[comp.sys.apple] Recognition of HD by S 5.0 / Formating with 3.5 drive

MAR21AA@TECHNION.BITNET (Uri Srebro) (10/25/89)

     System 5.0 still refuses to recognize my hard disk. It does check it's pre
sence when booting and when loading the finder, but it's icon isn't displayed,
nor can I access it from GS/OS aplicaitions (I can from P8 aplicaitions). It wa
s sugested to me that the directory structure is damaged in some way. This seem
s reasnable, but how do I check/fix it ? Mr. Fixit reports "no errors" and as f
ar as I checked with a block editor, nothing seems wrong. What are the bytes in
 the directory header that are marked "reserved" in the ProDOS 16 manual now us
ed for (I noticed it is used now) ?
     Another unrelated question: My Apple 3.5 drive fails to format anymore. Th
e finder, as well as Copy II+, says "format failed". I checked the drive on oth
er GSs as well as Macs and allways get "format failed". The local dealer said I
 have to replace the 3.5 motherboard (an 80$ replacement), can there be any oth
er posible reason ?
          Thanks in addvance

  If you can't recognize your SCSI drive under System 5.0 but can
under Prodos 8, you undoubtedly either failed to install the SCSI
driver or else disabled it. (Most likely the former.)

      The driver was probably insatled corectly, since GSOS does check the HD o
n bootup (at the thermometer screen) and so does the finder (after displaying t
he 3.5 disk icon).
