Problems mounting USB thumb drives and transferring files

My iMac 24" (10.5.4) won't recognize a USB thumb drive (even if plugged directly into computer, not hub) unless I restart. Then when I try to transfer large number of files back or forth from thumb drive, it won't complete the transfer, gets hung up.
None of these problems with my Intel MacBook (also 10.5.4).

You might try reformatting the usb drive using Disk Utility. Use MacOS Extended(Journaled). That might help.

POSSIBLE? Copy USB thumb drive image to file and rebuild it to use the USB drive ?

I bought an 8GB USB thumb drive and used it to create an install boot disk to boot for install or use disk utility to clone my system drive for failsafe. In other words it is called "Install OS X Mavericks" and I can boot from it.
SO, it just sits there and does nothing while I am not using it, and in the meantime I have some documents I need to get printed at Kinkos and class notes to carry around, and this drive could really be useful to do that, rather than waste time and money to buy a new one and keep track of them all. You know how these things always get lost of broken and you end up with a few of them and never know what's on them?
So ... in UNIX style I tried to do a dd of the drive "dd if=/dev/disk2 of=$HOME/usbdrive.dmg bs=4096" - assuming a 4K block size would work.
The system does not seem to recognize it, so I'm doubting if that was the correct way to do this, or if this can be done at all.
What I want to do in short is to not bother with formating or anything like that, and just create a disk image that I can store around until I need to put it in my USB drive to boot for an install, rebuilt, clone system drive, etc.
Can this be done, and does anyone know how to do it?
I do have Mavericks Server, but I'm not sure how or if the System Image Utility will do this? It sees the drive, but it just give me options to make a Net Boot Image, NetInstall Image, or a NetRestore Image ... and I do not know if any of those options will allow me to put it back on the drive when and if I need to?

The command you want is
sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Mavericks.app --nointeraction
This command only works if "Install OS X Mavericks" is in the Applications folder and a 8GB usb is erased and named "Untitled". Change the command as you see fit.

Mounting USB Hard Drives and Hard Locking

So, it's been a long time since I've posted here which I have to say, is because Arch was running beautifully for a long time. Sadly though, my laptop was stolen and I was forced to buy a new one. With the new one, I've gotten everything mostly back up and running but I'm having an issue. Obviously the one in the subject line.
A few things to note about this install and after testing before posting.
1. Brand new install
2. All packages are current EXCEPT 3. I currently have nvidia-256.53-1-x86_64, nvidia-utils with the same version, and kernel26-2.6.35.5-1. These are due to a black screen I was getting on starting my xserver.
3. HAL is running
4. Optical disks mount and umount cleanly.
5. NTFS-3G is installed and working.
6. My Windows 7 install on the same internal hard drive can be accessed and mounted without a hard lock.
My problem is this. Whenever I try and connect an external hard drive via USB, it takes a few seconds and then the whole machine hard locks with what looks like a kernel panic(can't do anything and I have blinking lights...ie capslock, etc). This computer seems to have USB 3.0 which I noticed from Win7 awhile back if that makes a difference. (05:00.0 USB Controller: NEC Corporation Device 0194 (rev 03) )
Last time I try to mount my WD Passport, I ran dmesg right after I plugged it in before I got my hard lock. The only thing I noticed were the entries at the bottom of things like this...
xhci_hcd 0000:05:00.0: WARN: Stalled endpoint
I have no idea whether that has anything to do with it or not. I'd be more than happy to post config files if needed. I've tried googling, the wiki, and the forums and I'm stumped. I actually plugged my drive in one time and got it to mount and opened some folders. Afterward, it hard locked.

Backup drive and transferred files not found

I recently purchased a time capsule. I transferred some files from an older hard drive to the TC (they appeared on the TC) and then backed up my PowerMac G5 (wired directly) and my MacBook Pro (wirelessly) to the TC. The initial backups for these two computers worked fine, but I am now encountering two problems.
1. The files I originally transferred from the old hard drive now don't appear on the TC (although it looks like they might be there based on the amount of TC drive space occupied). Is there anyway to access these older files (assuming they are still there)?
2. Frequently when I try to enter TC from the PowerBook Pro, it says that hard drive not found. Also, it doesn't back up automatically. The only back ups are those I have done manually. The TC seems to be working fine with the wired PowerMac G5.
I would appreciate suggestions on either topic.

