  Hi FAH300,

  If you are not able to format the drive, there may be a hardware problem.

  I suggest formatting the disk using the instructions linked by wb2001.

• External drive not recognized

  Hi all

  I unplugged a USB external drive for a few days of my Netgear RN102. Now, when I've reconnected, the Nas does not recognize the disc. The data is safe, if I connect the drive directly to a PC, I see all the folders and files.

  Is there a way to see the drive on the NAS without erasing it?

  Thank you

  Marcello

  Indicate your logs

  volume is dirty and 'force' flag is not set

  If you hang the external drive to your PC and fix you should be able to then reconnect to the NAS.

  Unable to content on a USB flash drive, not getting not formatted. It is within the warranty period. How the guarantee?

  Only if the drive was still usable and allowing for the write you to read the summary file but not. A read-only error.

  You declare that you cannot access the drive at all, is - this correct? If so, I would get the replaced disk.

• Why my XP does not recognize a Toshiba 500 GB USB external drive... it does not appear in disk management or in computer

  Bought a new Toshiba 500 GB drive external usb.  My XP desktop won't recognize/find this disc.  It does not appear when you view the disk management or work station.  I also have it on my new laptop (Vista) and it has been found immediately.  My research online only tells me to find the external drive in disk management and assign a drive letter to... but I don't think to assign a letter!

  Three things that you have not yet mentioned are

  1. don't change you the registry suggested by the KB Article (see: a computer that is running Windows XP cannot detect a USB flash drive, an iPod from Apple or an external hard drive)?  I suggest do it manually instead of using the FixIt.

  2 represents the drive recognized in the Device Manager (start > run > devmgmt.msc > OK)

  3 is the drive recognized in your BIOS (press the corresponding key on startup).

  Reformat to FAT32 was probably not necessary (and you'll probably want to re - format to NTFS before use).  XP has no problem with large (> 500 GB) external USB drives.

• Why the files are stored on an external drive not appearing in the "other" classification on my iMac HD?

  I'm running OS X version 10.11.4 on an iMac, retina 5 K 27-inch/3.5 GHz Intel Core i5 with 24 GB RAM/1 TB HDD and I have had for about a year, although I migrate some files over my old machine, but most were on an external.  I have almost all my larger files on an external drive 2 TB - for the most part hi res .eps, .jpeg, .png.

  I run CleanMyMac 3 as a utility. When I saw recently that I had more than 600 GB of 'others' I decided I have to spend the day to clean my files and machine - and have therefore been sucked into this rabbit hole.

  After cleaning duplicate files, empty the caches, removing unused applications and clean the external hard drive, I have still 570 GB of "other".  When you click on the bar in their own my Mac, it gives you a list of what is included in each of the classifications of file storage.  I understand, including all Documents to plain text, PDF and even files .docx, ect...

  what I don't understand is why:

  1 .pages (documents created in the clean Apple program) are not classified with documents, rather than as 'other '.

  2. why each of my .eps files that are stored on an external drive also claim space on my Mac?  It would potentially be the preview images displayed in the Finder? And if so, why it store a snapshot of the same size as the actual file?

  AND, most importantly, I can recover some of the disk space consumed by the huge amount of .eps files?

  Thank you

  'CleanMyMac' is a scam and a frequent cause of instability and poor performance. Depending on which version you have, the developer's instructions may not completely uninstall. Please follow these instructions, then do as below.

  Back up all data before proceeding.

  Triple-click anywhere in the line below on this page to select this option:

  /Library/LaunchDaemons/com.macpaw.CleanMyMac3.Agent.plist

  Right-click or Ctrl-click on the highlighted line and select

  Services ▹ reveal in Finder (or just to reveal)

  the contextual menu.*, a file can open with a selected item. If so, move the selected item to the trash. You may be prompted for administrator login password.

  Repeat with this line:

  /Library/PrivilegedHelperTools/com.macpaw.CleanMyMac3.Agent

  Restart the computer and empty the trash.

  You may also delete one or more of these elements in the same way:

  ~/Library/LaunchAgents/com.macpaw.CleanMyMac.helperTool.plist

  ~/Library/LaunchAgents/com.macpaw.CleanMyMac.volumeWatcher.plist

  ~/Library/LaunchAgents/com.macpaw.CleanMyMac3.Scheduler.plist

  Never install "CleanMyMac" or something like that.

  * If you do not see the item context menu copy the selected text in the Clipboard by pressing Control-C key combination. In the Finder, select

  Go ▹ go to the folder...

  from the menu bar and paste it into the box that opens by pressing command + V. You won't see what you pasted a newline being included. Press return.

