Catweasel (MK3) floppy controller question..

I figure this might be a decent place to ask.. Does anyone know of a program I can use (preferably under Linux, but DOS would probably work as well) to read a flux-transition level image off a disk using a catweasel card? I'm trying to read some 2.4MB (5.25") floppies from an IBM 3174 controller (using an 2.4MB floppy drive), and am able to read in 1.2MB floppies using cw2dmk just fine, but it doesn't do so well at processing the (aparently) mixed-density floppy I've been screwing with since yesterday. Using the "testhist" program included with cw2dmk, I can get information about the "unreadable" tracks, but cw2dmk won't process them. I'm trying to make a backup image of a disk so that I'm not screwed when the disk stops being readable... For those interested, it appears that "2.4MB" floppy drives are 96 TPI just like 5.25" DS/HD drives, but they support a higher bit rate. Here's what testhist tells me for a "normal" HD track: mii-300:/usr/src/cw2dmk-3.4# ./testhist 0 0 0 1 2 Reading track 0, side 1... 0: 000000 000000 000000 000000 000000 000000 000000 000000 8: 000000 000000 000000 000000 000000 000000 000003 000001 16: 000008 000005 000002 000005 000012 000006 000010 000479 24: 003590 012073 083091 150788 000112 000013 000004 000004 <snip> peak 0: mean 26.52101, sd 0.67534 peak 1: mean 41.56100, sd 1.04145 peak 2: mean 55.25931, sd 0.90741 drive speed approx 360.943152 RPM MFM data clock approx 510.486128 kHz And for a higher density "2.4MB" track: mii-300:/usr/src/cw2dmk-3.4# ./testhist 0 0 1 1 2 Reading track 1, side 1... 0: 000000 000000 000000 000000 000000 000000 000000 000000 8: 000000 000000 000000 000000 000000 000000 000324 000605 16: 000579 000472 006881 107754 120911 001047 000736 000639 24: 000743 000819 000079 000019 000003 000005 000000 000006 <snip> peak 0: mean 19.51057, sd 0.82054 peak 1: mean 33.65562, sd 1.27275 peak 2: mean 48.29739, sd 0.48487 drive speed approx 374.227723 RPM MFM data clock approx 653.668108 kHz I don't care so much about being able to interpret the data that's there as much as just being able to make a duplicate of the disk which is acceptable to the 3174 controller when this disk bites the dust.
