Re: New KryoFlux not recognised by multiple systems

Re: Alley Cat Booter problems

It's not reliable because you write it with a 96tpi head (80 track drive) and read it with a 48tpi head (40 Track drive). The narrow writing head leaves fragments of old writings (because it double steps and leaves all the odd tracks untouched) and does not erase the whole track width of 48tpi. The ...

Re: New KryoFlux not recognised by multiple systems

Okay, if you just plug it in (without starting DTC) it should come up as "Atmel Corp. at91sam SAMBA bootloader" (with lsusb on your linux system). Maybe you missed that, because there is no name "Kryflux" involved at this stage. If you start DTC the first time the firmware file gets loaded to the bo...

Re: Need advice on how to recover 5.25" floppy

Just a quick shot: Could be a 80 track disk reading with a 40 track drive! As there are shades of a 15 sectors per track format maybe a 1,2Mbyte DOS Disk?

Re: Need advice on how to recover 5.25" floppy

Image format is almost the same as d64! Both is basically a sector-for-sector copy of a disk... 683 sectors of 256 byte resulting in 174848 byte which is the length of a d64 file. 2880 sectors of 512 byte resulting in 1474 560 byte which is the lengt of a standard img file (1,44 MBdisk) There are no...

Re: Need advice on how to recover 5.25" floppy

Whow, I just learned something new again! I always used the track distance parameter -k to read mfm 40 track dd disks. But I never recognized that this feature is not available for the gcr coded formats! I understand that the decision was made to avoid problems with fat/half-tracks etc... But wouldn...

Re: Need advice on how to recover 5.25" floppy

Beside the 40/80 track issue the disk is very noisy from the start off but gets even more worse towards the inner tracks! That corresponds with the fact that the inner tracks are written with lower speed on a c1541 resulting in shorter fluxchanges when reading with todays drives using constant speed...

Re: Need advice on how to recover 5.25" floppy

You have to adjust the "Track Distance" switch in the image profil settings. You are using a 40 track device but the kryflux is double stepping the tracks as if it is conected to a 80 track drive. That's why the orange T boxes apear indicating that the track number is not corresponding to what's exp...