1. Have you changed the file sharing access on your Time Capsule since you copied your files? When you use the Time Capsule file sharing without accounts setup you have access to all of the disk. When file sharing with accounts is enabled you have access to a Shared file (where everyone has access and where your Time Machine backups are kept) and then to your own personal file (where only you alone have access). You no longer have access to anything that is not in the Shared file or your account file. If you have enabled account access then I would suggest turning it off which would then give you access to the whole disk and then moving the files you are referring to either into your Shared folder or your Account folder.
2. Go to System Preferences, Time Machine, and then Change Disk. Select the name of your Time Capsule (this won't overwrite or delete any of your previous Time Machine backups). This should hopefully fix the problem.

Prepare an usb thumb drive, to boot windows 7 or 8 in UEFI mode

Purpose of this post:
Prepare an usb thumb drive, to boot windows 7 in UEFI mode and install the system in pure UEFI mode.
Why am I writing this:
I had a hard time finding out how to make a custom installation of windows 7 in pure UEFI mode, and avoid using the factory restore disks. After hours of research, experiments etc I finally got the point and found a solution. And I'm happy to share my research with you. I hope this will be of help. If something is not clear, or more information is needed, I will be glad to explain things further.
History:
As most of you already know, BIOS was developed for PC in early eighties and has remained unchanged in recent years. But, since 2000, Intel started working on a new firmware interface, called Extensible Firmware Interface, abbreviated EFI. And since 2005 United EFI Forum has been handling the responsibility for development, management and promotion of UEFI specifications. Bigger companies like Intel, AMD, Microsoft and Dell have already started to bring out their products in accordance to UEFI standards which has more stable, secure and easier to use interface.
How does UEFI works (in a nutshell):
Once you power on the UEFI based PC, the Pre-EFI is executed which initializes only the CPU, memory and the chipset. This followed by Driver Execution Environment (DEX) where other hardware is initialized.
Advantages of UEFI:
    It can integrate various drivers this will not require to load during booting so saves time.
   PC can connect to network without OS.
   Also integrated drivers allow rendering GUI based control panel which out dates the old school bluish BIOS screen.
   Not all the installed hard drives are scanned as boot drive is set during the installation of OS in UFFI.
   Applications like anti-virus and diagnostic tools can be stored on virtually any non-volatile storage devices attached to a PC.
For a system to boot and install in UEFI the partition table of the HDD should be GPT (GUID Partition Table), not the old school MBR (master boot record). GPT has many advantages, can have virtually an unlimited number of partitions (windows will allow only 128) and impressively big partitions.
Since UEFI has a lot of advantages why not having a system install and boot in UEFI mode? AFAIK new Lenovo notebooks/netbooks are UEFI capable and OS’s are already installed in pure UEFI mode.
So, let’s go now to the point. Do you want to have more control over your HDD? Let say, you have a 320GB HDD and you have divided it in two partitions, one of 50GB, for your Windows 7, and the remaining for your data. If something goes wrong and you need to restore your system to factory default, with the recovery disks, it will wipe your partition scheme, set the system to default and this way your data will be lost.
You may want to make a “vanilla” installation of windows from a USB thumb drive and avoid using factory recovery disks. Now here things get complicated. A standard preparation of the USB with Microsoft’s software (Windows 7 USB/DVD Download Tool), or other tools, will give you a bios installation, not a UEFI one. So for the system to boot, you will need to change some settings in bios, and changing it from UEFI to legacy bios. The installation will prepare the HDD in MBR partition table, and you will lose all the advantages of UEFI, described above.
Now this can be avoided, by properly preparing an USB to boot and install in UEFI mode. Here are the steps:
Step by step tutorial:
1.   In a windows computer, download a legal copy (although trial) of the windows 7 os. You can do this from here: http://www.mydigitallife.info/official-windows-7-sp1-iso-from-digital-river/
Be sure to download the same version that came preinstalled in your computer. For example, if you have a Lenovo x120e, with a Windows 7 professional, 64bit, download an iso image of the Windows 7 professional 64bit.
2.   Once downloaded burn the iso to a USB thumb (at least 4GB) using Windows 7 USB/DVD Download Tool.
3.   After preparing this, create a folder on your computer, name it whatever (i.e. W7pro64bit). Go to the root of your USB
