Verbatim USB Flash Drive Stops Being Recognized

All of a sudden the other day, my Verbatim USB flash drive just stopped being recognized... it had been mounted, a TM backup made to it when all of a sudden I got an error stating that it had been improperly removed... it was like I had yanked it from the USB port...
I tried unplugging it, reconnecting, rebooting, moving it to another computer... no luck... it doesn't even show up in Disk Utility
Verbatim has agreed to replace it under warranty but I'm wondering if there's anyway that I can mount it again to retrieve the TM backups...
Any thoughts?
Many thanks!

My Verbatim 32G flash drive appears on the left, but it will not allow me to repair it, mount, or eject it. It will not show up in Computer like it normally does. I have tried restarting it, turning it off, and doing Command+Option+r+p, which did not work. I believe I caused this problem by accidenlty ejecting the flash drive before safely removing it. How could I make it appear on the Computer again?

USB flash drive not being recognized as a startup disk?

Hi everyone, I've been searching for similar questions but haven't found one that exactly matches my experience. So, I'm going to try and explain my issue in hopes that others may be able to help.
I'm trying to create a bootable flash drive from which I can install lion, and eventually Mountain Lion when it is released onto my main hard drive. My main reason for doing this is to have a way that I can perform a clean install of the operating system. Yes, I know I am old fashioned, but sometimes I prefer clean operating system installs rather than upgrading. In any case, I have downloaded the lion setup file from the Mac app store (Install Mac OS X Lion.app) and am following the directions given on this page to do this procedure. These directions are consistent with directions found on various other sources online. Having this file saved to my hard drive, I was able to find and extract the disk image file from the package InstallESD.dmg to another folder. Once extracted, I plugged in my flash drive and attempted to use disk utility to restore the disk image to my flash drive. I selected the dmg file as my source and the flash drive as the destination. I then clicked restore and was warned that all data on the flash drive would be erased while the disk image was restored to my flash drive. I was prepared for this, so I allowed the process to continue, and it appeared to proceed with no problem. When disk utility was finished, I did a quick look at my flash drive using finder and confirmed that it did in fact appear to contain a disk image of the .dmg file. Here's where things get interesting however.
When I go to system preferences and choose startup disk, my flash drive is not listed as an optional disk from which to boot, only my hard drive ("macintosh HD"). When I restart and hold down the option key, my flash drive is not listed as a startup disk either. I know that the non-intel based macs are not capable of booting from USB, but this is certainly not my issue as I have an intel macbook pro, mid 2009 model. My flash drive is about 4 or 5 years old; it is a PNY Technologies Attaché 16 gb flash drive. I have no trouble viewing and transferring files to and from the flash drive, the only issue is that my computer seems to refuse to recognize it as a startup disk. Are there certain flash drives which do not support booting? This would normally seem more like a computer issue rather than a flash drive issue, but most people seem to have no problem doing what I'm trying to do. Unfortunately I do not have another flash drive with which to test this, and I didn't really feel like buying another flash drive just to test this out if in fact this is not a flash drive issue. I am planning to upgrade to the macbook pro retina soon which of course does not have an optical drive, which is one of the reasons I would like to get this working. Can anyone think of something else I can try? Is it more likely an issue with the macbook pro or the flash drive?
Thanks in advance for any thoughts.

The format says Mac OS Extended. All of the settings were set during the disk image restore process. Even if I format the flash drive as extended journaled or some other format, all of these settings are reverted when I do the restore from the disk image. I will just copy all of the information that disk utility has so that you can see it.
Mount Point : /Volumes/Mac OS X Install ESD Capacity : 16.11 GB (16,106,110,976 Bytes) Format : Mac OS Extended Available : 12.3 GB (12,303,499,264 Bytes) Owners Enabled : Yes Used : 3.8 GB (3,802,611,712 Bytes) Number of Folders : 128 Number of Files : 876

For some reason, my USB flash drive is being recognized as an external hard drive, is there any way to fix this?

I think I used Disk Utility on this flash drive before and know it won't show that it's a flash drive, my other flash drives still show up as flash drives so is there anyway to fix this? I'm on Mac OS X 10.9.3.

A workaround.
If you would like to change the drive icon:
- Under Finder right click on a flash drive and choose " Get Info "
- click on the disk icon at the top, from the desktop menu select Edit -> Copy
- Under Finder right click on the problematic volume and choose " Get Info "
- click on the disk icon at the top, from the desktop menu select Edit -> Paste

Installed itunes - usb flash drive no longer recognized

hi,
I installed itunes, loaded up the ipod with music, and now my computer will no longer read the files off my usb flash drive. the computer sees the "mass storage device" when I plug my drive in, but the volume/files are not coming up.
any suggestions?
thank you!

