Re: [newbie] USB CDRW

2001-03-05 Thread Ed Tharp

I have a USB cd writer, I have not been able to get working under any flavor
of linux (altho I must admit I have given up on most flavors other than L-M.
I have been using 7.2. I do get a lot of buffer errors, more when I run
seti-at-home. I Strongly would recommend an IDE or SCSI burner.

 I don't know about the usb support on 7.2, your chances may be better on
the
 next release 8.0. With that said, from what I have seen and my setups I
went
 with two internals since I could get two for less than a usb or serial
 external at the time.  Here is the thing, data transfer on usb is supposed
to
 be high speed, but a cdrw can only handle so fast a speed as the buffers
and
 read will allow.  When a cdrw is designated a 4x4x6 for example: 4x write
and
 4x rewrite and 6x read  with the x standing for the speed = to 4 times
150kbs
 or 600kbs of data transfer for a maximum. So you see the usb is capable of
 the data transfers of most any cdrw but it is the cdrw speed that governs
the
 process. The other factor to consider is the buffer mem of the cdrw the
 higher the number the less chance of getting a bad burn.due to what is
called
 buffer overrun.  You now know everything that I know about cdrw's.  Hope
this
 helped or at least did not hurt. If anyone out there sees an error in my
 discourse please jump in here and correct me.  Good luck,

One more thing

The *only* benefit to the USB CD-RW would be portability, and you would no
doubt be paying a premium for that. If you don't plan on using the CD-RW
drive on multiple computers, I wouldn't bother with the USB.

RE: [newbie] USB CDRW

2001-03-05 Thread Franki

I have a USB burner,, have yet to fire it up in linux, but I think I can get
it going, particularly when I upgrade in a couple of months.. the burner has
a 4mb cache to make buffer underruns less of a problem,, and the drive is
really just a ide drive hooked up to a IDE to USB interface card. works
great in windows, and I think I won't have to much trouble when mdk 8 is on
the system, from what I have read anyway..

The USBdrive is fantastic in windows, and great because I can burn from my
laptop, or any of my servers, just by plugging it in... great for backups...

 I am debating to get a usb CDRW or get the IDE interior drive.  I have two
 questions:
   1.  How do I get my LM7.2 system to recognize the USB Burner
   2.  Any advice on which is the better buy...interior or exterior?

I don't think cd-writing on usb is a terribly good idea.. Could be wrong
though :)

   3.  What are the speeds 4x4x6...vs8x4x32, etc relative toI am
 having trouble
   understanding how to judge relative speedis a 4x4x6 fast enough ?

The first number is write-speed (cd-r), the second is rewrite-speed (cd-rw),
the third is read speed. 1x is the "normal" cd-speed, which is about 300
kps,
or 74 min to burn 74 min of music/650 mb data. Mulitply the speed by those
numbers. Ie. 4x4x6 means 1200 kps for both writing modes, which means about
18 min to burn a full cd. Reading would be at 1800 kps.

Keep in mind that your system must be able to feed the writer with data at
that speed (normally not a problem, but stranger things have happened),
unless it has burn-proof technology (pause writing on buffer underruns).
