Hp 9133h disk drive formatting problem
Message #1 Posted by Pascal on 2 Sept 2008, 1:17 p.m.

Hi everyone,

I have a 9133H HP-IB disk drive that I want to use with an HP-150B touchscreen. I could not find specific instructions for formatting the 9133H but I found something for the 9133D which seems to be very similar. The manual says that you have to use switch position 9 in order to format the drive. Then you should boot from the floppy disk (I use dos 2.1), launch Device config and configure A drive to be on Addr 0 / drive 0 and B drive on Addr 0 / drive 1. Then I use the format application in order to format the hard drive, but the system displays formatting ... and then seems to hang. The light of the hard drive does not blink so I suppose it's not even trying to format.

Other than this, when I turn on the disk drive the drive led turns on and I can hear the head accessing the disk so I suppose there is no mechanical problem with the disk.

I read that this drive is only compatible with dos 3.2 and also that the hp-150A is not compatible with dos 3.2. but my understanding is that it's only relevant if you want to use the disk as one partition (20Mb). If you split the disk in smaller partitions, dos 2.1 is able to manage them, is that correct or are there other limitations (i.e. hp 9133h only compatible with HP-150 II)?

I also read that switch positions 1 to 8 are used in order to partition the disk into 1, 2, 3 etc. partitions of the same size. But I tried all positions and none of them worked. But there is one thing I don't understand : if you should use position 9 in order to format, how can you format using other partition sizes ? Is there a low-level formatiing that should be done first with position 9 and then a partition splitting using the switch position 1 to 8 ?

As you can see, I'm a little confused and I would gladly accept some help in order to solve this issue. Thanks in advance !
