In Reply to: HP c2490a J pin city? Got a Clue? posted by Chris on September 06, 19100 at 16:58:06:
: Hello Compadres;
: I picked up a beautifull old HP hard drive that has 16 J pin rows. I can get it to start up by syncing the spindel to power start up....But? Found the J pin schematic on HP's site. Don't really understand it all though. Using HDT primer software or the Apple 8.5 Drive setup, the drive is never ready when the scsi bus is scanned. Cant seem to wake it up for formatting. This drive is a couple of gig so It's worthwhile. Anyone with any J pin description analysis experience please E-mail me at Codestar7@aol.com.....Thanks guys.
: P.S. Could really use some cheap SCA to SCSI adapters too.
hello chris
i saw your problem description on http://www.thetechpage.com/cgi-bin/default.cgi?/forum/messages/10164
i have the same hot and loud hp disk c2490a and it runs fine whit my old mac (os 7.6.1) and with little problems via an usb-scsi adapter from microtech on my new iMac (os 9.0.4).
on my old system i had to patch the "apple hd sc setup" whit a patch found here http://www.thetechpage.com/cgi-bin/default.cgi?/utilities/patch732/applehdscsetup7_32patch_sit.hqx
my jumper settings are:
J1 to J3 (look at the hp-site for your right scsi-id, usually not 0
and not 7, reserved by cpu and internal drive)
J7,J9 and J10 are shortened
rest are open.
hope this helps
