I had purchased IC 6.2 back in September and used it to successfully bake an HDVR2. No Problems.

I attempted to use the same disk to bake an SD-DVR40 image and during the mftstool restore I get a message (from memory) "4 of 1449 MB Restored (Compression XXXXX)". The restore never finishes as the restoration never gets beyond 4 MB (sometimes 12) and XXXXX is a unreadable rapidly changing number with absurd values such as "Compression 8617%".

I thought my CD may be corrupt so I purchased another, burned the ISO, and received the same error. I tried both a 320MB and and 250MB Western Digital drive with the drive identified as /dev/hdc (Secondary Master) and the CD-ROM as /dev/hdb (Primary Slave) per instructions.

The only difference in my computer configuration since the last time I baked an image is the addition of a new Sony 810U DVD-R.

Any help would be appreciated.

Thanks,
Scott

when folks have this problem its usually a result of CD media problem (do a search on "compression" and you'll see...); you might try either a different media type and/or a slower burning speed, that usually clears up the problem.

Thanks for your reply. It's possible it's a media problem so I'm going to try and burn a different brand of CD at a lower speed.

I suspect it's not a media problem though because, as I stated in my earlier email, I was able to successfully bake my HDVR2 with the same disk that gave me problems on my SDDVR. I do suspect my CD-R burner since it's the only part that's changed since baking my HDVR2? Has there been any known problems with CD players while restoring an image? Perhaps MFStools is trying to use an unsupported PIO/DMA mode?

Also, can you provide me with the MD5 checksum for the most recent version of IC 6.2 for SD-DVR40 so I can verify my ISO file is correct?

Thanks in advance,
Scott

This is frustrating. I did a search on "compression" and it appears many people are having the same "exact" problem and the recurring theme isn't ISO corruption, it is hardware.

I also reviewed the release notes. If I could make a suggestion it would be helpful if the release notes contained a "Known Problems" section. After hours of downloading, burning and baking my problem is, indeed, my DVD burner. A first candidate for your release notes incompatibility list is the the well known "compression" problem and the Sony DRU-810A.

thanks for the thoughts. please keep in mind that is a very rare problem, and i don't think there is enough data to suggest that its specific to the DRU-810A, it could be a combination of that and something else in your environment.

this forum, and especially the official support thread are ideal for discussion of problems such as yours - hopefully the next person who searches will find it before creating a new thread.
