USB Flash Drive no longer shows on Desktop, it does appear in disk utility. I recently upgraded to 10.8 from 10.6 on both iMac and Macbook and the drive does the same on both.
I updated my Snow Leopard to Mountain Lion and have had only minor issues with some software but I plugged in a USB flash drive and went to format it, it now appears only in disk utility and not on the desktop. I have tried restarting and reseting with the drive in and out, I tried it into my macbook and it does exactly the same there. I can't do anything in Disk Utility so can't access it in any way and it says errors if I try to eject it from DU. I'm not normally stumped but I can't figure this out at all. I'm hoping that someone here could give me an idea that I haven't thought of as it's a large Flash Drive and I really would like to keep using it.
Thanks in advance for any help anyone can offer.
If it has the same (bad) behavior on two different systems then there is a very good chance that the drive is toast.
BTW you'll get better response to your questions if the question actually reflects the problem you are having. In this case it would have been better to say you couldn't access the drive rather then that it doesn't show on the desktop.

USB Drive not showing up at all, not appearing in disk utility either
Hi, I am having a problem getting my USB drives to show up at all, namely my iPhone. When I plug my iPhone in, iTunes recongizes it, but I am unable to get it to appear in Finder, Desktop, or Disk Utility. I tried it on a Windows PC and it works perfectly fine. I am also having issues with USB thumb drives. However, my western digital external HD works fine.
Very strange problem, anyone have any solutions?Now don't do that.
My only other thoughts on this was that there is something wrong with the cable or jack in your macbook. You said the iphone mounted in a windows pc. So it looks like the cable is ok. That may mean the jack has problems. On the other hand you also say plugging in the WD external works through that jack. So the cable and jack look ok. So much for that thought.
I also would suggest a pram reset but I doubt that would have any affect. Or is that why you did when you said you "flashed" pram? -

[SOLVED]USB flash drive no longer showing up in /dev
My USB flash drives are no longer showing up in /dev. I also don't see them in /dev/disks/... either. Dmesg outputs:

Any ideas on where to start?

USB flash drive not recognized on desktop or disk utility
I see a number of similar threads to this but nothing solves this problem. Any help will be greatly appreciated as I am about to go crazy!
I have 3 USB thumb drives that all worked 2 days ago - now only one does. I have tried all drives in multiple ports and the same result. I have restarted the iMac (2009 Yosemite) a number of times and the same result.
This came about attempting to create bootable USBs with each of these. I was struggling with the process on my mac so took 2 (brand new 16GB PNYs) to a PC created the live boot USBs and they booted fine on the PC (knowing this wouldn't boot my mac). I did however plug them into my mac and they were recognized. I finally found success creating a Ubuntu live boot with my old USB. With that success I wanted to try with one of the new USBs on the mac.
Here is what I did:
1. Using Disk Utility - Reformatted the drive 1 partition MS Dos FAT 32
2. In Terminal unmounted the drive and ran a dd command to copy the linux .img file successfully
3. Box came up saying drive not recognized and selected to ignore (this happened on my old one that still works also)
4. Ejected drive from terminal
5 Restarted mac and attempted to boot from USB without success.
After this the 2 new USBs were no longer recognized in any usb port while the other still is. They do not show on the desktop nor in Disk Utility. I checked them on the PC and they are still both recognized and showing the FAT 32 format.
Help please!Thank you for the reply. I found some time to go through this process a number of times without success
Any other suggestions? -
Usb flash drive wont mount on desktop
my usb flash drive no longer mounts on the desktop or shows up in disk utility.When i plugged it in the green led did a series of flashes with 3 intervals and the cursor froze.Unplugging it brings the computer back to normal.It works fine on a powerbook and on a pc at work.I re-formated the drive on the pc using fat32 and it works fine.(dragged files out first and back again after re-format).Now when i bring it home the green light flashes continuous and does not affect the computer in any way but it still wont show on desktop or in disk utility?.

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. -
Has anyone else found solution to Apple devices not 'seeing' each other on Home Share? I have a Macbook Air (new Nov'12) and Apple TV (new Dec'12). Software updated on both. Both are logged into the same Wifi network and the same iTunes account (I can view movies purchased from iTunes on my AppleTV). Home Sharing shows 'ON' for both devices. BUT...AppleTV shows no computers... and ... Itunes sidebar does not have a 'Shared' area at all. Help please as without this functionality, my Apple TV only provides portal to purchased (i.e. Netflix,...) content which I can get from Wii or Xbox.
I have already tried the following without success:
1. Homeshare DID work the first day after I setup Apple TV... but the next day it has not worked since then.
2. Powered off 30 sec then re-started (Apple TV & Macbook & iTunes login)
3. Checked Firewall settings per Home Sharing troubleshooting guide (correct settings)
4. Turning on Photostream in iPhoto and selecting iPhoto within iTunes and then checking to see if Photostream shows anything on AppleTV (it shows 'on' for my iTunes account but 'Zero' pictures found ... despite the >3,000 pictures showing avail in iTunes).
I also have 'Remote" app on my iPhone 4, with Home Sharing turned on (same Wifi network)... it has a very similar message as the Apple TV and same result that despite all devices having HomeShare 'on' they cannot see each other: "Remote will automatically find the iTunes libraries and Apple TVs that have Home Sharing turned on using the account xxxx (it lists my correct itunes account name)."I solved this by reset of the Wifi (unplug cable and power to both modem and wifi ... wait 60 sec ... plug in modem cable and power ... plug in wifi power and LAN to modem ... restart AppleTV and Mac ... Turn Home Share 'OFF' in iTunes then back "ON" ... it took ~60 sec for the AppleTV to pick up my Mac in computers.

