Hi there.
A couple of days ago I purchased the Samsung TS-H552U unit and installed
it on my PC (an old PIII-600,350MB RAM, 2 EIDE HDs and a DVD/CD-RW
Philips Combo 3210 drive) which is equipped with both Windows XP and
SuSE Linux Professional 9.3 (kernel 2.6.11-something - sorry, I'm at
work now and I don't have the full details).
This unit comes bundled with NeroLinux which I installed on my Linux
partition.
I checked the firmware version with the tool I downloaded from your site
and it's up to date (version US06).
The ATA peripherals are arranged as follows:
. 40GB HD (primary master)
. Philips DVD-reader/CD-RW (primary slave)
. Samsung TS-H552U (secondary master)
. 4.3GB HD (secondary slave)
Every unit is configured to make use of DMA (if available).
Under Windows, it seems I'm able to burn DVDs with the Samsung unit by
using either the Pinnacle suite or the Nero Express 6 one but under
Linux I'm unable to burn my home folder with NeroLinux.
NeroLinux recognizes both units (Philips & Samsung), it starts writing
to the Samsung one but, near the end of the writing process, it gives a
"Cannot verify data" error (sorry but I forgot to write down the exact
message).
Please notice that I expressely told Nero not to verify the DVD contents
so the above error message is a bit puzzling for me.
I've tried wit K3B as well but it bombed out during the recognition of
the units.
After the error message comes out, the DVD (DVD+RW) gets ejected, I can
remount it under a directory of my choice (eg, /mnt) and, after approx
30 to 60 seconds (why does it take so long to recognize the medium ? The
same goes for Windows) I'm actually able to see the contents of the DVD
and it seems the full directory tree is there.
The problem is that some files are not readable at all (a simple "cat "
gives an I/O error), some are readable but with a trashed content (eg, a
file which should contain some text now contains garbages) while others
are good (checked against the original ones with both sum and md5sum).
In other words, the burning is not reliable at all.
I tried by first fully formatting the DVD+RW disk but unsuccessfully.
I also gave cdrecord a try; the strange thing is that, under the above
situation, the "cdrecord -scanbus" only recognized the Philips unit and
__NOT__ the Samsung one. I had to use the "-dev=ATA" parameter to get
both recognized by I was unable to perform additional tests since the
verion of cdrecord I'm using is not DVD aware (today I'll install the
ProDVD version).
After some tests, I found out that by removing the Philips unit
everything worked fine; in fact, I was able to start K3B and burn my
home dir (approx 3.5GB) fine. I've also tried by verifying some files
with a script (it was too late for a full verify :-) and the
verification went fine.
Mind you that I used the very same CD+RW disk to perform the burning so
it should not be an issue related to the media.
I've tried by have both units on the same box with different EIDE/ATAPI
configuration but unsuccessfully; the removal of the Philips unit was
the only workaround I've found.
Have you ever experienced a similar situation ?
Thanks for your time!
Best,
Roberto
