How to find USB flash drive in FINDER if it doesn't appear

I inserted USB flash drive in MacBook Air, but cannot find it in FINDER, my operation system is OSX 10.9.4

Does it show in Disk Utility? If so, Finder Preferences may be the problem. Open them and check the settings:
Ciao.

How to use usb flash drive

So i tried to use a usb flash drive to save a word document on my macbook, but i couldnt find the flash drive, or even where to find the usb port. can somebody tell me how to use a usb flash drive on macbooks?

The USB ports are on the left side.
Just plug in the drive, and it should show up on your desktop (or in the Finder - click the happy face icon in your dock). Drag and drop the files into the drive. Or, select the drive as the save location when you pick Save or Save As in Word.
When you're done, drag the drive's icon to the trash (it will change to an eject symbol), or click the little eject symbol next to it's icon in the Finder. You can then safely unplug the drive.

How to mount USB Flash Drive

Hello again Arch-Linux users,
I always search google very hard and for months (off and on) I search for how to mount a USB Flash Drive. Nothing ever work so I give up than try again months latter. I don't want to give up anymore and that is why I join this forum.
Here are some of the code I found on the net. Some of these commands will only re-mount the entire Arch-Linux running system in /mnt/usbstick.
sudo mount -o rw,noauto,async,user,umask=1000 /dev/sda1 /mnt/usbstick
... don't work it only re-mount the entire system
/dev/sda15 /mnt/usbstick vfat user,noauto,unhide 0 0
... don't work... I found nothing inside /mnt/usbstick
mount -t vfat -o rw,nosuid,nodev,quiet,shortname=mixed,uid=1001,gid=100,umask=077,iocharset=utf8 /dev/sda1 /mnt/usbstick
... don't work... here is the error i get:
mount: /dev/sda1 already mounted or /mnt/usbstick busy
mount: according to mtab, /dev/sda1 is mounted on /
It strange that most USB mount commands use the operating system partition itself- example: /dev/sda1 as the device for USB device, while others use /dev/cdrom for cd - /dev/dvd for dvd and /dev/fd0 for floppy.
Could someone post the code that will easily mount a usb device under Arch_Linux.
I'm using Arch-Linux core-64 (08-2009)
Thanks in advance

Thanks fsckd,
I needed a rapid reply because I been wasting too much time not getting anything done because I needed to get pass this flash-drive thing. I can now have a secure back-up in my pocket on USB to go. Arch-Linux does it better for what I seen while just dd'ing on disk.
...lsusb
Found it

Thanks demian,
sdb is the location for my single hard-drive machine. I saw it before in my list above but I changed it to sda1 because I knew no better. I had no clue it represent a 2nd hard-drive for LINUX if one is not already present.
This did it for me
Thanks again

How to detect USB Flash Drive name in LabVIEW

Hi there
I was looking for how to detect a USB Flash Drive name in Labview
appearently every time i insert USB Flash Drive in a computer, windows assign it a different name
once "J:" and sometimes "M:"
Is there anyway to obtain USB Flash Drive name programmatically in Labview ?
Because in my program an user shouldn't be able to access HDD Drives except his USB Flash Drive (for inserting some file ...)
thank you and excuse me for my poor english

I was able to get the demo.vi to load, but it could not load the other two because there is no block diagram associated with those. I'm not sure why this is. I haven't had any issues with other llbs before.

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.
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.

How to reveal USB flash drive files?

Running on Maverics 10.9.3
I saved my AutoCAD files onto my USB drive a few days ago. Today, I opened my USB again and all of my files are missing. I know they're not deleted because there is used space in the USB drive.
It is a 4gb flash drive and I'm using over 5 mb of it. They're small files, no more then 200 kb each.
ALSO. I downloaded a recovery app online and it SHOWED the missing files in my flash drive...unfortunately it said i had to upgrade/ purchase the full version in order to recover it.
It has my homework in it so I need help.

IT WORKED. Thank you, my homework is found!
I did "Is " ENTER, then dragged the thumb drive to terminal and then it did that poof effect and the usb drive no longer showed in the Devices tab in Finder. I searched the name of my usb drive, found the drive, and the files were there!!
I can see my files, now there's a different situation. I have to search the flash drive name in order to open it. It no longer shows in the Devices area in Finder. How can I show it again?

How to reformat usb flash drive after formatting it in mac

I know this might sound stupid but I used a 16gb kingstonflash drive for a backup for my macbookpro since there are only few to back up and I was thinking I can copy the backup files to an external disk after. With that said, I used the time machine and it said that it would erase everything on the USB. I clicked okand then once the flash drive was "made compatible", it started to backupbut the total file is 34gb so I can't use the flash drive as back up.
I tried reformatting the flash drive, but the total free space is 198mb and even if I removed the partition or erase ( I see a hitachiand kingstonpartition when I looked at the disk utility) it never goes back to the 16gb. I checked it with windows and the USB space is also 198mb out of 198mb (free space) I don't know where the 15.9gbwent.
Any help is greatly appreciated.

