Help!,
My Apple HD-20 will no longer boot.
It doesn't even appear on the desktop!
(not even when I boot my Mac from a floppy, in that case it ask whether it
should initialize the HD)
This occurred after a power failure, just when the system was writing the disk.
I guess that the boot-blocks are damaged.
Apple's Disk-first-aid sees the device, but says "sorry, can't help"
Apple HD-Install program has the options "verify disk" which scans
all the sectors/tracks.
It reads them all --takes a few minutes-- and finds it correct.
The other option with HD-Install is "update", which also apologies for
not being able to help.
(of the other two options I used "stop",
but I am reluctant to use "initialize")
My last resource has been my Apple dealer and
the *official* Apple Netherlands importer.
Both failed to help.
What can be done?
I guess there are some utilities that scan the HardDisk and can
retract information (or even repair the boot-sector).

The phenomenon is the red light keep blinking while there is no normal noise of booting up. Since it was within one year waranty, I called up the manuafacture. A nice voice answered: "The problem might be with the head parking. You can ship it back to us. But I am afraid that it will be OK by the time it gets here. So why don't you pick it up and shake it gentally a few time and then see what happens". So for the first time, I did what I have been carefully avoiding -- shake and turn upside down a few times the hard disk. And, it worked again. Since then I have been very efficient in disconnecting the cables, shake the disk and connect it back again. DISCLAIMER: This story is only for information. I don't guaranttee in any way that your hard disk is shakable.

And, it worked This leads me to believe that sticky autopark may be a common cause of hard disk "failure." Recently my Applecrate-60 (Seagate ST277N) exhibited the same symptoms. Although it's still under warranty I opened it up to check the power supply (which was fine), and as a last resort tried some gentle tapping, which did the trick - apparently freeing the head.
