USB Flash Drive Erased after using on MBP?

I use a Kingston Data Traveler flash drive (256mb) on my Dell PC. I plugged it into my new MBP last night to print out 4 Word Documents. After trying to open them from the flash drive folder (and getting the same error message I get when trying to open a Word file from the desktop), I opened Word and opened the documents from the File menu in Word, printed, ejected my drive, and thought all was well.
Today, I inserted my Kingston into my Dell and was met with a message saying "This disk is not formatted." After trying to open docs in Word, the message read: "This disk is not formatted or has been formatted for a Macintosh."
When I tried to access my files on the MBP, the computer tells me "This disk could not be read."
The folks at AppleCare are blaming Word. I have no idea what to think. All I know is that this drive worked perfectly until I inserted it into the MPB. Has this happened to anyone else? What are my options for salvaging my data?
Thanks in advance...

Sounds like you accidently reformatted the drive HFS+, so the data may sadly be gone for good. If you didn't backup the files on the flash drive, say onto the Dell's HD, as well, then you should probably do so in future.

I tried to export photos from iMac to iPad using a USB flash drive. The photos are on the drive but when I plug it into the iPad, the iPad says the device requires too much power. Any ideas of what type of USB flash drive I should use?

You can transfer photos outside of iTunes. I do it all the time. THat said, i have a 50/50 success rate with them. I'd avoid sandisk and kingston, their bundled software triggers the 'too much power' warning.
I've had mixed luck with lexar, some work, some don't.
I did have good luck with an older 4 gig geek squad one.
Look for drives without software on them, without bright LED lights and I haven't gotten any larger than 4 gig to work, but that may just be me.
For a less troublesome way? h onestly, I use a SD card that I've formatted with the DCIM folder. I've never had one of them trigger the 'too much power' warning. Just make sure they're not SDXC. those don't work.

USB Flash Drive not readable using 10.4.6 but is with 10.3.9

I noticed that a 32MB USB Flash Drive that used to work on my Powerbook when it was running 10.3.9 became unreadable when I upgraded to 10.4.6. This flash drive still works on my Dell WinXP system and I just tried booting the powerbook off a clone of my 10.3.9 setup (on an external firewire drive) and my flash drive works on that. So it appears to me that 10.4 has introduced a software bug that has disabled support for some flash drives. I will note that I also use a USB compact flash reader for transfering digital pictures and that does work under 10.4.6 so the problem does not affect all USB flash devices.
Is Apple aware of this? Are they working on it?

Have you tried to open it in disk utility? Probably won't, but worth a shot. If not and you don't know who made it, then I'd say your out of luck. Probably time for a new Flash drive.
A 32meg Flash Drive today is very cheap if you can find one. You can get a 250 meg Flash drive for $20-$30. That's 8 times the storage you have now.

I need a USB flash drive recommendation for late 2008 MBP

I swapped out an Aluminum MacBook Pro for the new unibody one. Unfortunately, since the 2 USB ports are now side by side, I can no longer use my external mouse and flash drive at the same time due to the thickness of the Cruzer drive.
Anyone out there have a USB drive that DOES fit next to a standard sized USB cable? I need a brand that has sizes 4 GB or bigger. Thanks for any help or suggestion you can provide.

Hi JMF, I had the same issue as you, but I found a USB drive that does fit next to a standard sized USB cable. It is a Verbatim USB Mini Swivel and comes in sizes from 1GB to 8GB. You can get these through the Online Apple store. Hope this helps.

USB flash drive defined as boot device but not visible by the boot driver.

