Hi!

I recently found out my laptop was compatible with Hi speed CD-RW (oh ). I subsequently bought discs from different makes: DataWrite and Memorex. I then decided to test them and crammed them with MP3s using NERO 5.5.10.50 at High Speed (X10). I used to write my "conventional" CD-RWs at X4 speed. I then listened those very promising little technological wonders with my Sony D-NE1 to see (hear) what the story was...

Well, I noticed a VERY significant loss of clarity or specific albums such as Radiohad's The Bends (ripped using EAC alt preset fast standard) or Malcolm Middleton 5:14 Fluoxytine (Lame 3.92, CBR 192 stereo)!! LOADS of clicks, skips, scratches, "wumps", you name it!! At times, the track would just simply won't play back and totally skip!? I listen to my Sony D-NE1 on the move, Jog Proof Protection 1. I used MP3Gain on all the aforementioned albums, Album Gain.

Besides, I NEVER noticed any such phenomena with standard CD-Rs or "Normal Speed" CD-Rws (4X Write Speed, Verbatim) which all yielded very satisfying results so far. As stated before, it wierdly enough occurs on only (thank God ) a couple of albums, be they CBR or VBR-encoded.

Have you ever experienced anything like that? Does it come from a compatibility problem between the D-NE1 and Hi-Speed CD-RWs, or MP3Gain, which I am just starting to use??

I will value your judgements, critics and opinions very preciously!!

Many Thanks in advance!

I own a Terratec M3POGo portable CD player which plainly sucks when playing (all kinds of) CDRW media ... it seems to me that transfer rate/track focusing does not work very well with this player's drive (using Verbatim RW media only), especially when using "jog protection" aka RAM buffering ... last but not least, seek times (and disc recognization) seem to be higher with RW media, too.

Normal CD-R media works very well, though ...

My Clarion car CD player does not complain about CDRW media at all ... bei it normal speed, high speed or ultra speed.

My solution to this would be ... check out if you can test another D-NE1 device from sony ... if the problem persits, you should not use RW media - a firmware update to your write device might also be of help.

I have recently bought a Sony D-NE511 cd-mp3 player.

Both 4x verbatim and 10x tdk cd-rw discs I have tried with it worked equally well.

My success has been hit and miss using Verbatim's Datalife Plus recorded at 10X and played back in my Alpine CDA-7893R with compatible CD changer. The problems arised after around 3 burns on two of these discs (one being really bad, I have five of them in total) with a Plextor 40/12/40A. I get the same pop, clicks sklurp mentioned above (it bloody hurts the ears too!)

The discs are labelled high speed only (8-10X) but burning them at 4x seems to have all but resolved the problems ... so far.

I find the vast majority of "High Speed" CDRW's are actually rebadged 4x ones, from what I can make out... That is, they simply do not burn at all well (Oodles of C2 errors all over the shop) at > 4x. That said, I do have some Packard Bell 12x Rewriteables which give lower C1 error rates (no C2) the higher the speed you burn it at

I really doubt it. The HS CDRWs are physically different, AFAIK.

I had one package of Samsung CDRWs (Plasmon), which burned faster than x8 gave C2 errors. At 8x they performed fine, with C1 rate below 20 (KProbe results).
