HP probably had a non-conforming implementation of the IDE/ATA interface
on their system. It's probably a firmware bug. Nothing should crash
if there are communication issues with a hard drive!

This is a further report on the continuing saga of trying to use a
compact flash drive in my HP 1662C logic analyzer.
I got an IDE to USB interface on eBay like this:
It worked perfectly to copy the image of the good hard disk into
a file. Under Linux I used the command:
dd if=/dev/sdd of=HP_1662_disk.bin bs=1M
This gave a sector image of the disk, about 2Gb of data.
It compressed to a file of 3.7Mb. The original disk had all of
the HP system files but otherwise was mostly empty so it compressed
well. I can make this image available if anyone is interested.
I copied the image onto another hard disk using dd. This disk
was larger, about 40 Gb. The logic analyzer booted this disk OK.
Now I wanted to try a flash drive. I got one of these:
And one of these:
The compact flash and adapter worked perfectly when copying
the disk image using the Linux dd command.
However the flash drive would not work with the logic analyzer.
The power up diagnostics tested the "hard disk" and it passed
the test. When I tried to look at the files on the hard disk
the system crashed. It also crashed if I tried to format
the "hard disk".
So, the flash drive was a failure but the imaging to another
larger hard disk was a success.
Does anyone have any ideas about the problem with the compact
flash drive? Have these flash drives worked in any other HP
devices?

I would like to image the disk. I don't have any systems with IDE
interfaces but I notice that there are USB to IDE interface devices
on eBay for cheep. Items like; 270571299126, 271122120367,
300490773644, 251165923530, 170881980054.
I want to read the IDE disk image into a file and then write
the image into a flash drive with an IDE emulator interface.
I would put the flash drive and emulator back into my logic
analyzer.
Has anyone tried these USB to IDE interfaces? Are they useful
for what I want to do?
Thanks,
Pete.