and select all the files and folders there (9 in total) copy, and paste to your folder you created, W7pro64bit.
4.   Using windows format the usb again in FAT32. Windows 7 USB/DVD Download tool, formats it in NTFS. We need a FAT32 formatted disk to achieve our goal. Formating again the USB in FAT32 will not touch the MBR of the USB thumbdrive. And after copying back the files (see step 6) the USB will still be bootable. (nice, and simple, isn't it?)
5.   Now go to the folder W7pro64bit and do the following:
a.   Browse to W7pro64bit\sources\ and open install.wim file. It’s a big file, and can be opened as an archive with 7zip (free software). Do not extract it, do not modify it, just browse the file with 7zip. Just to be sure you do not mess with that file, you can copy it somewhere else in your computer, and than procede.
b.   Browse this file (install.wim) to \1\Windows\Boot\EFI\ and locate the file bootmgfw.efi. Do not move, delete it, but just drag that file to the desktop. (if you have copied the file install.wim to another place in your computer, than you are safely do whatever you want with that file ) Close the 7zip program to release the install.wim file.
c.   Rename the file you just copied to the desktop from bootmgfw.efi to bootx64.efi.
d.   Now go back to w7pro64bit folder and browse \efi\Microsoft. Form there copy the folder boot and paste it one level up, on the folder: \efi. It will look like this: \efi\boot.
e.   Now copy the file you saved on your desktop and renamed (bootx64.efi) to \efi\boot (inside the boot folder you copied on step 5d
6.   Now go to the root of the folder W7pro64bit and select all folders and files (9 in total) copy, and paste all those files back to your USB thumb drive. (see step 4 for more info)
7.   Go to the computer that you are going to reinstall, and before restarting it, use the program ABR (activation backup and restore) to backup the license of your windows os. (use google to find ABR). Advanced Tokens Manager (ATM ) is great too. This link may be of help: Backup and restore W7 activation. After the program finishes its magic, it will create a few files inside the folder where the program itself reside. Copy these files to a new folder in your usb. Rename it to ABR so you will quickly find it later. (if you decide to use ATM, the procedure may be a little different. But you are smart enough to figure out how to use it)
8.   Backup to an external storage all your data before continuing.(reminder: are you sure you saved the license as explained in step 7, to a safe place? To a external drive, to another computer? If you are sure, than go on with step 9)
9.   Now restart your laptop, and enter your bios settings. Go to the boot settings, and set the computer to boot in UEFI only. Not both, not UEFI first, or legacy, BUT UEFI only. Save and restart.
10.   Press f12 (or the corresponding key for your machine) to choose the boot device and chose to start from the USB thumb drive with your windows 7 pro 64 bit.
11.   If everything is done correctly, your computer will boot from the USB.
12.   Follow the wizard and choose a custom install, not upgrade. At the disk partition window delete all the partition you see there until you have only one unallocated space.
13.   Select it, and click next to install windows, without making partition in this point. The installer will create a GPT partition table not a MBR since the USB booted in UEFI mode.
14.   Immediately after the first restart remove your USB thumb, and the installation will continue from the HDD. Wait until installation finishes.
15.   When you will be finally on your desktop, on the installed OS plug your USB go to the ABR folder and click on restore.exe. It will restore your license and your copy of windows will be activated.
16.   Now you can go in computer management/disk management and shrink the HDD to create your partitioning scheme. Make sure to leave enough space to your windows os. (30gb or more for extra programs you will install at your choice)
17.      Download from lenovo.com thinkvantage system update and update your system. Windows update too can install all the necessary drivers, if you need only basic drivers support.
Note: if tvsu will fail to work, see this:
http://forums.lenovo.com/t5/ThinkVantage-Technologies/ThinkVantage-System-Update-Servers-down-the-wh...
It may look a looong tutorial, but once you do this for the first time, it will look a piece of cake.
Final words:
From now on, you can install windows 7 in UEFI mode with your special USB without changing your partition scheme anymore. If you have a data partition beside your os partition (see the example above), when you reinstall the system using your USB thumb drive, at the disk partition window chose the partition where windows is installed, delete it, and reinstall windows to the unformatted area. Your partition with your data will be intact and the installation will automatically mount your data partition to the system. And, all the scope of this procedure, you will always have a pure UEFI installation of the system, with all its benefits.
Have fun!