I have installed Mountain Lion (10.8.2) over Lion a few days ago. In the follow-up operations, I tried to create a USB flash drive recovery device, using methods widely advertised over the web. I first tried this with an 8 GB "Kingston DT 101 G2" device. The creation of the device either manually through the use of the Disk Utility or using a small utility called Lion DiskMaker 2.0.2 worked OK.
However, after setting the resulting device as the boot device through "System Preference", it never booted on it, but instead on the normal system disk. Conversely, when booting with the option key depressed, I could only see as option the normal system disk or its recovery partition, but never the USB flash drive, although it was present.
After numerous tests, through the so-called "trial and error" method, I eventually found out that I obtained perfectly bootable USB devices with either a generic device seen as "USB 2 USB Flash Drive" by the disk utility, or with a "Kingston Data Traveler G3" USB flash drive (both being 8 GB devices).
Now, I can understand that, for whatever reason, some USB devices, although formatted as boot devices, will not be seen by the boot driver. But, in such a case, it is a serious issue that "System Preference" accepts to set them as boot devices. I would suggest that "System Preference" tests whether the boot driver is able to see them and, if not, issues an error message instead of accepting them as boot device.
I also have an unrelated side question: when restoring a disk through the Disk Utility, is the resulting new volume defragmented and compacted by the process or not?

I can only tell you that some USB flash drives don't work as expected on Macs, and I don't believe it is specifically related to the product since they often work for others. I have five flash drives from a particular manufacturer that when plugged into one of my computers are not recognized, yet they are on all my other computers. I have six or seven older ones from the same manufacturer, same model, that work fine on all my computers. I have two Kingston Travelers that would not work as a bootable device on any of my computers. Many other users here have had issues with San Disk flash drives.
I don't know if this helps any, but at least you can know that you aren't alone.
One thing I can suggest is when you prepare a new flash drive that you go through this process:
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
This may fix boot problems with new flash drives because they are often prepared by the manufacturer with NTFS. To fully clear the drive you must both partition and format the device. Writing zeros has in some cases helped make a drive bootable when at first it was not.

How do you save videos from iPhoto to a USB flash drive?, How do you save videos from iPhoto to a USB flash drive?

Hello! Could someone please help me? I am trying to save vidoes from iPhoto to a USB flash drive. After I export them, I open my flash drive to play them back and they are all zero seconds long in Quick Time Player. What am I doing wrong?

How are you exporting?
Try to export using the "File" menu and select "Kind > Original".
Then drag the exported video file to your USB flash drive.

Unmounting USB flash drive from cRIO

Hi all,
I am using the USB port of a cRIO 9012 to save datafiles (using File I/O) to a USB flash drive.
After having run the program, I want to unmount the USB drive. Can anyone please tell me if there is a better/nicer way than just taking it out? Since this might result into losing my data if the USB drive gets corrupt (just like under Windows).
I have searched the forums, but I was not able to find anything on dismounting a USB drive on a cRIO...
Hopefully you can help me solving this (little) problem.
Thanks in advance,
Joep

Joep,
under Windows there are two scenarios that could cause data corruption on a USB-Flash-Drive:
The Flash-Drive is removed during a write operation. This potentially destroys the FAT which results in data loss. There is not much that you can do against this behavior, neither on Windows, nor under VxWorks.
With caching enabled for the Flash-Drive there is a chance that files are not written to the drive completely because some parts of it are still sitting in the PC's memory. When the drive gets removed the data is corrupt.
I don't think that VxWorks uses cache for mass storage devices at all so this issue shouldn't be relevant for a cRIO-9012, but I will double check if this is true.
Best regards,
Jochen Klier

