Problem with external hard drive (an unexpected error - 50)

I've had this problem for a few months now. Sometimes, I can't delete a file from my external hard drive, or export a file to it. The process is impossible, and I get a message "Cannot perform the action due to an unexpected error - 50". Ejecting the disc gives the message "eject impossible because another program can use it." Ejection force becomes the only option. After re-login, the problem goes away, like nothing ever happened.

The question is not constant, but quite common to become a nuisance, the one I want stopped.

That's what I think it is (a bad connection with the cable, defective contact), or is this a virus? I need to know.

The hard drive is 1 TB Toshiba Canvio Basics and is formatted as Mac OS extended (Journalized).

not a virus, and not only because there is no virus mac at this time.

negative errors on the discs can be a signal indicating that the file is corrupted or worse still, the drive is failing. While it can also be a problem with the cable or the connector that it commonly goes back on the disc itself.

Currently, it is recommended that you backup your data if a backup fails, you may need to save what you can manually and sometimes that means go to this folder by folder or file by file

Use Time Machine to back up or restore your Mac - Apple Support

All HARD drives (and SSD') eventually fail and while this isn't a your statement you should check the drive with disk utility (Macintosh HD/Applications/Utilities/Disk Utility) after you got what you possibly can off and consider replacing the disk with a new one.

  • Problem with external hard drive 500 Gb Stor.e Steel

    Hello

    I ve bought a Store.e steel 500 GB external hard drive and I can't get large files (such as 4 GB) it wit. There is a message that says that the file is bigger that the system supports whenever I try to get a file of 4 GB, but I have 300 GB of free.
    What evil?
    Thank you

    I agree with user Stephen.
    The file format of HARD drive seems to be FAT32, you must format the HARD disk to NTFS to be able to manage files over 4 GB.

  • Problems with external hard drive files, Aperture & keep open.

    When I opened (ie the "expand") the folder to an external drive such as a USB key, I want it remains open (expanded). But as soon as I open another folder on the C: drive (ie the root directory), the external drive folder closes its doors (IE 'collapse' s). It's annoying, I have to re - open every time I want to copy a file to it. How can I make such a record remains open until I chose to close it?

    Also, is it possible to make her open folder (ie the "expand") automatically when I plug in an external drive, including a USB Reader/key/paste?

  • Problem with new HARD drive and Qosmio Player installation

    Hi all
    I hope someone can help, I had my Qosmio for 2 1/2 years now and recently had a problem with the hard drive. I decided to replace the hard drive, because it was the fastest solution. The problem I have now is that I can't receive TV on media center. I tried to install qosmio player at the disk to see if it made any difference, but when I run the provided recovery disc software tells me that there is not enough disk space! The laptop came with a 60G hard drive and the new HARD drive manufactured by the same manufacturer is a 150 GB, can someone help me out with this would be appreciated.

    Thank you
    ED.

    Have you tried to install Qosmioplayer initially, then on operating system? If I remember well, on this first portable Qosmio, it was very important to install Qosmioplayer initially.

  • E3000 displays "USB is not supported" error with external hard drive

    I have the E3000 router and recently bought a USB WD (Western Digital) 2 TB external hard drive.  I plug the HDD on the router, open the home page of the router (http://192.168.1.1/) then click on storage > disk and I get an error of "the USB is connected is not supported"-suggestions on how to solve this problem?

    Thanks for any help!

    I had the same problem with my WD hard drive today after setting up my E3000. Remove the protection 'security' or the password on the disk as well as level of what the duration of sleep obtained took care of this problem. My WD is now working with my E3000 seemlesly.

  • Start with external hard drive problem

    I recently bought a Western Digital 1 TB external hard drive. When it is connected through the USB port my Pavilion a815n Windows XP hangs on the blue HP screen at startup. Western Digital technical support Advisor info sent to me I need to change a setting in BIOS but I can't find the trunk of USB device option setting in the BIOS of HP.  Can you tell me how to access this setting, or what else to do to solve the problem?  Thank you!  Jake

    Problem:
    After connecting a device USB to the PC, the computer does not start in Windows.

    Cause:
    The motherboard has a boot from the USB device, or a similar option, which is enabled in the system BIOS.

    Solution:
    In the system BIOS, disable the option to boot from the USB device and the USB Legacy Support option. This will allow the PC complete the process on the internal hard disk and allow you to enter Windows. If this does not work for any reason, you should boot your PC before connecting the USB key. Once the computer is fully booted Windows, plug the USB and wait for the operating system to detect the drive.

    Update the BIOS seems to have solve the problem. It was normally restarted with the attached hard drive.  Thank you!!  Jake

  • Qosmio G30 (PQG31) - problem with cloned hard drives

    Hi all!

    * Qosmio G30-154 * (* PQG31 *).

    Demo of the Qosmio has 2 hard drives with XP MCE (32 bit) installed on the primary.
    The RAID parameters are JBOD.
    BIOS is "newer" 3.90

    I would try to upgrade the drives (without installing any OS) and... have a problem!
    BSOD "Stop 0x0000007B" after 'clone with resizing' for the main HARD disk.

    I read on [drivers Toshiba RAID | http://forums.computers.toshiba-europe.com/forums/thread.jspa?threadID=48489] also [how to integrate the AHCI driver when installing Windows XP | http://aps2.toshiba-tro.de/kb0/HTD9401AN0000R01.htm] and (or)

    F6 (for all usb drivers) is not available to boot OS, sorry.

