Jump drive vs. disk image for secure data, which is better?

I want to store all my financial files somewhere securely....encrypted and password protected. It seems my choices are either a jump drive or disk image. If I use the disk image on my Pro, I'll have to be able to back it up to an external drive for storage at another location. Is one method better than the other?

Well, I personally would go with a hardware encryption method over a software method. I have encrypted USB memory sticks, and they are not cheap, but they work seemlessly between my Mac and my Windows computers. I have used hardware encrypted external hard drives, and they have worked just as easily for me. The beauty there is that you don't need to install any software on a computer to use them. The drawback is that when they fail, you have much less hope of recovering your data, but since this is critical information, you are keeping it backed up somewhere (securely), so that is less of a concern.
There are plenty of good software choices as well, some of which are even free.
Back to your original question, flash memory or spinning disk? Both have a limited lifetime, and both will fail. Each time you write to flash memory you shorten its life a very little bit, so if this is information that will be updated quite often, a spinning disk might be a better choice. Also, capacity for your dollar will be lower cost for a spinning disk. I believe that Google has some interesting stats on spinning disk life spans, and considering the amount of data they have to deal with, they would be a good source for they type of statistic...

  • Hard Drive and Disk Image not mounting

    Hey everyone,
    I'm running a G5 Dual 2Ghz. with OSX 10.5.8 I'm having problems with a back up hard drive. It is an external Western Digital My Book 1.5TB SATA drive. After using it for a few months, it suddenly did not mount anymore.
    *1) It also would not appear in Disk Utility.*
    a) Disk Warrior couldn't find the drive (I think because it's formatted with FAT32)
    *2) I then took the drive out of the enclosure and put it in the spare bay in the G5.*
    a) It didn't mount
    b) It did show up in Disk Utility
    c) In Disk Utility it wouldn't give me the option to Repair Disk Permissions or Repair Disk
    d) In Disk Utility is says under Partition Scheme: Unformatted
    e) In Disk Utility I don't have the option to mount/eject only gives me the "info" option
    f) Tech Tool did find the drive and it passed all tests
    g) Disk Warrior still did not find the drive
    h) TestDisk finds the drive, but does not find any partitions
    *3) I then created a disk image of the drive in Disk Utility onto an external hard drive. The image comes back at 320GB, which seems to be about right I think.*
    a) The disk image would not mount with Disk Image Mounter. It would say there is an Unrecognized File System
    b) In Disk Utility - I don't have the option to Repair Disk Permissions
    c) In Disk Utility - When trying to Repair Disk - I get the error: Repairing Disk failed with error Unrecognized FileSystem
    d) In Disk Utility - If I click Open - The Log file says:

    +Image of "disk0.dmg" attached successfully+
    +Mount of "disk0.dmg" succeeded+
    -But it is no where to be found
    e) Disk Warrior can not find the Disk Image
    f) I took the new external drive with the Disk Image to 3 other mac computers but the image would not mount
    *4. Other things I've tried when opening the Disk Image for the new external drive.*
    a) in Terminal - hdiutil attach -nomount "volumes/untitled/disk0.dmg"

    c) Deleting files System/Library/Extensions.kextcache
    System/Library/Caches/com.apple.kernalcaches
    ALL UNSUCCESSFUL
    I'm running very low on ideas. I know I could just erase the drive and reformat it, but the files on it are very important and must be recovered.
    Any help or suggestions would be very helpful. I will not have time until after the weekend to try more things. Thanks in advance if you do not hear back from me until after this weekend.

    Yes, it will. But if DU says the disk is unformatted then it is also not accessible. If you have files you don't wish to lose then you will need to try recovery software:
    Basics of File Recovery
    General File Recovery
    If you stop using the drive it's possible to recover deleted files that have not been overwritten by using recovery software such as Data Rescue II, File Salvage or TechTool Pro. Each of the preceding come on bootable CDs to enable usage without risk of writing more data to the hard drive.
    The longer the hard drive remains in use and data are written to it, the greater the risk your deleted files will be overwritten.
    Also visit The XLab FAQs and read the FAQ on Data Recovery.

