[Coco] Looking for "C" utils

[Bill Pierce]

They are not SCSI drives. They're MFM drives. And the sound is internal to the drive itself.. with or without a controller connected. It comes from the head going back to zero after spinnup. I have thought of pulling the controller rom and cleaning the pins though. The "Error 47" is from OS9... I don't think it's generated by the controller. Just the driver saying the drive isn't ready to be read.

Hi,
>From a Seagate product manual for an earlier drive: (Lower Numbers)
It talks about flashes, not sounds. The SCSI interface manual has
orresponding error codes up to a point.
NO flashes or peeps means NO Errors!
1 flash = Microprocessor / Internal Memory Test failure.
2 flashes = Microprocessor Checksum Test failure.
3 flashes = Controller Chip Test failure.
4 flashes = Controller Program RAM failure.
5 flashes = Data buffer RAM test failure.
6 flashes = Spindle Speed Test failure.
The SCSI manual Sense Keys says 47 = SCSI interface parity error.
Time to throw in the towel?

 Yep, Mike said he had to bang on these ocassionally to get them to spin... 
 they're spinning up... just not to speed. Motors whir, heads chatter.. 
 then h0 goes peep peep.... h1 goes peep, peep, peep, peep. I assume 2 
 peeps means ok, drive reads. the 4 peeps give error 47 from then on.
 As I said before... I can read h0 for about 30-40 minutes before it starts 
 giving error 47. The files are there, just no way to get them to the PC. I 
 have them saved to a 3.5" floppy. My regular PC has no floppy drive or 
 connections for one. I have another that I'm working on getting it to read 
 coco disks but no luck yet. My wife and I are on fixed income and have a 
 tight buget so I have to wait a bit before I can order the cable for 
 drivewire. I also have to get a USB to serial adapter as my PC has no 
 DB-9. It will all come together soon.
 I really appreciate the help Stephen, Mind if I pick your brain from time 
 to time on C code? I always worked in Asm or Basic09, I messed with C for 
 about a month with OS9 Level 1 then Level 2 came out and I like basic09 
 being so much faster under lv2 and RMA was awsome. I just never got back 
 to C.

 Thanks Again!
