So far, so good ...

Don't know the Toshiba, but I have a Seagate that behaves in
a similar way: Sometimes it won't accept two large chunks of
data (say, 256 sectors each) in a row. I assume there must
be a bug somewhere in the drive's firmware.

I knew someone might find this useful one day ... :-)

That's more than 128K just for buffers! Do you really want
to waste that much RAM? The RAM-disk would probably be
faster then! You could still use AddBuffers in your
startup-sequence, though.

This switch doesn't have any meaning for the AT interface.
Ignore it!

Don't worry! If it works, I'd assume it's correct.

Normally, the driver will split all I/O-requests larger than
128K (256 sectors w/ 512 bytes each, the maximum an AT drive
can handle) into separate AT-requests, so it shouldn't be a
problem. I assume something is wrong with the drive.

Hello,
last month i bought an 105 MB Toshiba AT-Bus HD for my GVP 3001, which is
equal to the 105 MB Conner AT-Bus HD. I realized, that the Software on the
GVP-Installation Disk was too old, it makes problems with the Modem. So i
ordered the Autoboot-Kit and continued using my 2090 until the Kit will
arrive. There were some mystireous Failures with the old Software, the
Speed-Test of THI-Tools fails at 128 KB read/write and the Speed-Test of
Alf failed too, the Harddisk hang and i had to reboot. Now i have the Kit
Version 2.3 and a second HD, a 211 MB Rodime. The software works great with
Rodime and has no problem with the modem anymore. But the 
Toshiba still refuses to work with big files. Besides the Faaast-Prep-Prog.
i found the gvpprepat in the gvputils-dir. This software allows to set the
maxtransfer. I tested some values and found that 100000 is to high and 70000
works. The only Problem is, that this prep-software limits the Buffers to 256
and you cannot set the synchronous/asynchronous transfer. So if i use 
faaast-prep after using gvpprepat i can change these things, but it overwrites
the maxtransfer-value and sets it to the normal value (maxint).

The questions are, how do i have to set the Jumpers of the Toshiba to work
correctly as a slave to the Rodime, i found a setting that both drives work
correctly together, but i don't know if its correct ? 
Is it normal that i have to set the Maxtransfer for the Toshiba (Conner) or is
the drive broken ?
How can i set Maxtransfer from faaast-prep or how can i force him to use the
preveous value ?

Please help if you can, i want to use the Toshiba as boot-hd, but i can not
trust it.

Bye, Helmut.
