Subject: Re: I need a ST-419 hard drive
Originally to: jeff.kaneko(a)juno.com
Jeff,
I tried a ST-251-1 but it wouldn't work. Here's the story:
I picked up a HP 9133XV drive with a bad drive in it. The XV is the one
that you can partion into 4 so that it looks like 4 HP 9895 floppy drives
to the system. It's the only hard drive that can be used on the HP 85, 150
and some of the others. This one has a Seagate ST-419 drive in. I
replaced it with a Seagate ST-251 that has the same number of heads but
more tracks and is smaller and faster. The system recognizes if but it
won't format it. It says that the drives are bad. I'd like to get it
running again since the XV drives are hard to find.
The 251 does have fewer sectors (17 vs 32). I don't know if that's why
it failed or not.
Joe
That exactly why this failed. The platters themselves can't handle
that much sectors.
Try:
Find 2 HD's:
ST296N (electronics can be dead but must have good pack)
ST277R (the pack can be bad, but needs the electronics.)
Use the ST277R board on the ST296N pack to give you
compatiablity for the HP85.
There are many other drives that has 32 sectors or up but with
"different interface" but another hd that use HDA to logicboard
interface that shares same design and take the RLL rated logic
board to another drive that does this 32 or up sectors.