Thank you, as I noted here, your post was the key to my getting a Windows 8 SecureBooting setup on a W530.
In the case of Windows 8, I needed to copy the files away, reformat my USB key as FAT32 and copy the files back, and viola I was able to boot from my USB install media with the BIOS set to only boot UEFI. From there, there rest was easy (for Windows 8, the copying and renaming is not necessary, the key is having a FAT32 partition on the USB media, rather than an NTFS one; the EFI files are already in the right location).
Thank you again good sir.
You are welcome... and I'm happy that the change of the file system helps with windows 8 too. Thanks for confirming that.

USB thumb drive does full backup every time its plugged in

4GB Corsair USB thumb drive.
1 Partition, MBR, HFS+
I have 2 computers. PowerMac G5 and Macbook Pro. Each have there own Time Machine drives. Each time I plug my USB drive into one of these computers, syslog has this:

backupd[7080]: Post-back up thinning complete: 1 expired backups removed
backupd[7080]: Backup completed successfully.
Now, if I go plug the USB drive into the other computer, the same thing happens, and this cycle repeats over and over again. I tried re-formating the drive, deleting the backups from both Time Machine drives and starting from scratch. No luck.
Thing is, I have a smaller 1GB usb thumb drive and it doesn't exhibit this behavior. I could go back and forth between computers and there is no UUID match problem. I guess for now I can exclude the USB drive from one of the computers and only have the backup on one Time Machine drive, but that is not optimal.
The only difference between the two USB drives is the partition scheme. On the 1GB, it is using Apple Partition Map and 4GB is using MBR. The reason why I am using MBR is because with MBR the 4GB drives formats to 3.75GB, with APM 3.62GB and with GUID (intel macs) 3.42GB. So MBR gives me the maximum space.

For a PPC mac the partition map for a Time Machine drive must be APM. For an Intel mac it must be GUID. In fact both kinds of mac are being successfully backed up to the same drive by some posters, but I doubt you'll get much luck with a partition map that isn't one of those.

OS X Lion USB Thumb Drive - do I need it?

Hi,
I bought OS X Lion USB Thumb Drive and feel doubtful about the necessity of such an expensive purchase
Can someone tell me in which cases (with Lion installation) I can't definitely do without this OS X Lion USB Thumb Drive?
Thanks!

Relative to $29.00 for the download, if you want expensive then price a boxed Full Windows 7 install. (http://www.microsoftstore.com/store/msstore/en_US/pd/productID.235488300?Icid=Wi nCat_CModLink_Win7HP_PID_235488300)
Here is some info I gleaned from the net to educate myself on the usefulness of the Lion Thumb Drive.
The Thumb Drive is OS X Lion sans Internet. Apple's USB Thumb Drive does exactly what it's supposed to do: unleash OS X Lion. If and when something breaks, you won't have to rely on Apple's Internet-based Recovery HD to restore your Mac. The OS X Lion USB Thumb Drive is an easy, elegant, and efficient way to install Apple OS X Lion without relying on your Internet connection.
The USB drive doubles as a Lion recovery disk, meaning you can use the thumb drive to revive (or try to revive, at least) a sick Mac.
When you boot from this drive or DVD, you’ll see the same Mac OS X Utilities screen you get when you boot into restore mode.
I have used mine to upgrade three intel Macs which is much easier than downloading even once. I also upgraded a my 10.6.8 Bootable rescue thumb drive I made to run disk utilities for trouble shooting.
Best of all I dont have to depend on a Internet connection or an external DVD drive. Independence is priceless.

