I can only read on my flash drive and it won't let me format it. Please help!

I'm frustrated.

Some flash drives have a failure mode in which they are irreversibly write-locked by the internal controller when it detects a write error. If the drive doesn't have a write-lock switch (most do not) and you can't erase it in Disk Utility, that's almost certainly what has happened. To be sure, test it with another computer, if possible.

  • I have an ipad 2 and I noticed I have over 3000 emails in All Mail. I want to know how can I delete these emails. It looks like you can only do it one at a time. It will take me forever. Please help me.

    You can only delete them one at a time on the iPad. If you have an IMAP email account, go to your email in on the server using a web browser and select as many as you can at a time and delete them that way. That action will be reflected on the iPad. In IMAP - whatever you do on one device syncs across all devices. If you have POP email - start deleting one at a time.

  • How can I read a LUKS flash drive?

    Hi All,
    http://sourceforge.net/projects/freeotfe.mirror/
    W7 64 bit does not allow you to run unsigned drivers, except in "Test Mode".  This is a problem for Free OTFE as the drivers are (who knows why) unsigned.
    And, the users don't like "Test Mode" showing on the bottom right of their screen.  Turn off the "test mode" and Free OTFE stops working.  And, there are actually some good security reasons to use signed drivers.
    Has anyone come up with a work around?
    A way of reading LUKS encrypted flash drives that has signed drivers?  A sub for Free OTFE?
    A way to allow just these unsigned drivers to operate?
    Only need to read, not write.  If I can only read, all the better!  (Viruses won't jump from my customer's computers.)
    Many thanks,

    Hi Arnav,
       I have been using this method.  This is what I complained about in the original post.  It pops up "Test Mode" in the bottom right of the screen, which freaks out the user.  So, if you want to read a LUKS stick, I have to do the
    above, reboot, read the stick, undo the above, and reboot.  Even though I have copy and paste instructions, including a reboot, it is still a pain in the neck.
    Do you know of a way to tell Windows to bugger off on a particular driver?
    Manya thanks, -T

    I'd still prefer to keep separate user accounts. I never had any issues like this before. The only time I started having a problem was when I was just trying to force empty the trash a few months ago. I came on here looking for a solution and someone posted a way to empty the trash using the terminal. Before then, I hadn't used the terminal for anything--it was just another app in my utilities folder.  (None of this has anything to do with having separate user accounts. Plenty of people with kids make second and third user accounts on their laptops so that multiple people can use one laptop, having more than one user on a laptop is not very difficult.) But thank you, I'll try that out and see if it works!

  • My WiFi name and password has changed. Did someone hack my WiFi? My computer can connect but not my iPhone 5s, and the connection for my computer is full, please help.

    Hello, this is my first post.
    Well lately I've been experiencing some connection issues with my iPhone 5s. I was on my iPhone just watching Youtube when my iPhone 5s disconnected, I tried to connect again by going to settings> Wi-FI> and then select my network as usual, but the weird thing is that my Wi-Fi network has changed it's name to Wireless, it used to be Wireless710. Also the password has been changed.
    My computer can easily connect due to the fact that it is hardwired to the Wireless Cable Modem Gateway.
    Extra Info:
    Carrier is Sprint.
    I am using Windows 7 Ultimate.
    My Wireless Cable Modem Gateway is Netgear.
    And now I am confused because when I open the small tab with the computer and a plug on the bottom right corner next to the speaker icon it says I'm not connected :/?! Here is a picture of it:
    Note that I can not connect to it but am connected on my computer. It just disappeared on my phone and computer, I even unplugged my router waited for 20 seconds and connected it back in. Did it wok? for my computer yes again because it is hardwired, but my phone? No. Wireless 710 still won't show up. Is this a possible hack? Please help me as much as you all can, thank you very much.

    Log in to the router's console with a web browser from your computer. What kind of encryption did you have on the router? If it was WEP that's about as secure as no encryption. It should be WPA or WPA2. There has been an exploit reported in Netgear and Linksys routers that allows someone connected to the router if Remote Access to the console is enabled to take it over and install spyware on it.
    Is it your router, or the cable providers? If it is yours it has been hacked. If it belongs to the cable provider they may have changed it to make it more secure. Call them.
    And if it has been hacked and is yours the best thing to do is to throw it away and get a new, more secure router. Or you can try reflashing the firmware by going to Netgear's site and downloading a clean copy.

