    i have a tsstcorp ts-l462d combo drive factory installed by my oem on my compaq presario c501nr notebook. i have a problem formatting cdrw media. only 554mb of 700mb availabele after formatting. i was told this was due to the creation of file allocation tables.

    however when i format CD-R media i have no such problem. all 700mb are available after formatting. it seems i can use any CD-R manufacturer's media.

    please explain why there is such a difference between formatting cdrw vs, cd-r media.

You will never be able to format the entire 700MB of any RW media. This is because the formatting requires a file allocation table be created and this takes up a lot of room. The data stored in this table is for addressing file segments by cylinder, track and sector. If you have a floppy disk you will notice on the diskette drawer slide it states it is a 2MB diskette but when formatted you only have 1.44MB of usable addressable space. The same is true for any formatted RW CD.

Just how much space is available after formatting a RW disc on your system depends in part on your software. It is possible to have as much as 645MB of usable space on a RW CD. Every software program is a bit different.

I hope this helps you to understand why you see this downsizing of your RW CD's usable space after formatting.

You can also bypass proprietary software and just use Windows. You paste your files to the CD drive and you'll notice a new top section in the file window pane that is titled "Files Waiting to be Written". You have to right click the right hand side of the Explorer view of your drive and then select the command, "write these files to disk". You'll probably end up with more usable space by letting Windows format it for you in this manner. However, it does depend in part on your drive's maker.

    Data written to a CD-R is written much like a phonograph record, it is in one contiguous line of data with file header information that states Start of File, End of File and the file name itself inside that header. Because it is written in this manner, without the need for a File Allocation Table you will get nearly all 700MB of space as usable. Note that you will not be able to put 700MB of data on a 700MB disc. You can try this as a little experiment is you want, you just receive another error message as to disc space.

    Another good example of this loss of storage size as advertised is in Hard Drives. A 500GB Hard Drive will not even come anywhere close to the advertised usable space once it is formatted, but when you see your drive in the System, it will be labeled and described as a 500GB drive.

    I do understand this is somewhat bewildering and we computer users, builders and owners have to accept the fact that this is the way it is and move on with the knowledge of what space there is available in spite of labels.

    Some software varies on its approach to reserving file space on a CD-RW. Some reserve more and others less. My suggestion is to use Nero if you can afford it. There are free CD Writing/Formatting software titles out there but some leave a great deal to be desired. As a shopper it is buyer beware. However, the maker of your CD-RW media will have no affect on how much file space is available or not.

    Best Regards,

Will an optical drive from cq62 fit mine?


I sort of see your reasoning, but NO.
HP Compaq DC7700 Ultra-Slim Desktop PC, and Compaq Presario CQ62 series of Notebook PC DVD burner drive?

Until I compared both units I would have stated NO.

Now that I have THANK YOU. I just learned something,

Referring back to the photo view, of the Compaq Presario CQ62 series of Notebook PC's DVD burner drive shown, the REAR view shows the connectors for the SATA power cable, and SATA data cable.

The connectors use the same L-shape design, and size that a SATA unit for a desktop computer, would use.

Case design looks to be similar also.

I believe you are Correct.

My DVD/CDW-ROM drive is gone! It is a TSSTcorp TS-H552D How can I down load a new driver free?

Try the following link;

If that doesn't work I suggest you install a free program called "Slim Drivers" and allow it to scan your system and locate the correct driver. I recommend noting which drivers you're installing so they can be rolled back should one of them not function properly.

Tsst-h652d not working after upgrade, thinks its a cdrom not combo

Well, I'm sorry it didn't work out for you. It was still worth a try. I have to agree with you. Since it isn't being recognized properly it probably isn't worth the trouble getting it repaired since typically that costs more than buying a new one. If you need to find some good prices on CD/DVD readers & burners you can look online here:


Simply navigate to Computer Hardware > CD / DVD Burners & Media. After the page loads simply click, "CD / DVD Burners" located in the menu on the left.

Let me know if I can do anything else for you (posted as a solution so you could rate the responses above).
