 Posted: Sat Sep 29, 2018 9:47 pm Post subject: I think Gentoo may be seeing my DVD as a CDROM |
 |
|
| Code: |
# uname -a
Linux fir 4.18.9-calculate #1 SMP PREEMPT Thu Sep 20 14:36:36 UTC 2018 x86_64 AMD Athlon(tm) II X4 640 Processor AuthenticAMD GNU/Linux
|
I have the following two DVD burners. Both have always worked. I have used them as recently as yesterday. Although I mostly just use them for CDROMs.
NEC DVD RW ND-2500A
Optiarc DVD RW AD-72805
Can I check to make sure Gentoo sees these as DVD RWs?
I use both Windows and Linux.
Microsoft offers a 90 day evaluation of Windows 10 Enterprise. I would like to give it a try.
I download the ISO. It takes up 3.6GB on my Linux drive.
I have a stack of 4.75GB DVD-Rs. They are HP 16X speed. I have tried several different DVDs. None of them work. I get the same error every time - described below.
I have tried Brasero and XFBurn, neither work. Neither will burn the image to a DVD. Neither allow burning the ISO to a flash drive.
I get this message with XFBurn: Failure: Cannot reserve track of 3577944064 bytes. I get a similar message with Basero. This does not seem to make sense. There should be enough room on a 4.75GB drive.
I know that a lot of people have problems burning the Win10 ISO. Those people seem to be always be using Windows.
I have tried using a flash drive. Neither Brasero or XFBurn will work with a flash drive. So I formatted the flash drive to NTFS, and extracted the ISO files to the drive. I read a post that claimed this would make the drive bootable, it doesn't.
The extracted files, on the flash drive, take up about 3.5GB. Again, this should fit on a DVD.
I tried using an XP box to make a bootable flash drive, that does not work either.
Is there any way to burn a bootable ISO image on a flash drive using Linux? I have heard that Ubuntu has an app for that.
Supposedly this will made a bootable flash drive, but it does not seem to work:
| Code: |
# dd bs=4M if=image.iso of=/dev/sdb
|
Full instructions here:
https://www.linux.com/blog/how-burn-iso-usb-drive
The files are there but it won't boot.
Supposedly it can be tested like this, I tried it, it did not work:
| Code: |
# qemu-system-x86_64 -hda /dev/sdb
|

try unetbootin, if that doesn't work there is also a gui app called etcher that might work.

walterbyrd,
Put your dmesg output onto a pastebin and post the link here.
The important bit is . Thats the driver for all optical drives.
The drive capacity is not determined until you insert a blank disk.

Cannot seem to find etcher. But unetbootin seems to be installing.
| Code: |
# emerge etcher
emerge: there are no ebuilds to satisfy "etcher".
emerge: searching for similar names...
emerge: Maybe you meant any of these: dev-haskell/either, www-client/fetch, x11-terms/eterm?

Here is the link to my dmesg: https://pastebin.com/LrhJg4c9
Here are a few messages that include scsi3-mmc
| Code: |
[ 1.698699] sr 0:0:0:0: [sr0] scsi3-mmc drive: 48x/48x writer dvd-ram cd/rw xa/form2 cdda tray
[ 2.287215] sr 4:0:0:0: [sr1] scsi3-mmc drive: 40x/40x writer cd/rw xa/form2 cdda tray
|
From the looks of it, it found at least one DVD-RW drive. But neither seem to write to a blank DVD-R. I have tried several blank DVD-Rs.
If I put in a blank DVD-R, and I get that error message about not enough tracks, is the blank DVD-R ruined? |

