Double verifying (and slow verifying)

Although the only problem I’ve ever had burning to Verbatim discs
is that DVDFab sometimes fails to finalize DL discs properly, I do
rather like the idea of verifying that the data as read from the
disc is exactly the same as in the temporary (or other) files
ripped to my hard disk. Then too, verifying does catch the problem
when the disc is left unfinalized.

However, in clone mode, if I clone original DVD disc to blank DVD
disc (same drive or one drive to the other), then both task 3/4
and task 4/4 are verifying the disc. Okay, I can cancel out after
the first verify task is successful, but that leaves the temporary
files on my hard disc, so I have to remember to delete them.

Or I can clone to a set of ISO file on my hard disc, then use
write data to burn to a blank DVD disc, in which case task 2/3 is
burning and task 3/3 is verifying. (If task 1/3 ever happens, it’s
been too fast for me to notice.) This way, verifying is done only
once, but I have to remember to delete the ISO files from my hard
disk.

Other than that, verifying is surprisingly slow; for me, verifying
(even just once) typically takes longer than ripping and burning
combined, and I’m conservative with the burning speeds; 4X for DL,
and 8X for SL.

This seems to be the case with all versions of DVDFab Platinum
since the verify option became available.

I like the idea of verifying, but as currently implemented, it
seems rather more more time-consuming than it’s worth.

Still the same with 4.0.1.2.

Still the same with DVDFab Platinum version 4.0.3.0.

Still the same in DVDFab Platinum 4.0.5.0.

Regarding the slow verifying, verifying is noticeably faster with my newer Pioneer DVR-112D than with my older Optiarc AD-7170A, but still slower than the “copy” (ripping) task (sometimes a little, but sometimes a lot) or a transfer rate test.

In general, the Pioneer reads faster, and in particular, can often read at maximum speed “problem” areas that the Optiarc has to drop it’s rotational rate to read. I expect that it will be able to read (albeit probably at reduced speed) a disc that would result in a read error with the Optiarc.

The pioneer is cross-flashed to DVR-112, with FW 1.24 modified with MSCE to RPC1, auto bit-setting for SL +R and +RW (as well as DL +R) media, and RipLock disabled.

The Optiarc has Liggy and Dee’s firmware 1M1, RPC1 and bit-setting enabled (this drive never had RipLock, even with stock firmware).

I have also noticed very slow verify times. It’s a shame, since I find I get a coaster about 1 in 10-15 copies, and this would help avoid the issue.

Still the same with DVDFab Platinum version 4.0.5.5.

Still the same with DVDFab Platinum version 4.1.0.2.

Still the same with DVDFab Platinum version 4.1.2.0.

So, burn with imgburn instead - that is now supported in fab & has a fast verify feature.

I do prefer ImgBurn for some things, but, unlike the VSO burn engine, it won’t use the .ini file that DVDFab uses for it’s image file sets, so for clone mode (which is what I usually use), I use VSO.

In any case, it seems to me that the verify feature should work correctly with the included VSO burn engine, without resorting to any work-around.
