USB FLASH DRIVE WORKS ON MAC BUT NOT ON WINDOWS... CAUSE I ERASED IT IN MAC

I decided to take my work flash drive home to work on a file. At home I saw that some weird files were on the flash drive and wouldn't delete, so I decided to save my files on my Mac and erase the USB flash drive. I selected the flash drive (by the way it's a 2 GB flashdrive) and I used the SECURITY OPTION 35 PASS ERRASE. Format: MS-DOS (FAT).
Everything was fine until I took my flash drive to work and plugged it on a Windows XP Computer and it appeared as Drive E I think and when I tried to open it it asked me to format it. I risked it and clicked OK and it said that I didn't have sufficient rights or something.
SUMMERY:
2 GB USB ERASED USING MAC DISSK UTILITY
EVERYTHING FINE UNTIL I PLUG IN THE FLASH DRIVE IN A WINDOWS
WINDOWS ASKS ME TO REFORMAT FILE
I PLUG IT INTO A MAC COMPUTER AT WORK AND IT DOES WORK
IF ANYBODY KNOWS HOW DO I FIX THIS THANKS?

The drive is probably now formatted for a Mac only file system. To format for a PC:
Insert the drive in the Mac and start Disk Utility (Utilities folder).
Select the drive in the left column. Be sure to select the drive (all the way to the left) not a volume (indented below the drive name).
Select the "Partition" tab.
Set "Volume Scheme" to "1 Partition" (not "Current" even if it's already one partition).
Click the "Options" button".
Select "Master Boot Record".
Click the "OK" button.
Enter a volume name (all uppercase).
Set "Format" to "MS-DOS (FAT)".
Click the "Apply" button.

Restore SSD from USB Flash Drive Clone

Hi,
My sister bought me a 512gb Samsung 830 SSD which I wanted to format using a 32gb USB flash drive which I'm using as a boot disk (Clone of my orginal hard disk using Carbon Copy). However, When I open up the Disk Utility and go to restore the SSD using the USB Flash drive I get an error "The startup disk can't be used as a restore source: To use this disk as a source, restart your computer using the recover system, and open the Disk Utility again." I've restarted several times but always get the same response. What am I doing wrong?

I figured it out, I actually needed 3 things:
1) Carbon Copy Cloner
2) 32GB San Disk Cruzer USB drive
3) Plugable USB 3.0 HDD Docking Station
Step 1: Cloned my old hard drive and created image unto my desktop
Step 2: Format USB drive and restore USB flash drive using Carbon Copy cloner
Step 3: Shut down compter, remove usb drive and install ssd drive into computer (http://www.ifixit.com/Guide/MacBook-Pro-17-Inch-Unibody-Hard-Drive-Replacement/3 401/1)
Step 4: Install old hard drive into Plugable USB 3.0 HDD Docking Station
Step 5: Connect Plugable USB 3.0 HDD Docking Station with your old hd installed in it to USB port
Step 6: Start PC....allow the computer to book from the Plugable USB 3.0 HDD Docking Station
Step 7: Connect USB Flash drive to Macbook
Step 8: Open Carbon Copy Clone and restore the USB flash drive onto the ssd drive
Step 9: Once complete....shutdown macbook pro and disconnect both the USB flash drive and the Plugable USB 3.0 HDD Docking Station
Step 10: Turn on macbook pro, it should boot from ssd now (It's so freaking FAST!)

HP Mini 110-3520ca constantly restarts when trying to restore from usb flash drive

Hi,
I have a HP Mini 110-3520ca that I upgraded to Windows 8, but was having issues with freeze ups and shut downs so I decided to go back to Windows 7 Starter. When I tried to restore to factory default the files were corrupted and I couldn't restore from the recovery hard drive or my external back up files. I ordered the recovery USB flash drive from HP and tried to restore from it. It completes the Recovery Preparation and the Software Installation finishes, Windows starts to load, but Ithen it goes back to welcome to Recovery Manager. When I try to start Windows without the flash drive I get an error log that is below. Can someone tell me how to fix this or what needs to be done to get my Windows working again, any help would be greatly appreciated.
Carol.

Hi @Savvy58
I did some further looking into that Error Log you posted. Basically, it means that is looking for a certain location that doesn't seem to be there. This could be a problem with the USB Recovery drive that you have. I would recommend that you contact HP. You can reach HP Total Care at 1-800-474-6836 in North America or start here if you live outside of North America.
Please click “Accept as Solution ” if you feel my post solved your issue.

How to erase USB flash drives?? Thanks, Michael

How to erase USB flash drives on my MacBookAir ?? Thanks, Michael

Welcome to Apple Support Communities
To erase them, you can use Disk Utility, in /Applications/Utilities > http://pondini.org/OSX/DU1.html
When you open Disk Utility, choose the external disk in the sidebar, go to Erase tab and erase the disk

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 reformat a USB flash drive?