Are you sure the files are still on your Flash drive.? Can you locate them in a folder on you flash drive just by going to the iTunes\iTunes Music folder and viewing the array of folders? If they are there, go back to the iTunes icon on the desktop, bring up the list of tunes, highlight them all, delete them, and go back to the Flash drive, highlight all the folders, drag them over to your blank iTunes screen and drop them. You won't get any indication anything is happening right away but they are reloading. For some reason iTunes cannot update itself with the correct pathways.
Hope this helps, Dave.

Upgrade to 10.4.7, now USB flash drive isn't recognized

I upgraded to 10.4.7 the other night, but the installation was interrupted. Apple Support got the machine up and running by doing a safe boot and removing some corrupted start up files.
Problem is that my USB memory key isn't recognized. It works fine in my iBook, but not in the iMac.
It appears in the System Profiler as a "Flash Disk", but does not appear in the Disk Utility.
iMac Intel 20" Mac OS X (10.4.6) Upgraded to 10.4.7

I have an expanded problem now -- I still can't get the system to recognize the flash drives, and it won't recognize my digital camera, either. Oddly, it starts iPhoto, but it doesn't see the camera.
I've tried all the erasing tips with the flash drives, but they didn't work.
There is nothing in either System Profiler or Disk Utility identifying the camera.
Otherwise, the system runs great. And the keyboard and mouse work fine.
Any ideas?

USB 2.0 stopped being recognized by USB 3.0 port

Hey all,
Two days ago, I was syncing my iPod Classic (USB 2.0) with iTunes and I also had my USB 2.0 Time Machine drive plugged in (I do not think it was backing up at the time), both of these devices were plugged into the USB 3.0 ports on my 15" MacBook Pro (Mid 2012). All of a sudden, my MacBook informs me that both devices were disconnected. For the next 30 minutes, these devices connected and disconnected sporadically. I tried restarting my MacBook multiple times, I reset the PRAM multiple times, I reset the SMC multiple times, I booted into Windows 7 (I use Boot Camp) and both devices show up as unrecognized. They do not show up at all on the OS X (10.10.2) side of my computer. What's strange though, is that all USB 3.0 devices work perfectly. I tried an old USB 2.0 flash drive, didn't work.
Anyone have any thoughts? I have searched Google and these forums for the last two days to no avail.

To plug a 2.0 into a 3.0 you are using an adapter? Is this where the problem is? Even with the old flash drive? or did you also try using the 2.0 ports on your MBP? The adapter could be bad or the cables for your external devises. You did the steps you need to do to correct the problem. Other then that it would be a hardware problem. And you would need to take it to an apple store to be checked out.

External USB hard drive not being recognized

Hello! I'm sure this has been posted before, but excuse my naivety with this sort of thing...
I have a mac mini 10.5.6 (1.83 GHz Intel Core 2 Duo) and I run the Time Machine function to an external usb hard drive. The hard drive worked fine (plugged into the usb port on an older keyboard), but I went out and bought a new aluminum apple keyboard (because they look so cool ^_^ ) - I plugged the external usb drive into the keyboard and it wasn't recognized, so I tried plugging the external drive directly into the mac mini, but it is still not recognized. It is not showing up in Disk Utility or in System Profiler
Help? I'd hate to have to give up this fancy keyboard...
Thank you!
Dr. E

I believe I had my external drive plugged into the (old) keyboard because with the old mac that I had didn't have a free usb port for it - so when I got the mini I just plugged things back in where they were. But I have always had the Time Machine back up to this drive (connected to the keyboard) though it has been slow (another reason I thought the new keyboard was a good idea).
I tried restarting the computer without the alu keyboard plugged in, but same problem of no drive showing up.
Here is what System Profiler has to say about my drive:

I don't know the brand or model as it has 'always' been in the case that in which it currently resides and I didn't physically buy the thing :\ I do know that no software was installed with the drive as I assumed that when I put all the old info from the original mac to the mini that it was the sort of thing that would carry over.
Sorry I'm not terribly helpful - Thank you!

Super Talent 8 GB USB Pico drive not being recognized on my iMac.

Hello, I recently bought a Super Talent 8 GB usb drive. I tried inserting it into my iMac (previous generation, in between the first and latest version) and it doesn't show up on the desktop. The packaging says it is Mac compatible and USB 1.1 and 2.0 compatible. I tried using my keyboard's ports and my main ports on the back of the computer and it still doesn't show up. Does anybody that owns this same drive know any tips?

