What FS might be on this CD?
Hi Folks, I have a CD which was burnt using Windows Media Player on Vista. It carries a couple of directories with many (mostly PDF) files. When accessed with Vista, its contents are visisble and the files can be accessed. However, Linux doesn't want to know! For example: # mount -t auto /dev/hdc /media/cdrom0 mount: block device /dev/hdc is write-protected, mounting read-only mount: wrong fs type, bad option, bad superblock on /dev/hdc, missing codepage or other error In some cases useful info is found in syslog - try dmesg | tail or so and # dmesg | tail hdc: media error (bad sector): error=0x30 { LastFailedSense=0x03 } ide: failed opcode was: unknown ATAPI device hdc: Error: Medium error -- (Sense key=0x03) Unrecovered read error -- (asc=0x11, ascq=0x00) The failed "Read 10" packet command was: "28 00 00 05 7c 80 00 00 02 00 00 00 00 00 00 00 " end_request: I/O error, dev hdc, sector 1438208 Buffer I/O error on device hdc, logical block 179776 UDF-fs: No fileset found Any ideas?

Is your pdf reader up-to-date? The Windows version is up to, IIRC, 9 (Though IME the reader usually - rather, always - fires-up, even if it can't cope completely with a newer version of document.) Is there a Linux version of Foxit Reader? That might be worth a tri if there is. -- Tony http://www.users.zetnet.co.uk/hi-fi/

Thanks for the reply -- but the problem is not with the PDF reader. The problem is that Linux will not mount the CDROM -- with error message as detailed in my mail. In other words, Linux is not recognising that the CD has a valid filesystem on it. But Windows Vista *is* reecognising it (somehow).

Ah. Didn't wade through the detail - would I be cynical to think that it's a M$ ploy to make itself incompatible with the competition? -- Tony http://www.users.zetnet.co.uk/hi-fi/

Judging by the earlier comment and a bit of guesswork it might be that the CD has a bit of a "funny" udf filesystem on it. Adam -- jabberid = quinophex@jabber.earth.li

Is it some kind of "protected disk"/DRM ? Can you burn the disk using saner tools than Windows Media Player? Have you tried to read the disk in another Linux machine? Srdjan

Have you tried it in older Windows versions? Does the destination PC have a CD-RW/DVD-RW drive or just a reader? Is it definitely a CD not a DVD? (Made that mistake before!) If DVD, is it DVD-R or DVD+R? Or even dual layer? Can you boot the Vista PC from a Linux USB key and see if it will then read the CD, just to confirm it isn't a hardware compatibility issue? (Alternatively, I think some live CDs can be booted into memory and the disk ejected - Puppy?

From the keyboard of a Debian developer -
/Quote/ Try "mount -t isofs /dev/hdc /media/cdrom0". If it's from Vista, could it be in a Mount Rainier format? If so, he'll need a new-ish Linux kernel (more recent than 2.6.2). /End quote/ -- Tony http://www.users.zetnet.co.uk/hi-fi/

Hmmm: # mount -t isofs /dev/hdc /media/cdrom0 mount: unknown filesystem type 'isofs' mount: maybe you meant 'iso9660'? # uname -a Linux deb 2.6.18-6-686 #1 SMP Thu Oct 9 15:52:18 UTC 2008 i686 GNU/Linux (-t iso9660 doesn't work -- error message as before). "Mount Rainer Format" (mrw) not support by my kernel, it seems! More research necessary ...

UDF-fs: No fileset found
Following on from the hint I gave last night, have a look at: http://ascending.wordpress.com/2008/06/14/howto-read-vista-burnt-udf-dvds-on... Which is one of the first hits out of google for vista udf mount linux. Lots more useful looking stuff available too with those search terms, I'd suggest that and similar for working out what is going on. Note that the actual method of getting at the data looks a bit hackish and mentions that the guide will most likely not work except on the specific release of ubuntu they are talking about.

Thanks Adam. Interesting! And the comments seem to confirm that the new Windows CD-burner is yet more [<4lwd>[ing]] <4lwd>! At least it's a comfort to be reassured that my Linux is not failing to do anything it ought to be able to do.

Once again it's amazing how MS can mess around with a "standard". Hopefully this will start to backfire on them; there'll presumably be plenty of <=XP users stuck with this too? Anyway, there's a nice comment at the foot of the page Adam linked to: apparently Ubuntu 8.10 has the Vista UDF capability built in. I have Ubuntu 8.10 but no Vista DVD (nor even any Vista) to test with, is there anything I can easily check to confirm that upgrading to U8.10 is a "simple" solution for anyone stuck with this? -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0845 45 89 555 Registered in England (0456 0902) at 13 Clarke Rd, Milton Keynes, MK1 1LG

I can confirm that upgrading my desktop to Ubuntu 8.10 from Ubuntu 8.04 was simple. I have not yet tried half burning a DVD in Vista to see if it is readable in Linux. Tim.

To be honest, I'm not sure that they have messed with a standard. I think all it is that Vista by default creates filesystems that are UDF 2.5 which are supported in recent Linux kernel versions but I really don't know much about this given I only first did any research about UDF due to Teds problem. You can tell Vista to create discs based on older versions of UDF apparently that will be more compatible with older versions of XP/Linux. Although, don't ask me how as I've only ever used Vista for about 10 minutes. Hell, I'm not even sure if it will fix the problem Ted has been having, it might be a red herring :) Adam -- jabberid = quinophex@jabber.earth.li
