Greetings:
We'ed like to point out a few things we've noticed with the cyclad and other files
missing problem.
Just to get this out of the way. This problem plagues
legitimate copies of windows XP and Xp pro.
Here's what we've noticed.
#1: The cyclad... and other missing files occur in the install started from MS-DOS
or XP boot disk install including the /i386/winnt.exe technique.
#2: When upgrading from within windows 98, the errors of "missing (unable to extract)files"
does not occur.
#3: When viewing the drivers.cab file in windows 98 one can see and extract the cyclad
and the other missing files.
*Two out of the five* copies of windows XP we tested had problems with reading
the drivers.cab missing files (ex.cyclad,e.t.c.) and other driver & CAB MM files.
This includes viewing or extracting the files manualy in windows. Even if the entier
windows xp install cd is copied to the HD for quick installation. The missing files
problems still persists when done by (fresh install) ms-dos or xp boot/install floppy
disk.
As far as we can determine. There are either weak sectors on the windows
xp install cd's , or the dirver.cab was not properly compiled.
As for the no missing files when upgrading . It is conceivable that since windows
98 can read the cab files correctly and retries several times over to read a file
. It is possible that the cyclad and other files are perhaps crosslinked or just
bad cab files and windows 98 is able to recover the weak data.
One person did comment to us that they didn't have a problem with the the missing
files when running under an NTFS OS &partition, granted this may be possible. However
our NTFS OS & partition test resulted in the same number of missing files as with
a fat-32 partition.
We did notice a difference when we installed and used a much slower/older cd-rom
drive. 9 missing files instead of 14.
Our best guess is the "weak sectors" theory. As slower/older cd-rom drives tend to
produce less of the missing file errors. However it does not explain why a cd-writter
with it's more advanced /accurate reading abilities
is not able to read the weak sectors as well while in Ms-dos or NT/XP boot OSthan
an old ex. 12x cd-rom drive. Unfortunately there is very little that can be done
to undo the dammage to the data in the weak sectors.
The missing/unredable files is also rather unstable. It's not
always 14 files, it could be 11, or 3, or 15.
In other words MS got a bad batch of cd's or the master was defective when making
thier copies.
Nextly we can't confirm this. However it is possible that if one has smartdrive running
when installing xp from dos that
it could casue these errors. Though we've never seen evidence of this. We can not
confirm the effect of smardrive on Xp install's own cache.
Also setting the cd-roms to mode 2 in the cmos/bios did provide a marked improvement
in the number or missing file errors. We agree that this is odd . However it only
makes sense when a fast cd-rom/writter is used on an older computer system .
We hope this helps.