USB thumb drive not mounting... hardware or software problem?

I have two systems I'm working with. The first is a MacBook, running 10.5.6 (also Parallels 4 for WinXP). I have no problems here.
The problematic system is a MacPro, running 10.5.6 (and Parallels 4 for WinXP).
Symptoms:
All USB ports function (sort of). I can plug my keyboard in to any port and they work. If I plug a thumb drive in (to any port), it periodically flashes, but never mounts, nor is it visible in Disk Utility or System Profiler.
If I start Parallels with the thumb drive inserted. It asks me what I want to do with the device, and I can tell it to mount on the mac, and it does. If Parallels is already started, then I insert the thumb drive, nothing (Mac OS or Parallels) notices it was inserted.
If I boot Windows directly, then insert the thumb drive, it tells me the port is not a high-speed port, but will still mount the device.
Finally, again, I have no problems with this thumb drive on my MacBook.

Roger
This may be sorted out in the Preferences for Parallel. In the configuration editor>usb option>connection options.
With parallels running does it see the usb in the menu under devices when you plug it in?

USB thumb drive crashes MBP and PowerBook G4

Hi!
I have a USB thumb drive. It mounts on the Desktop (as two drives, which is not strange because it has both an internal 6 MB of memory and a 2GB SD card) and I can open them. But if I attempt to copy a file either to or from the drive, the Finder hangs forever.
This problem exists both on a shiny new MacBook Pro with 10.4.7, and a PowerBook G4 with 10.3---in either case, I must hard-reboot the machine.
DiskUtility says that the drive checks out OK.
Any thoughts? I tried reformatting the thumb drive, which worked temporarily; but when I added a file to the drive on another machine and tried to transfer it to the Mac, the thing hangs Finder again.
I don't have any problems with the drive on PCs, and I don't have the problem with other USB drives on the Mac.
Xcott

It sounds like the file system is corrupt. I am assuming it's FAT32. I would reformat the drive partitions on a Windows machine and see if that helps.
Also, because it's a dual, you might want to make certain that you do not plug it into a hub or a keyboard but directly into your Mac's USB host port. It may need additional power...
Good Luck!

Toshiba 64GB thumb USB drive [out of the blue] keeps telling me it is WRITE PROTECTED... everytime I try to save a file.. I myself are only user and NEVER write protected anything... HOW DO I GET IT OUT OF WRITE PROTECT MODE ????????????? Serial No. 1129DA0800J2JMK
According to the WEB this is a major problem with Toshiba products. I am a faithful customer I have two of their lap tops so I thought why not buy a Toshiba USB thumb drive. With no warning it just keep telling me it is write protected. I have tried to force a format just to push it back to life but no luck. I have tried to contact Toshiba customer service on their web site and no response. DOES ANYONE KNOW THE SECRET RITUAL TO FORCE IT OUT OF WRITE PROTECTION MODE????????????? Never dropped or abused or left out in the hot sun.. It got this way just lying on the desk. Come on Toshiba... How about some customer service.......

If you still have that thumb drive, try cleaning it with DiskPart. At an elevated command prompt remove the partitions and create a new one. It's something like this. Be sure you identify the correct drive!
DISKPART> list disk
DISKPART> select disk (id)
DISKPART> clean
DISKPART> convert mbr
DISKPART> create partition primary
DISKPART> select part 1
DISKPART> format fs=ntfs

USB thumb drive mounting issues in Lion?

Hi all,
I just installed Lion on my mid-2010 13" MacBook Pro a couple of days ago. All seemed to be going great until I tried to use my USB thumb drives. I have four of these (3 Sandisk and 1 Imation), and none will mount. When I go into Disk Utility I can see them, but when I try to mount them manually the response is "Mount Failed" and some text regarding running Disk First Aid. However, even when I repair the volume, it still won't mount. This happens with all four drives, and I used them all without incident a few days ago when I still had Snow Leopard installed. They are all formatted for FAT32. I've seen a few scattered messages about USB and NTFS mounting issues, but it appears to be an isolated problem. Anybody else having this issue? If so, are there any workarounds? I'd hate to have to revert back to Snow Leopard just to use my thumb drives.

