This 840g is way to complicated to set up. I had the 420N and it was a DREAM, so I upgraded.
It worked fine for about a week. Then it started. Could not write end of disc at once. Called tdk tech support. Made about 25 new coasters. Updated Adaptec stuff. Updated to V1.04. Got their cleaners, 'cause TDK only supports Roxio (which is lame), but, they had me trouble shooting in both Roxio and Nero 6. They had me put in fresh installs of XP PRO several times to make sure I had each program completely uninstalled. Had me change around the IDE configuration of my drives. I swear. I rebuilt this computer about 15 times in 6 days.
I liked the 440 so much that I bought two of these 840's. I took one back yesterday to CompUSA. If THIS burn I'm doing now does not work - I'm taking this one back today (within the 14 days) and I'm getting PLEXTOR or SONY. Wait about one minute and I'll tell you this drives fate. tick tick tick.
Okay - UDF Anchor Volume Descriptors - dumped th used read buffer - and I have my first good disk in 7 days !!!!
I gotta tell ya. This is bull. You should not have to do this stuff in this day and age when you set up a machine. Now, how long will it work ???
Ya know. I'm a bit angry right now, so, I'm taking it back anyway - and getting a SONY or the 880 model ! The 840 sux !

Once I got this player working right, it has been a dream. I can backup all sorts of discs using just DVD Shrink and Nero.
However, it was difficult for me to get working right. I had an issue right off the bat with the drive with it saying everything was unreadable. After installing the included adaptec software, this was fixed. Then, nero didn't like the drive and had errors on finishing burns, so I needed to upgrade nero. Then, I realized the drive was in PIO mode instead of DMA which caused the drive to read and burn very slowly (4-7 times!) So that an 8x burn took 45 minutes. (to fix, uninstall your IDE channel where the drive resides in device manager and reboot, make sure to select DMA mode before you reboot)
Now, I can burn fast and everything is working great.

I just got this burner and it came with 1.03 firmware. I tried to burn 8x on Memorex 4x DVD+R media without success. I upgraded to 1.04 firmware and I've burned the same disks at 8x without a problem. I also use this along with my LaCie 52x CDRW. TDK makes a nice burner.

I have used the following media: MEMOREX, SONY and PHILIPS. All have successfully burned movies. I was able to burn at 8x using MEMOREX and SONY; the PHILIPS was rated at 2.4x.
I did not upgrade the firmware. I did upgrade my software, CopyDVDPro (CopyToDVD 2.4.16). However, when I used another MEMOREX disc, it only burned at 4x. After talking with the software tech support, they said 8x burning will be hit or miss. If the media supports it, it will work if not it won't. This can be DISC BY DISC basis.
Overall I like the drive. Good features. I the fact that the TDK drive has two 6 pin FireWire connectors (external model). Plextor had one 4 pin and one 6 pin. Though the Plextor model was cheaper ($30 cheaper at Best Buy).
I haven't rated it yet because I am still trying it out. Haven't done everything with it. Have burned movies and copied CDs. So far that was successfull.

Okay, here's an update on my +RW writing dilemma.
I've discovered that Fuji 4x +RW's (RICOHJPNW11) write and erase properly in Nero 6.3. This is when using v1.04 firmware in the drive. However, I've also found that when burning the Fuji +RW as an ISO or data disc, you have to burn at 2.4x speed otherwise CRC errors occur in some of the files. DVD Videos on the other hand burn perfectly at 4x...Go figure.
So in summary TDK -/+R work great, the 4x rated +R's will burn at 8x, and Fuji +RW's burn good at 4x for video and 2.4x for data. And of course I haven't had any problems with CD-R's or CD-RW's, see my other post somewhere below.
AVOID IMATION DVD+RW's! They don't erase reliably! It's not a problem with Nero. I just tested these Fuji's by writing and erasing them about 7 times (in Nero 6.3) and they work fine. There's something wrong with the Imation compatibility. I couldn't erase any of the 10-pack I bought even on the first attempt.

I got a great deal on this drive at Staples for only $130 after $40 rebate and $30 Staples coupon. Out of the box I burned 4X TDK +R media at 8X using Roxio. For a short time it varied between 5X and 8X then settled in at 8X for the rest of the burn. Also burned 2X -R media at 4X and 2.4X +RW media at 2.4X. Very fast burning CDs too. No coasters at all. I did the upgrade to V1.04 from the TDK site but have not yet noticed any differences. Normally I'd give this drive a 9 because it would be nice if it would burn -R at 8X too. I went with a 10 because I don't want to drag its score down. Great drive.

Ditto on DVJones' comments about Nero 6.3, the 1.04 firmware and erasing rewritables. I tried erasing a memorex CD-RW with
the above setup and I get the exact same error. I'll try using different burning software than Nero and see what happens.
Otherwise, I'm pretty happy. Its fast and has otherwise been pretty reliable. I did coaster a few TDK DVD+Rs at 8x speed with the older firmware. Fuji's of been flawless, though.

