Hi!


I have C1541C disk drive.
I connected it to my Commodore 128 as drive #8.
Turn on drive, seems that works correctly: GREEN LED lights - power indication, RED LED tries first access.
Then I turned on my C128. And computer hangs, as everybody knows tries to BOOT from drive #8.
So, I tried it vice-versa, first turn on computer, then disk drive.
Computer prints prompt READY and I tried to LOAD any program from drive. Computer again hangs.
So, I hit STOP+RESTORE and send command to drive, every command I tried, always hangs.
I tried else one thing. C64 mode. In C64 mode computer BOOTs not. So, at computer start I hold CCBM key.
This switches computer directly to C64 mode. All was ok, then I wrote command LOAD"$",8.
And again - computer hangs.


About hanging: It seems like drive got command not - no activity.
When I had connected to computer C1581 drive all was working correctly.


CAN ANYBODY HELP ME WITH THIS PROBLEM?


Many many thanks for every reply.

Have you tried the drive on another commodore? Have you tried a different Data cable?

Several years ago, I had a drive such as yours.  I had to give it to Ray Carlsen for repair.  According to my fuzzy memory, I believe he had to repair the disk sensor and a chip or two.
