I noticed that the current version of sccWrite (the one in 126.96.36.199) is still exhibiting Bug 304.
Is Bug 304 causing any issues with you? There is a beta version that fixes this issue. It's called
sccWrite_bug304.bz2 in http://marcbug.scc-dc.com/svn/repository/tarballs/
This beta version is much larger than the release version because it was built with debug symbols.

Here is the bug.
$ sccWrite --mpb 0 8 65282
ERROR: The given address 0x8 is not 64 bit aligned!
Try again with 64 bit aligned address (e.g. 0x0)!
But 0x8 is 64-bit aligned.
I can see the write occur with sccWrite_bug304.
