Is it truly a problem, or just a cosmetic issue ?

Is it truly a problem, or just a cosmetic issue ?

if i install win98 the resul is a 4gb c: hard drive

Which bios version is on the scsi controller ?

edit: check here [SOLVED] Need some help locating a specific BIOS for an Adaptec AHA-2940U2 OEM SCSI card.

i will try tnks. and.. the scsi settings (on the card and on the drive) are all correct? tnks

looks default, default settings should be fine.

On your picture of the drive.
As you are looking at it you have a jumper on pins 6 and 5.

Can you move the jumper block (or add another one) to jumper pins 4 as well or instead of 5.

So if you dont have a spare block then dont force SE mode, set the ID to 0 instead.

Agreed on the force se jumper not needed,
the term power jumper is also not needed
but
setting the jumper on ID BIT 0 would make the drive be ID 1

I dont know if it is or isnt required because I dont know the cable configuration.
If there is a terminator on the cable then it isnt required.

I want him to change the jumper to see if it behaves differently when a configuration change is made. Nothing more.
Im not expecting a change of anything other than the drive ID.

But the ID jumpers is pin 1 sets 3 bits, pin 2 sets 2 bits, pin 3 sets 1 bit and pin 4 sets 0 bits...
Or an I reading it the wrong way around?

Yes I think I am reading it the wrong way around...

I think it only needs 1 jumper block on the middle set of pins.
Just to see what happens as much as anything else.

Yes
simple binary id bit 3 = 2³, id bit 2=2², ...
jumper set is 1, jumper not set = 0

Yeah I know how it works, Ive been using SCSI devices for over 30 years 😀

Edit

Nearly 40 year...
Now I really do feel old! 🙁

Well, you learn something everyday.

Do SCSI disks support something like ATA HPA? I dont see why they would (LBA from the start, no capacity limits) but you never know

As you are looking at it you have a jumper on pins 6 and 5.

Can you move the jumper block (or add another one) to jumper pins 4 as well or instead of 5.

So if you dont have a spare block then dont force SE mode, set the ID to 0 instead.

but jumper seems to me in 2-3 position, not 6 and 5

Update and it work at full capacity, now my Pentium200 have a super fast 70gb scsi hard disk drive. tnks
