Hi,
I am having a reproducible issue with the new Avatar: Fire and Ash UHD.
Drive Information:
ASUS BW-16D1HT
Firmware 3.10
LibreDrive enabled
Firmware type: Patched (microcode access re-enabled)
Disc Information:
Avatar: Fire and Ash UHD
Retail disc, purchased new
Label: AVATAR_FIRE_AND_ASH
UHD BD-ROM (triple layer)
AACS2.0/C v82
The disc opens normally in MakeMKV. All playlists are scanned successfully and the main feature is detected correctly.
However, both MKV extraction and a full Backup with "Decrypt video files" enabled fail at exactly the same location every time:
Scsi error - ILLEGAL REQUEST: INVALID FIELD IN CDB
while reading:
/BDMV/STREAM/00294.m2ts
at offset:
2913730560
I have tested the following:
Multiple attempts
Retry Count increased from 10 to 50
Disc cleaned thoroughly with water and mild detergent
Full Backup with decrypt enabled
Standard MKV extraction
All tests fail at exactly the same file and offset.
Additional observations:
Other UHD discs rip successfully on the same drive.
LibreDrive appears to be functioning normally.
The disc structure is read correctly.
The main feature is detected correctly.
A Panasonic UB820 standalone player appears to play the disc normally, although I have not yet watched the entire movie.
What makes me question whether this is a simple bad-disc issue is that the error is consistently:
ILLEGAL REQUEST: INVALID FIELD IN CDB
rather than the more typical MEDIUM ERROR / UNRECOVERED READ ERROR.
After the initial failure, MakeMKV repeatedly retries the read operation and generates many instances of:
OS error - The specified request is not a valid operation for the target device
always at the same offset.
Has anyone else seen this with Avatar: Fire and Ash UHD?
Does this look like:
a defective disc,
a known issue with this UHD release,
or a compatibility issue between this title and certain UHD drives such as the BW-16D1HT?
Any feedback would be appreciated.
Thanks.