  • I need to hook up a WD Elements portable hard drive and Firefox won't let me...any thoughts

    I went to the WE Elements support page for my 250GB WD Elements portable HD and in one of the side bars it mentions on updates there are incompatibility problems with Firefox and Internet Explorer and suggests that I need to downgrade to a lower version of Firefox. Is there anyway of avoiding doing this and getting my back up drive to work?

    A portable HD is merely a storage device i.e. to transfer data from your internal HD to the portable one. Firefox is not involved in that operation since it's only a browser.
    The installation guide is also in PDF format, so you can configure Adobe Reader to open the file outside the browser, so that's not a problem either.
    Where did you see this info about FF being incompatible? On here somewhere? http://www.wdc.com/en/products/products.aspx?id=480

  • How can I deauthorize a computer I returned AND iTunes won't let me deauthorize all of my computers for another 10 months?

        The title says it all.  I returned a macbook that was authorized and got a macbook air instead.  iTunes will not let me deauthorize all of my computers for another 10 months.  So what am I supposed to do?

    Only Support can help you, though I have no idea whether they will.
    Go to https://expresslane.apple.com ; click 'See all products and services' at the bottom of the page. In the next page select 'iTunes', and then 'iTunes Store', then 'Account', then 'iTunes authorisation or de-authorisation'.

  • Drive Mounts But Won't Open (10.3.9) - Please help.

    Hi,
    I have been using 10.3.9 on my dual 1 GHz Quicksilver, very stablely for the past year.
    Today, I clicked on one of my 2 internal drives (not the one with the System folder) icon on the desktop, and first a small window opens, then a couple seconds later, this window expands into a large window, and then disappears. The windows are empty (none of my precious files are visible)! This same problem happens to my external FW400 Lacie drive as well. Only the internal drive with the System folder is functioning normally.
    Here's a twist. I am able to view the contents of both problematic drives using the Finder directory. I am also able to open & copy the files, so I know the hard drives are physically sound and mechanically functioning.
    I should add that I have done nothing differently today when encountering the problem. I've tried shutting down and restarting to no avail.
    Is there something in OS 10.3.9 to remedy this problem (eg drive prefs) etc? I didn't think I need to repair the drives as they work fine through the Finder.
    Thanks for your helpful advice!

    Dear Cine Alter,
    If the two drives are appearing on your desktop that would suggest physical connections are OK. If you have not already done so, start up from you OSX CD and rebuild your directory. Then rebuild Permissions, Restart and see how you go. This process should clean up any directory corruptions which may be responsible for the problem. You should run both of these programs monthly to ensure corruptions do not creep into your system.
    If the problem persists restart from OSX CD and try un-mounting and re-mounting each disk with Disk First Aid. Restart and see how you go.
    Good Luck,
    Tony

  • I purchased a album with a digital booklet. I can't open it on my computer and it won't let me download it to my iPhone. Can someone help?

    One frustrated apple customer.

    Thanks for your suggestion - I have tried that like 50 times (I was feeling the desperation and thought if I reset enough times it would do it), and I have also tried turning off and on the cloud, adding .pages to the filenames, downloading (didn't work) emailing to myself (did work, wouldn't open). When I looked at the package contents of the file, it did not have a file for content in it - or not one I can find. I'm afraid that it's lost the content within the file (though I don't now how it could!).
    I've not had any joy with anything else I have read online. I think it's a more knotty problem than a simple off/on again job!

  • Officejet 150 only prints/reads pictures from Flash Drive??!!

    Everytime I try to print something off my flash drive, the printer will only search for pictures.  It doesn't recognize that there are PDF or Word documents on there.  Is there something wrong or can it only read/print pictures from the flash drive.  Same thing happpens when I try it with a SD card.
    Help??!!

    Hi Emmee102,
    The Officejet 150 can only read photo files from the USB flash drive and SD card.
    A couple of workarounds can enable you to print from your ipad to the OJ 150:
    1) convert your pdf/word files into jpeg/jpg format and save to the flash drive/SD card
    2) use print screen from your PC , this is good if you only have a few pages in your document.
    Hope this helps.

  • I have an external hard drive, from Iomega. However, I cannot copy or save any file to it. On my PC it says that is possible to read and write in it, but in my Mac, it says I can only read. can somebody help me?

    I have an external hard drive, from Iomega. that I can open and see my files. However, I cannot copy or save any file to it. On my PC I have it says that is possible to read and write in it, but in my Mac, it says I can only read. can somebody help me?
    Also, Im a photographer, so I like to name a lot of files at the same time (used to do in on PC and it was very usefull.) cannot find out how to do it on my Mac. Really appretiate if some one can give me a solution! Thanx

    Your drive is formatted with the NTFS file system.  OS X can read but not write to the NTFS file system.  There are third party drivers available that claim to add the ability to OS X to write to an NTFS partition.  I have not tried them and don't know if they work.
    The only file system that OS X and Windows can both write to natively is the FAT32 file system.

