The specifications of the Plextor PX-755A state that the drive is able to write CD-R discs at 48x and CD-RW at 24x. Let us find out how the drive really performs in speed and quality.

Writing Data CD-R discs:

For our data writing tests, we simply set up a new compilation of 703Mb using Nero Burning ROM software. Writing method used is DAO (Disc At Once), and the disc is set up as a non-multisession disc with 'finalize disc" enabled. The screenshot below shows how long it takes to write a disc at the highest speed. (48x):

The drive took 2 minutes and 43 seconds to write the disc at 48x. Let us see how this compares to other drives in the table below:

Write Quality:

We will test CD-R discs from many different CD-R manufacturers. To really measure the write speed, we used the 'create data CD" function in Nero CD-Speed. The discs were written at the maximum speed that the drive supports. For the quality test, we used K-Probe 2 which is a tool developed by a Lite-On employee. It runs under Windows and works with drives made by Lite-On. Also note that different drives and different reading speeds may affect the results obtained when scanning the discs. We used a Lite-On SOHR-5238S drive with firmware 4S09 and scanned the discs at 48X speed.

A written CD-R disc will always have some C1 errors; C1 errors are easily corrected by the drive's error correction capabilities. The next level of errors is C2, while C2 errors could also be corrected by most drive's error correction capabilities; they are not wanted on a good quality disc. A good disc should not contain any C2 errors, and preferably have an average C1 error amount of below 2.0 for the best discs, or at least below 10.0 averages for good quality discs. After C2 errors, there are only un-correctable errors that will make a disc unusable.

I own this drive. Overall very satisfied. One issue up till now: I burned a CDR Audio disc with Nero (7.x latest version), by dragging some MP3 files to the audio disc. Although the disc is readable, it has a lot of hickups in the audio, which are also shown in the mm:ss indicator. Tried two burning speeds (48x and 4x, does not want to burn slower speeds) on Taiyo Yuden media that always worked in previous burners.
I am undecided if this is related to the drive or to the software. Need to do more coas^H^H^H^Htesting for that :)

Could be Nero, version 7 has been known to be having some problems producing glitch free audio CDs from mp3s. Unsure whether the latest version (7.0.8.2) still suffers from this or not.

Hi,

I've got this Plextor PX-755A DVD drive as well now. But I've got some problems.
CD's and DVD's read very well, no probs there. CD's also burn well. But when I try to burn DVD's the burning software locks up and the drive doesn't want to give my DVD back.

I searched the whole net for this problem but didn't find any solution for this problem.

Specs:
Intel P4 1.8 GHz
2*515 DDR-SDRAM
MSI MS-6547 main board
win XP Pro SP2
Burn programs: Nero 7 / Plextools

When I try to burn the burning begins well untill the amber light of the 755A starts to flash. Then the burn % meter stops. After 2 minutes the amber light stops flashing and turns green.
Now IE7 is stuck, burn program is stuck, DVD is stuck. The only way to get my pc running again is Ctrl+alt+del and stopping the burn program. IE7 still doesn't do a thing and my DVD is still stuck. Pressing the start button for a moment shuts down my pc and then I can start my pc again.

Anyone got some pointers for me?

I'm the owner of a Plextor PX-755A drive and I'm overall very satisfied of it. Burning and reading goes perfect except for one part, the drive doesn't erase most of my DVD-RWs and DVD+RWs correctly and makes them useless. I'm using Nero 7 with the default drive firmware and tried with Sony DVD+RW and Philips DVD+RW discs, most of both were erased incorrectly. I'm currently installing Nero 8 and looking for a firmware upgrade and hope to get this problem resolved.
