Invisible pen drive

Hi all,
I have a 2Gb kingston pen drive that used to be seen normally by my imac. But something happened after one operation of file transfer: the transfer window froze, the transfer stopped and now my pen drive is no longer recognized by the computer, no matter what I do.
Can anyone help me to find a way to put glasses on my imac?
thanks!

I did what you told and the window of usb info remain blank, while the system was looking for something. Then I pulled out the drive and all the information popped up:
DataTraveler 2.0:
Capacity: 1.89GB
Removable media: Yes
Detachable drive: yes
BSD name: disk1
Version: 2.00
Bus power (mA): 100

Any suggestion?
By the way, thank you so much for the kindness...

Pen-drive recovery from bitlocker

Hello , i secured my pen-drive with bit-locker and i forgot my password and lost my recovery key . I have a lot of important files in there , please help me recover it.

Hi,
Like Aaron said, sorry, but unless you remember your password, your data is unfortunately lost.
The entire point of encrypting your data is that no one but the holder of the password has access. If there where an easy way to bypass the encryption, there would not be much point to it.

Can I transfer data from a PC to a Mac mini from a USB pen drive?

I currently use a PC using windows vista, I would like to purchase a Mac mini and need to know if it is possible to transfer data from the intuit quickbooks program to the Mac mini? I have the data backed up on a USB pen drive. I wasn't sure if the saved data would be compatible with the Mac mini from the windows pc.

I know this is a common question - but is there a way to connect a USB pen drive to the iPad? (See details)

Basically, I just bought a Nexus 7 after growing impatient waiting for the iPad mini. But the Nexus has a fault, and I'm taking it back next week. I'm wondering whether to get my money back, or just get another - because it's a pretty good device!
My major big thing about it, is that I can plug a USB pen drive into it with a OTG cable and either just stream pictures, documents or movies - or save them to the Nexus for viewing without a dangly wire to annoy me. It's great! However, being an Apple fan - an iPad mini (if it comes out!) would be simpler, because it would sync to iCloud etc. whereas obviously my Nexus 7 doesn't do this at all. The only iCloud factor I can access is my mail. Which isn't a problem, just a prefference.
So, with current iPads - is there a way, without jailbraking the device, to say stream movies to the device through a USB pen drive/external HDD, and save them to the iPad?
I've seen ways on YouTube but thought it was best to ask here.
If this was possible, I'd swap the Nexus for the iPad mini straight away - the Nexus 7 is fantastic! No problem with it, if it wasn't for iCloud, I'd keep that.
Oh, and as a closing question on the iPad mini/Apple Maps - the Nexus 7 lets you download offline maps, and also you have a GPS which is used even when not on wifi - do you think this will be likely on an iPad mini? I can't see it myself.
It's a sad day for me, when I start to think Google may still have the upperhand on 7" tablets, even after the iPad mini is released. I might even wait for the Second generation (if it exists!) - just because I for some reason never like first generation things from Apple.
But anyway, that's a lot of questions and info!
Thanks in advance!

Ok, fair enough. But since Job's death - Apple's control on leaks has been terrible. I got the new iPhone, and I like it - but it hasn't made nearly as big as an impression as previous ones. Because of the vast ammount of leaks. With the iPad mini leaks, it's 99% sure to come out next week.
Apple uses many manufacturers and it's massive also websites prefer to report on Apple whether true or false because it brings more hits.
Amd by "others" I meant other people on iPads - not other devices/manufacturers. It's possible to do so, I just want to know how. I honestly don't think we'll ever be in a Post-PC era until all tablets allow us to use USB in the way computers do.
No, USB is not the future, you missed the memo about cloud and wireless computing?

Folders are missing in windows 8.1 after inserting pen drive.

I have windows 8.1 in my laptop.i had some files in the drive c:\users\my profile\downloads folder and also in e:\downloads folder.I connected pen drive to my laptop.scanned with anti virus no virus found.My anti virus signatures are updated till date.i
disabled my live account login account in my laptop and created one local account login.Logged off and logged in.Now i cant access folder "c:\users\my profile\downloads folder" access denied.second e:\downloads folder missing. i enabled hidden files
view in tools explorer options still not working.what may be the problem

Hi,
Does the folder c:\users\my profile\downloads folder belongs to your new local accout or the original live account?
If it is the original live account, then I would suggest you access\look for the files with your original live acocunt, after you login with that account, copy the files to C:\Users\Public folder, folders\files under the public folder will be accessable
to other user accounts in system.