Purchased this drive and I guess I would love it if my computer would not continue to restart due to a so called driver problem. I would love to make this drive work instead of going back and forth with many.

This TDK is a rebadged Plextor 708A. It just does not use the same firmware from Plextor.

Make sure you upgrade to firmware v1.04 (as of this writing), it allows between 5-9x rip speed without doing any tricks with the eject button. It also allows 8x burning on 4x media!! I use Nero v6.3 but I assume any burning program will go to 8x. Also, this seems like a no brainer, but make sure that if you are running DriveSpeed or a similar utility, that you set the read speeds to "maximum" before attempting to rip.
I love this burner. It works great with TDK DVD+R's and Imation DVD+RW's. I have had some problems erasing the Imations in Nero (I get a power calibration error), however they erase fine in other programs like DVD Decrypter. Strange.. This must be an issue with Nero 6.3 detecting the status of the media, or perhaps DVD Decrypter somehow forces the erase no matter what.
VCDs, SVCDs, data CDs, and audio CDs all burn just fine. I use Memorex CD-Rs and Memorex and TDK CD-RWs.
FYI, I play my DVDs and VCDs back on an old Sony NS-300 and they work great which kind of surprised me because of the age of the player.
Get this burner, you won't regret it. It's not worth saving the pennies for a junky burner when this one is just a little more expensive and is a solid unit that can do reliable 8x burns on 4x media.

I updated to firmware v1.04 and can still only rip at about 2.2x. This is in DVD decrypter. The drive is running in DMA mode, Win2k. I'm sure we'll figure it out eventually. This drive is relatively new and there's not a lot of user information on it out there yet.

Purchased this drive from Best Buy @ $150 with rebates.
With firware 1.03 burned great..would only do 4x on Memorex media though. Then upgraded to firmware 1.04 even better results. Just about to hack the plextores firmare. With 1.04 memorex and fuji burn at 8x :) takes about 7 minutes to complete. Unlocking the 2x read speed works on mine. DVD shrinks transfer rate goes from 2.4mb to 4-6mb.
YES THIS IS A 708a open up the insides and see.
Plextor makes these for TDK to sell at a lower price point.
Get it now before price goes up..Best Buy just raised it $60
Weird that my plextor cd burner can be unlocked just like the TDK!!!!!LOL :) :-) ::) :>) :<) :'(

This drive is working great for now. I recently updated the firmware to 1.04 from TDK's website and it resolved the stuck PIO mode problem that I had. Now I'm able to rip faster in DMA mode:
I 13:53:26 Operation Successfully Completed! - Duration: 00:17:55
I 13:53:26 Average Read Rate: 7,659 KB/s (5.5x) - Maximum Read Rate: 11,120 KB/s (8.0x)
For those having problems ripping > 2x should update to the new firmware and make sure "DMA if available" is set on the IDE ATA/ATAPI controllers - Primary or Secondary depending where your burner is connected.

I just burned my first DVD-R in lESS than 8 minutes using the TDK 840G. Earlier this week I purchased the Plextor PX-708A for the same price($299) as the better known TDK 840G. the Plextor burned but for some odd reason it would not even reach its 4X capability. I was disgusted so I returned it to BestBuy. 2 days later (after my debit was credited back :p) I purchased the TDK 840G. It burned the trial TDK 4X DVD+R in 7:55!!! ...4.7 gigabytes in 7:55!!!...I love this thing. This drive is NOT the same as the Plextor PX-708A, as some people were saying in earlier posts. Thanks for your time and if you need a GREAT burner then pick one of these baby's up!!!

I bought this one from Staples for 141.00. Installed and flashed the firmware to1.04 from Plextor. It works good and very quiet. But I had a problem: it start burning at 8x speed and then drop down and finished at around 15 minutes. I wonder why? Any help will greatly appreciated!
I think this is a major problem! :)

Haven't had any problems with it at all. Its fast and stable. I get much more compatible DVDs than with my old Liteon 401S. I'm pretty convinced that it definitely is a plextor 708a because not only does it have all the same features, but it also has the 2x rip limit, and you can get around it by holding down the eject button with the tray empty.

how come everybody keeps saying this drive is a rebadged plextor? i mean just because 2 drives look the same doesnt mean they are the same. Has plextor admitted doing business with tdk? anyway i have this drive as well and its a great drive

I haven't had a lot of luck yet with this drive. I have yet to burn a good +R disc. I've tried several different programs, including Nero, Burn at Once, and Copy to DVD.
I upgraded to TDK's 1.03 firmware. Where do you get the Plextor 1.04 firmware? All that I was able to get was an .exe file and a zip file that has a .bin file. Where do you find that 104.ini file to modify.
I'm new to the DVD thing and not sure what I'm doing wrong!

I also purchased the TDK 840G from Staples. Got home, installed the drive and flashed it with Plextor 1.04 firmware.
Tried to burn a Verbatim 4X DVD+R at 8X using Nero 126.96.36.199 = coaster. I then upgraded to Nero 188.8.131.52 and it burned like a charm, finished in 7:37.
Great drive so far!
