Where should USB flash drive show up in Lion?

I can't see it on the desktop, but if I pull it out, I get an erroe message that I did not eject it first.

Finder > Preferences > General > Show these items on desktop > check "hard disks" and your flash drives should appear when they' connects. This is how it is in Snow Leopard, it may be slightly different in Lion.

Why does my usb flash drive show wrong info?

Hi all, I hope this is a simple question to ask but I have a 1 G flsh drive that I have pretty much filled up with files to transfer to my PC. I have it formatted to FAT32 . I recently erased some files I didn't really need to free up space but when I go to "GET inFO" it still shows as only 4.9mb available even though, by my calculation I deleted about 200mb worth of files to free up space......what gives??

Did you empty the trash after you deleted the files. They may still be there unless you did this. You can use what size to see what all is really there.

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?

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.

After I installed Lion, my MacBook Pro can no longer detect my external hard drives or my USB flash drives. What should I do?

After I installed Lion, my MacBook Pro can no longer detect my external hard drives or my USB flash drives. What should I do?

And me -- My Mac at work running Snow Leopard reads the drive normally. My home Mac (on Lion) can't even find it....
Yet another Leo let-down.....

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.

I tried to export photos from iMac to iPad using a USB flash drive. The photos are on the drive but when I plug it into the iPad, the iPad says the device requires too much power. Any ideas of what type of USB flash drive I should use?

You can transfer photos outside of iTunes. I do it all the time. THat said, i have a 50/50 success rate with them. I'd avoid sandisk and kingston, their bundled software triggers the 'too much power' warning.
I've had mixed luck with lexar, some work, some don't.
I did have good luck with an older 4 gig geek squad one.
Look for drives without software on them, without bright LED lights and I haven't gotten any larger than 4 gig to work, but that may just be me.
For a less troublesome way? h onestly, I use a SD card that I've formatted with the DCIM folder. I've never had one of them trigger the 'too much power' warning. Just make sure they're not SDXC. those don't work.

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 Display

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.

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.

MacBook Pro Doesn't Even Notice USB Flash Drive

I want to get this USB Flash Drive I have to work. It's a Memorex Mini TravelDrive 2GB. It works perfectly fine on a PC, but doesn't do anything on a Mac. I tried formatting it a couple different ways, nothing. It doesn't show up in the Disk Utility. It's like you plug it in and it acts like nothing is there. If I go to about and click System Report, nothing is listed under that USB port, whereas the other port shows my Logitech USB Mouse reciever, like it should. The other one is just blank. Like when there is nothing plugged in. And I tried both USB ports. I just don't get it. I really need to get this thing working. I mean it says it works on Mac, and I don't see why it wouldn't.

Ooops! It would appear that the purportedly v.2-compatible USBv.3 port isn't quite so. Or the flash dongle tethers on the wrong edge of the specs and is disliked by your pride & joy. Sad day.

Follow up question on recovery data on USB flash drive

HP instructions say the 32 GB flash drive should NOT be branded as Windows 8 compatible. I bought a Sandisk 32 GB yesterday for $20 on sale, but it says on the back it is compatible.
Other more/or less expensive flash drives did not address whether compatible with Windows 8.
I have Windows 8.1
Thanks in advance for your help...
This question was solved.
View Solution.

Hi,
If the flash drive is listed as 'Windows 8 compatible' it cannot be used - the reason is because the HP Recovery Media creation software looks for an external device and flash drives marked Win 8 compatible show as internal drives.
In the example below, the 32 Gb usb flash drive 'Dave G' shows as an internal drive which cannot be used, while the usb flash drive 'Removable Disk H' would work.

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.

OS refuses to mount external USB flash drive. Says a piece of OS software is missing.

OS refuses to mount external USB flash drive. Says a piece of OS software is missing. The flash drive (thumb drive) usually lights up but does not go through the flashing on/off that was tyjpical when first inserting it.
I tried an external hard drive and got the same results; that is, no result, as if it wasn't connected. No icon appears on the desktop and no device shows up in the sidebar. It (10.6.8, Mac Pro Duo) had worked perfectly before this, of course.

Hmmmmm,,,,
Disconnected all peripherals. Did a Safe Mode startup and that worked fine. Very limited features, of course.
Started up with the Snow Leopart (10.6.3) disk. Used disk utility to verify permissions and ran disk repair on all three internal HDs. No repairs needed.
Ran Drive Genius and did the same things, as a double-check.
Plugged in the flash drive (thumb drive) and it came up fine (still operating the OS from the Sno-Leop disk).
I wanted to re-start with the disk and bring up the Apple Hardware Test as you suggested. I had lots of kernal panics on a previous machine, a G4 desktop, and has used that at that time (with a 10.2 or 10.4 disk). thought I remembered that you hold the D key down when starting up from the disk and it would open the hardware test, but either I remember wrong or it works different in 10.6 because it was just a normal startup.
How do I get to the Hardware Test on the 10.6 Snow Leopard disk?
Restarted without the disk and the Mac Pro desktop still showed the gray screen with what Apple calls the "prohibitory" sign, the circle with the diagonal line in it.
I decided to load the OS disk onto HD 3 and designate that as the startup disk, which I did and it works fine. The USB flash drive loads properly, opens, etc. just as it should. I haven't yet plugged in the peripherals (scanner, printer, second DVD/CD recorder, tablet, an external drive, or connected to ethernet yet. Will do those one at a time and see if any of them casued a problem.)
Am I right in thinking:
A) HD One might have bad sections. I didn't defrag with Drive Genius (26% fragged) or look for bad blocks, which I'll probably do tonight.
or B) the OS has been slightly corrupted and may need reloading
or C) I have a virus or conflict (though I haven't added anything new lately). I do have the ButtonManager loading problem for Mac. which is talked about on MacRumors site, etc. but the timing of its appearance and this problem don't match.
Apologies for being so wordy; want to get all information that may be helpful. I appreciate your interest.
