HD spindown/shutoff

[Malkier]

Hi All!

I've recently started to experience problems with my A1200. The A1200 has a Blizzard 1230 and a Western Digital Caviar 31600 3.5" attached via a 2.5" -> 3.5" adapter. The power for the HD is taken from the floppydrive. The power for the A1200 is an A600 PSU.

What happens is when I insert a disc in the floppy the HD does a spindown and starts to spin up again and stops answering - the computer becomes useless due to no HD-access. Note that this behaviour can occour randomly also, even without HD or floppy-access.

I'm suspecting some problem with the power supplied to the HD.

Be well.

Yes, I haven't towerized my A1200.
The original A1200 PSU was lost many years ago.. Maybe it burned up.. hmm
I've used the A600 PSU ever since without any problem at all - until now.

Could it be the (old) HD wanting to fly to heaven?
(5V at 0.4A, 12V at 0.27A)

Ok, so it seems to be the PSU. Maybe I'll go for a tower right away, thanks!

You don`t have to towerize you amiga, You could always modify a pc power supply, Thats what i`ve done and works great.

Thank you for the reply,
how would I have to modify a PC PSU in order to use it with the A1200? Btw, have you moved your A1200 into a "PC-tower"?

Be well.

An A500 Power Supply has 20% more power output than an A600 PSU. The A1200 came standanrd with an A600 power supply but the best PSU you can get for an A1200 without adapting a PC power supply is the Bigfoot Power Supply.

I'd love to order from Software Hut but I must say that my wallet is a bit shallow atm.