    Well it should work if you have loaded the image at the right place in the Tab Document. Please verify the same.
    What I did to check this :-
    Go to Tab Document -> follow the tree structure Document -> Picture -> Full Size.
    The Right click on Full Size ->create -> Document -> Import. And I imported a picture form my desktop. I did the same for Thumbnail. I can see the image in the top right corner of the screen in TX COMMPR01.

  • I need the Log Report for the Data which i am uploading from SAP R/3.

    Hi All,
    I am BI 7.0 Platform with Support Patch 20.
    I need the Log Report for the Data which i am uploading from SAP R/3.
    I extract the DATA from R/3 into BI 7.0 DSO where I am mapping the GL Accounts with the FS Item.   In the Transformation i have return a routine on the FS Item InfObject . I am checking the Gl code into Z table for the FS Item .
    I capture the FS item from the Z table then update this FS item to Infobject FS item.
    Now i  need to stop the Data upload if i do not find the GL code in the Z table, and generate report for all GL code for which the FS item is not maintained in the Z table.
    Please suggest.
    Regards
    nilesh

    Hi.
    Add a field that you will use to identify if the GL account of the record was found in the Z table or not. Fx, create ZFOUND with length 1 and no text.
    In your routine, when you do the lookup, populate ZFOUND with X when you found a match (sy-subrc = 0) and leave it blank if you don't find a match. Now create a report filtering on ZFOUND = <blank> and output the GL accounts. Those will be the ones not existing in the Z table, but coming in from your transactions.
    Regards

  • When shooting source images for "HDR Pro", is it better to using 16 bit TIFF rather than 8 bit JPEG?

    When shooting source images for "HDR Pro", is it better to using 16bit TIFF rather than 8 bit JPEG?

    Yes, you will bracket the exposure.
    Take as many shots as you need. Take a normal shot, underexpose twice or even three times and then overexpose twice or three times.
    That's how the camera will register all teh details in the image - in the highlights, in the shadows and in the midtones. When you bracket, remember to change shutter speed (if you shoot manual, that's what I do), not the aperture because you will end up with different depth of field.

  • Using disk image to put data into a "stick" for use by PC & Mac

    I am trying to find a quick way to transfer a master file (almost 1gb) onto a series of "sticks" for circulation to colleagues.
    I thought that if I made a disk image that would be OK. It works for Macs but PCs say they cannot find a progamme to open the stick. They recognise it as a FAT disk.
    PLEASE help me save hours of time.
    Colin

    I'm guessing the reason you want to 'bundle' up the files is to avoid the slower copy speed of lots of small files? If that or the desire to compress the data is you reason for using a disk image, zip them instead. Windows and most Macs will be able to open the zip file without additional software and any Macs that are running Jaguar or older OS versions will almost certainly have Stuffit Expander which can also decompress zip files.

  • How do i find or replace the missing disk image for my HD

    How do i find or replace the missing disk image? for my HD ........as it is missing when i try to back up with time machine, 
    i asked for assistance the other day with time machine
    now i have worked out this is the reason i can not back up with TM, due to no disk image in my portable hard drive
    I saw a post on youtube where it explains you can copy a your HD disk imag from your time machine back ups enabeling, time machine to back up
    But i can not find where the TM Back up driver is situated in my TM Back up's
    Some advice would be greatly appreceate   as i am rather new to Mackintosh 
    Thank you
    Aiden

    Hi again.
    Just re-reading your first post, I wonder if you're confusing a disk image backup with Time Machine?
    It's certainly possible to create a disc image of your Macintosh HD and copy it to an external drive.
    However, as a backup that method has a drawback; you can't boot from a disc image directly. It needs to be mounted on a bootable system before it can be used. So it's not really much use if the internal HD fails, at least as far as allowing you to carry on working while the repair is carried out.
    Much better (and simpler) is to clone the whole drive to the external using CarbonCopyCloner or SuperDuper (there are plenty of others, but those appear to be the most popular).
    That will give you a bootable backup which can be kept up to date by incremental backups using the same applications.
    In the event of total internal HD failure all you need to do is replace the drive then boot from the clone and reverse clone to the internal to get up and running again.
    Many of us use both a bootable clone and Time Machine (on seperate drives) as each has it's different uses.

