Thank you for visiting.
I cut back on my Upgrade project due to
lack of funds. My main priority was to
replace the 850Mb drive which was causing
most of my crashes, and corrupting data.
Inspection revealed a puncture in the silver
tape seal on one side of the drive cavity.
I took the opportunity to upgrade to windows
95, so an extra 16mb Simm was also purchased.
I had backed up stuff to my original 220mb
drive. My new drive was a WD 5.1 Gigabyte
model, at the same price as a WD 3.1 GB
EIDE model. Since I used an older 486
with the on-board controller I needed
the EZ drive software to support this large
of a hard drive. Eventually I got the
new hard drive up and running with
windows 95 loaded.
Now the problem.
My device manager showed a yellow warning
for the ESDI controller and drives.
This was revealed by the performance TAB
as MS-DOS compatability Mode Paging on
all the drive letters, meaning I could not
enable the 32bit transfer mode.
In the Windows Topic help
This is attributed to Win95 not being able
to replace an original driver in config.sys
with a Windows 95 version driver, but
there wasn't anything in the config
to cause this, as everything had been
remarked out prior. Checking the Hard
drive manual again, it appeared I was
going to have to reformat and use FDisk
to enable 32bit transfers. I cleaned up
the 220Mb slave drive to prepare for
backing it up. Then I decided to see
if I could fix my problem by using EZ
drive on the 220mb drive since it was
also a Caviar model. Enabling EZ drive
for this model didn't fix the compatability
mode paging, but it did fudge the boot up
information so all the information I had
backed up to it was replaced by an
earlier incarnation of data on the drive,
including a failed LINUX installation.
It was as if I had performed an Unformat
operation. I tried different things to
get all my backed up data back. Finally,
pissed off at the whole thing,
I set the CMOS settings for the Second
drive to NONE. Upon rebooting Win95 my MS-DOS
Compatibility mode problem went away...
The lesson is that the Windows95 IOS setup will
put a turnequet on your neck to stop
a cut on your chin from bleeding. In this
case the Chin was the old hardrive incapable
of current LBA Translating schemes, and the
Neck is the hard drive controller that
has to deal with both the primary master
and the primary slave drives.