  B

  For the other category in the display of information storage, see this support article. If the display appears to be inaccurate, try to rebuild the Spotlight index.

  Empty the trash if you don't have it already done. If you use iPhoto, emptying his trash internal everything first:

  ▹ iPhoto empty the trash

  In pictures:

  ▹ Show of the recently deleted ▹ file delete all

  Do the same thing in other applications like Aperture, with an internal feature of the trash. Then, restart the computer. Temporarily, which will free up space.

  According to the documentation from Apple, you need at least 9 GB of free space on the boot volume (as shown in the Infolog) for normal operation, not the mythical 10%, 15% or any percentage. You also need enough space to allow the growth of the data over. There is little or no advantage in terms of performance to get more free space than the minimum Apple recommends. Storage space you'll never use is wasted space.

  See this support article for some easy ways to free up storage space. A common waste of space is old backups iTunes to mobile devices. As shown in this support article, select the devices tab in the iTunes preferences window, select the backup that you want to remove and click on delete the backups. Keep at least a backup of each device you use yet.

  You can use a tool such OmniDiskSweeper (ODS) to explore the volume and discover what is take up space. You can also delete files with it, but not unless you don't know you know what you remove and that all data is stored safely. This means that you have several backups, not one. Note that CESO works with OS X 10.8 or later.

  Deletion of files inside a photo library or iTunes will damage the library. Such a library should be changed within the application that created it. It is the same for e-mail files.

  Go further than if the problem is not resolved by the steps above.

  ODS cannot see the whole file system when you run simply by double-clicking; He sees only the files that you have permission to read. To see everything, you must run it as root.

  Back up all the data now.

  Install the application in the Applications folder as usual. Quit it runs.

  Triple-click any where in the text line below on this page to select, then copy the selected text in the Clipboard by pressing Control-C key combination.

  security execute-with-privileges /A*/OmniDiskSweeper.app/*/M*/* 2>&-

  Launch the Terminal application integrated in one of the following ways:

  ☞ Enter the first letters of his name in a Spotlight search. Select from the results (it should be at the top).

  ☞ In the Finder, select go utilities ▹ of menu bar or press the combination of keys shift-command-U. The application is in the folder that opens.

  ☞ Open LaunchPad and start typing the name.

  Paste in the Terminal window by pressing command + V. You will be asked for your login password.

  The application window opens behind other open windows. When you scan a volume, the window will finally show all files in all folders, sorted by size. It may take a few minutes for the app to finish scanning.

  I do not recommend that you make a habit of doing. Do not delete anything as root. If something should be deleted, make sure you know what it is and how it got there, and then remove by safer alternatives. If in doubt, leave it alone or ask for advice.

  When you are finished with the app, he quit and also to leave Terminal.

• A satellite - DVD Drive not seen by Windows Explorer

  The DVD on D deive is not seen by windows Explorer. Used to work, it has now disappeared. The dvd hardwars starts at the start, then stop.

  Any ideas anyone?

  Hello

  You see the DVD drive in Device Manager and you then yellow exclamation points?
  Maybe you should just remove the drive from Device Manager and reboot the laptop. Select the drive in the Device Manager, right-click on it and choose uninstall. Then, restart the laptop.

  If it doesn't work try the workaround posted by Akuma to remove upper and lower filters.

• P7 - 1436 s: Second hard drive not seen by Win10.

  I physically installed a Seagate Barracuda 2 TB HDD in my office as additional data storage.  He is not seen by the operating system.  I followed the instructions and the video on this site.  I have installed and run the Seagate drive Wizzard but he does not see the new hard drive either.  The new drive is connected to the SATA1.  Power is the second connector on the cable that feeds the original hard drive (drive C).  I noticed that the hard aiinstalle plant is a Seagate Barracuda 1 TB so I guess tha the new drive must be compatible.  The computer works normally.

  Do I have to activate the new hard drive in the BIOS, and if so how do I do that?   (I make sure all the cables are in place.)

  Notice of another forum was to click on the 'Simple Volume' and then format.  I did it and here he was there.  I was able to access the drive again now.  Thanks for all the help.

• DVD drive not seen by Windows 8

  I have a Dell Inspiron with Windows 7 537 originally. The installed and functional DVD drive is a TSST DVD +-RW TS-H653G ATA drive.

  I have recently installed WIndows 8 in dual boot. When I boot with Windows 8, the DVD drive is not seen. When I go to the Device Manager and I look at the properties of the DVD player, I have the following message appears in the device status area (here I give a translation of the message in french)

  This device is not actually connected to the computer (Code = 45).

  To correct this problem, reconnect the device to the computer.

  The fact is that the DVD still works fine when starting with Windows 7.

  Do I need a new driver or a new device or what else?