if i use a usb flash drive which is mac os and windows compatible can i use it to copy files from the mac to a windows machine. i have to do some training abroad and wnat to take the files on a usb from the mac but they will only have a windows operating system available to me.
Generally, it's not the flash drive that makes it compatible, but the formatting used on it. In Disk Utility on a Mac, the format is called MS-DOS (FAT). In Windows, I believe it is called FAT32.
A USB flash drive formatted that way should be readable and writable on both Mac OS X and Windows. But you may want to try a "trial run" before relying on it for the trip. -

Trying to format a new USB flash drive so it will work on both a Mac and PC
I have a brand new Sandisk USB flash drive that I am trying to copy movie files onto from my Mac's hard drive. For some reason I can copy one of the movie files but not the other, even though they are both Quicktime (.mov) files. In doing some research, it seems the one file will not copy/paste likely because it is over 4 GB in size and the FAT32 filing system on the USB drive prevents files in excess of this size to be copied and pasted.
My question to anyone who can help me is: How can I get files over 4 GB onto and off of this USB drive AND be able to use it for both Mac and PC computers?
Thanks for any advice.
ShaunIf I format the USB stick on my Mac as exFAT, will my client who´s most likely using a PC be able to screen it tomorrow morning...??
exFAT would only be an issue if they were running a version of Windows older than XP. If it is XP, they would need to install the free exFAT update before being able to access the drive. -
Combine USB flash drives and other USB storage to show up as one?
Hi,
Is it possible to combine USB flash drives or USB hard drives so when you plug two or more in, it will show up as one? Kind of the opposite of partitioning. Preferably using disk utility.
Thanks!Hi gpd2paul4;
Possible probably. Should you do it? Probably not.
You would be using software RAID which would run only as fast as the slowest item in the RAID array. The USB flash drive would make the RAID array abysmally slow at best.

"Removable Disk" shows up in Windows 7 even when USB Flash drive isn't there
I have a new windoz 7 computer, a couple of new sandisk cruzer 16bg flash drives. I removed the flash drives a couple of times without doing the "eject" thing. I never had a problem with your flashdrives on my xp machines. I know I was a bad boy, I just pulled the usb flash drive out. When I go to my computer folder it shows me my hard drives and its shows 5 Devices with Removable Storage ....one of which is the DVD RW Drive and 4 Removable Disk which are or were times when I plugged in my usb flash drive. They show 0 bytes, nothing is in any of the "Removable Disk" instances and I cannot remove them. I tried to delete, cut and I tried to eject but the Removable Disk icon stays there. How can I get rid of these safely, I tried rebooting a couple of times, they show up even without any usb devices plugged in. Thanks in advance Scott
I had this same problem. It turns out to be easy to resolve:Open the Windows 7 "Start" Menu, on the right shoose computer, in the new window that opens choose System Properties from the choices across the top of the window, now on the left side of the window choose Device Manager. In Device Manager expand the "Disk Drives" entry. You should see a listing of your hard disk drives and you'll also see "removable disk drives" with some additional idnetifying information. Select the offending entry and then right click and select "Uninstall" click "Okay" and the entry will be gone. Just be sure you're not uninstalling one of your hard disks. That's all there is to it. To prevent this issue in the future always "eject" the SD drives/sticks before you remove them. I hope this helps.

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:
Name : SKYMEDI USB Drive Media
Type : Disk
Disk Identifier : disk1
Media Name : SKYMEDI USB Drive Media
Media Type : Generic
Connection Bus : USB
Connection Type : External
USB Serial Number : 03
Writable : Yes
Ejectable : Yes
Mac OS 9 Drivers Installed : No
Location : External
Total Capacity : 2.0 TB (2,199,023,255,552 Bytes)
S.M.A.R.T. Status : Not Supported
Disk Number : 1
Partition Number : 0
Selecting HFS+ (journaled or not) or MS-DOS then clicking Erase gives me a spinning beach ball requiring me to Force Quit DU.
My config: G5 DP 2.0, 1 GB ram, 10.4.6
Any thoughts?
G5B DP2.0 & iBook366SE Mac OS X (10.4.6) Alu 20-in Displayhey 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.
