Hello, I just recently purchased a Plextor PX-608CU and since it’s my first drive capable of writing to DVD-RAM’s, I thought I would pick up a 5-pack to check them out. I got some Panasonic 2-3x DVD-RAM’s (my burner supports up to 5x), and (full) formatted them as FAT32 under Windows (after disabling Windows CD Recording on the drive). I do not have any DLA/InCD software installed, FYI.
Anyway, I copied a few small files and it worked just fine. I was pretty happy. However, then I wondered what would happen if I ran a chkdsk /r on one of these discs. I ended up with about 275+MB of bad sectors. I thought it might be a fluke, or that I wasn’t supposed to use chkdsk on the discs, so I reformatted the disc, and tried copying a large RAR file to the disc. Eventually I had a few write delay errors and it gave up. I decided to run chkdsk /r on the remaining 4 discs after (full) formatting them. Every disc had a couple hundred megabytes of bad spots.
My question is… is this normal behavior for DVD-RAM’s, or what? If so, I can tell why they don’t seem to be very popular anymore.
Here’s what chkdsk logged:
C:\>chkdsk /r /v G: The type of the file system is FAT32.

Cannot write boot sector.
I’m also not sure what’s up with this: “Bad sectors found.ted .” Is that a typo, or what?
Any ideas? Thanks!
