AOpen CRW5224 Problem

Postby bbwoolfy on Fri Aug 01, 2003 9:34 pm

I just bought the AOpen CRW5224 on the strength of the review @ BCC (http://www.benscustomcases.com/reviews/Aopen5224/) - which incidently is very good.

I've been putting the drive through it's paces - basically repeating all the tests in the review - and I gotta say I'm impressed.

In the read tests, I got better results than the review drive -

31.43x Average, 18.53x Start & 41.47x End @ 40x (Speed Boost Off)

and

39.87x Average, 23.45x Start & 52.68x End @ 52x (Speed Boost On)

- impressive! :)

Although the access times were 'slightly' slower. :(

However, when I ran the write test, with Nero CD Speed 2.02, everything went fine - up until around 10secs remaining. When the speed suddenly took a nosedive from about 52.5x down to around 16x! - the rpm also dropped from 11,000 to 3,500. But then the speed picks up again to around 33x - and the rpm to 7,000. Giving me a final time of 2m 35s - as opposed to the 2m 25s in the review! (for an 80min CD-R). :cry:

The final results are - 39.41x Avg, 23.41x Start & 33.26x End - in a time of 2m35s.

I've tried this test a few times with the same results.

Also, I do have DMA enabled and the firmware is v1.06. I also disabled any AV, Firewall, utility SW while testing, and don't have any other optical drives in my rig - just one HDD on IDE 0, 0 - and the CRW5224 on IDE 1, 0.

Does anyone have any clues as to why this is happening???

I'm sure if the speed didn't drop off at the end I would get burning times of 2m 25s or less.

It's the drive's write speed control technology at work. If it senses that the media cannot handle those speeds, it will kick it down to an acceptable level. I recommend trying other media.

Thanks Ian,

I thought it might have something to do with this.

One more thing I wondered about was, in Nero (5.5) when JustLink is activated it reports this in the burn progress window.

Should a message not appear to say JustSpeed is activated?

I have the OEM version of this drive, and I don't see the JustSpeed message. I don't think that it should appear in the Nero window.

@CDRecorder

What media would you recommend for writing @ 52x on this drive?

I've been using SpinX 40x media (made by CMC) with it, but I wouldn't recommend that media for long-term storage. Although I haven't tried it with this drive, I would recommend Fuji 48x media. :)

BTW, I have the firmware version 1.05 from the AOpen web site. I tried 1.07, but the write quality didn't seem as good, and I really don't like that Speed-Boost "feature" that was introduced with version 1.06. :(
