I recently acquired a used hard disk QUANTUM ProDrive 210S to put INTO
I configured it as device 0 and parity disabled.
Using HDX 5.04 I tried to format it and failed. HDX recognized the disk
correctly, but refused to format, giving a message like "Can't do
formatting. Check connections......"
I was about to give up when I got the idea to try accessing the disk.
It worked. I could read and write with no problem. So I discovered that
the disk was divided into 2 AHDI-compatible partitions of 104,472 MB each.
Then, I tried to re-partition and failed with "This disk was formatted
using a previous version of HDX. Please reformat." This, I can understand.
So, these are my questions:
(1) Does anyone has an idea of what could prevent that disk to be
formatted, while allowing to read and write?
I suspected a jumper named SS (spindle sync) but it has nothing to do
with the problem. Perhaps another jumper? (there are also jumpers
C0, C1, P0), or whatever?
(2) I have seen that SCSI terminating resistors are mounted on the disk,
while there is none on the original 44MB because they seem to be mounted
directly on the internal adapter of the MegaSTE. Should I remove the
resistor on the disk, fearing an overload of SCSI lines, i.e. a danger
of random data corruption?
I would be grateful for any help on the subject. Thank you.
