Viewing disk partitions made using Disk Utility in Windows

So, I took a USB external hard drive and partitioned it into two volumes using Disk Utility. I made sure to format them in MS-DOS format so they are FAT16 and can be recognized by Windows. I then took the hard drive and plugged it into my Windows computer. The first partition showed up just fine in my F: drive, but I'm not sure where the second partition is. When I plug it into my Mac, both volumes appear on my Desktop, but only the first one shows up in the Computer folder of my Windows computer.
Any help would be appreciated.

What does it look like in Windows Disk Management?
Click Start (if you're on XP then click run) and type "diskmgmt.msc" without the quotes (on XP click OK, anything after XP click on the program), then in the bottom window (where it says Disk 0 Basic disk etc) find your external drive, what do the partitions look like?
It might be that windows isn't mounting that partition for some reason.

  • Hi Group: I think my "Macintosh H.D." disappeared off my desk top when I cloned the drive in setting up ext drive. The space at top rt corner went blank, the drive shows in disk utility, startup window, in the finder it shows up as "my Mac Pro'Help"

    Hi Group:
    In trying to set up an ext Drive for different purpose, I cloned my Macintosh H.D. drive and saved on another drive. Then I cloned the data on the Ext, used my orig. DVD to install sy on it, 4 attempts before it would accept the install. Did a reboot to confirm install no luck, and noticed that the space at top rt of D/T blank, the 2nd,3rd,& 4th bay Drives appeared below a blank space. My Mac H.D. appears in startup window & D/U but in finder Pref it is listed as " my name Mac Pro". The desk top has stayed the same, I can use startup to S/U  in all drives with a Sy, including Macintosh H. D. altho no icon or other clue that I am booted in it.
    During all my attempts with cloning and saving etc I think I made it invisible. I am not comfortable to try Terminal to find out. I will be totally thankful for all suggestions.
    I am using a Mac Pro (2008) with OS 10.6.8
    The external drive is on Firewire
    I used Disk Utility to set up drive
    I used  CCC to clone
    Thanks Funoptics

    go to finder preferences then side bar. make sure hard disk is ticked.

  • Known problem with Disk Utility formatting Windows NT drive ?

    I have had a strange problem while formatting a newly purchased Iomega USB (Seagate) with version 11.1 (252.4) of Disk Utility (OS 10.5.8). The drive was NTSF and I wanted Mac OS extended. The first attempt failed, unfortunately I didn't note the exact message. I tried again and this time D.U. was stuck on on a wait progress bar with message "not a multiple of 4". Disk Warrior reported disk too severly damaged. Only Drive Genius could properly format the drive. Anyone knows what happened?

    I'm not sure what caused the problem you observed, but did you first change the partition scheme to a Mac-friendly one before you tried to do the reformat?
    Thanks.
    Well, no I didn't and I simply applied "erase to Mac OS extended". Maybe there is a change from earlier versions of D.U. So far and as far as I am aware, D.U. would erase a DOS disk and by default choose the Apple partition scheme. But this default setting could have been changed to GUID with the Intel Macs, or even to DOS if the drive is DOS. This option is hidden in further options in the partition settings along with the DOS partition scheme and unless you decide to partition the drive and not just erase it, it is not visible. As a matter of facts, Drive Genius offers the choice between Mac OS and GUID as you erase the disk.
    So this could be the culprit, if for instance D.U. erased to Mac OS extended but kept the DOS partition scheme. It seems unlikely though that the developers didn't take that error possibility into account to include a warning of some sort... but that's what I wanted to make sure.

  • Use Runtime Util in Windows 98

    I want to launch an external application via my Java program. I use following codes in Windows NT and it works fine.
    String command = "cmd /c type sample.txt > copyOfSample.txt";
    Runtime.getRuntime.exec(command);
    When I move to Windows 98, I tried the same code. It doesn't work. Then I tried command = "command /c type sample.txt > copyOfSample.txt". It still doesn't work. If I typed the same command at dos prompt, it works fine.
    Can any one help me out? Thanks a lot.

    The example I use is a simple example. But the real case I have is using a special compiler to compile a file and then write the compile result into another file.
    The file to be compile is dynamically decided. How to put this kind of command into a batch file? Could you give an example?
    "javac c:\dir\test.java > c:\dir\result"
    Thanks.

