to my suprise the 1640 was able to at least recognize the disks but I could not acess it with explorer. but with Ultra ISO and the 1640 I was able to retrieve the data from the disk and even burn it with CLoneDVD2 and walla!! they play perfectly. I am seriously impressed wtih the 1640 as a reader.
My stock Benq came with BSHB firmware and it read bad discs excellently.
However i have recently upgraded to BSJB and find that while the Write quality is the same for DvD +R 8x Media that i use - the reading quality seems to have gone down.
In particular i am getting read errors(for select discs) when i do a DVD copy using Nero Burning ROM when it creates the image. I was able to do this successfully earlier with BSHB with the same discs. The discs in discussion have been burned by some other DVD burner.
So my questions are:
Does the new firmware (BSJB) degrade the read performance of the drive.If no, should i try flashing the Firmware again.
While reading discs (especially those that are slightly scratched) the drive also seems to change the read speeds very often. (Accelerating and De-Accelerating) . Is this normal for a Benq.
Lastly are there any cons to repeated firmware flashing. For ex if i flash BJSB again or go back to BSHB. Will it harm the drive in any way..