  • Leopard to Snow Leopard can i use a large flash drive to backup first?

    I've been using Leopard for 4 years with no problems. 
    Since Google decided to stop support for Leopard, and I use Chrome a lot I decided to upgrade.  I won't be upgrading to Mountain Lion right right away. I ordered my Snow Leopard disks from Apple.
    I understand that I need to backup.  I want to backup with Time Machine before I upgrade the OS, but I don't have $75+ right now to purchase an external hard drive for this purpose only. 
    Can I use a large Flash Drive to run Time Machine?  Like a 32 GB?   I know that flash drives have a limited number of writes on them and can go bad, so I am thinking I could just use it this one time to make sure I have a clean backup.  If this is possible, then can I set up Time Machine again later when I have an external drive?
    Also, I have 2 cores on my Mac, but I have no idea how to use the 2nd core. 
    I'm also not sure if I need to purchase a specific external drive because I have a mac. 
    Thanks for the help.

    If you only need to make a full backup prior to upgrading, I would suggest using SuperDuper, which for creating a full, bootable clone is free. (It is not free when you start needing to make incremental backups, but you won't be doing that, at least not right now.) For a bootable clone, you only need a Flash drive (or external drive) as big as the total size of the utilized space on your hard drive right now, not as big as whatever the entire drive size is.
    In the past, I would have recommended Carbon Copy Cloner for this, but it's no longer free or donation-ware and you don't have the budget for both that and some kind of external or Flash drive.
    http://www.shirt-pocket.com/SuperDuper/SuperDuperDescription.html
    You might also want to look around newegg.com for inexpensive USB external drives, or even large enough Flash drives. You'll probably find a much less expensive external hard drive than a Flash drive for this purpose.
    You do not need to use Time Machine, but even if you did you could just make one full backup to a Flash or external drive and then unmount and disconnect it. An external for TM only needs to be so large because it's constantly taking snapshots of your drive and those add up. But you won't be using it that way.
    Anyway, I think you're much better off with a bootable clone, should you need to restore that.
    Don't worry about having 2 cores; that's nothing to do with backing up.

  • I erased my HD. Now I can't instal mountain lion from my bootable flash drive, and keep getting "installation error. Try again."

    I bought  mountain lion, made a bootable flash drive.
    I booted from it and it went to upgrading right away!
    So I stopped it and went to my former recovery partition I erased my HD because I wanted a clean start.
    Now I can't instal mountain lion from the bootable flash drive, and keep getting "installation error. Try again."
    and there is no 4 choices window.
    I don't know what to do.

    How did you create the USB install thumb drive? If it was with Disk Utility I have run into this problem and have since used THIS program to make the USB install drive.
    As to your problem you only have one option and that is to Reinstall the Original OS X version that came on your computer or if you still have the Lion Recovery Partition use that to reinstall Lion. Or if you system came with Lion and you have No Lion Recovery HD Partition you can boot the system from over the internet and Reinstall Lion.
    At startup hold down the Command+Option+r keys until you saa a spinning Globe in the center of the screen. Once that loads Repartition the drive as One partition and then reinstall Lion.

  • Can I create MacOS on flash drive to run broken Imac?

    So I've got an Imac that's all brokedy. Won't start up. I tried reinstalling Snow Leopard 10.6.7 on it from a boot disk, but got referred to Disk Utility. Disk Utility told me that the GB 500 drive was so fricked up that Disk Utility can't do a thing with it, I have to take it to a repair shop. But the Apple MacIntosh HD that's INSIDE the GB500 drive checks out OK according to Disk Utility.
    It occurred to me that I could maybe install the Snow Leopard software into a flash drive and run the computer off of it, accessing the data and software on the MacIntosh HD via the flash drive, and at least being able to salvage important files that way. I'll need at least a 16 Gig flahs drive for that, no biggie, but my question is: is this feasible or some mad fantasy I've created out of an absurd desire not to get my wallet hijacked by Apple?

    I think you'll find that your Hard Drive is failing, I hope you have some form of backup.
    Your idea of creating a bootable flash drive could work but it will be useless if your HDD fails which according to your SMART status could happen soon.
    I would make a full backup of your hard drive onto an external hard drive using Time Machine or another preferred backup method.
    Then I would look into replacing the drive by myself or taking it to an Apple Store.
    Good Luck!
