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.

Ubuntu linux machine can not write to connected usb hard drive

Hi, I bought a WRT610N router. I connected my USB drive to it, and it is working fine with my Vista Machine. However, my Ubuntu linux machine can not write to it. It can read it great, but it can not write. If I connect the drive directly to the Ubuntu device, it reads and writes fine.
I've set all the permissiosn and such in the router setup. I didn't need to do anything in Vista. Is there something I need to do in Ubuntu? I'm new to Linux so Imay have missed something.
Thank you.

Create a new admin user and give all permissions oj your router and check if you can write to it on your Ubuntu linux machine...

Can you boot a Mac Pro using a USB Pen Drive?

Hello.
Can you boot a Mac Pro using a USB Pen Drive? OS=Windows or Linux or BSD or MacOS... I know it is bios specific on a PC if the option is available. If this is possible, does anyone have a link to instructions?
Thanks,
Scott

Not to get in to an argument over semantics here, but by saying "Windows should boot if you have installed the requisite Boot Camp drivers," you are implying "that the Boot Camp drivers [are] needed for Windows to boot." I was just clarifying your post so people didn't get confused.
As for booting a Mac Pro off a USB flash drive, if you have been successful in doing so, can you share with me your method? I've tried booting of an OCZ Rally2 4GB flash drive and it's never worked on my Mac Pro. It doesn't show up when I hold option down and if I try to boot through rEFIt, I get an error about my Mac's firmware not supporting USB booting (I have the latest firmware installed, too). I've tried GPT and MBR partitions, both to no avail. Booting off USB hard disk drives is no problem though. And I can boot off this flash drive on a Core Duo iMac.
Any ideas?

GPO: CD and DVD: Deny write access prevents user from using their USB Pen drive, but other users or ok

My Users have secure pen drives that launch a CDROM partition with a secure logon app that decrypts the main USB mass storage element of the pen drive on successful logon. The problem I have is that users who install the usb pen drive cannot then
initialize the CDROM launcher app to input their password to access the mass storage element of the pen drive making it useless.
However, any other user that has the same type of pen drive who then plugs it in to the endpoint that already has the drivers installed is able to access their own pen drive or the other users pen drive (providing the know the password).
So I've isolated the problem being down to the presence of the GPO setting stated above on the Removable Storage Access Policy, and by not having this policy in place when a user installs the pen drive they have no issues, but I can't find a way to clean
up a user who is already broken even if I remove the GPO from that user, delete their local profile so that they logon as a new user (no roaming or other data) and use a variety of utilities such as USBOblivion to clear out the registry and file system of
the USB device and installation. When the original user logs back on and then installs the usb pen drive again they have the same issue, but no other users do. I have the same issue if I try this with an alternative user or admin as the first user after the
'clean up'. Everyone else can use the pen drive except the user that originally installed it when the GPO was in place.
If I move the user to a new endpoint or rebuild their endpoint then they have no problem being the installer of the usb pen drive and then using it since the GPO was removed, so what I need to know is what is it about the USB install and the GPO that
is tattooing in Windows somewhere and how do I remove it?

Hi,
In my opinion, this is probably not Windows GPO problem. To confirm the suppose, you can follow the path below to check GPO settings if there is any change after the software installed.
Computer Configuration\Administrative Templates\System\Removable Storage Access
User Configuration\Administrative Templates\System\Removable Storage Access
These two policy manage system and current user Removable Storage access.
If there is no change with these policy, it would be better to contact the manufacture of the driver for further assistance.

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?

Is it possible to connect a USB pen drive to ipad 3 via and adapter?

Is it possible, via an adapter, to connect and access documents on a USB pen drive on an iPad3?

Technically, you can use the camera connection kit to attach certain USB drives to the iPad. That said, the ONLY thing your iPad will see are photos or movies that are named with 8 characters and located in a DCIM folder.
So technically you can attach a USB, however it does not work for documents, only photos or videos.
There are some wireless drives out there, the Seagate GoFlex and the iDrive and some others, but definitely with the Seagate it's often just that you can read from or pull from the drive, you can't put your document back onto the drive to get it off the iPad.

How to made usb pen drive a recovery tool....?, how to made usb pen drive a recovery tool....?

As I have downloaded your Recovery Assistant tool on Intel base machine now please describe the whole process to make USB pen drive a recovering tool for my Mac Book Pro as it was pre-install a Snow Lapord OS X.

What OS are you trying to make a bootable recovery for?
10.6 is not available for download and I can't see how you have a MacBook Pro with Retina that came with 10.6.8?
You can either make a recovery disk (which boots & then downloads the installer from the App store). clintonfrombirmingham linked instructions for that.
Or you can make a bootable install disk. First you download the OS from the App store & then use a command to image the installer to a USB disk.

