AOpen CRW5224 Review Query
« on: July 29, 2003, 10:22:38 AM »
I just bought the AOpen CRW5224 on the strength of the review (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)

- very impressive!  ;D

Although the access times were 'slightly' slower.

However, when I ran the write test, everything went fine (reaching about 52.5x) up until the last 5-10secs, when the speed suddenly took a nosedive!!! Giving me a final time of 2m 36s - as opposed to the 2m 25s in the review!  :o

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.

Hey there, welcome to the Forum!

Yes, the AOpen 5224 is quite a good drive.  The difference in the tests (yours v.s. mine) is likely the result of using different media and/or having a different firmware revision.

Due to these variables, it is quite likely that every review done of the same model of drive will have different results.  I try to eliminate as many variables as possible, by using the latest firmware available, and using a designated stack of "review cd's."

As far as the nosedive is the write tests:  Have you tried using different media, or firmware?  Also make sure you have DMA enabled (yes it matters even for a simulation.)

I hope this helps.  If you have any more questions, please feel free to ask!

Hey Zeus, Thx 4 ur reply,

I had considered whether it was the media - the discs I'm using are Infiniti Compax 80min/730mb (although Nero's Disc Info ID's them as Ritek 97m15s17f CD-R, Dye Type 7: Short Strategy (Phthalocyanine) - whatever all that means. ???

They're marked as 32x but the manufacturer's website says they will handle up to 48x (www.medeainternational.com).

I haven't managed to find any the 48x media which you used - as the choice is pretty poor locally - so I haven't done the test with other media (I burned the AOpen 52x b4 I thought of testing it - doh!).

The CD Speed write test is really weird tho, as (like I said) it nosedives, at about 10 seconds remaining, from about 52.32x down to around 16x - the rpm drops from 11,000 to 3,500 also. But then the speed picks up again to around 33x - and the rpm to 7,000 ???

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

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.

Something else that's puzzling me is the drive's 'JustSpeed' feature. It's supposed to automatically find the optimum speed for burning to a disc, yeah? - but when I burned on one of the aforementioned discs, it let me write @ 52x - but yet the disc was read as a 'blank' disc afterwards, even though it was clearly visible it had been burned.

So something aint right - coz if the discs a duffer surely it hasn't burned at the optimum speed?

Incidently I can burn @ 40x no problem with these discs.

Phew - that was a loooong post! - hope it wasn't too boring  :)

Anyway, any advice u or n e one can offer would be appreciated.

Hmm.  I see the firmware you're using is dated February 28, 2003.  I was browsing their FTP and I noticed a later one, dated April 20.  It's 1.07, and you can download it directly by clicking here.

Let me know if this helps resolve your issues.

Thnx Zeus,

I'll give the firmware update a try.

Btw - when burning with Nero do u know if Justspeed should diplay a message during the burn process - u know, like Nero displays the message 'Justlink Activated' when justlink is on?

If anyone else has had problems similar to mine with the CRW5224 or any other drive - your advice/comments would be appreciated.
