[comp.sys.amiga] More disk woes - Help!

carpent@coltrane.SRC.Honeywell.COM (Todd Carpenter) (05/11/89)

I have been having ST506 disk trouble.  I posted earlier on the net, and
received quite a few replies.  The net police also announced their existance,
and informed me that I sinned.  See, I was posting on the basis of rumors, and
neglected to post *real* data, such as mountlist info.  I repent of my errant
ways, and swear off rumors.  However, the beast still does not work (despite
the people offering help).  I conclude I did not give enough real information.

What I wish to do:
  I have a Rodime 5090 ST506 Hard drive I wish to install on my system.  My
SCSI is *much* faster, so I prefer to boot off it instead of the ST506.
Barring this, I will simply have a small partition on the ST506 which mounts
the SCSI and continue booting from that (much like my OFS partition on the
SCSI).  The ST506 will be used for image storage, etc.  It will be FFS. (except
for the OFS initial partition)

How things really worked:

> mount res0:               (AmigaDOS mount, not ARP)
> PREP res0:
  (answer very straightforward questions.  Mainly matching the mountlist)
  (first partition is 2->19)

  (told to reboot.  I do so)

 blue screen, requestor pops up with message:  NOT A DOS DISK IN UNIT 1

  (so I turn it off, reboot again, once running, turn it back on, let it spin
   up for some time.)

> mount res0:
> format drive res0: name "BH0"

 INSERT DISK...
  formatting cylinder 0, 1 to go
  done

> info dh0:
 DH0:  No disk present

 (if I do anything to res0: I get the NOT A DOS DISK IN UNIT 1)


My (unenlightened) feeling is that the trouble is during the PREP.  Why?
Sometimes Prep doesn't work.  And I don't think I should get the "NOT A DOS
DISK" when I reboot, after the prep, before the format.

I also had a large first partition, which *seemed* to format (lights blinked,
the servo moved), but I received the same requestor in the end.

Part of my earlier trouble (I'm ashamed to say) was Reserved = 0, and FFS
initial partition.  (I thought since my SCSI had an OFS, I could get away with
it).  I fixed that, but to no avail.

My system:

ST-506: Ro5090    (the errant beast)
 7 heads
 1218 cylinders
 17 sectors/track
 5 MHz xfer
 90MB

SCSI: (rodime)   (works great)
B2000             ditto
A2090a            ?? fine with SCSI
A2620            (functions wonderfully - buy one for you friends, too!)
AmigaDOS1.3
1.3 ROMs
ARP1.3 (w/o mount)



Mountlist for ST-506:

/* ST-506 hard disk drives are units 1 and 2 */
RES0:      Device = hddisk.device
           Unit   = 1
           Flags  = 0
           Surfaces  = 7
           BlocksPerTrack = 17
           Reserved = 2
           Interleave = 0
           LowCyl = 0  ;  HighCyl = 1
           Buffers = 20
           BufMemType = 0
#

/* Sample Mountlist Entry to add another partition to a ST-506 drive */
FH0:       Device = hddisk.device
           Unit   = 1
           Flags  = 0
           Surfaces  = 7
           BlocksPerTrack = 17
           Reserved = 2
           Interleave = 0
           LowCyl = 20  ;  HighCyl = 1217
           Buffers = 20
	   BufMemType = 0
           FileSystem = l:FastFileSystem
           DosType = 0x444F5301
           GlobVec = -1

email replies seem to get to me:

Note: Now that the net police have made themselves known, and bashed me for
listening to and being concerned about rumors, I know I have sinned, and will
try to change.  However, I still refuse to believe in the mythical line ea

so far so good.  You have wiped the data from dh0:

NO NO NO
THIS ERASES THE INFORMATION STORED ON THE FIRST TWO RESERVED CYLINDERS!!!

instead just 

format drive dh0: name FunnyPart


Don't remount res0:
Don't ever format res0:

The manual has a few words on this as well.

Thanks for your reply!  I still can't get it to work...

But, but, but:  page 25, item (2) says to always mount before prepping.
But (the main thingie), um (blush), yes, I should be formatting dh0:  I feel so
foolish.  It still doesn't work:

1) I did what you said (right after boot) .  It responded with "Drive not
found"
2) I mounted DH0: and got "Device "dh0:" not recognized"
3) I mounted RES0:, tried the above format command:  "Drive not found"

Anything else?  I'm willing to try almost anything legal.

Ok, lets try again.

RES0: is for PREPing the first ST506 drive
RES2: is for PREPing the first SCSI drive.

The sequence is


mount res0:
prep res0:

(answer the questions properly; if you enter incorrect information
 the drive may not be found)

REBOOT THE MACHINE

Now, drive dh0: should be automounted.

do an 
assign

and an info

and see what drives you see in the lists.  you should see
a DH0:

Now format dh0:

That's pretty much it.
