binary data loss

I am running a VI which each loop saves a 1 d array to a binary file. I leave the loop run thousands of times, but after I sent the binary data in .xls format, I noticed that it was down the last few hundred loops (because I know that data should have looked like). Basically I was running a wave form and it seemed as if when I let the waveform 4 times, cycle 3 present you would Excel in. Is there a reason for this?

The fixed! I used the skeleton to read a binary file for the example for my vi section and the skeleton was equal to 8 bytes of data size. Apparently, mine is 4 bytes? and so 8 was originally think that it there was only half because the amount of data that it has been. I changed and all the data is there! Thank you!

  • What are the causes of data loss during an update?

    Just what are really the causes of data loss or corruption when you update. Most sites will tell you to back up what I'm doing, but none of them actually appoint a cause to save.

    -Thanks in advance

    Minor updates in an OSX * may * break the file system.  Fully upgrades to other OSX replaces almost all file systems.

    Some backup of people even before you install some software packages, because they know how this package changes directories OSX.

    Backups are never a waste of time.

  • Need help to avoid data loss on a corrupt and/or failure to hard drive

    I don't know what happened. One minute I'm surfing the web and listening to music on iTunes. Then out of nowhere he had a sudden failure. Changed not long at all, but now when I try to turn on my computer, it starts normally but then shortly after that the chime and the apple logo appear, if a progress indicator yet that I've never seen before today. Until the progress bar is still the size of my little finger nail, the computer turns off just. I started in recovery mode and run disk check and repair utility. Make sure the disc is not far off when he said something like - disc cannot be checked completely. Disk needs to be repaired. So when I click on the repair disk, it works only for maybe a minute before it comes up saying - utility disk can't repair the disk. Upwards from your many possible files, reformat the drive and restore your backed up files. So obviously it's not good. What are my options and can I do to avoid losing data that is not already saved? I have a lot of things that have not been backed up and lose some of them would be pretty damning. That's my main goal; data loss as little as possible. My computer is an iMac 2012 end Mavericks 10.9.5 running.

    Thank you.

    You do not have a current backup? If this is not the case, your only real option may be to pay a data recovery company and see if they can help you. Which can be very expensive.

  • binary data from GPS VI-example RF recording / reading with NI USRP

    Hello

    In the demo video (http://www.ni.com/white-paper/13881/en) a ublox was used to record the GPS signal while driving. How is it possible to record with you - Center in a binary data format which is usable within LabView for the reading of the GPS signal? Ublox uses the *.ubx data format, is there a converter?

    Hello YYYs,

    The file was generated not by uBlox but by recording and playback VI.  An active GPS antenna, fueled by some amplifiers and mini-circuits was related to the USRP and the program created LabVIEW file (USRP being used as a receiver)

    Later the USRP is reading the file (generation) and the Ublox GPS receiver is to be fooled into thinking that its location is currently somewhere else.

  • Cluster of savings in the form of binary data

    I have a compound cluster of ~ 50 items of different types that I need to save it as binary data. Obvoiusly I could do with the method of "brute force" of 50 different entries in the file, but that seems silly.

    Is there an easier way to empty just the disk in the form of binary data?  By registering as a cluster seems to add extra characters.

    In a world of LV, I just recorded in as a variant, but it must be saved as binary raw in order to be read by another program as a C structure.

    There is the beautiful Boolean entry in the binary write for "add/array of strings of size."  Unfortunately, this boolean applies only to the type of upper-level data that is being written.  So whatever it is inside the cluster will always these lengths prefixed.  Therefore, you have to separate your data and write each piece individually.

  • Producer/consumer vs Master/Slave of data loss

    Hello users of Labview,.

    I did experiment with vs p / M/S lately in the context of data aquistion. Many messages did appear (correct me if I'm wrong) that p/c is the correct architecture to if the data retention is desired, so that's what I tried to implement.

