    How SAFELY can you TRANSFER the DATA from a REDMAG?

    If I copy the Data to a Laptop HardDrive, will the Data be "secure" and accurate, or do I need
    to actually watch all the footage to verify that the Data is correct (before I record over the RedMag)?
    I use TeraCopy to copy Data on my Windows systems.

    Is there a VERIFY RedMag Files software tool out there that can check all the transferred Data
    so that I can move on and record over the RedMags?

    Is there a stand alone device out there (no laptop or common computer inline) that would allow me
    to simple slide a RedMag into it, then push a button and have the Data from the
    RedMag copied to an attached HardDrive?

    Is there a device out there that does use a laptop or common computer that would allow me
    to simple slide a RedMag into it, then push a button and have the Data from the
    RedMag copied to an attached HardDrive? And if not a device, then software?

    Can I pay someone to make such a device if it does not exist???

    :)

    Yes, its called Red Data Manager... and it costs 80 dollars.. It does reliable copies and check sums, great tool

    Thanks Brian.

    So if you use this program, then does it mean you do not have to actually watch all the files
    and can delete what's on the RedMag without worries?

    You can run a checksum that verifies the transfer. You know the footage transferred bit for bit successfully after a verified checksum, so now it's just a matter of the storage media you transferred to is safe. RAID and redundancy is where it's at from then on out.

    If you're dealing with multiple formats, Shotput Pro is great as it supports most every recent codec out there including Epic R3D.

    R3D Data Manager does reliably copy your red media in my opinion, but I don't think it's absolutely fool proof. I've found wavelet corruptions that were not caught by R3DDM but found using RCX while transcoding. That said, it does give me pretty good piece of mind that things are copying correctly (i.e. whatever's present on the card...no issues with cables or errors from readers).

    well no md5 checksum software can catch corrupt frames unless the corruption happened in the copy. it would still catch it in that cause because the checksum wouldn't match with the loss of data in those corrupt frames. no software can account for something like that. good old fashioned QC by eye is the only way.

    i honestly find that with updated OS's and connections, I haven't seen a copy error in ages. ESPECIALLY with esata. it's been the most stable connection thus far, and I still do checksum on set as a safety net, but my own personal use, I've copied 10's of terabytes via finder with not a single corrupt file. I found that it happened a lot more with usb drives, especially on older OS's, like OS leopard. and I think that's really where the scare first cropped up. has anybody seen copy errors via copy paste in snow leopard and above via esata?

    Are you saying that the corruption was not on the RedMag, but on the copied Data only?

    I have seen R3D Data Manager report copy errors. Which is fine, because it's one-button-click to re-attempt those errors, and it fixes them.

    Conventional wisdom is something like you'll see a corrupt file transfer 1 in 10,000 files. But boy does it suck when it's the one shot you nailed perfectly. And of course that's the shot you will lose.

    Checksums take more time than just a simple transfer. But they tell you that every bit (each one and zero) was copied over correctly.

    They will NOT tell you if you overexposed your image, or if there is a corrupt frame on a shot on the Mag, or if there is artifacting . . . they only care that the ones and zeroes on the Mag are the same and in the same order as those on the destination drives. Problem on Mag? Problem on Destination drives.

    R3D Data Manager can be fairly automated. You can configure it to auto-start copying as soon as you insert the mag - to predefined target directories (up to four) and eject or erase mags once the copy and verification is complete. As others stated, it will not alert you to corrupt source. It will copy the source file bit-for-bit, provide you with detailed reports, alert you to any errors and give the option to retry only error files. You still need to visually analyze the footage.

    This is what I don't understand. If the corruption is on the RedMag then it doesn't matter if you visually check the
    copied data, because there is nothing you can do about it....unless you mean check it so that you can
    re-shoot the shot that is currupt?
