are available. I forgot to mention I just did the upgrade to 10.5.1 and the issue is still present.
How do I format the smaller partition as mac os extended journaled and the larger as FAT32? Any help is appreciated.
Thanks so much,
Patrick
PS. I did a search but did not find anything.

It may depend on the type of partition table scheme you are using (see bottom of page in disk utility for that says Apple Partition Map/APM, GUID Partition table/GPT or Master Boot Record/MBR partition map).
MS-Windows can read MBR scheme only (64 bit MS-Windows supports GPT, according to MS). If you have Apple Partition Map, your disk won't be usable on Windows. I suspect you have APM partition table and hence the disk utility is not giving the option for FAT32 format, since you can't use it under MS-Windows.
On the Mac side, all 3 schemes are readable (for bootability, you'll need APM on PPC Macs, GPT for Intel Macs). Time Machine doesn't need a bootable disk, but I'd suggest APM/GPT if you are using PPC/Intel macs respectively (but I'd think either will work for Time Machine, if you have a mix of Macs).
But here's the catch - Apple says Time Machine won't work with drives with MBR partition map (even though Macs are MBR-aware), so the issue for you is Time Machine's ability to use MBR drives. http://docs.info.apple.com/article.html?artnum=306932
I suspect unless you are on an Intel Macs (OS X) and use only 64 bit MS-Windows (using GPT)/Itanium, using the same disk for TM and FAT32 sharing between Mac and Win worlds is not possible. Not the desirable answer.
If you do want to experiment, make a temporary setup and try it out on both Mac side and Windows side first (on all your machines), before making a "production" system. You can select the DISK (first line on Disk Utility for that disk, not second line) and click on Options at the left bottom (it might have to be erased first) and then select the type of partition scheme. Note formats like HFS+/FAT32 are a level lower in the hierarchy than partition map/table.
Let us know what you find out/decide?

I have an external Time Machine drive that I want to reformat. I can't remember the password. How can I do this. Disk Utility won't let me. Thanks.

I have an iMac that had drive problems last winter. Took the iMac to the Apple Store and they reinstalled everything and now it works again. Only thing is that my external Time Machine drive is screwed up now. Its 1.5 TB.
I had the Time Machine drive partioned into two parts. One partion was for an emergency bootup using carbon copy cloner. That partion I can open and mounts on my desktop. The other partion was Time Machine. It once upon a time opened and mounted without a password.
It requests a password to unlock even though I never had it password protected before the iMac drive problems. And so now it won't mount the drive.
I can go to Disk Utilities and I can see Time Machine with both partions. The Carbon Copy partion is mounted. The Time Machine partion is not mounted. For this reason I can't select it and erase it.
What the heck am I supposed ot do now to erase it and start over. Any help would be appreciated. I really don't want to go and buy another drive.

Triple-click anywhere in the line below to select it:
{ diskutil list; echo; diskutil cs list; } | open -f -a TextEdit
Copy the selected text to the Clipboard (command-C).
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V).
A TextEdit window will open with the output of the command. Post the contents of that window, if any — the text, please, not a screenshot. The title of the window doesn't matter, and you don't need to post that.
If any personal information appears in the output, anonymize before posting, but don’t remove the context.

Disk utility won't let me erase my hard drive

I'm giving my old PowerBook to a family member and want to erase the HD and reinstall 10.5.4 fresh. I opened Disk Utility and selected Erase and the drive bu the Erase... button is not available (transparent). How do I do this?

Disk Utility won't let me select "Repair" button - help!

I'm trying to upgrade from 10.3.9 to 10.4. When I run Installation, it fails and gives me a message that I need to repair my hard drive. So I restarted from the DVD, selected Disk Utility, clicked on my hard drive and was able to click on Verify. When it got done, it said the disk needed repairs. But the Repair button is grayed out. Any suggestions on either the trouble with the install or why I can't select Repair?
Thanks.

Usually, being able to select the internal HD and click on Verify but not Repair indicates one is actually booted up from the internal HD rather than the optical drive. Which drive is shown at the top of the Disk Utility list on the left?
What 10.4 version (e.g., 10.4.8) is shown on your retail black label Tiger 10.4 Install disc?
You can also try repairing the drive using the file system check fsck utility in single user mode, as described in Using Disk Utility and fsck.
When making disk repairs, repeat the repair until the utility reports no problems found or until it reports being unable to make further repairs. It's possible for one disk directory problem to mask another.

