you must be kidding me...
[root@localhost internet]# dmesg |grep RICOH
hdd: RICOH CD-R/RW MP7083A, ATAPI CD/DVD-ROM drive
Vendor: RICOH Model: CD-R/RW MP7083A Rev: 1.20
I bought this cd a year ago, and I can tell you that it sucks ass. from day
one I had this problems (windows 9X, 2000, linux several kernels need to
reboot, XP does not recognize it). Apparently the driver itself is locked up
due to bad engineering, and rescanning the IDE bus will not help since the
drive is messed up. When in doubt boot when it's a ricoh problem.
2 days after I bought it, I changed it since it locked up the cdrw and the hd
which was connected to the same ide bus.
Lately I started having DMA problems in this cdrw and my cdrom ("IDE/ATAPI
CD-ROM 52XS, ATAPI CD/DVD-ROM drive" is it's name) and I fixed them using
"hdd=nodma" in the kernel parameters. In the 2.4.19 kernel there is an option
(IDE/ATA/MFR/RLL SUPPORT -> Enable DMA only for disks) for disabling which
does not help me.
Here there is a nice link in this subject:

BTW: Shlomo, I cannot burn with this drive in more the x4 altough I have a
re-writable media which claims to support it. The drive itself /should/
support it. What is your experience?