10.6 should be on a DVD installer disk which can be copied to a USB disk via another method, ask if you need that.

How to make my 5.5 genaration iPod act as a USB pen Drive?

Hi,
How to make my 30 GB 5.5 genaration iPod act as a USB pen drive? were i just plug in to my Windows XP PC and it opens a window with what the iPod have inside, just like USP pen Drives.
Or this is impossible and in order do somthing like these i must install 1ª some software like iTunes or other 3ª party software?
I mean other 3ª party software, because iTunes take some time to install, and since what i want is to go to i.e my friends house and the more rapdly possible way make my iPod act as an USB pen drive.
If yes wich 3ª party software?

Read over the instructions given here and try this out:
http://docs.info.apple.com/article.html?artnum=61131
In general, you can use an ipod in the same ways that you would use any other external storage drive with a computer. Whether your computer actually pops open a window when the ipod is connected to the computer depends on your settings, but that should be what happens by default on a typical system.

USB pen drive mounts not seen in system.log. Why?

Any idea why USB pen drive mounts are not loogged in system.log? A WD Paasport drive mount shows up in system.log. Any idea why this is the case and how it can tracked/logged?
It would be nice to have a record of any externals that are being mounted on an OS X client by a user.
MacMini Mac OS X (10.4.9)

Ok, that's it. I read a few posts in the "...SuperDrive won't accept my CD.." section. and it seems some people are just swapping optical drives like mad, ready to accept that the kit is crap, and "...oh, well, I sure hope this one works better...".
But one guy had the brains to have a look inside. Turns out dust had accumulated in the drive and on the connectors, and when he cleaned them, and unplugged and replugged them, it worked fine. So that's what I did. Took it out and put it back in. Amazing the stuff I cleared out! I also un- and re-plugged the power cable and the data ribbon at the mutha board and bingo!. We have disk, and I can breathe again.
Recommend to others they pretend they've bought a new drive, do a remove and reinstall and be very fastidious. You may not need a new one after all. I just love it that stuff can still be FIXED!
Thanks to Lou and all of you who share your experiences. It's like my brain is suddenly soooo huge...

Hi Dave,
better USB support is on the roadmap of Sun Ray Software.
CAC card authentication is not a feature of Sun Ray Connector for VMware View Manager 1.1 (the update); The good news is that the planning for the v1.2 has already started to get this in.

HP USB pen drive nor recognized

My macbook pro early 2013 does not recognize my HP USB pen drive v115w, why and how do I fix this?

Thanks. I forgot to tell you: it does work on my other macbook pro mid2010. I can also see it on any windows machine.
I tried formatting it witn NTFS, exFAT and FAT32, but still my newer mac does not recognize it! I tried formatting it using Windows AND Disk Utilities on Mac.

Booting from USB pen drive is *UNGODLY* slow

Being quite sick of floppies, I decided to install Minimax on my USB pen drive, and it worked fine... But things are going very badly with the boot process. You see, GRUB takes 10 seconds to load, the kernel takes over a minute, and the initrd isn't done loading after 5 full minutes... This initrd is 32 MB, and Damn Small Linux, which is 50 MB, can be copied entirely to my machine's RAM in less than 30 seconds. This absurdly low speed makes booting via USB quite unfeasable.
Now I've got the EHCI controller enabled in my BIOS; in fact, what makes this doubly annoying is that USB2 works fine when I'm booted into Arch Linux, with huge files (e.g. Minimax's initrd) getting written in a matter of seconds. Yet it seems that the EHCI controller isn't doing its thing while I'm booting. What's going on here? I'd really like to get my machine up and running again, the sooner the better...
(For what it's worth, my mobo is a Biostar M7VIG 400, if that's any help...)

Can't do that, Minimax puts the whole damn thing in the initrd.
You sure there's nothing I can do about this? No BIOS update that would fix it, or anything? :cry:
You're saying minimax puts the whole system into the initrd? That is so.. crap. Unlike IDE there's like a max 3 or 4 different usb1.1 controllers out there, and I've only seen about 2 usb2.0 controllers out there, so it's soo much more feasible to have it boot up and mount the usb drive.
I mean, that's just lazy compared to most liveCDs which boot and have to load thirty something IDE modules, SCSI modules, USB modules, Firewire modules and now SATA modules to find the CD/DVD drive, whereas the usb only needs uhci-hcd, ohci-hcd, ehci-hcd and usb-storage to cover 95% of usb capable computers out there.
Make you own usb distro based on Arch is the only thing I can suggest. Possibly base it off the Archie scripts.
As for your bios, there might be an update, but thats something you can check, not for everyone to do for you.