Try to use the disk utility an format one of your Thumb Drive, and see if it can mount.

External Hard drive and dmg files not mounting

External Hard drive and dmg files suddenly not mounting. Im running Mavericks on 27" iMac. Anyone have a fix or has anyone else suddenly had this problem? There was a Mavericks update a few weeks ago, but things were fine until today. This is weird. Ive checked in disk utility and can see one of my two external HD's, the one that I back up. But not even this will mount. Ive tried repairing HD thinking it was damaged but now see that all my ext hd's suddenly dont mount. Ive tried several mac restarts.

Solved the problem. My external HD is a WD (My Book Studio). I needed to install updated driver manager and this fixed it:

If you have a WD external HD goto the above link and search for your model and a list of updates will be shown, Yay!!

Win 7 Pro (via Parallels 6), Snow Leopard, and a USB thumb drive

This is probably a simple fix...
When I plug in a thumb drive, Snow Leopard recognizes it. When I tell Parallels to "share" the same thumb drive, Win 7 Pro installs the driver and it recognizes the thumb drive under "Devices." But Win 7 Pro does not "see" the thumb drive under "My Computer."
Is this an issue with Win 7 Pro not recognizing the thumb drive since the drive was formatted under Snow Leopard?

Check to see what format your thumb drive was formatted as...most of the time the format is MS-DOS (FAT32) when purchasing the majority of thumb drive storage...I want to assume at some point you reformatted your thumb drive as Mac OS Extended.
1. Mount thumb drive onto your mac...hilight your thumb drive and choose COMMAND-I.
2. Check the Format field: (type of format).
If your thumb drive ends up being Mac OS Extended...backup all your files onto your desktop, lauch Disk Utility, Choose your thumb drive and format as MS-DOS (FAT). Copy files back to your thumb drive.
You now have yourself a dual format thumb drive that should mount without issue on any mixed Mac/PC/Parallels enviroment.

Problems mounting USB drives

I am having some problems getting USB flash drives to (auto) mount on my system.
In the past, when I plugged in the device (a simple USB flash drive), it showed up in Thunar and I could click on it to mount it. Now nothing shows up in thunar when I plug in the device. dmesg shows the following, so I know the device is being recognized:
usb 2-2: new high speed USB device using ehci_hcd and address 14
but it isn't being assigned to /dev/sd*. fdisk -l also doesn't show the device. lsusb shows the following for the device:
Bus 002 Device 014: ID 0781:b6b7 SanDisk Corp.
I added a udev rule to automount in /media, as per the udev wiki instructions, but that didn't do anything. Installing udisks and udiskie was similarly unhelpful. I tried this with multiple USB drives (which I both confirmed were working on other machines) so it doesn't seem to be a HW problem.
Thanks in advance.

You might try reformatting the usb drive using Disk Utility. Use MacOS Extended(Journaled). That might help.

I want to use my 1TB Seagate Hard drive for time machine and transferring files from Mac to PC.

For about a year I've been using my 1TB external hard drive for only time machine. To be honest, it wasn't until today that I tried to connect my hard drive to a PC and realize it isn't compatible. I read about partitioning the hard drive so that it can work both for time machine and transferring files between pc and mac. I'm not what you would call tech savvy, so I was wondering if I can get some advice on how to do this.
Thanks in advance.

To do it, you have to partition the hard disk, so you will have one partition for Time Machine and another one to store files and use them in a PC and Mac. To create the partition, follow these steps > http://pondini.org/OSX/DU3.html
In order to read and write in the external disk on the PC, you have to select "MS-DOS (FAT)" as "Format". If you choose any other option, the PC won't be able to read your external disk. Apart from that, note that you can't use files bigger than 4 GB with FAT. If you want to use the external disk with files bigger than 4 GB, you have to format your new partition in exFAT, and you have to do it on a PC
