I purchased the TDK 840G DVD +/-RW 8X about 2 months ago.
During that time I have used this burner with various medias and software. More than 90% of the time the drive did not perform adequately.
Problems have ranged from:
- Burn errors that resulted in coasters. I have a stack of them. I used various programs and media. So I am not talking about isolated situations.
- Slow recording speed. I compared it to my Sony DRU500AX. As an example, on a 4X-R, Sony will burn at a rate of 12 minutes per GB, whereas the TDK will take 18 minutes per GB. That translates to 50% slower.
- The TDK is supposed to burn at 8X. My most recent test on a Ritek 8X -R clocked at 1:42:26 to copy 4.21 GB. That represents 24 minutes per GB. Slower than 4X media!
- The TDK has problem recognizing (therefore reading or writing) certain media. Such as Memorex 4X +RW.
The media I have used are -/+ R and RW in 2.4, 4 and 8 X from Sony, TDK, Memorex, Ritek, Memorex and a few other names.
The software I used are Roxio, Nero, Instant Copy, DVD X Copy to name a few.
I have also upgraded the unit to the latest firmware (1.04). Which happens to be the second firmware upgrade in 2 months for a relatively new unit. Shortly after I bought my unit I started noticing retailers (stores and on line) heavily discounting the unit. Two firmware upgrades plus heavy discounting… you draw your own conclusion.
Let me also add that I have contacted TDK tech support on these issues. They have not been helpful.
This is from the latest email I received from them: "… you are using a 3rd party software, and we cannot really provide any support for them. The DRU-500 is a much older drive with better compatibility with different software packages on the market…â€
Again you can draw your own conclusion.
I am interested in hearing from other TDK 840G users. Have you encountered problems of any kind with this drive? What programs have you used successfully or had problems with? Same question for medias. Have you compared your unit with other brands?
Your contribution will be very welcomed.