USB Flash Drive Issue On iMac - 1.1 on iMac, 2.0 on any other Mac

I have a Core i7 27" Late 2009 iMac.
I just noticed this issue today.
I have a couple of Patriot XPorter XT USB Flash drives that I use among my Macs to transfer big files around.
Hooking one of the 8GB flash drives to my iMac, the one listed above, it shows the device operating at USB 1.1 speeds, whether it's in a powered hub, or one of the 4 USB ports in the back of the machine. This was odd, because this was the first time it had ever done this. I only noticed this due to the painfully slow transfer rate the Finder was reporting to me. Restarting the iMac, cold starting the iMac, resetting permissions, PRAM and SMC did nothing. I thought it was a bum drive.
So I grabbed a 16GB flash drive (same brand and model family, different capacity) and it works perfectly fine on the iMac at USB 2.0 speeds. Hmm...
So I boot the iMac into Win 7 Ultimate x64. Both drives are listed at USB 2.0 speeds. Something is definitely afoot here.
To make sure I'm not losing my sanity, I grab my MacBook Pro and test the drives in there. Both drives are listed at USB 2.0 speeds.
I then run to my Mac Pro. Both drives are listed at USB 2.0 speeds.
Did something go wonky on my iMac?
Machine specs (for comparison above)
iMac 27" i7 2.8GHz - 16GB RAM
MacBook Pro 15" Core 2 Duo 2.4GHz - 4GB RAM
Mac Pro Xeon 2.66GHz - 12GB RAM

I think that you are just running into a communication blip between the thumb drive and the controller for the USB ports on your iMac. It is obviously reading the 8 GB drive as older and slower and is assigning that lessor priority to the bus serving the drive.
Have you tried attaching the drive directly to the iMac with no other device connected to a USB port? If it is the same, then I doubt there is anything that you can do, that is going to be the way the USB controller reads this thumb drive.

My iPhoto photo library disappeared after I used a SanDisk Cruzer Fit USB Flash Drive

Hi! Not sure if these 2 things are connected, but I bought a SanDisk Cruzer 32GB USB Flash Drive. I dragged my documents over and copied them on to the flash drive. I didn't have iPhoto open. I didn't drag any applications, photo library folders, or anything else over to the flash drive. I just dragged over 3 file folders of work and personal documents (MSWord, Excel, etc.) over to the flash drive. It took some time to copy all my documents over, so I left it overnight.
The next day, I decided it might be a good idea to also back up my photos from iPhoto. Interestingly enough, nearly all my photos had been deleted--save for photos from the last 3 - 4 weeks or so. That's right, a decade worth of photos were gone. I went online, Googled the problem, looked through this community and verified that I did not accidentally import one library into another or move (or delete) the backup iPhoto Library folder or anything. I even checked the flash drive. Nothing. Just the 3 folders worth of documents that I'd copied over.
Has anyone heard of a flash drive somehow corrupting or deleting photos from an iPhoto library?
I'm stumped. I have dug through other regular folders where I'd stashed some .jpgs so I could burn a CD for family, so I have put back about 338 photos from a library of thousands of images (some which are, of course, irreplaceable). The irony is that this last year, I'd been scanning in photos from actual physical photo albums to digitize them and have them handy on iPhoto... not knowing that they would disappear. And, of course, the double-irony is that I was using a thumb drive to back up my photos when they disappeared. If I wasn't so bummed, I'd be laughing right now.

Thanks for the helpful thoughts LarryHN. I'm having a Mac guy look at my MacBook Pro in the next day or so to see what he can find out. I described the issue on the phone... and like you, he said that saving my documents to a thumb drive shouldn't affect my iPhoto library.
One reason I bought the thumb drive was to back up my iPhoto library, but the time I got to that, it was already gone. I've thought of getting Time Machine (and have checked out other systems), but the reviews are so mixed, I'm dragging my feet on coughing up the cash right now.
When I launch iPhoto, I only see the last few weeks' worth of photos. Oddly, photos I imported 3 weeks ago appear, but are in a folder dated November 2012--when I know I took those and imported them in January 2013. So that's weird...
When I got to iPhoto Library, I have an Auto Import folder with nothing in it. "My Pictures" folder has nothing as well. I did hold down the option key while opening up iPhoto, but only my recent library (a few weeks' worth of photos) appears. I'm using iPhoto 2011 (6.2.3). I can only hope my Mac guy can help...

Disk erase needed after USB flash drive has been connected?

