הנה כמה הודעות מדיון בפורום ב MandrakeClub. אני לא יודע עד כמה המידע כאן נכון אבל חשבתי שנכון להביא אותו לתשומת לבכם להשלמת המידע. כמו שתראו במצ"ב, החשד כרגע הוא שהבעיה נובעת מבאג בכונן היות וההגדרות שלו תומכות בתקליטורים המכילים עד 650M בעוד שהתקליטורים השני והשלישי של מנדרייק מכילים 700M. כנראה שהתעלומה תחקר לעומק בימים הקרובים.
נ.ב. "אחד" מכילה 550 MB כך שאם אכן הבעיה נובעת מהעמסת התקליטורים של מנדרייק הרי היא לא תשפיע על "אחד" אבל מומלץ לנקוט במשנה זהירות. למישהו יש כונן מהדגמים הרלונטיים כדי לבדוק אם "אחד" תצלה אותו?

I can't say I'd blame anyone for wondering about the validity of this thread....
I can hardly believe it happened, and I have one of the fateful drives in my posession.
So far as I can tell the problem is contained to LG (samsung) brand
CRD-84XX drives. Previously I had not heard of the problem
on other than a Dell GX1, but there have been more reports,
and it appears that it is on other PC brands as well, but so far only on
the Samsung CRD-84XX drives. The problem actually
occurs when trying to install Mandrake 9.2 from the CDROM.
I know that sounds strange, reading a CD and the drive fails....
maybe there is something to the notion that the LG drives cannot
handle the 700m disk size. At this point I am not going to
point the finger at Mandrake. It's altogether possible that
the LG drives have a problem that just now surfaces while
being used in a mode that isn't frequently used, and it's
also possible that the Linux kernel is the ultimate source
of the trouble. My personal leaning is toward a problem
with the hardware. It's unfortunate for Mandrake that this
problem surfaces with the release of Mandrake 9.2, but fortunate
for everyone else, because if any group can solve the issue, it's
the Mandrake team, and the followers of this great distro.
Does anyone know of any trouble with the LG CRD-84XX
drives reading greater than 650 megs?
------------------------------
I am not willing to say that LG drives are the problem.
However, many CD Roms by LG shows (specifications)
“User Data Capacity” is 650 MB.
The specifications did not specifically say that the
“Data Capacity” was limited to 650 MB.
The ones I have seen with these specs
were LG 8522B, 8520B and 8523B. I
also do not know if the specs have changed since
I have seen them.
Several OEM also might be using these drives.
I do not believe that the 9.2 ISO will damage a drive.
However, if a drive is not capable of handling a capacity
larger than what it was designed for, damage could occur.
The drive is not necessarily a bad drive it could be
simply not designed to handle more than 650MB of data.
Some early comments relating to capacity is on the right track.
---------------------
Here's a little follow-up on the 650
meg capacity of the LG CRD-8400B and
CRD-8482B CD ROM drives.
These are links to Dell.com
CRD-8400B:
http://docs.us.dell.com/docs/storage/6516r/en/spec.htm
CRD-8482B:
http://support.ap.dell.com/docs/storage/699yr/en/spec.htm
These spec sheets show the data capacity of these
readers to be 650 megs.
I would like to hope that a drive that cannot read greater
than 650 megs would not die
when asked to read a 700 meg disk.
Then again, when these drives were deisgned, 650
megs might have been all that was ever dreamed of on a CD.
Thanks for the great tip ViroMan!
As for me, I'm going to be sure to make sure drives
that are tasked with reading
a 700 meg disk, are designed to do it, and that's likely to
be the end of it. Would be really cool if there were
a way that disks with >650 megs
simply wouldn't be readable on the 650 meg readers.