Hi,
did you already try my shell command line proposal from linuxquestions.org ?
| Code: |
xorriso -as cdrecord -v dev=/dev/sr0 -eject /path/to/win10isoimage.iso
|
If it fails, please show the program's messages, as far as you
can scroll back in your terminal window
And yes, the drive "sr0" "Optiarc DVD RW AD-7280S" in your dmesg looks
indeed like a DVD writer. (It cannot be very young, as Optiarc closed
the shop a few years ago.)
Whether the image is supposed to boot from USB stick depends on the
existence of a Master Boot Record at the start of the image.
Is this image available for free (and without registration of real life
info) ? I'd like to have a look.
Else post the output of
| Code: |
dd if=/path/to/win10isoimage.iso bs=512 count=1 | od -t x1
|
If the result is
| Code: |
0000000 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
*
0001000
|
then there is no MBR, and thus no boot code and not EFI System Partition.
In this case you will have to unpack the image into a filesystem on the
USB stick. (Program "Rufus" comes to my mind for that job.)
If the last two reported bytes are "55 aa", then there is an MBR, and
probably the "dd" method should work.
Have a nice day 
Thomas |

walterbyrd,
This is a DVD drive
| Code: | [ 1.660473] scsi 0:0:0:0: CD-ROM Optiarc DVD RW AD-7280S 1.01 PQ: 0 ANSI: 5
[ 1.698699] sr 0:0:0:0: [sr0] scsi3-mmc drive: 48x/48x writer dvd-ram cd/rw xa/form2 cdda tray
[ 1.698701] cdrom: Uniform CD-ROM driver Revision: 3.20
[ 1.698872] sr 0:0:0:0: Attached scsi CD-ROM sr0 |
and so is this
| Code: | [ 2.267502] scsi 4:0:0:0: CD-ROM _NEC DVD_RW ND-2500A 1.06 PQ: 0 ANSI: 5
[ 2.287215] sr 4:0:0:0: [sr1] scsi3-mmc drive: 40x/40x writer cd/rw xa/form2 cdda tray
[ 2.287401] sr 4:0:0:0: Attached scsi CD-ROM sr1 |
Not all DVD drives can write all DVD media ...
The NEC supports.
| Quote: | Supported Media Types
CD-R, CD-ROM, CD-RW, DVD+R, DVD+RW, DVD-ROM |
Note that DVD-R media is not listed.
The Sony says
| Quote: | Supported Media Types
CD-R, CD-ROM, CD-RW, DVD+R, DVD+R DL, DVD+RW, DVD-RAM, DVD-ROM |
So you have two DVD drives, neither of which can write on DVD-R media.
-- Edit --
| Code: | | [ 1.210157] usb usb2: Manufacturer: Linux 4.18.9-calculate ehci_hcd |
You should have told us that you are not a Gentoo user but as this is a hardware issue, its distro independent, I'll leave the thread here.
Even Windows can't write on DVD-R media with your hardware.
If you are very lucky, there may be a firmware update for one or both drives to add DVD-R compatibility.

