If you're just having problem open your CDR drive, here the trick : Get a paper clip, unfold it. Now place its tip inside the little hole there's in the front of your drive. Push hard and the case will open.

I would expect so, but you'd have to use host header files and some sites would be served by one other sites by the other.

Absolutely, there's a Windows version of MySQL.

Don't you have access to your original files?
It looks like your CD hasn't been burnt at all.
If you've erased your files from disk, we'll have to help you get _those_ back.

Well memorex came out with a new media cd called, "Ultra Speed"  its different kind of cd-rw, and i burned my files on there with sony 700ul burner, that doesn't support this media, but it burned anyways, and now my other cd-burners won't read it because it doesn't have the ultra speed logo on them.

That is possible yes, and DVD-drives don't they support them to read? Are you also sure that your cd was closed after burning?

Ohh... Never heard of that.
OK, so your CD might have been burnt. Though we still don't know if it was done properly, since your burner doesn't support this.
So the question is : Do you still have access to your original data (ie. on your HD)?

I don't have access to my data on HD, i checked my sony dvd/cd-rw burner it says it supports ultra speed, but it shows nothing on cd, let you know i just erased my whole cd.  i wouldn't mind to see if we could recover them if possible!

I'm not much into recovery data from CD's
But if your data was on HD, there's something we can do.
Easy Recovery is an extremely good software for this.
Please note that you shouldn't write anything to the disk you want to recover data from.

That might be a good option, indeed.
In case your data was far from the beginning of your partition, you might still be able to get it back with Easy Recovery.
It's worth a try.

it can be that the recorded data is only readable with that software, so you could try installing that with another drive, or read the contents on a pc with this software installed.

I don't need to recover anything now, since i found my other cd, that had the files on it.  Problem is, if i burn a cd, there should be files on it, not a blank cd.  This only occures on 24x ultra speed cd-rw, but i was wondering, could i've picked up a pack of bad cd-rw's.  You know what i'm saying?!!

Many posts here, not trying to overwrite anyone else's comments ...

The FIRST thing to try is a burn to a NORMAL CD/R.  When (if?) you find that works OK, you will begin to see it is not the drive, hopefully.  Sony's are extremely reliable drives, in almost all cases.  I've had them outlast all other CD drives put together.  The problem is in the CD/RW technology, designed for older slower hardware.

I tried many CD R/Ws and could not get any of them to work in numerous drives, reliably -- they would in most cases freeze the system.  So I eventually threw them all away.  Once I went to CD/R only, all the system freezes disappeared and have not had a problem since.

CD rewritables are a bad idea with newer drives.  In my experience, they don't work.  For 10c per CD/R, you are wasting your time fiddling with RWs, toss them and go to CD/R.

There are so many issues here, I don't know where to start.

For starters, there are [at least] three totally different ways to write a cd:

1.  Explicit, writing with a burning application such as Roxio or Nero ("ISO writing")
2.  UDF of "Packet writing" (sometimes called "drag and drop" or "drag to disc")
3.  The very limited built-in CD writing capability of Windows XP

All of these are completely different, are done differently, and have different requirements (for example, UDF packet writing requires that the discs be "preformatted" before they can be used).  [And note, both Nero and Roxio include both ISO writing and Packet writing in their products].  I don't know what you did, or with what program, or how you did it.  Give me some more information and I'll try to help.  I'm VERY familiar with the Roxio products (Easy Media Creator) and for 4 years I was a beta tester for Corel / Adaptec / Roxio on their burning sofware.

Going a bit further, with one exception, I have to agree with sciwriter:  Don't use CD-RW, PERIOD.  Stick to plain, one-time-use CD-R.  You can get CD-R media "free after rebate" almost all the time, and it's never necessary to pay more than 10cents a disk for it.  CD-RW is notoriously unreliable.  Just forget that CD-RW exists and stick to one-time CD-R.

As for the exception:  Well, choice 2, above (UDF or "Packet writing") is normally done only on CD-RW media.  My comment there is also very simple:  Don't use UDF writing at all, ever.  Stick to standard "ISO" writing.  In fact, I recommend that when installing the Roxio or Nero product, that you don't even install the UDF/packet writing utilities ("Direct CD", "Drag-to-disc" and "InCD").  Packet writing creates non-standard (e.g. non-ISO) media that often can't be read on systems other than the one they were written on, or at least systems that have the SAME software installed.  You don't want that:  When you write to a CD, ESPECIALLY if it's for backup, you want a universally readable CD that can be read universally -- everywhere.  Which is one reason (and only one reason) that you should stick to "ISO" cd writing.