Them do it on a Mac with Disk Utility.
On Windows you might have to first delete all the partitions before you can select Convert to MBR.
But try it on OS X.
Open Disk Utility with the drive connected and select the Top name of that drive in the left most area of the window.
Then in the Partition Layout drop down select 1 Partition. Then the Options... button will become active, select that button.
Select Master Boot Record and click OK. The format should already be MS-DOS (FAT) but if it isn't select that. You can give it a name or not. Then Click the APPLY button.

How to clear usb flash drive

Just would like to clear flash drive (usb) so I can use it again. Why does apple make it so hard to do, on my HP the erase message always came up. Please help, Thanks

It's not so hard, but you must adapt to the way of do that on OS X. To erase any disk:
1. Open Disk Utility (in Utilities folder) and choose the disk you want to erase (in your case, the USB drive) in the sidebar.
2. Go to Erase tab, choose the format you want to use with the USB drive and press Erase

How do I browse & play .mp3 files from a USB flash drive using Labview 8.0?

I'm a tester & want to test USB flash drives connected to PC.
I want to browse the file system & playback the audio files, .jpeg files etc in the USB drive. I've Labview 8.0. When I searched for some examples or VIs which can detect the USB flash drive, couldn't find any. So if you could point me in the right direction, I can find a solution to my problem.
Thanks.
Solved!
Go to Solution.

You probably won't find specific examples for this. A USB flash drive is mounted by the OS and appears as a new memory storage device to all software on the PC, including LabVIEW. You can certainly write a LabVIEW program to open files on the stick and play/run them but I would create a VI that wrote files to the stick and then read them back and checked them for bit-level errors. Keep in mind that your OS might be doing parity checking under the hood which would make your test rather meaningless.
BTW, testing memory by looking at pics or listening to MP3s would be useless of course. A human can't see or hear bit-level errors in a high bandwidth data stream.
Using LabVIEW: 7.1.1, 8.5.1 & 2013

Problem Stopping Finder Copy to USB Flash Drive

I was attempting to copy my Pictures folder (about 4.5 GB) to a USB flash drive. It seemed to copy OK until it got about a third of the way through and then stalled. I selected the stop copy on the dialog box but nothing happened and the copy dialog box just became grayed out. I could not eject the flash drive either. When I used the Command-Option-Escape key combination, I was given the option to relaunch the Finder, which I selected but then was just left without the ability to use the Finder at all. I resorted to pressing the power button to shutdown and then restarted and was able to eject the flash drive.
Is the Finder capable of copying a file of this size? What causes Finder to freeze up on a copy operation? How else could I have stopped the Finder copying process once it hung? Thanks.
Regards,
Steve M.

Before trying the Safe Boot, I tried a different experiment. I just tried using the Finder to Duplicate the Pictures folder. It duplicated fine without problems. Then I repaired permissions on my internal disk and did a repair disk on my flash drive (no repairs needed). Then I tried to copy my Pictures folder to my flash drive again and the process hung right about at 600 MB of data transferred.
I know I'm using USB 1 and that's a slow connection. My previous flash drive was only a 1 GB so I typically never transferred very large files before. I think Finder is working as it should and that I am bumping up against some problem with USB 1 transfers or with the flash drive itself (it is formatted Mac OS extended). I'm using a powered USB hub to plug the drive into and I know the hub is working fine. I guess I could try connecting directly to a USB port on the iMac to see if that helps.

Steve M.

Finder stall after wake from sleep w/USB flash drive mounted

Has anyone else experienced this? iMac works flawlessly while USB flash drive is mounted UNTIL iMac sleeps. Then as soon as the iMac wakes from sleep the finder is non-responsive (perpetually spinning beach ball) and other apps slow to a crawl and become non-responsive as well if they need the finder (i.e. to save, etc.). This only happens when the USB flash drive is mounted.
Trying to force quit (relaunch) the Finder does not work, I always have to perform a hard restart.
I have an external FireWire hard drive that works beautifully and does not cause these same symptoms.
Any ideas?

umm.. don't let the computer go to sleep with your jump drive connected? The mac will usually take a few seconds to get his gear together after waking up from a sleep sounds like he is having to gather additional things since the jump drive is in there. I don't have a REAL solution except don't let Mr. Mac sleep with the jump inserted....

As a new MacBook user I plug in my USB Flash Drive but don't know how to access its contents. Please help. Thanks.

as a new MacBook user, when inserting my USB Flash Drive, I do not know how to access its contents. Please help. Thanks.

Open a new Finder window, Finder > File > New Finder Window, and it should appear on the left under Devices.
If you don't see it there, or to get it to show up on the Desktop: Finder > Preferences... General tab, check External disks to have it show on the Desktop, Or Sidebar tab, check External disks under DEVICES.