Hi,
The presentation on the page about the Sony is inconsistent and a lack
of DVD-R support would be very unusual for a drive in the Optiarc era
of 2006 to 2013.
No DVD-R burning on a SATA-attached DVD burner would be an anachronism.
The linked page says "Write Speed 24x (DVD±R)" and
"Rewrite Speed 6x (DVD-RW)". The NEC page says "Write Speed 8x (DVD±R)"
and "Rewrite Speed 4x (DVD±RW)". Both pages say "disk-at-once", which is
a write type of DVD-R, DVD-R DL, and unformatted DVD-RW only.
The Source of information for the "scsi3-mmc" lines in the kernel log
is the SCSI/MMC mode page 2A, which has bits to indicate read and write
capabilities for DVD-RAM and DVD-R. This page is so old that it knows
no other DVD or BD types. It was deprecated in 2004 when MMC-4 came out.
My modest workstation's collection:
| Code: |
sr0: scsi3-mmc drive: 40x/40x writer dvd-ram cd/rw xa/form2 cdda tray
sr1: scsi3-mmc drive: 48x/12x writer dvd-ram cd/rw xa/form2 cdda tray
sr2: scsi3-mmc drive: 40x/40x writer dvd-ram cd/rw xa/form2 cdda tray
sr3: scsi3-mmc drive: 48x/48x writer dvd-ram cd/rw xa/form2 cdda tray
sr4: scsi3-mmc drive: 0x/48x writer dvd-ram cd/rw xa/form2 cdda tray
|
All five drives can write all commercially available DVD types.
One can determine the promised device types iof a drive by a run of
| Code: |
xorriso -outdev /dev/sr0 -list_profiles
|
which for my sr0 says
| Code: |
Drive type : vendor 'HL-DT-ST' product 'BDDVDRW GGC-H20L' revision '1.03'
Profile : 0x0040 (BD-ROM)
Profile : 0x0050 (HD-DVD-ROM)
Profile : 0x0012 (DVD-RAM)
Profile : 0x0011 (DVD-R sequential recording)
Profile : 0x0015 (DVD-R/DL sequential recording)
Profile : 0x0016 (DVD-R/DL layer jump recording)
Profile : 0x0014 (DVD-RW sequential recording)
Profile : 0x0013 (DVD-RW restricted overwrite)
Profile : 0x001A (DVD+RW)
Profile : 0x001B (DVD+R)
Profile : 0x002B (DVD+R/DL)
Profile : 0x0010 (DVD-ROM)
Profile : 0x0009 (CD-R)
Profile : 0x000A (CD-RW)
Profile : 0x0008 (CD-ROM)
Profile : 0x0002 (Removable disk)
|
(Actually these are not media types but media roles. "DVD-R" means
"The drive can operate a DVD-R in its role as writable medium".
The role name of readable DVD is "DVD-ROM".)
Have a nice day

I unpacked the ISO file with 7z, formatted the flash drive with an NTFS file system, and copied the files onto a flash drive. I could see the MBR file, but it would not boot my laptop.
The problem may be with my laptop - an older HP G62. I went into the bios and changed the BIOS to boot from USB first. But I still have to hit the <esc> key while booting, or it will boot from the HDD. When I hit the escape key and choose boot options the only choices I have are HDD or internal DVD.
When I have the flash drive plugged in, it will start flashing when I turn on the power. |

Hi,
> xorriso is not on my system. I cannot install it with emerge.
Google ... well, there is "libisoburn", of which xorriso is the command
line interpreter. Try whether this installs a xorriso binary, probably
/usr/bin/xorriso.
Google also proposes me to run
| Code: | | equery b /usr/bin/xorriso |
to find the package.
(Else, you could build GNU xorriso from source. But let's first see what
Gentoo can do for you.)
-------------------------------------------------------------------
The image showed all zeros in its first 512 bytes. So it is not a bootable
hard disk image (like e.g. gentoo-livedvd-amd64-multilib-20160704.iso is).
The MBR program of a freshly formatted USB stick will at best look for a
partition with boot flag and try to run its Volume Boot Record as program.
That program would then start the appropriate programs from the NTFS
in the partition. This chain of booting needs expert preparations.
As said: Rufus comes to my mind.
Have a nice day

But it did boot.
Seems to be working, but I cannot explain why.
I decided to try and write a 4GB video file to the DVD. I used xfburn, and it worked.
After that, I tried, yet again, to burn the Windows image. To my surprise, it worked. I put the DVD into my laptop, and it booted. I am trying to install now.
Thanks for all the help. I am sorry to have taken your time.
I promise: I tried over and over, with both drives, and with both Brasero and xfburn, with several different DVD-Rs. I kept getting the same error message. Then today, after writing the video file, it worked. |

Hi,
it is a little miracle that DVD burning suddenly worked. (Sometimes it
needs just a few bystanders who have clear ideas what should work.)
The fact that it boots from DVD without having an MBR is no miracle.
BIOS and EFI boot optical media via the El Torito boot record.
(It sits at DVD block 17, bytes 34816 to 36863.)
Have a nice day
