Current DVD+RW/+R Drive/media prices - USA

2002-11-12 Thread Frank Hage
FYI:

For whatever reason, here in the US, it seems as if DVD+R is being more
heavily marketed than DVD-R. In last Sunday's newspaper adverts only +R
and +RW drives and media were being advertised, with the exception of the
Sony all purpose DRU-500A at $320.

Current advertised retail prices at my local (Colorado) computer chain
stores:

Memorex 2.4x DVD+RW - $200 (with $50 mail-in rebate)
HP 200i- $300

Philips 5pk DVD+R - $10, 5pk DVD+RW - $15   + cases
Fuji DVD+R 25 pk spindle - $50.

My personal price threshold for purchase at home has been $200.
Does anyone have any experience with the Memorex DVD+RW drives?
I'd be using both DVD and CD-RW media.

-Thanks.

One advantage I find is the ability to burn directly from NFS mounted
partitions. It's slow but it works well. I've got gobs and gobs of data
spread across many machines, many filled to capacity. It takes me less
time and a lot less work to cross mount our aging workstations and burn
directly than it does to copy and create iso files, and then burn. 

Other advantages are the ability to completely fill the disks ( 4 GB
iso files are a problem on 32 bit systems) and not needing free space
for the disk images.

Although its possible to pipe mkisofs output to cdrecord and avoid
producing an image, (which I usually do for CDR), buffer underruns
are a problem when the files live across on a NFS partition.

Of course, YMMV.

I don't think there's a standard. I think it depends on the player.

I recently purchased a cheap CD/MP3 player. It was somewhat picky about
how the disk and files were written before it had all its functionality. I
get good results writing 128Kbps mp3's on plain IS09960 (with 32 character
filenames enabled).  ID3 tags in the MP3 files are used to provide song
title and artist info as the music plays. My player has no problems
traversing directories. Names do not have to be 8.3  I organised my
files by artist/album/*.mp3 etc.

-Cheers,

Re: Write e2fs to CD

2002-10-08 Thread Frank Hage

: 
: How? Specifically, if I wanted to burn my /www subdirectory and all

: it, but I dont want that. I just want a copy of my e2fs /www on CD.
:

Korey,

It's not clear if your /www represents the root of a e2fs file system.
Assuming it does, here's all you need to do;

dd if=/dev/hdaX bs=32k | cdrecord -v -

(replace hdaX with your e2fs partition mounted as /www)


I often backup directories into tar files and then write those
to CD's using mkisofs, rather than running mkisofs on the directories
themselves. Tar files keep file permissions, ownerships, dates, etc and
allows for more flexibility when accessing and restoring files.

I'm curious, Why do you want an e2fs on the CD?  Few people would know
how to read an e2fs image file or CD.

I hope this helps.

Re: DVD-RW/DVD+RW

We are trying to assess the different DVD R and DVD RW technologies
for our own data archive needs. We bought a HP 100i about 6 weeks ago
and a 200i about  1.5 weeks ago. We're not experts. Our attempts are
based on methods described in various docs posted around the net.

Here's the results of our testing of the HP 100i and 200i Drives under
Linux. Note we have only tested them with small (1.5) GB data sets so far.

DVD+RW:

Both the  HP 100i and 200i will Write and Read DVD+RW.

 We used growisofs which uses a formating tool (dvd+rw-format) and
 mkisofs to create file systems on the disk. The output from mkisofs
 goes directly to the raw device.  cdrecord is not used.

 Most of our PC DVD-R's will read the DVD+RW disk. Laptop drives would
 not.  Data can be added to the disks using 'growisofs'', but deleting
 requires a re-format, and re-writing.

DVD+R:

ONLY the 200i will Write and Read DVD+R.

 We used mkisofs and cdrecord, much like we do for CD+RW.  The 200i is
 the only drive we can get to read the disks. No other drive we have
 (including the 100i) can read them.


My personal conclusions: 

DVD+RW: Useful. Drives are inexpensive. Media costs are medium.
Requires similar kinds of planning and scripting as multi-session
CDR's . Are usable on other drives.

DVD+R: Not currently useful. Drives are inexpensive, but only one is out.
   Few if any DVD drives can read these disks.

Here in the US, we are able to get the HP DVD200i (DVD+RW, DVD+R, CD-RW)
for $500.  We currently have had one for about 2 weeks and are in the
process of testing it. So far, so good.  We are now seeing how many of
our DVD readers can read these disks. 

They're also in stock at our local CompUsa stores for $499.99 

See: http://www.shopping.hp.com/   and search for dvd200i 
for more info on the drive.

Re: Question rgarding cdrecord -atip: Indicated writing power:

I want to determine the fastest speed I can write a CD -R which I'm hoping
can be determined from the atip output for Indicated writing power.
Not having access to a specification, I have sample disks indicating a
speeds up to 16x, but the atip output indicates a writing power: of 7.

My experience has been that I can specify speeds greater than that
allowed by the media or drive, and cdrecord will automatically  back
off to the max speed allowed. It's not clear what your concerns about
the Indicated writing power are.