I have 1.33 GB available on my Buffalo USB 2.0 GB Flash Drive that is formatted as MS-DOS File System (FAT 16).
Suddenly, every time I try to copy a MS Word document from my iMac to the flash drive I get the following message.
+"The item cannot be copied because there is not enough free space."+
I reported this to the Buffalo customer service and they responded with,
+"When you look at the files in the USB flash drive, do you see a lot of temporary files? Please delete these. If there is no other solution, I would like you to copy your good files onto your computer hard drive, reformat the USB drive, and copy the good files back onto the USB drive. "+
I did not see any temporary files, so I'm thinking that I have to reformat the flash drive.
But how do I do this?
I've backed up the files on the flash drive to my iMac.
I insert the flash drive and click on Disk Utility.
I select the flash drive icon and...
What do I do now?
The choices at the top are First Aid, Erase, RAID, Restore.
BTW, I am running on a iMac 2GHZ Intel Core 2 Duo, 2 GB 667 MHz DDR2 SDRAM, OS 10.4.10.
As is evident, I have no idea about computers.
Please advise on a step-by-step basis.
I thank you in advance for your assistance.

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.

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 to format USB flash drive?

I recently received a USB flash drive at a traveling covention. It has two partitions and one is unwritable and is filled with travel brochurs etc etc. I was wondering if it was possible to reformat the whole thing back into 1 partition. I already tried disk utility. Thanks!

Drive Preparation
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. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.

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.

Why won't my USB flash drive work?

I am working between two Macs in my house: the upstairs one is MAC OSX 10.6.8, and the downstairs one (an eMac) is MAC OSX 10.5.8 -- if that matters.
I need to transfer files from the downstairs computer to the upstairs one.
When I insert a USB flash drive into the upstairs Mac, I am able to save files to it and from it. (I have already read about the correct way to format the flash drive for FAT 32 and read/write, and I eject the drive correctly when I'm finished.)
Then when I go insert the flash drive into the downstairs Mac:
the flash drive appears on the desktop
I'm able to open it, to see the files saved to it
I can save files off of it, BUT
I cannot save files to it. I get a message that there isn't enough disk space, which is incorrect -- there's plenty of memory
I have tried opening Disk Utilities on both MACs, erasing the flash drive's contents, and reformatting it, but I get the same situation.
I'm guessing the solution is simple and involves the eMac's preferences. Am I on the right track?
Frustrating.
Many thanks for your help!

Niel:
Thanks for the reply!
The file on the eMac that I'm trying to transfer onto the flash drive is far less than 4GB.
So I went onto the eMac's Disk Utilities and reformatted the flash drive as Mac Extended: still no dice. Even with the contents of the flash drive erased, any attempt to copy files onto it resulted in the same "not enough disk space" message.
So I tried reformatting the same flash drive on the upstairs Mac. Same thing. I tried reformatting the flash drive both as "Mac Extended" and "Mac Extended (journaled)."
Thoughts?

Does Time Machine back up USB Flash Drive?

I have a 128GB USB Flash Drive. The contents of this flash drive was restored from a previous external SSD (used as storage and has died on me).
Now I would like my Time Machine to backup both my MacAir and my USB Flash Drive.
My First Concern is
So when I plug in my USB Flash Drive, it appears in the Exclude List.
However, after I remove the USB Flash Drive from the exclude list and click on Save.
I start to Back Up using Time Machine.
Does it mean that time machine will back up my USB Flash Drive for this One Time?
Because when I open up the Time Machine preference, the USB Flash Drive re-appears in the Exclude List again.
Second Concern
When I open the HDD I use for Time Machine, I noticed that the latest backup consist of both my MacAir
and the name of my Previous External SSD (instead of my current USB Flash Drive).
I am wondering if Time Machine recognise my current USB Flash Drive as my previous external SSD
since I restored my contents from there.
So is my USB Flash Drive really backed up (just that Time Machine recognise it as my previous external SSD)?
Hope someone can share their experience and advice on this.
(Please do not recommend other app like Carbon Copy Cloner, as I already plan to use the CCC Trial.)
Thank you to all.

What is the format of the volume on the flash drive? It's shown in the Finder Info window.

[SOLVED] Clone Archlinux to USB flash drive

Hello,
I want to clone an existing Archlinux installation (x86-64) from a hard drive to a 32 GB USB flash drive. I want to be able to boot from the USB stick on my Win7 labtop.
I already took some measures to prepare my hard drive (with gparted). After moving all movies, pics etc to external stores and shrinking the home drive (sda4), it now looks like this:
- sda1 Boot (small)
- sda2 Swap (small)
- sda3 Root ( ca.8GB)
- sda4 Home (ca. 22GB)
I tried to take an image of the entire hard-disk (ca. 250GB) with clonezilla and restore it to the USB flash drive, but got an error message - original disk to big (250GB vs 32GB), besides only ca 30GB of the 250GB being assigned to partitions.
Now I'm looking for a way to bring only the necessary partitions from the harddisk to the USB stick, hoping to have exactly the same Archlinux configuration as a bootable installation on the USB stick afterwards (bootable on a Win7 labtop ... and maybe from my main Archlinux machine too). There is a wiki article about the topic, but its rather about installing a fresh system than cloning an existing system. The related questions on the forum (searching in 'installation' for 'clone usb') did not answer my question.
Maybe somebody did successfully what I'm planning to do and can give me some tips?