  • Using OCOPY utility in Windows

    Dear Sirs:
    I have setup a Oracle 10G RAC in VMware where the two guest operating systems are Windows 2003.
    The VOTING DISK, DATABASE DISK, and the OCR DISK are as /device/Hardisk1/Partition1, /device/Harddisk2/Partition1, and /device/Harddisk3/Partition1
    respectively. These are all virtual devices.
    Now when I query the V$Controlfile view for locations I am getting result as:
    NAME
    +DATA/rac/controlfile/Controlfile123456.7889
    +DATA/rac/controlfile/Controlfile16361.737982
    If I am using " C:> OCOPY \\.\PHYSICALDRIVE2 C:\ " the whole ASM drive (that is disk2) is getting copied.
    If I mention " C:> OCOPY \\.\+DATA\rac\controlfile\Controlfile123456.7889 C:\" the utility says that input file not found. I am making lot of permutations
    and combinations for the input file path such as back slash to front slash, getting rid of the + sign before DATA etc etc, but no useful result.
    I know that using OCOPY for backup is never the best practice. RMAN should be used. But my problem is that I want to learn OCOPY learn the concepts of
    ASM, RAC.
    Please let me know that if I want to take manual backup of specific files (data file, control file, log file) then how should I use OCOPY?
    Even if I want to use RMAN for specific files only then what is the command.
    I am extremely new to RAC. Thanks in advance
    Best regards,
    Caesar

    hi User, Welcome to forum.
    DBMS_FILE_TRANSFER copies files on the same Oracle server or between two Oracle servers. It uses directory objects to specify the source and destination directories and, because directory objects support ASM pathnames, so does DBMS_FILE_TRANSFER. This makes it an easy way to move files to and from ASM storage from a regular filesystem.
    for more information, refer the link: how to copy?

  • Trying to view Ipad file system using a computer running Windows 7?

  • Snow Leopard Installer does not recognize Hard drive in disk utility.

    I first at the suggestion of apple technicians because of other problems erased and partitioned hard drive. Now when I go to reinstall Snow Leopard it does not recognize the Macintosh Hard Drive, not even in disk utility. Any help will be greatly appreciate.

    To make sure we understand everything correctly, you are saying that when you start up from the Snow Leopard DVD & run its copy of Disk Utility from the Utilities menu, it shows only the DVD installer disc itself in the list on the left of Disk Utility's window? There is nothing else there?
    Also, what are you booted from when you try to make an image of the installer DVD, the DVD itself or something else? Are you using Disk Utility or something else to make the image?
    This seems very weird for sure. If you were running from some hard disk copy of the OS, I would suspect that its copy of Disk Utility or some OS support file was corrupted, but if you are doing this from the DVD that is extremely unlikely unless the DVD itself is physically damaged.
    Apart from that, pretty much the only thing left is a damaged hard drive or other hardware failure in your Mac.

  • Disk Utility Error "no valid packages"

    Hi,
    I have a PowerBook G4 with 1GB RAM.
    I've noticed a significant system slowdown lately. Programs take longer to open and respond, and it's rather annoying. I came to the forums to seek some remedy, and tried to run a Disk Utility to check that everything there is at least okay. But when I click on verify permissions, I get an error that says "no valid packages." Does anyone know what this means and how to fix it (if it needs fixing; I'm assuming this isn't a good thing, whatever it is!).
    Thanks.
    Lori

    Hi librarygirl and Welcome to the Discussions!
    Mac OS X 10.3, 10.4: Disk Utility shows a "No Valid Packages" alert
    Disk Utility can't verify or repair permissions on the Mac OS X 10.3 or 10.4 volume if the "BaseSystem.pkg" file is not in /Library/Receipts.
    This alert appears when you try to repair permissions with Disk Utility:
    "First Aid failed
    "Disk Utility stopped repairing permissions on '(volume name)' because the following error was encountered: No valid packages"
    In the Disk Utility text window, this message appears in red text:
    "Error: No valid packages (-9997)"
    This happens when the BaseSystem.pkg file is not in /Library/Receipts.
    Solution
    If you've moved this file, move it back to /Library/Receipts. You shouldn't normally remove any files from /Library/Receipts.
    If the file has been deleted, replace it by copying it from a different computer that uses Mac OS X 10.3 or 10.4, or by reinstalling Mac OS X 10.3/10.4 from an installation disc.
    "Reinstall" means you can install 10.3 or 10.4 from a disc, if it's the same version of 10.3/10.4 (such as 10.3.3 on both the installation disc and computer). If the version of 10.3/10.4 on the computer is newer than what's on the install disc, then use the install disc to perform an Archive and Install installation instead, then update to a later version of Mac OS X.

