Format BD-RE 50GB fails at 99%

[jmone]

ImgBurn is reporting a format failure at 99% when doing the initial full format on BD-RE 50 GB Discs, but subseqent "Quick Format" seems to work fine (see logs). This has happened on the first two of my TDKBLD-Wfa-00 disks (now testing the third). These discs now seem to be writable but:

1) are they safe to use?

2) are there other ImgBurn setting I should have used?

3) other hints?

 

Thanks

Nathan

Burn one in Discovery mode and just check it writes+verifies everything ok.

 

If it does, assume it's safe to use.

 

The LG drives do seem to fail on media that's not Verbatim stuff quite often. It's a shame they don't make 50GB discs yet.

 

Panasonic do a 50GB one though, maybe the drive will like that dye a little more.

Thanks - will try and post back the details (but given the 3hrs just for the first format it will be awhile!)

Thankfully you only have to format it just once: after that you can simply overwrite the data

FYI - the final of the three Discs (TDKBLD-Wfa-00) formatted correctly. I've also now checked one of the "failed at 99%" discs by Burning in Discovery mode / verify and everything was ok.

Thanks