I just tried to copy a folder to a pen drive from my mac. It transferred fine. I then ejected the pen drive then pulled it out. When I pulled it out it said it had not ejected correctly despite me just Doing this. The folder is now missing from both! Help

I just copied a folder from my desktop to my pen drive. It transferred fine. I then ejected the pen drive then pulled it out. On doing so it said it had not been ejected properly!!!!! The folder is now missing from my computer and the pen drive. Pulling my hair out please help!

When youi say Eject, the RAM copy of the Directory is written back to the drive. On a pen drive, this can take several seconds.
If you get too excited and don't wait those few seconds, the directory write will be incomplete, and the drive will lose its integrity or lose files or both.

Have you tried running dosfsck on the device? Of course, be sure that you unmount the usb drive and verify the dev file of the relevant partition.
Something like:
dosfsck /dev/sdb1 <----replace with correct dev file!!
to see what the problem is and then
dosfsck -a /dev/sdb1
Of course, I would strongly encourage you to backup all data on the drive first.

Running authroware from pen drive

A user wants to run authorware from a pen drive.
I had created a folder for the user, which contains published
authorware with runtime exe.
I've tested this on my pen drive it seems to work ok, by
copying the folder onto the pen drive. He says he did the same.
This users gets this error: "js32.dll is not a valid image
for windows"
He's translated this from spanish, so he must be running this
on spanish windows version (if this makes any difference)
Thanks in advance
Jon

OBP should place the js32.dll file in the published directory
automatically. It is required. OBP should also place the
dvd.dll in the
published directory. That one is not required. I find myself
deleting it
often.
If you're not using OBP, or OBP is not including that file,
yes - you
must then include that file on the same level as the
.exe/runtime manually.
If the thumbdrive has that file but it's not being found,
likely it's
corrupt (?). Thumbdrives are cool but not super-reliable yet
(IME).

Using pen drive from pc

I have a pen drive that I used in my windows pc, and now I am wondering how to convert the information so that my mac can read it?

Have you plugged the pen drive into the Mac yet?
Mac's can read Windows formats, just can't write to NTFS formatted drives.
Drives, partitions, formatting w/Mac's + PC's
Since the Mac can read it, the files can be transfered to the Mac.
Now it's just a matter of the format of the files themselves, and what programs can read/write to these formats.
Some developers make programs for both OS X and Windows operating systems, so it's just a matter of getting the OS X verison.
If there isn't a OS X version, perhaps it can be converted or another program used to use the file or partially in some manner so it can be recontructed.
Some file formats are universal, can be opened in nearly all programs capable. (mp3, .jpg, .text. etc)
So I guess at this point you will need to know the file formats of the files, and what OS X programs can open/use them.
This can be done by looking at the extension on the end of the file name, like myimage.jpg, or myresume.txt, or rockingold.mp3 and finding a program that will pen/use the file format.

Pen drive partition not detected

good evening,
since i formatted my pen drive on windows with fat16/32 the sticks' partition doesn't show up anymore in /dev. there's just a new /dev/sdx and even cfdisk doesn't like the mbr anymore. so i formatted it on linux with mkfs.vfat to fat16/32 (wiped the mbr with dd first) and now windows doesn't like the stick anymore (says the drive isn't formatted) - fortunately might someone say but i'd like to use it on both os'.
this is the fat16 formatted mbr from linux:

so here are my questions:
why does windows give a fuck on standards? (not recognizing standard mbr and ignoring partitiontable offset at 0x1be - no wonder cfdisk goes crazy) and how the heck do i get the stick working again on both os'? any special trick with mkfs.vfat?
thanks in advance.

Thanks for your further replies!
So i tried to format the device with the -I switch and the stick didn't work.. no matter how long i wait, there's no partition initialized at any time. I also got a brandnew stick from a store today and it didn't work from scratch with the delivered mbr - weird..
And according to the 'windows only likes the first partition'-thingie.. ridiculous - i'm currently at a point where nothing surprises me anymore about windows and it's incredible capability of incompatibility.

I also tried to formate it using the gparted tool, it says partition read only
I tried dd command it also says partition is read only file system
