[Coco] CocoDisk was: nitros-9

[Bob Devries]

Darren,

I have tried your CocoDisk.
The following observations are from my brief experience:

The programme quits without saving anything when it detects any sort of read 
error. With many of my disks being aged, I would love to see the programme 
skipping over problem sectors, and storing a known pattern in the bad 
sector. For preference, the fill byte for a bad sector should be user 
selectable; that way, it can be made, say, $E5 for RSDOS, and $FF for OS9 
(yeah, I know, that is the reverse of what is used for blank sectors... 
That's the idea!)

I also was not able to get it to write a (MESS) image onto the disk without 
error. It may have been a bad disk; I'll need to experiment some more. BTW, 
at this time, I'm using 3.5" disks, as that is all I have in this Windoze 
box. The error given was that your programme could not find the required 
sector.

Hope that helps.

>>
>>It doesn't require registration like OmniFlop.  You will need to download

>>So far, I've gotten no reports of anyone having actually used this

>>The main restriction with the current version is that it doesn't support

>>I hope to remedy this problem soon.

>>Cheers,
>>Darren