  • Disk Utility hangs ("not responding") when attempting to Repair Disk on Time Capsule sparsebundle.  Help.

    I am trying to improve the performance of my Time Machine backup and retrievals via my 2nd Gen. Time Capsule from my iMac Core 2 Duo hard drive with SL 10.6.8.  The incremental backups generally take 20 - 40 minutes each hour generally with fewer than 100 MB of data being backed up.  I have read through numerous threads on these forums about Time Capsule and Time Machine issues as well as the very helpful Pondini site (http://web.me.com/pondini/Time_Machine/Home.html) and have tried many other suggestions (listed below), but have been unable to attempt a Disk Utility repair disk on the Time Capsule sparsebundle file.
    After locating the sparsebundle 'file' in the finder under Shared/TC/Data, I am only sometimes able to drag the sparsebundle into the Disk Utility volumes and disk window.  About fifty percent of the time, Disk Utility hangs when attempting to drag in the sparsebundle.  If I am able to get it listed and click on "repair disk", then the beach ball begins to spin and nothing happens.  This occurs whether or not I first use AirPort Utility to "Disconnect All Users" from the Time Capsule.  I have given it over one hour to attempt the repair disk, but nothing happens, i.e., not a single message shows up in the detail window.  The beach ball just spins, and Disk Utility shows up in red as "not responding" under the Force Quit menu.
    Also note that on my new Macbook Air, Time Machine runs quite quickly via this same Time Capsule from my new Macbook Air using OS X Lion (which seems to indicate that the Time Capsule drive itself is OK).
    I would appreciate any tips on getting Disk Utility to run "repair disk" on my sparsebundle, as I seem to have exhausted most other options (see below) for improving Time Capsule performance -- aside of course, from wiping the Time Capsule clean and starting all over.... (which I really don't want to do, and from what I've read, has not helped some people who've tried this anyway).
    Many thanks!
    Although I would like to focus this thread on the Disk Utility / sparsebundle "Repair Disk" problem, I should mention that I have tried the following other things:
    1.  Repaired disk permissions on my hard drive
    2.  Used Disk Utility to run "repair disk" on my hard drive after starting up from a SuperDuper external backup
    3.  Run DiskWarrior on my hard drive, again, from a separate startup disk
    4.  Did the "full reset of Time Machine", a la Pondini Troubleshooting #A4
    5.  Changed my computer and Time Capsule names to simple short names with only alphanumeric characters and no spaces
    6.  Ensured that my Time Capsule is being accessed only via ethernet
    7.  Relaunched the finder
    8.  And finally, attempting to use Disk Utility to repair the sparsebundle - thus the nature of this post

    OK, no takers out there, but I answered my own question (sort of).
    The answer is that even though Disk Utility shows up as "not responding" under the Force Quit menu and appears to hang, it is actually still working.  A bit of patience shows that after about an hour, my Disk Utility was able to show the 1.44 TB Time Machine sparsebundle from Time Capsule in the disk window on the left hand side.  Once this appeared, I was able to click on "Repair Disk" (note that prior to doing this, I had to "Disconnect All Users" from my Time Capsule using the Airport Utility program; otherwise you will get a "could not unmount disk" error).  Again, the Repair Disk function appeared to hang Disk Utility as it showed up as "not responding" under the Force Quit menu.  However, after about 8 hours, Disk Utility did run the entire Repair Disk protocol on the sparsebundle.  The results DO NOT show up in the Disk Utility details window - so even if you are patient enough to let it complete, you will not see anything and may think that nothing happened.  However, you can find the familiar results of the Repair Disk function by looking on Console - find the "DiskUtility.log" under Files: ˜/Library/Logs.
    Unfortunately, I was hoping to find a problem that would have been subsequently repaired which would result in dramatically increased Time Capsule speed, but this was not the case.  Disk Utility showed everything to be "OK" and I am stuck with a very slow Time Capsule....
    (And of note, my new Macbook Air (OS Lion) Time Machine functions blazingly fast on both backup and retrieval to and from the very same Time Capsule - even though, these are occuring wirelessly via AirPort -- granted the size of this sparsebundle is an order of magnitude smaller at this point, i.e., only 10 GB right now)
    Would still be happy to hear of any similar experiences or tips on getting Time Capsule to work more quickly.

  • What is Disk Utility parameter : 'Owners Enabled' about?

