KyroFlux - How might it compare to the CatWeasel?
Link: http://webstore.kryoflux.com/catalog...products_id=41
I'm not sure what "precisely sampling the magnetic flux transition timing" means, but if it means it reads my problematic floppies faster than one per days, that sounds good to me. Your thoughts? |
You are not able to write images using kryoflux so if you want to actually write your disk images do not buy the Kryoflux
|
Kryoflux software that includes write support is due for imminent release though, no...?
http://forum.kryoflux.com/viewtopic.php?f=2&t=39 As someone who has owned a Catweasel Mk.IV and also owns a Kryoflux I can say that reading of disk images is *far* better with the Kryoflux, in my opinion anyway. Once write support has been added, I can personally see no reason why anyone should prefer the Catweasel. |
No, if you read all the posts, they have not had time to implement write support and it is not forthcoming soon. it keeps getting pushed back

The posts do read to me like delays have been introduced by wanting any write support update to be a perfectly working solution rather than a potentially bugged release.
I'll stay hopeful there will soon be write support available with Kryoflux. :) |
its forthcoming just as soon as its finished.
it not being pushed back at all, its being worked on constantly, between our day jobs, and all other kryoflux/SPS stuff is being held back while its being finished off. sure its frustrating for those that are waiting that its not ready yet. we dont expect anyone to really understand the reasons why this takes so much time and has to be correct, but we do appreciate your patience while we deliver it so! |
And I am pretty sure we never hid that fact... we always said preservation comes first and writing is a bonus. It's coming, and we're making it rock solid. Not "could work", "should work", "is supposed to work".
In regard to quality, we are not going to comment on competitive products. There are reasons we made our own, and there are reasons why large institutes like the British Library have chosen KryoFlux over competitive products. http://www.wired.co.uk/news/archive/...gital-archives I would recommend looking at formats supported (what kind of disks can be read), operating systems supported (Windows 64bit? Mac OS? Linux?), portability (e.g. is it plug & play via USB) and expertise of people involved (SPS). Cheers! |
I am convinced enough to have ordered one. :)
(...and I already own an ISA Catweasel, and Catweasels III and IV. ;)) |

The input you can give, however, is informative on the Kyroflux - Thanks. Quote:
I do have a few questions for those who've bought one, though. Feel free to answer any or none. 1) What's the CPU usage like on your computer (please include make and model of your CPU)? 2) About how long does it take to read a good Amiga floppy? A damaged one? A very damaged one? 3) How much (or little) heat and noise is produced? 4) Can you pause/resume a disk read? After closing the program (I'm assuming the Kyroflux comes with a software program that runs the hardware)? After a computer power off and on? |
1) Not really measurable, below one percent (i7-2600K)
2) A good one takes about 3-4 minutes 3) It's just what the floppy drive produces normally 4) Doesn't seem like it, haven't looked in-depth though |
1) about 1-2% on 1.6GHz Atom CPU
2) ADOS to ADF: 2 min. 10 sec. (full error correction on*); forensic dump for preservation 3 min. 42 sec. 3) indeed, normal drive noise only. 4) Sector dumps, like ADF, are one pass (no pause, no continue). Forensic dumps create one file per cylinder / side, so you can always replace tracks dumped lateron by setting start end end track for dumping. *KryoFlux comes with advanced algorithms that can very precisely decode bitcells from flux reversals. Even slightly malformed or misaligned data can usually be read. For C64 dumps the error correction is even more precise than on the C64 itself, which means KryoFlux can detect errors in decoding that would go undetected on a C64. More advanced analysis can be done with our Analyser which can even recreate broken protection tracks like Rob Northen Copylock. Please note that the latter is not part of the KryoFlux package, but both share some ideas and techniques. |