I prefer Gparted, it's easy as cake
The filesystems don't have to be the same as the original partitions. I prefer ext4 (universally supported) or jfs (uses very little CPU), but I recommend you ext4.
In fact, you can use a hard drive instead of a flash drive and this is how you clone a Linux installation manually!
4on6 wrote:So I mount both - source and destination partitions (/mnt/dest/ suggests it ...)?
Yes. I mount the source partition in /mnt/source and the destination partition in /mnt/dest, and then I issue
rsync -av /mnt/source/ /mnt/dest
and wait for it to finish. Then I unmount the partitions and mount the other ones and repeat the same thing.
4on6 wrote:I create that /boot folder on the flash drives root partition, right? Won't that cause problems later on with rsync, when I update the installation and there is an additional folder on the target partition?
Since the root directory you'll aready copy on the flash disk won't have the /boot directory, simple do a
mkdir /mnt/dest/boot
while your destination partition is still mounted. Unmount the source root partition, mount the boot one and then type:
rsync -av /mnt/source/ /mnt/dest/boot
and GRUB and the kernel will be copied to the /boot folder on the destinaton partition on the flash disk.
Make sure that in /mnt/dest/etc/fstab you comment out the line for mounting the /boot partition, if any.
4on6 wrote:I've seen those UUIDs as output of a linux command (mount? fdisk?), but I don't recall which one - how do I get these UUIDs?
Use Gparted, right click any partition and click Information. In the window that appears, in the middle you can double-click the UUID and press Ctrl-C to copy it. Then you can paste it in the text editor and use it for /etc/fstab or /boot/grub/menu.lst. That's why I love Gparted for such stuff.
4on6 wrote:Do I send this command from the live Arch-CD, and is it the only command necessary (I have not much experience with grub)?
Yes, since Arch uses GRUB 1 on the installation CD you can uste the command I gave you to reinstall GRUB on the flash disk with the settings you already entered for the /boot/grub/menu.lst file.
Make sure you boot the CD in 64 bit mode if the Arch you installed is 64 bit. Just to be safe.
4on6 wrote:I will ...
Be very careful, I didn't and lost ALL my files by mistake in typing. Triple-check the directory you are currently working in! ALWAYS make a backup!

You're welcome. Please inform me if this little tutorial suited you so I can make a wiki entry for it, if the admins allow.

USB Flash drive not showing on DT

Hi folks,
I received a USB flash drive with 2 GB capacity made by Super Talent (www.supertalent.com- look under Aluminum flash drives).
Upon plugging it into the G5's USB port (i've tried them all) I get a "Cannot recognize- Initialize/Ignore/Eject" message. Clicking Initialize brings up Disk Utility which sees the drive with a capacity of..wait for it..2 Terabytes! Here's DU's info:

hey there scan,
I gave the drive to a friend who has an iMac. Samething occurs: drive does not mount, DU erroneously reports 2 TB capacity and coughs up the beachball seconds after clicking on Erase to format it. He's on 10.3.9 while I'm on 10.4.6.
All the ports on my G5 are in working order as i use printer/scanner and iPod w/o problem.
Think the drive is going back.

USB Flash Drive not detected after OS X Mountain Lion installed.

My MacBook Air 11 inch (Mid 2011) suddenly stopped detecting all my USB flash drives a week after upgraded to Mountain Lion.
I have a tiny 16GB USB flash drive (Sandisk Cruzer Fit), for daily work, that has never been unplugged from my MBA.
Everything was fine on Lion, and a week of Mountain Lion, until just when my MBA prompted me that my flash drive "was not ejected properly" after I re-opened the display/lid, or from sleep mode.
I thought I might have accidentally removed the flash drive unknowingly. So I tried re-plugging the flash drive, closed and re-opened the MBA lid, and the same error message "The disk was not ejected properly" occured. I repeated the steps for a few times (thinking my flash drive might be faulty) and at my last attempt, the flash drive was stopped detected. I tried several USB flash drives and external hard drives (of various brands) to both the USB ports of my MBA, only the external hard drives were detected (on both USB ports) and functioning. None of the flash drives was detected on either USB port.
The tested flash drives were plugged to another 13" MacBook (Unibody, Late 2008, OS X Lion) and they all worked fine.
I wonder if anyone faces the same problem, and solution(s) please?
Additional: OS X Mountain Lion re-installed and same problem occurs / No problem with OS X Lion.

I had the same issue after installing Mountain Lion from the App store. The issue is you are missing the IOUSBFamily.kext extension amongst others. The solution is to backup your macbook, then perform a clean install of Mountain Lion.
I had this done at the Apple Store and now everything is restored as well as performance speed being improved.
Note: When restoring your files (a clean install will delete all your files and applications), use the Migration Assistant.
I would recommend going to the Apple Store to do this because they can perform the clean install from a USB which is so much faster than the download form the App store.
Hope this helps.
