Here is an example of what I've been referring to as "benign" file corruption: [null @ 00000000004487c0] Application provided invalid, non monotonically increasing dts to muxer in stream 0: 18 >= 18 [null @ 00000000004487c0] Application provided invalid, non monotonically increasing dts to...

Out of curiousity: Where you running Google Chrome browser while doing so? I remember having a kinda similar problem with another program in the past. While Chrome was open, I could not make a drive lock to the external device, causing the program to fail. I still don't know, why Chrome would even ...

So, I just had this issue again on a completely new USB drive (2TB Crucial MX500 SATA SSD connected via JMicron SATA to USB3.0 controller). Use case scenario: I opened a DVD ISO file in MakeMKV (the ISO resides on the SSD) and extracted the mkv's to the same drive. i.e the source and destination dri...

It isn't clear to me what the future of optical drives are. Using optical media for long term archiving of data seems like a poor choice at this point since optical drives might've effectively disappeared in 20 years. I think of Zip drives as an example. In the 1990s they seemed to be everywhere an...

I also had this problem with the same drive which I had before. That is why I bought a new one, thinking there must be somethine else wrong with the drive. Was your previous drive a different model? Because if so, then maybe its not the drive's fault? Maybe try moving it to a different SATA port, a...

I have 3 different drives. They often produce different results… by that I mean a disc that won't rip in one of the drives will rip in a different drive. Lots of folks on this forum have similar experiences. One user occasionally mentions an ancient drive he sometimes presses into duty that has bee...

Fascinating observation, I've a DVD-ROM DL disc with 8 episodes on it where 2 of the episodes cannot be read with either LiteOn or Asus (brand new 5.25" current model drives). It always gets to a certain sector and gets unrecoverable read errors at that spot. I suspect the disc is damaged by a ...

will be doing another 100 discs so I'll report back whether that improves it Having the issue again with the LiteOn. Instead of cleaning the disc I just reposition it in the tray slightly and reload it, and it goes back to full speed. Is it possible the spindle inside the drive has some asymmetry t...

Interesting thread. I do believe long term data storage (20+ years) is a problem in need of a solution. I recently experienced file corruption on a 10 year old Seagate HDD which barely had any use, so I would have to agree that HDD is not reliable over decades. If you go to Amazon reviews and sort b...

These were all brand new discs that didn't really need cleaning, unless there is some invisible factory residue on them or something. That's more common than you think. Also, sometimes, the plastic case can off-gas and deposit 'stuff' on the disc. Yes, I think there is definitely truth to that as I...

After doing some more discs I'm finding the Asus is more reliable at hitting full speed. Had a couple discs now which the Liteon could only read at half speed. In one case a wipe with a damp tissue brought it to full speed again, but on another disc that didn't work and I had to eject the disc and r...

Did some discs with the LiteOn iHAS324. As expected the speed is the same as the Asus, and that is fine. It is definitely not using the same hardware as the Asus. The most noticeable thing is that it's quieter, so I'd pick it over the Asus if I had to choose one. In practice it's probably best to ha...

I have ordered a LiteOn iHAS324 which should be different hardware. I'm not confident it will be any faster than the 12MB/sec average of the Asus, but it's worth a shot. I'd be curious to know if the Bluray drives are any faster than 12MB/sec average, if anyone can comment on that. Just saw this......

On dual layer discs, the second layer starts at the outside of the disc and spirals towards the inner ring. Hence the read speed slows down as the laser head moves back towards the middle. D'oh, how did I not realise that :oops: While I'm here I might as well mention the speeds I've been getting on...

According to photo comparisons and anecdotes, it seems Asus DRW-24D5MT and LG GH24NSD1 may be using the same internal hardware. In that case I have ordered a LiteOn iHAS324 which should be different hardware. I'm not confident it will be any faster than the 12MB/sec average of the Asus, but it's wor...