Disk Utility won't let me repair disk

Hello Mac helpers,
When I run Disk Utility on my hard disk it reports: "First Aid Failed.
The Underlying Task Reported Failure on Exit."
Also:"1 HFS Volume Checked
Volume Needs Repair."
However the "Repair Disk" button does not illuminate so I cannot repair the disk as instructed.
Any and all suggestions welcome.
Thank you in advance for your assistance.

You will need to contact Apple if you no longer have the recovery disks that came with your MacBook. They will probably charge you for a replacement. Thanks for the .

Disk utility won't let me resize Time Machine partition

My Time Machine is a 400GB partition of a 1 TB external HD. There is another 600GB partition that is empty. In Disk Utility I was expecting a dot/divider between the two partitions so that I could resize them. It is not there and and when I select the TimeMachine partition is says 'This Partition will not be modified'.
Can I re-size ( increase) the TimeMachine partition? or do I have to delete and recreate?
My Timemachine backs up a 500MB HD in my iMac (40% full) and a 500 MB external HD for iTunes (22% full) (including AppleTV content).
I was thinking of making the TimeMachine partition 1TB? does that make sense?

what do you mean? what's not there? the divider? that can't be. please explain exactly what you are seeing in disk utility. first, you can only increase the TM partition using DU if it's the upper partition when viewed in DU. if it's the lower one then you can not increase it with disk utility. secondly, the other partition should be deleted, not just empty. you can delete it using the minus sign in the partition tab in DU. then grab the lower right end of the TM partition and drag it all the way down to cover the free space left by the former 600GB partition. then click "apply".
and and when I select the TimeMachine partition is says 'This Partition will not be modified'.

I want to make a .iso to backup my computer - disk utility won't let me

Just like the title says - disk utility refuses to back up my computer as a disk image. I've tried the hard disk, and the Mac HD volume, but it both cases disk utility tells me "resource busy"...***? What should I do to get around this problem? I thought it might be errors on my hard disk or hd volume, but disk utility seems impotent to take any action saying:
"Verifying volume “Macintosh HD”
Checking HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Checking multi-linked files.
Checking Catalog hierarchy.
Checking Extended Attributes file.
Checking volume bitmap.
Checking volume information.
Volume Header needs minor repair
The volume Macintosh HD needs to be repaired.
Error: The underlying task reported failure on exit
1 HFS volume checked
Volume needs repair
Are these processes related? Are errors on my HD volume causing disk utility to not backup my computer?
Any and all help is appreciated!
Vincenso

Vincenso, you need to repair that error first, but it can't be done while booted from it.
"Try Disk Utility
1. Insert the Tiger Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then Safe Boot , (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it finishes.
And where are you trying to put the ISO?

Disk Utility won't let me delete the partition disk

can some body help me for that ...?

What specific steps have you tried so far. Is your disk full (with only a few GB left on it)? When you go to Disk Utility, are you selecting your drive device (above the listed volumes) or are you selecting your boot volume or other volumes in an attempt to split them up?

IMac disk utility not reading any FAT32/NTFS related partitions/CD/flash drives

Hi everyone!
I'm trying to access my drives and later on install bootcamp and windows on my iMac. At moment I can only start the iMac in safe mode (long story, if interested check out iMac 27" (late 2009), freezing - List of solutions tried). Any steps taken so far to read and format other drives has been in Safe Mode.
Problems:
- any formats except Mac OS X extended gets greyed out in Disk Utility.
- Not able to read/mount flash drives, external drives or CD's with any other formats.
Solutions tried:
- Tried to format using OSX on current iMac, MBP and PC and no change or luck.
- Tried on other machines and it works great. So it's related to my iMac.
- Disk Utility try to Mount drive/partition - getting error "The disk "BOOTCAMP" could not be mounted"
- Installed Paragon NTFS but no difference.
- Disk Utility no disk error reported
Searched on internet and forums for a solution w/o any luck. Haven't found anyone with similar problems or I'm using wrong keywords. Haven't found any Knowledge Base about other formats is disabled in Safe Mode state so it can't be that either. Below is a picture that shows any other partitions than mac is greyed out.
Any suggestions or anyone encounter with this wierd behavior?
