Hi,
This is the second time I've downloaded this file. And, winrar says it's
corrupted, when I try to extract it. What's the reason? Any clue? We've
severe electricity disruption here in Bangladesh. So, I often have to stop
and resume download.
I've tried to recover .zip file with some recovery tool and it has a
'sage-vmware-4.4.alpha0.vmwarevm' folder which is 3.49 GB.
Can anybody help on this?
Thanks in advance
Is the md5 checksum correct? Assuming that the file sage-vmware-4.4.alpha0.zip
then the md5 checksum should be: e13ba46d999a6ff0da3b9d58ae909ed0 You can get
free tools to compare an md5 checksum on windows. There are also some commercial
ones, which offer no advantage as far as I can tell. The free version did
everything I wanted.
If the md5 checksum is wrong, there's not much that can be done about it, other
than you download it again.
One possibility is we could split the file, then you download each part
separately. Then the md5 checksum of each part could be checked individually. If
one gets corrupted, only that part would need to be downloaded again. You would
of course need to rebuild the constituent parts.
Assuming I used the default names for the parts, (which are xaa, xab, xac, etc),
then you would re-create the zip file using the following,
$ copy /b xaa+xab+xac+xad sage-vmware-4.4.alpha0.zip
(this assumes there are 4 parts. But I can easily split it into as many parts as
you want).
If it will help, I could split the file and give you the md5 checksums of each
part. Note, that no part would be a zip file - it would only be a valid zip file
once all the pieces are put back together using the 'copy' command in Windows.
But it may allow more reliable downloads if you connection is poor.
Let me know if you want that, and what size parts you want the file split into.
Note, I could only do this on a server in the USA - you would have to download
from there - not from whatever might be your nearest local mirror.