  • Creating Disk Images for viewing on a PC

    I created a data dvd of information for work on my iMac by dragging the folders that I needed onto the DVD.  I then burned it in my super drive.  I put the completed DVD into a pc and navigated through the files.
    I created an image file (dmg and cdr) of the DVD on my iMac for future use in case someone else wanted a copy of the information.
    When I burn the dmg or cdr image to a DVD, I can navigate through it with my iMac without any problems but when I put DVD into a PC, the PC says that it is a blank disk.
    I guess my question is, how do I create an image so that I can burn it and use it on either a mac or a pc?

    I created the image from a disk.  I put the DVD I wanted to image in the super drive, opened Disk Utility, selected the DVD from the left side of the Disk Utility window.  I then went to the menu:  File - New - Disk Image From <Name of the DVD>.  I tried to use different image formats (Read/Write, DVD/CD Master).
    When I went to copy the dmg file, I selected it and then Burned it.  It is readable in my iMac but not on a PC.

  • How do I create a disk image for windows 7, using a windows computer for USB bootcamp for mac?

    Hi There, I have just bought a new 2013 iMac.
    Spec: 3.4 GHz intel core i5, 16GB 1600 MHz DDR3 Memory , NVIDIA GeForce GTX 775M 2048 MB Graphics with OS X 10.9.4.
    How can I create a 'disk image' from a windows 7 professional 64bit installation DVD using a windows laptop with windows 7 Operating system on? I want to transfer this 'disk image' (ISO?) to a USB ready for installing windows onto my 2013 iMac using bootcamp?  I want to use bootcamp from a USB as I have no disk drive for the installation DVD on my iMac. I hope all this is clear.
    Thank you. Joe

    Yes, that's correct, at least not directly. You can create a blank disk image, copy the file to the mounted disk image, then burn the image to a CD/DVD.
    Open Disk Utility and select Blank Disk Image from the New menu. Provide a name, Save location, and select the image size from the drop down menu. Leave Encryptions at None and Format as read/write. Click on the Create button.
    After the image file appears the "removable" disk should be automatically mounted. If not double-click on it to mount it. A "removable" disk icon will appear. Drag the file you want to place on the disk image to the "removable" disk icon. The eject the "removable" disk icon. Now select the disk image file in the DU left side list and click on the Burn icon in the DU toolbar. Be sure to have a blank disc ready.
    The above is actually the "long" way to do this. A much easier way is to simply insert a blank CD or DVD into the optical drive. The Finder will pop up a dialog asking what to do. Select the option to mount on the Desktop. You will now see a disc icon on the Desktop. Drag the file you want to burn to the CD/DVD, right-click or CTRL-click on the disc icon and select Burn from the contextual menu.

  • External Drives, CDs & Disk Images Won't Mount

    I am having some weird issues with my G5. I recently did a fresh install of Leopard on a brand new hard drive and everything was running smoothly. I copied a bunch of settings from another drive to keep my information intact on the new install and I didn't notice any issues. I have now started to notice that after about a day of leaving the G5 on, it no longer mounts disk images, CDs or external hard drives OR if it does in fact mount them, it takes FOREVER to do so. This also causes Disk Utility and System Profiler to crash or take a long time to start.
    I don't know if this helps at all, but two new hardware additions to the machine were an internal bluetooth adapter (for use with the new Magic Mouse) and more memory. Both have been working correctly so I don't know that either is the cause of this problem.
    I've tried a bunch of random things to see if I can get something to work again - fixing permissions, verifying disks, etc., but the only thing that really works is a restart. Everything stops working again about a day after the restart though.
    Has anyone else encountered this sort of problem, and if so, do you have any suggestions for how to fix it? Any help would be appreciated!

    So I think I may have something to show from Console regarding an external drive that took forever to attach:

  • Using disk images for learning games?