Hello. I apologize beforehand if this is a stupid question. Unfortunately, it looks like I'm going to have to return my new iMac because of a faulty screen. I have held off transferring files to see if the screen would be problem-free, but at one point I did connect a USB flash drive to my iMac. I copied just one file onto my desktop. My question is: when the flash drive is connected and files show up in the Finder window, does that mean there is now a lasting imprint of those files on my hard disk, even if I haven't actually copied them onto the desktop? I ask this because the flash drive has some sensitive data on it, and I'm debating whether or not to do a 7-pass erase before returning my iMac. Any response would be greatly appreciated. Thanks!

If you mean the Finder window showing the contents of the flash drive, no, there's nothing retained on your Mac from that collection of files once you dismount the flash drive.

How to install (using usb flash drive) os x snow leopard on 10.5?

i have a version 10.5 (leopard), but i would like to install snow leopard (10.6). i tried using bootable usb flash drive using the "utility drive". However, it did not quite work as i expected. Does anyone know how to use bootable usb flash drive to install snow leopard on leopard?

How to Install OS X Updates Successfully
A. Repair the Hard Drive and Permissions:
Boot from your current Leopard installer DVD. After the installer loads select your language and click on the Continue button. Then select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger) and/or TechTool Pro (4.5.2 for Tiger) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
B. Make a Bootable Backup Using Restore Option of Disk Utility:
Open Disk Utility from the Utilities folder.
Select the destination volume from the left side list.
Click on the Restore tab in the DU main window.
Check the box labeled Erase destination.
Select the destination volume from the left side list and drag it to the Destination entry field.
Select the source volume from the left side list and drag it to the Source entry field.
Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal startup drive.
C. Important: Please read before installing:
If you have a FireWire hard drive connected, disconnect it before installing the update unless you will boot from this drive and install the update on it. Reconnect it and turn it back on after installation is complete and you've restarted.
You may experience unexpected results if you have installed third-party system software modifications, or if you have modified the operating system through other means. (This does not apply to normal application software installation.)
The installation process should not be interrupted. If a power outage or other interruption occurs during installation, use the standalone installer (see below) from Apple Downloads to update. While the installation is in progress do not use the computer.
D. To upgrade:
Insert the USB flash drive.
Restart the computer.
Immediately after the chime press and hold down the "OPTION" key.
Release the key when the boot manager screen appears.
Select the icon of the USB flash drive and click on the arrow button below the icon.
When the installer finishes loading follow the onscreen instructions.

Creating Recovery Media using USB Flash Drive for Windows 8.1

I followed all the instructions to create a USB Flash Drive Recovery Media (insert 16 GB USB Flash Drive or >) and it said it will be created now (after I clicked on Create), however the next screen said to insert > 7.5 GB flash drive, then it said it was cancelled. I was attempting to use a San Disk Flash Drive and I am wondering if it is because it has some time of application on it. I was under the understanding that it would just "delete/erase" this (format it) and then create it, but it wouldn't. Any suggestions?

In Windows 8, one can create a "recovery drive" (called a System Repair Disc in Windows 7) that does not contain the recovery partition. (When you install Windows 8 yourself, there is no recovery partition.) It contains just the recovery environment.

Using USB flash drive to connect laptop

On previous versions of Network Magic, when adding a laptop to my wireless network, an option would appear for using a USB flash drive to transfer settings and/or password to the new machine.
After a few "upgrades" to NM, the option ONLY appears after I turn my security off. If I leave my WEP security ON, the only option that appears is to "copy" the 32-digit password & enter it on the laptop. However, I keep getting errors.
Is there a procedure to use a USB flash drive to connect a "new" laptop to my secured wireless network?
Thank you.

Hi thomas,
If this is your own New Laptop to your Network, and even after you supplied the password, the problem is the Network Lock is still on. You need to disable the Network Lock. Enter the password, installed Network Magic if the Laptop is your own. You need to stop tracking your Laptop as an intruder on your other copies of Network Magic.
Then you need to reenable the Network Lock from your Wired Computer. Use your other computer to activated the copy of Network Magic installed on the laptop.
