Acer notebook DVDRW suddenly not working

I have an Acer Aspire series 1680 notebook with an internal Slimtype DVDRW SOSW-852S. I was using the drive without any problems for nine months. One day, I was watching VCD in it and then it suddenly wouldn't work in the middle of the video. After that, it won't read nor write any kind of CD anymore. The Windows OS can still see it and shows it as without any problems. I tried using a bootable CD in it to check if it is the Windows driver but the CD won't boot either. So it looks like a hardware problem. I disabled the Windows hardware profile of the DVDRW drive. After several days, I enabled it again and tried reading a DVD video on it. It suddenly worked and set the region settings to the DVDCD's region (region 3). Before, it never does this but this time, it automatically set its region setting to the DVD's region. When I tried reading other DVD videos from the same region, some worked, some didn't. I tried reading DVD softwares, it can't read it. I tried reading VCDs and software CDs but it can't read it either. It could just read some DVDs from region 3. So what's the problem here? Initially it seems its a hardware problem. Then after sometime of being disabled then enabled, it seems to be a software problem. Please help! Getting it fixed from the service center is too expensive for me.

My DVDRW works again, I think the latest update of windows 7 has taken care of the problem, but I'm not sure.

Burn discs

Or you talking about burning DVD or CD.

Do do a Google search on XP Burner this is a good software for FREE software for burner CD. For DVD, go to and get a free version of their software and see if you like it for 30 days.

Slimtype dvdrw SOSW-852s jumpy when playing CDs. Shows CD with photographs ok.

Hi - I would suggest that buy a cleaner for the drive, and try playing you cd's afterwords. If it still playing up then copy some music from the computer onto a brand new cd and play back. If that still has the same fault then you may need to but a new drive.

I hope that helps you.

Please let me know how you get on.




it's look like windows registry problem.
follow this step from microsoft:

if this isnot working, try to reload your operating system.


Sorry I can't offer any help, but then again, even Liteon couldn't help and posted a notice on their website a while back stating that these units were subject to drive failure.

" DVD-RW Drive SOSW-852S
NOTE: This is a system integrator product. Due to compatibility concerns, which may cause drive failure, we are not able to provide any firmware upgrade for this product. For technical support, kindly contact your vendor."

sounds like you're suffering the jungle DVD fever disease, most likely from excess salt air exposure(same thing happens over here on Hawaiian islands). So, just swap out the DVD for another one, and mark your calendar for same drill in another year.

got backup for your computer?

My recommendation is to get the exact replacement that Acer recommend. OR a third party equivalent.

In saying that as long as one has a warranty for said device, then really anything else is a moot point.

I think you will find that the Panasonic drive will be more than suitable.
