I saw a post recently where a 500 user complained that his drive would not always cold boot, but would usually warm boot correctly. He was advised that the problem was most likely a mis-aligned drive. My internal 500 drive appeared to be working fine until one day it simply would not boot up. After many, many tries, it worked, but since then it hasn't worked again. I can hear the drive clicking and when I insert a boot disk it sounds as though it thinks the disk is a non-dos disk, i.e. it doesn't read anything off the disk. Is this a mis-aligned drive, and if so, is there any way to adjust it myself? I noticed that I can't even remove the screws from the case, because they're star-shaped. Unfortunately, my 500 is not under warranty any more, and there aren't any dealers or service shops in the area. Thanks.

Safe Harbor has an ad in Amigaworld for OEM (Chinon) drives specifically for the A500. They're $90. My local dealer wanted $150. I have an epson drive in my 500 which failed from day one; but, I thought, and people on the local BBS convinced me, that I was doing something wrong, like removing the disk too soon. Ha! So, I just let my warranty run out like an idiot!! That's pretty irrelevant, huh? Guess I'm a little bitter :) -Larry

If the problem moves to your serial ports etc. then replace it. Be sure you are properly grounded agianst static when moving the chips. Another thing you could do is swap your internal disk drive with one from a 1010. If the external drive works fine... and then doesn't work internally, it was your internal drive. -- -------------------------------------------------------------------------- David A.