    Hello, I've 2 g3 imacs running 9.2.2, and they are for the grandkids to use learning games on.
    The kids are very hard on the software disks. When I found out about disk images I made them up, now to install them properly. The games are installed, but where to store the disk images? The desk top icons for the games will work after the disk images have been double clicked and the mounted disk image appears on the desktop, but when the imacs are turned off the mounted disk image is lost. How or where does one put the disk images in a safe place so the kids don't get at them, and the disks are mounted every time, without actually starting, when the Mac is started? Start up menu?
    I'm planning on multiple accounts with them having a standard account with game privileges so they don't mess the whole thing up. If their accounts get too messed up for me to repair I figured on maybe deleting the account and opening up a new one? Any Ideas are very welcome.
    Thank you,
    EZ

    Hi, EZ -
    You're quite welcome.
    I had a thought with regard to the disk image files. Are they in a .smi format, or are they in a .img format?
    The .img format requires the assistance of the Disk Copy utility in order to mount the image. This is the standard format generated by the user version of Disk Copy. It requires that Disk Copy be available to Finder to act as a helper app in order to mount the image.
    The .smi format does not - .smi stands for Self-Mounting Image. The user version of Disk Copy can not make this format; but I have seen a utility to convert .img format to .smi format. The slight advantage with this format is that Disk Copy does not need to be available to Finder.
    In both cases the default is to run a checksum verification before the image is finally mounted. The delay caused by this verification can be inconvenient - verification is intended to confirm the integrity of the image after it has been copied, transported, or downloaded, but is usually not necessary when the image resides on a hard drive.
    The checksum verification for .img file types can be removed. With the image not mounted, open Disk Copy. In Disk Copy's Preferences (Edit menu), uncheck the Verify Checksum item. Save the Preferences window. Then select Convert Image from the Image menu, navigate to the disk imge file from which you want to remove the verifiaction, select it and click the Open button. A new window will appear, similar to a Save As type window. Leave everything in that window untouched (unless you want to change the base name of the file - the extension .img should be left intact) and click the Save button. The image will be mounted, the original disk image file will be deleted, and a new disk image file created. Unfortunately creating the new image file takes quite a while since it is creating a new one, not actually modifying the old one - but it does get rid of the intrusion of the checksum verification requirement.
    I verified on my G4/500 running OS 9.1 that a .img file (one I had made from a game CD years ago) dropped into the Startup Items folder will be mounted automatically at the end of the startup sequence. I also tested with an alias to the .img file, and it, too, worked fine - the disk image was mounted automatically at the conclusion of the startup sequence.
    When you make the alias to the disk image file (the .img one), be sure you are placing it into the Startup Items folder, and not the Startup Items (disabled) folder.
    If you have the machine set to use Simple Finder (which removes Finder's keyboard commands and many menu options for Finder), that may interfere with items in the Startup Items folder being run at startup. Or, it may not - I have not checked that.
    *** Edit ***
    I have verified that the alias to a .img file will mount the disk image even when the machine is booted using Simple Finder.
    Another thought, related to Multiple Users - if you do decide to set up Multiple Users, and the disk images are of type .img, be sure to authorize Disk Copy for each of the accounts for which the disk images are to be mounted. If you have the disk image files in a .smi format, since Finder views that file type as being an application, you would need to authorize each of those disk image files for each account which is to have access to them.

  • Disk image for restore won't verify

    Hi - I'm preparing to send my G4 Pbook (10.4.11) for repair.
    It was recommended that I make a disk image of the HD "just in case".
    So I booted from the original install disc (10.3), launched Disk Util and made a new image on an external drive. Read only, not compressed. About 3 hours later I had a DI and decided to "verify" it. It would not. So I rebooted from the normal system and tried to mount the new DI. It would not and gave a message "the DMG is faulty and it may damage your hard drive if you mount it". So I trashed it, emptied the trash and used DU to erase that external drive in ready for the next try.
    DU Help files are short and pretty clear. What did I do wrong? Can someone please give me a procedure I can succeed with?
    TIA
    d2

    Don't make a disc image. You cannot boot from one and they can be finicky. They are not what you want. Instead you want to clone your hard drive to an external Firewire hard drive. It's done as follows:
    How to Clone Using Restore Option of Disk Utility
    1. Open Disk Utility from the Utilities folder.
    2. Select the destination volume from the left side list.
    3. Click on the Erase tab in the DU main window. Set the format type to Mac OS Extended (journaled, if available) and click on the Erase button. This step can be skipped if the destination has already been freshly erased.
    4. Click on the Restore tab in the DU main window.
    5. Select the destination volume from the left side list and drag it to the Destination entry field.
    6. Select the source volume from the left side list and drag it to the Source entry field.
    7. Double-check you got it right, then click on the Restore button.
    Destination means the drive to which you will restore or backup.
    Source means the drive you are restoring from or backing up.