One thing to try is doing a SMC and PRAM reset on your iMac. Just in case here are instructions on how to do that, let us know what happens when you insert the flash drive after doing the reset.
*SMC & PRAM Resets*
To do these:
1. Turn off your iMac and unplug everything from it for 30 seconds.
2. Plug in the power cord, keyboard and mouse only.
3. Press the power button and immediately hold down the Option, Command, P & R keys until you hear the second gong then release the keys. Your machine will start up normally, then check for the issues you are having.
Regards,
Roger

Flash drive not being recognized

My 128 Patriot Flash drive is not seen as potential scratch disk by CS5. I reformatted it as exFAT and then as NTFS but still not seen by CS5.
Thanks, CMA

Check your device manager. I'm sure it's listed as a removable drive and PS only uses fixed drives for swap. If the device offers a special system driver, install it and it may be assigned as a fixed drive, if not, then there's jsut no way to coax PS into using it.

USB Hard Drive not being recognized

I have a SATA hard drive in a USB enclosure. It suddenly stopped functioning, and I took it into a shop. They said it showed up outside the enclosure, but had no files. And that since it was formatted for Mac (They were using a PC) that the enclosure was most likely the issue. I bought a new one and put the hard drive in it. It didn't show up on the first try, so I double checked the connections, and one was loose. When fixed, it showed up right away. But now it won't show up. All connections are secure, and I've reset my PRAM.

Got a sata<->usb connector, and replaced the wiring of my enclosure with the connector. All is well.

HELP! WD Passport External Drive stopped being recognized by my Mac

This happened out of the blue. It worked fine for 2 years. No problems. Then today when I plug it into my Mac, I hear it spin for about a minute but my Mac won't recognize it. The drive doesn't show up at all, anywhere, including the Disc Utility. The external drive also appears to be in fine working condition --- I have never seen it overheat, and I have never heard any noises coming form it.
The WD Passport External Drive uses a Firewire 800 port, and my Mac notebook is a late 2011 model, and it is running OS X 10.9.5.
The only thing that was oddly coincidental was that I noticed this after I installed an update for iTunes that looked like it involved more than just iTunes (I saw something about a "Safari patch" and other stuff in the bundle too). I'm thinking this was just a coincidence though, and I'm not even sure the external HD wasn't working even before that, but who knows.
Anyone have any ideas???

Some more information...
So I was able to test the external HD using the USB port (instead of the Firewire port), and also tested it on a separate computer, and I always experienced the same problem. The external HD starts trying to spin and connect to my Mac, but after trying unsuccessfully to do so after about 20 seconds it gives up and stops/powers-down.
Since I've tested it using different ports, different connecting wires, and different computers, I'm thinking chances are the problem is with the hardware of the external HD itself (i.e. worst case scenario).
Before shipping my external HD off to get repaired or to get the data recovered, can anyone think of any reason why it would be a software issue? I read something about updating the "firmware" but I have no idea what that is. I guess I'm still holding out hope that the drive isn't fried because when I plug it in it does try to spin and start up instead of just remaining dead.
Any ideas at all are welcome at this point.
Thanks

External USB Hard Drives Not being recognized since recently.

Some quick facts:
Using early-2011 MacBook Pro, 15"
Two HD's worked fine recently (around before upgrade to Mavericks):
1 Lacie Neil Poulton 1TB Disk
1 Western Digital MyBook 500GB Disk
BOTH were formatted to Mac OS Journaled since day 1, so NO bloatware/manufacturer software. Purely storage.
The 2 drives are connected via a powered USB hub, but connecting it directly doesn't help. (strangely, the keyboard and mouse attached via USB hub work fine)
Tested with 7 different USB drives to test– none of them work
The 2 drives actually show up in the System Profiler, but not in Disk Utility.
Both Hard Drives work on my 2012 Macbook Air 13" (running on Mountain Lion) absolutely fine. Tried the 7 USB drives– they all work as well.
Tried SMC reset. Briefly detected the drives, but once I put it to sleep and turned it back on, it stopped detecting it again.
Help!!!!!

Yes, youre having a problem with WD software and firmware, this has been a point of much discussion with WD software and Mavericks , and affecting drives OTHER THAN WD, via their software
you can read about it here, and ask WD about their removal software

http://www.tuaw.com/2013/11/27/western-digital-smartware-software-update-address es-bug/
From WD:
You can now download the WD Software Uninstaller. This utility will remove Mac WD SmartWare and WD Drive Manager software. You can find the uninstaller under any of the Mac Drive Downloads sections such as the My Book Studio below.

My external hard drive stopped being recognized by Time Machine. Any fix? being recognized

As the title of the question suggests, this happened suddenly, after months of trouble-free integration with Time Machine. If I bring up the disk utility it recognizes the drive, but won't perform any repair or other operations on it. It indicates the disk is unformatted.
Any way to repair/re-format this back-up drive, or should I just toss it and buy another one?

Sounds like it either has, or is about to die.
If you don't need anything off the old drive, then yes, replace it immediately with something a little more reolaable. I use WD Caviar Black personally. But anything that has a known low failure rate.

Disk Utility – Force Mount Disk

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.
