Can I safely turn on/off the SCSI HD connected to my mpc?

After some nasty ZIP experience I eventually got this external SCSI HD on ebay. Came in a nice Apple-grey enclosure, size is 1.5GB. I managed to format it, partition it, everything works absolutely fine. Only issue, the disc is noisy - very loud, hoover kind of noise.

I tried to only turn it on when I need it (ie when loading or saving), then turn it off when I want some peace, then turn on again when I need to save my work or load other data, then turn off again. It worked flawlessly, but I'm afraid I could eventually damage the HD or even worse blow up the SCSI fuse with all this turning-on turning-off.

I'm using the HD power switch and not unplugging any cable (which can definitely be harmful), but still I don't feel 100% safe.

Can anyone give advice?

Cheers

No Idea sadly, but I find it amazing you've been able to get away with it. Maybe you can put it in a closed box to reduce the noise?

SCSI HD's are just noisy...and they are gonna stay noisy as long as it's spinning. If you don't save or do anything for like 30 mins then the thing will stop spinning but once you use it again it will continue to hum and click for another 20 or 30 minutes. I know what your going through because my DPS12 is louder than a lawnmower...

The box solution coul work, but I would risk over-heating, which is not cool. I already opened the box and unplugged the fan to reduce the noise.

It worked beacuse of this 3.1 OS feature:

(Straight from the manual)



Connecting Multiple SCSI Devices, Making a SCSI Device Active Without Recycling Power

In previous versions of the system software, the only way to make a SCSI hard disk active (recognized as ready for use by the MPC3000) was to turn the MPC3000’s power on while the SCSI disk was connected and turned on. Also, it was impossible to connect two or more SCSI devices to the MPC3000 and switch between them while working.

Now, up to seven SCSI devices may be connected simultaneously, and you may make any one of the connected devices active at any time without recycling power.

Still, I'm not sure it's safe to turn on/off. This feature allow you to select which disk of the SCSI chain to access, but I think it's still supposed to remain on while it's not used... ?

Clueless.

yeah I think your fuse might be at risk.

Actually a truly silent SCSI solution exists.



SCSI Solid State FFD. No moving parts, dead silent. You can read more about them here:

Seems like they're actually used in US fight airplanes since they have <0.1ms access time and they work in extreme conditions (-40°C to +85 °C). That's overkill for an MPC maybe, but I'd fancy one. The smallest (and suppose cheapest) 128MB model would hold shit load of mono drum samples. The 2.5" could even be mounted inside the MPC without replacing the floppy - Built-in non-volatile memory, that would be a storage revolution!

I tried to investigate, but so far couldn't get to know how much do they cost, and who is selling them.

Ok, some googling and found the retail price:

$598.44 for the cheapest 128MB. $40K for the 90GB.

Forget about it. Let's hear some HD noise.

I use a scsi hd for my 3k le, and I turn it on and off all the time and it hasn't failed me yet!
I can't say if it's safe for everyone but....
Peace!

That's good news.