  Hi Marcel Painchaud,.

  I appreciate the time and effort you took to resolve the problem. Please do the following:

  1. run the command as administrator prompt. Type cmd in Windows 8 modern user interface and press HUMINT + shift + enter

  2 type following and say enter

  Reg.exe add "HKLM\System\CurrentControlSet\Services\atapi\Controller0" / f/v EnumDevice1 /t REG_DWORD /d 0x00000001

  3. reboot the system

  Once the system is restarted check if the DVD player works fine.

• Why is my 64 GB USB Flash Drive "not a backup location valid?

  I tried to turn it to a previous question, but reading of the Code of conduct for this forum, I discovered that it was inappropriate to do that.  My apologies for this.

  I am running Windows 7 Home Premium 64 - bit SP1, installed using Toshiba recovery disks (I have a new Toshiba laptop, when I got the system I opted to not have a recovery partition).  I just cleaned all the bloatware off Windows, ran Windows Update until there was no more updates for (achieved in this way SP1), and now I have a fresh and clean windows installation, which has never even been to a single Web site.  Now, I am trying to create a system image on a 64 GB flash drive (I won't even finish by using half of it, as my SSD has only about 19 GB used, and which includes the hibernation file (I disabled the pagefile, because paging files are unkind to SSDs))

  Before, I asked if it was possible to manually create a System Image of Windows 7 on a USB Flash drive (big), and I got two answers 'Yes' to two stars of the community. (See my question here)  It is also stated that it is possible on windows.microsoft.com, here.  Note that when windows.microsoft.com stipulates "the system image must be saved on a hard drive, reference is made to automatic creating system images.  If you keep reading, you'll see that the page says that if you want to manually create a a system image, this image of the system may be recorded on optical discs, a USB Flash drive or a hard drive.  If it is possible, then why will I have the following problem?

  64 GB USB Flash Drive inserted--> closed Autoplay dialogue--> Opened "My Computer"--> Right-clicked drive E (my flash drive) and the selected format--> Unchecked 'Quick Format'--> size of the NTFS system chosen and 4096 bytes of cluster--> Clicked 'Format' and acknowledged that all the data will be deleted--> waited a while for the form to fill out, then clicked OK--> closed 'My Computer'--> ejected my flash player by clicking on 'remove hardware safely'--> physically unplugged flash drive--> Grabbed a diet coke with ice--> inserted 64 GB USB Flash drive--> AutoPlay dialog closed--> opens the start--> Clicked "All programs" Menu--> clicked maintenance--> click Backup and Restore Center--> clicked on create System Image--> (scans of program for storage devices)--> my flash drive appears under "on a hard drive" and the words 'the drive is not a valid backup location' appear under my FlashDrive being listed.  For reference, "on one or more DVDs" appears just below the text saying "the drive is not a valid backup location."

  My understanding is that what I just tried to do is create an image of the system on an NTFS partition formatted (with a 4 KB cluster size) 64 GB USB Flash Drive.  But it is not letting me!  I understand that I can't plan the creation of automatic system for USB Flash drives, but according to windows.microsoft.com image and two stars of the community, it is indeed possible to "manually" create a system image on a large USB Flash drive, which I think is what I just tried to do.  If there is another way to create a system image, even more 'manually' than what I do (I'm certainly not afraid of the command line, if I need to use it I'm more than happy to do so), please let me know.

  I have a low-quaility SATA 3.0 Gbit/s notebook HDD in an enclosure USB powered bus at low prices, and I was able to create a system on that image.  However, I expect this device to fail shortly.  I also managed to create a system image on a DVD-r virgins.  I did, however, just spend $85 on a 64 GB USB Flash Drive specifically to store an image of the system, which I expect to use to back up Windows 7 with World of Warcraft installed (total size of drive C will be approximately 50 GB; I have not yet downloaded WoW; "I want to overcome this first).

  Any ideas would be appreciated.  Thank you!

  1st edit: adding links so people would not need to copy and paste to their address bar and said the last sentence of the last paragraph.

  I suggest avoid you the Windows backup program and you get a good commercial backup program. This forum is frought with for a windows problem reports. I know that I was very impressed when I tried it. Two me are familiar with and like Norton Ghost (which I use for 7 years without the 1st problem) and Memeo, which has 30 day free trial and you can buy it for $29.99 - you can download it from http://memeo.com. You can get Ghost for almost nothing (like me), if you look at the sales.

  CNET has a lot of reviews of backup program to

  http://download.CNET.com/Windows/backup-software/?tag=contentBody;sideBar.

  Some of them are free (the last time I checked there are 315), some have free trials (more), and some are buying only (more than 200).

  Good luck.
