Does anyone on this vast earth know the jumper settings for a MiniScribe
3438 hard drive???
I've searched EVERYWHERE, and found the following:
- It is either MFM or RLL
- It is either 32 or 22 MB
- It is either 5.25 HH or 3.5" FH.
Of the sites I've found, one says that it's RLL, another says it's MFM.
Another site says it's both. Between the sites, one said it was 22 MB, the
other two said 32. One of the sites said that it was a 5.25" HH drive, and
the last said that it was a FH 3.5" (is there even such a thing?).
Other than the fact that it's 5.25" HH, I know NOTHING (useful) about this
drive. The jumper settings seem to have vanished, along with the physical
drive specs.
Help!....

Jason, the only thing I can find off hand states that the 3438 was a) a
32.7mg drive. 615 cyls, 4 heads, 26 sectors, b)that it is a 32mg ST-506
RLL and that it was 612 cyls(!!!). The former was from Mueller's
"Upgrading and Repairing PC's" and the latter was from Minasi's "PC
Upgrade
and Maintenance Guide".
Nothing on jumper settings. Do you have a date on the drive? That might
help me dig through my pile O' stuff.