    In the loop of producer, I've included 3 Assistant DAQ VIs (2AO, 1 HAVE), which generates data actively and which is being queued. I have 3 other loops of consumers, two of which are consumer 1) written loops of 2) outputs TDMS data of a chart 3) no producer: structure of the event, monitors changes to the user interface.

    When I run data acquisition, the generated file are always half either acquire the half of the sample that I've specified regardless of the sampling rate. I also have a strange displayed graph (see image).

    However,.

    If I replace with a master/slave architecture, this seems to solve the problem.

    So question is: anyone met with this kind of problems? Are there disadvantages to stick with M/S instead of p/c in terms of data loss?

    Thank you

    I think I'm well done

    You are not.  Once an article is removed, he went.  Since you have three loops made of the same queue, each loop will get ~1/3 of the data.  If all the loops are to treat everything, then you want another line for each loop and meet the producer, write to each queue.  You can also use a user event.

  • Handling of binary data (TCP/IP)

    Hello

    I was wondering if someone could point me in the right direction of processing continuous data TCP/IP and more meaningful information. Data contains 'an array of 10 tanks. For the sake of the argument, I saved some data in a text file. I tried to use the typecasting and unflatten to the chain function to convert the data to ascii in real time, but my lack of knowledge with the conversion of binary data makes it very difficult.

    Luckily, I got to convert binary data stored in a table of numbers of single precision that displaying the correct values. However, I am still confused in doing so in real time. I have attached all of the data and the example vi.

    Thank you

    Sam

    After hours of searching on forms.ni.com and I was able to convert table 10 floating point values readable in LV values as drjdpowell has pointed out that using modern "Unflatten chain" is much easier to accomplish this task. Because I had to deal with the old version of LV (7.1), I had to use cataloged with loop I32 array type, For, Swap, Swap bytes words and catalogued with array type SGL. Please refer to join .vi for more details.

    Hello Kuldeep,

    Thanks for posting your question on the Microsoft community.

    We need more information about the issue so that we can help you better.

    What is the exact error message or code when you say, 'mislead the GPT?

    Thank you for details on the issue.

    GUID Partition table (TPG) is a new style of partitioning that is part of the Unified Extensible Firmware Interface (UEFI) specification. This is used for Windows 8 facilities factory for more flexibility of partition and

    more advanced features of Windows 8. With an installation of Windows 7, the GPT partition must be removed and UEFI BIOS must be configured in a configuration to boot Legacy.

    Important notes:
    Converting a hard disk partition or volume from NTFS to FAT32 requires that you reformat the partition, which deletes all the data on this subject. Be sure to back up data that you want to keep before you begin.

    BIOS change / semiconductor (CMOS) to complementary metal oxide settings can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the configuration of the BIOS/CMOS settings can be solved. Changes to settings are at your own risk.

  • Transfer of files between drives: data loss or corruption?

    1. Is there data loss or corruption during the transfer of files between disks in Windows 7?
    2. What about very large files, gigabytes in size?
    3. Is it possible to check if there is data loss or corruption?

    Creation and verification of a checksum is a file operation.  It doesn't matter where the files are stored.

    It doesn't matter if the source is a CD, a USB flash drive or a hard drive.  As much as the destination is concerned, if you write a large file on a CD, the possibility of error is greater if copy to a USB flash drive or an external hard drive.  Which is why you often see tips to burn at the slowest speed available when writing large critical files as an ISO installation file.

    The only difference between 'copy' and 'move' is this movement copies the file and automatically deletes the original.

    You want to make sure that the file copied correctly before the original has disappeared.  The way to ensure that is to perform a copy operation, check the integrity of the copied file and delete the original.

  • How to convert binary data NVARCHAR2?

    Hi all

    I have binary data in the database (RAW oracle data type). I know that these data contain string encoded in UTF8. Our database runs in WE8ISO8859P15 encoding, UTF8 national character set. Then I would just convert the binary data NVARCHAR2. How can I do?

    I found the UTL_RAW function. CAST_TO_NVARCHAR2. However, this function takes only binary data as a parameter, so I highly doubt that it will work as I hope without specification of source character set...

    Someone has an idea?
