been meddling with blockchain loading for several days,
inside VM and natively, got hdd overstuffing and
blockchan/index file damaged and all.
afterall i got 193000 checkpoint and topped it to last of 2013-JAN-30
6.5GB ain't no joke

anywayz, here my magnet is:
magnet:?xt=urn:btih:A501B62BEA0265413D76C58663BD0522D0FE91BE&dn=BLK-2013-01-30&tr=udp%3a%2f%2ftracker.openbittorrent.com%3a80%2fannounce&tr=udp%3a%2f%2ftracker.publicbt.com%3a80%2fannounce

sure it's no top security, but might help someone

feedback appreciated, someone might use uTorrent 'rehash' option to validate blk0001.dat, blk0002.dat, blk0003.dat
those are append-only ( not sure if blkindex.dat might be compared, try it too and post match % )

cheers

ps: if you keep those on NTFS, try 'compress' flag.
it gives me 0.57 GiB down, 6.46 to 5.89
