Stuck w/ "Synchronizoing Cache..."


Recommended Posts


First time this happened.

I wasted already three BR 50 GB on this. No clue why this happens. I have 50.045.xxx.xxx bytes of data to be written. All goes fine until the very end where ImgBurn is stuck w/ the message "Synchronizing Cache..." (in Log). No error messages, also not in Log.

Any ideas why?

Please post the log of the entire burn session.

Sync cache is a command send to the drive once all the data has been transferred to it. The drive then goes off and completes the burn. For whatever reason, your drive appears to be having a problem doing that - maybe because it's right at the edge of the disc?

Just to make it clear. If the disc reports a capacity to ImgBurn, and ImgBurn knows how much data to write, does this mean that all data (including structures, overhead, ...) fit the disc and will be written successfully?

In other words, could it be that the 50.045.xxx.xxx Bytes were too much for the disc and ImgBurn would not complain prioir write, but the drive would eventually just fail to write (like in my case)?

If ImgBurn doesn't tell you that it won't fit, it'll fit.

There's just more chance of the drive failing to burn / close the disc on the outer edge.

It still shouldn't get stuck forever though. Can you hear the drive doing anything? Does it keep spinning forever?

When you eventually force it to end (by powering off the machine or whatever), can you then restart the machine and is the drive able to initialise the disc ok? What comes up in the disc info box on the right when you fire up ImgBurn and go into Write mode?

Yes, the drive went stuck forever. I can't recall if it was still spinning or not. I had to stop ImgBurn via Task Manager (End Task). Even after that, the drive was flashing and I could not eject the disc. I had to restart the system.

After restart of the system, I checked the disc and it looked like all data was on. Since all data had md5 checksums, I ran them. All data was correct!

Nevertheless I didn't "trust" this disc, reduced the volume from 50.045... to 50.043... and this time the write operation succeeded!
