I'll I can do a test on the raspi , I've used the files on Raspberri pi is now synchronized !!
Glad you got your wallet up and running. I am still running the test with a bootstrap.dat file on Windows. It takes ages! Just using the regular block data files (not a bootstrap.dat file) only takes a minute or two, so I do not intend changing anything there. I would be inclined to investigate the issue with blkindex.dat on the Pi first. It is just possible (I suppose) that your original download of the snapshot.zip file was a bit dodgy somehow. During testing, I had to repeat the download a few times before getting a good copy due to network glitches, so I incorporated a number of retries into my downloading routine for reliability. Do you think this might have been a factor in your case? |

In my case the download is started without problems until the end !! I tried the two files to test even the Mac and wallet from the same mistake! I did download the .zip file! I can even make a try downloading the .exe file and try it on wallet windows !!

Interesting and thanks for that info. The snapshot.exe is built from the snapshot.zip file directly. I tried the snapshot.exe with Windows and it worked perfectly first time, so if you are able and willing to give that a try on your Windows machine, that would be a big help (and a sanity check for me). I am beginning to wonder if the format of the blkindex.dat file changes from one operating system to another - I honestly don't know. My first test using a bootstrap.dat file that I built using copy /b blk0001.dat+blkindex.dat bootstrap.dat did not work very well, so I am currently trying another bootstrap.dat using copy /b blkindex.dat+blk0001.dat bootstrap.dat to see if it makes a difference. |

I think that hosting an MD5 hash (or some other hash) of your snapshot would alleviate this issue, especially if you're automating downloads. Users that download it on their own can check the hash if they have issues and software that downloads the snapshot automatically can run a check to see if it got the correct file. If I had to venture a guess about the RPi issues, though, it might have something to do with RPis using BDB 5.1 by default (it might be 5.3 by default, if he's on the newest build). Since blkindex.dat tells BDB about the blockchain storage format, it's probably angry that it's trying to read the official client's BDB 4.8 index. |

Once again, very interesting stuff there. Thanks Feldenthorne. I take the point there about having a file hash to verify, but will not be going down that route. It would require extra work to implement and extra third-party software. It also takes quite some time to calculate a hash for large files, so that is one can of worms that I will not be opening  The Berkeley DB issue looks to be the clincher here. My second test with a bootstrap.dat file was equally unsatisfactory  It took over an hour to decide that it wasn't good enough and started resynching from about two months ago. I think I will stick to my original plan. Edit: Under Windows 7 64 bit on a fast machine (AMD 9590 4.7 GHz with 128 GB SSD system disk) it took 13 minutes from beginning a snapshot download to having a running wallet fully synched. Under Windows XP 32 bit on a slow machine (Celeron 2.1 GHz with 80 GB conventional HD system disk) it took 22 minutes to perform the same thing. Not bad at all. |

I test on raspberry , mac os 10 and windows 7 bit , extract the file .exe after on mac terminal cat blkindex.dat blk0001.dat > bootstrap.dat is ok for all !!
Perhaps it is better to release the file directly bootstrap.dat !!

I don't doubt that worked, but how long did it take to fully sync and was it synching from just two days ago? Did you try just using the blk0001.dat and blkindex.dat files directly under Windows 7, or did that not work? |

Hello, I have sent an email to the support team for Coin Magi but no one seems to be replying and no one on IRC seems to be able to help me either. I have attempted to register in the XMG pool for over a week now and every day it says that registration is disabled. Does anyone know when registration will open again? Or if there is another pool to mine from?
