Hi Newat,
...back...
Ok, lot of posts, good to have lot's of help.
The PSU from you IDE-to-USB will do fine I think.
The picture shows me it's connected correctly.
But I read you still get the I/O-error, meaning data is read corrupted from IDE-device.
Since the data is stored correct (&checked) on the PC, the error must be
made in de interface, that passes the data from IDE-device to Atari.
9 out of 10 times this is a problem with power (you tackled this) and/or bad
contacts on the atari side (the interface now has gold plated).
So the most logical step will be to clean the contacts of your atari.
-rubbing mildly with sanding paper is the most easy way.
-blow away the dust.
About booting from real D1:
Any dos will do fine. You must have have dos 2.5 lying around somewere.
Boot from disk using the shift+control+D procedure.
Then when DOS is loaded, shift+control+R
Try to read DIR of D1: several times (D1: on IDE)
If the readout is consistent the interface is OK
You can format from DOS and write DOS-files to it as you like.
After doing so try and boot the Atari from IDE.
switch off (yes, wait 10 seconds) switch on and press 0 (no cartridge).
When the I/O-error is persistant, the interface is most likely bad.
Contact Steve for a replacement.
Perhaps you need to filter out the possibility that the trancend you have
is incompatible with the MyIDE-interface. This is a rare phenomena.
Do you have a harddisk lying around doing nothing?
Connect it to the myide with the USB-to-IDE-PSU.
Run fdisk, make D1 SD 720 sector.
boot DOS from disk (using the disable-trick)
format this partition and write dos 2.5
reboot the atari from ide.
When you have again I/O-error, the interface is indeed bad.
At the otherhand, when it all works, the trancend is incompatible......
Let me know,
Sijmen.