    There is a parameter in the Disk Utility dialogue window , bottom left corner that says (on mine) Owners Enabled: No.  What does that signify and how, where or why is it set?

    That parameter can be set manually in the getInfo window of the drive itself (in Finder, not inside Disk Utility). See if this adds any insight:

  • Why  does .dmg creation fail in Disk Utility app ?

    Want to duplicate a DVD with a VIDEO_TS folder containing various video files. Inserted the DVD, started Disk Utility, selected the mounted DVD in the Disk Utility left window, and chose File>New>Disk Image from (the mounted DVD name). In the Convert Image panel, I chose a name, selected "read-only" and hit Save. The Disk Utility Progress panel states a .dmg is being created and shows a progress bar. Then it displays the following message: "Unable to create 'disk2.dmg' - No such file or directory" I'm pretty sure the DVD I wish to copy was burned on a Windows PC.
    Thoughts?

    Tom --
    I'm sorry to be the bearer of bad news, but apparently files have been deleted from your Receipts folders.
    See this article for more info:
    http://docs.info.apple.com/article.html?artnum=25704
    I hope your BaseSystem.pkg file has just been moved, and not deleted.
    But if it's gone, there are instructions in that article to fix the problem.

  • Strange disk showing in Disk Utility

    After doing several updates recently on my MacBook Air, decided to run a Disk Permissions Repair. Upon opening Disk Utility, I see my HD, then a grey horizontal line, and under that I see: decryptedFile.dmg then an icon of Flash Player under that. Seemed rather strange to see this in Disk Utility. Why is it showing up? Do I need to to be concerned? How do I get rid of it?

    The automatic Flash update service downloaded it. If you've installed the update, choose Go to Folder from the Finder's Go menu, provide the path at the bottom of the Disk Utility's window without the file's name, and delete it from there.

    I used a partitioned HDD for time machine, using a partition already containing other data files. I am now no longer able to view that partition in Finder. Disk Utility shows it in grey and "not mounted". Any suggestions of how to access the files? Does using time machine mean that that partition is no longer able to be used as it used to be?

    Yes, sharing a TM disk is a bad idea, and disks are cheap enough so that you don't need to.

  • Resized partition using Disk Utility and now Windows 7 will not boot

    Hi,
    Hopefully someone can help me!!
    I had previously used Boot Camp to install Windows 7. However, I later realised I had not given myself anywhere near enough disk space as I started using Windows for things I hadn't originally planned on using it for.
    Anyway, long story short, to solve the problem I uninstalled some applications on my Mac OSX and used Disk Utility to decrease the size of my Mac partition. My plan was then to reboot to Windows and use a Windows application to increase the size of the Windows partition. However - I coudln't even get that far.
    Upon decreasing the size of my Mac partition (succesfully) I restarted my Mac in order to boot to Windows. However, I was greeted with a message along the lines of "unable to boot to Windows please insert boot disk and press any key" (I can't remember the exact message).
    I was wondering if anyone knows of any way to restore my Windows partition, retaining all of my previously saved files on my Windows disk. It's probably a long shot, but the thought of losing everything I have been working on for the last few months is a sickening one.
    What does give me a bit of hope is that, if I click Boot Camp it seems to recognise that Windows 7 is installed as the option that appears is to uninstall it.
    Furthermore, if I view partitions in Disk Utility, a "DISK0S4" is listed. However, it's only at 20gb - if this WAS my BootCamp partition previously, it was originally at something around 60gb (I think - either way, definitely bigger than 20gb!).
    On top of this, my current Macintosh HD parition is at 260gb and with the DISK0S4 partition at 20.21gb, there seems to be some space missing... I'm hoping this is the files I've been working on over the last few months!
    Anyway, I've done some searching on the net and it *seems* that GPT fdisk *might* be my savour. I've downloaded it but have no idea how to use it and don't plan on playing about with it as I could no doubt do some real damage. If it is likely to solve my problem however, I'm certainly more than capable of being walked through what I need to do.
    Please help!

    Hi Christopher,
    I also have problems with Windows rebooting after partition resize trying to reduce Mac side and increase Windows side. I do not see the BootCamp partition labelled as such while running disk utility. The Windows partition shows up when I boot up while pressing the ALT key. However, when I try to run Windows, it says " error loading operatig system".
    I also followed instruction and went through to run gdisk successfully. Results towards the end.
    What can be done? Windows still does not boot and It shows ? Suspicious MBR at sector 0.