Anyway, I hope that this is helpful, tell me exactly what you did and how, and I'll try to provide more assistance.

Hey there,  I burned files to cd-rw 24x ultra speed using roxio easy media creator 7, and of course my cd burner has the ultra speed logo on it, so it should be compatible.  After it finished burning the cd and all, this cd-rw was still blank.  Weird?!!

Are you sure that the CD was blank and burnable (in particular, not formatted for UDF writing)?  Look in "Tools", "Disc and device utility" at the CD in the drive BEFORE you do the burn.

Are you sure that you didn't have "test" selected, which doesn't actually do a burn, but only "simulates" one to see if the drive is working?

Can you tell by looking at the CD if, in fact, anything has been burned to it?  (it's usually darker when it's burned, and if not fully burned, there will be a "ring" from the inside out, but perhaps not all the way out.  It's much harder to tell, however, on CD-RW).

Trying to figure out if it was never burned at all, or if it was burned but can't be read.

Well, then the CD WAS burned, obviously.  Now the question is, why is it unreadable.  Unfortunately, that is a far more complex question.  My first suggestion would be to try to read the CD on other drives, and in other computers.  You may find that the CD can, in fact, be read --- but not on that drive.  It happens, believe me.

Not just CD-RWs.  I have seen factory pressed CDs that could not be read in certain drives, drives that would read "other" media with no problems, and the CD that was unreadable in that drive coulld be read fine in other drives.  (in fact, the CD in question was for Easy CD Creator version 6, the original pressed factory Roxio CD).  But, at the same time, there really might be something wrong with your CD or your burner.  See if you can read that CD elsewhere.

Well, there are a lot of things that can happen to a CD to make it unreadable, including "it a packet-written (UDF) CD and you are trying to read it with ISO software", also a CD that was written but neither the CD nor the session was "closed" (usually, a CD-RW burner can read those, but a "plain old" CD-ROM (or even DVD-ROM) can't), and, of course, errors in either the media or the burner (you could just have bad media, or, if not bad, then incompatible with the burner).  Another thing, sometimes the media and drive are both ok, and not necessarily incompatible, but for whatever reason the "burn" is done at the wrong speed, too fast or too slow -- any given media can only be burned over a narrow range of speeds.  CD burning is kind of like photography, and the media can be "over exposed" or "under exposed" by the laser beam.  All of this is supposed to be handled automatically in most cases (unless the firmware for the drive has been "hacked" to allow manual override of the automatic settings), but with some combinations of media and burner it just sometimes doesn't work (as the write speed increases, the laser beam is "burning" each spot on the disc for a shorter and shorter period of time because it's moving faster.  But the laser power output is also variable, and is increased to compensate for this).

What I would do -- especially since these are RW media -- is do some test burns and see if they work.  If they do, fine, we don't know what happened, but we do know that this media and your drive work.  Conversely if they don't work .... then you know that and won't assume that a backup or archive CD is good when it isn't.

Also, as stated earlier, a serious recommendation here is just not to use CD-RW media at all, period.  Stick with one-time media (CD-R).   And even there, you need to do some test burns (yes, it will waste some media) to make sure that you have a reliable system and combination of drive/media before you end up having to depend on it.

If the drive is no good, by the way, and you need to replace it, there are only two choices worth considering.  The first is a Samsung "Combo" drive (reads DVDs and both reads and writes CDs of all types).  About $40.  Or, the other choice, a DVD burner, which will also read and write CDs, and the only choice there is the "Pioneer" drives, the A08 or A09 (sometimes listed as the 108 or 109)(the "9" models are the newest versions, but the 8's are fine).  These are the best DVD burners made, they are dual mode (+ and -) and dual layer (the "9" models will be upgradeable to do dual layer "-" media when it becomes available, the "8" models only do dual layer "+" media).  And they are relatively inexpensive (usually $80 to $90).  Actually, when I build systems, for people who don't mind the extra cost, I install one Samsung combo drive and one Pioneer DVD burner.  That way, we can do drive-to-drive copies of any type of media, either CD or DVD without having to buffer the entire media to the hard drive.
