System freeze with CDRW
Hello to the Linux community.
I waded into Linux this fall for the 1st time and am sorry that I waited so long. The amount of learning has made it a struggle at 1st and now a real pleasure. I find Linux to be a great desktop replacement for Winblows.
I have tried to answer a couple of hardware questions that I could for others in this forum, now I would like to ask one please.
I have a Ricoh RW7083A 8X8X32 CDRW that mounts fine,
Shows up in the file directory as /mnt/cdrom2 (hdd)
but freezes the machine upon trying to read a cd. Anytime I try to access the drive with formatted media in it or with X-CD-Roast, system hangs. It will not freeze with blank unformatted media in it.
cdrom (hdc) is the cdrom, it works fine.
I have had it as a master on the secondary IDE channel, a slave, and the only drive on the secondary IDE jumpered as master.
I do get an error with it. When trying to access the drive with no media in it
mount: block device /dev/hdd is write-protected, mounting read only.
Root and users do have permission to view and modify content. I would expect to just get a no medium found error.
I ask this question to see what I am doing incorrectly. Other users have said this hardware to work with Linux. I am using Kernel 2.6.3-7. Mandrake 10.0
I have 2 HD's on the primary IDE, master and slave.
This is a Celeron 400 that I put together to learn Linux.
196 MB pc100
2- 3gig UDMA1 HD's
10/100 NIC
Sound Blaster compat. SC
cdrom
cdrw
Mandrake 10.0
Next will be trying to get 802.11b to work.

The drive works fine with winblows.
What have I missed here? Maybe Linux does not care for this hardware but I thought that I would ask first.
Thanks for letting me be a part of this forum and the open source community.