    "cloned" drive is in line with the correct name of made in the BIOS. "Cloned" secondary drive works (with old primary school). How to get access to the new primary OS and loading cloned? Please, any ideas?

    Thank you.

    Hello

    I think that the system cannot boot to the new HARD disk as the partition where the system is installed, was not marked as bootable system partition.

    I recommend to insert the previous HARD drive and to start the laptop.
    HARD drive new, cloned could be connected as an external HARD drive to a USB port.

    Then you should go to disk management (right click my computer - manage-> management-> disk management computer)
    Here you can see the HARD internal disk and the 2nd HARD drive connected to the USB port
    Right-click on the partition (2nd HARD drive) where the Win XP has been installed and choose the partition as the system partition and mark it as active.

    Then you could change the HARD drive again and could power the device in place. Usually, the system should boot to the top of the new marked system partition.

  • Tries to access an external hard drive get the error "system error 1130 has occurred."

    I have an old box with Windows XP Professional SP3 installed that I use as a file server. I installed a 2 TB external hard drive and set a couple of actions on it. Everything worked fine until 2 weeks ago when I lorsque je pouvais pouvais join is no longer to the actions of one other machines of the network: whenever I tried, I got:

    1130 system error has occurred.

    Not enough server storage is available to process this command.

    I installed the additional memory (now 2 GB), nothing helps.

    The really strange thing is: I can set and use actions on the C drive (a small disc 40 GB, only containing the operating system). but actions on the external drive D (the big disk) do not work.

    Someone has an idea?

  • Problem with external HARD disk - cannot mount the mac partition and can't unmount the partition windows

    Hi all

    Need your help. I have problems with my external hard drive. I worked on it yesterday when the cable is a little detached and disassembled my intestinal HARD drive.

    Here are the specs:

    1 Macbook Air 11.5 "running on El Capitan (10.11.1)

    2 Buffalo Ministation external (1 TB) HARD disk divided into two: a Mac partition (for time machine) and the other a windows on FAT32 partition.

    Before the accident yesterday, it was working OK.

    Now, when I connect the HARD drive, it turns on but the Mac partition cannot be mounted (it does not appear on the Finder. I opened disk utility... just load forever and does not work) and the Windows partition is visible... but I can't take it apart without turning my computer.

    I can assemble and disassemble a USB stick very well.

    Any help would be appreciated.

    Thank you!

    Maybe you can explain a little better.

    I would like to make some general comments before having your replay.

    It is not wise to use TM on a disk with apple unformatted or partitions, it is preferable to have a dedicated TM drive also.

    For TM, the rule is that the drive is about 3 times the size of the boot disk.

    Normally you 'survive' a good step disassemble the drive external, but in this case with a another partition formatted on this subject, I'm not sure if that do not corrupt the disk, especially since the Windows partition is bootable. I have suspct the partition GUID on the TM partition table is corrupt.

    I propose to start the disk completely: in DiskUtility select the 'higher' level (name of manufacturer) and the Partition, one OS X Extended (journaled) partition table Partition GUID. And use it only for TM, is not too big for this.

    Have another drive formatted NTFS for Windows.

  • Help with external hard drive

    I use an external hard drive Seagate for my photos and I have been use for more than a year, today when I used it, my windows 7 laptop not recognize it so I couldn't see the files but I knew that it worked as I could hear, I then plugged in a computer laptop windows 8 and it's the same thing. I used another cable, still nothing has changed. Could someone tell me how to solve this problem that I don't have a return to the top of the images.

    Hello

    This is a problem because it is not recognized by Windows 7 or Windows 8 machines.

    I would try it on a 3rd machine, such as pointing to something to go wrong with this Seagate HD.

    And hearing that HD is not a good sign either.

  • Problem with connector hard drive to spring on T43 motherboard

    My T43 (type 1875) cannot operator unless I am pressing on toward the down on the palm rest above the spring certainly drive connector.  This connector seems to be designed to move upwards & downwards on two positions.  44 pin hard drive seem to connect indirectly to the motherboard via 44 springs in this assembly.  This Assembly should be compressed manually for the system to communicate with the hard drive.

    I do not understand the physical design of this connection?  I certainly do not understand the purpose of this complicated mechanism.  It is part of the protection of the hard drive?

    To correct the problem, I see two possible solutions;  either compress the springs, then bend the stems of alignment to maintain the State of compression, which makes electrical connections or replace the motherboard.

    If someone put me on how I could fix this?

    Note of the moderator; email address removed before finding too much spam

    This is common with the T4x problems and those who have not been carefully reassembled since the Council can become cracked over time especially when door one-handed from a corner as a person would natrually.

    Even models 15 inches and their solid upper bezel can experiencine this issue, but the models 14 inches and the palm rest of split and are the most sensitive.

    The system works when you press the right ALT just below and to the right of the trackpad?

    If you took the palm rest off the power, then press the plug of the battery, it restores the operating system?

    If so, you may be lucky that the Council itself cannot be cracked but it could be the connectors of taking battery BIOS on the Board and in this regard a $3 repair. Cut the connector and replace with a new one or cut and reweld to ensure that the circuit is solid.

    If it is cracked, you can hold with some high quality neoprene since used neoprene "shrink as styrofoam when exposed to heat and pressure. Shim planks will run, but the added stress of ttignehtning it back together can create other pauses as you are bowing the bridge so that the stress has to go somewhere.

    In addition, the system will work better if it remains stationery for a portable shim will pass when the goods are shipped under nomral conditons.

    Finally, the entire system will be brick and you can save or part the rest of it.
