Yes but _I_ don't know how to do it!

take a very sharp carpet knive thats best ;-)
stick it between the red Pin1 and 2 throu & go to pin1

I have just been given an A1200 with an IBM 2.5 in 258Meg HD, it has pin 1 cut on the ribbon cable. I wondered why...
I also have to reboot after switch on to get the HD to boot up, I remember having to do this with my old Amiga which I had installed a 3.5 in HD in.
Maybe this will ease your mind Akira?

I also have to reset my amiga after I turn it on to boot from HD.

I tought this was normal and I kinda like it since this way I still see the nice powerup message and the floppy ...

Strange...

Actually this is not uncommon in that it has to do with the spinup of the HD. There is always a delay between when the power is applied to the HD and when the spindle motor is up to speed so that the R/W heads will fly properly. It's more of an issue on older HD's, both SCSI and IDE.

One nice feature would have been a small settings table within the Kickstart that would keep certain settings for future boots, i.e., HD startup delay and default boot order. These are present in most PC system BIOS tables and will stay once set and saved as long as the battery is good. I think a 5 - 7 second delay would have been fine for most HD's but some required as much as 20 seconds to spinup to speed

Ahh, I tought it might be something like that, only the thing is that the drive is fairly new, it is 1.2Gb one, works like a charm.

btw. it is pretty annoying when you have 1Gb stuff on one partition (games) and then one game does something bad and invalidatets it... it takes 10 minutes to valiade it and sometimes you need to use stuff like DiskSalv, which can take almost an hour to fix that small little error.

Yes but by todays HD standards that 1.2GB drive is ancient history. Remember that the minimum HD capacity is now about 20GB soon to be 40GB. Don't laugh as this is the norm for most PC boxes now. Because the capacity is so great you'd think there would be a lot of platters to store this data, but actually no, there are fewer as the areal density has increased so much now.

But one nice feature that keeps getting added is energy savings, i.e., the spindle motors are getting more efficient as are the controller boards mounted on the bottom of the drives. This means that the new 20 or 40 GB HD's may even draw less power then the old 1.2GB you are mentioning

I have a pair of old drives in my 4000 now, both Western Digital. One is a 3.2GB and the other is a 4GB. Both power up pretty quickly but I still have to reset because the delay is off by about 2 - 3 seconds

Ofcourse you are right about today's standards... I was thinking more of Amiga standards... when this machine was build a 200Mb drive was a novelty...
Hmm, as you mentioned the new drives draw less power, so it might be a good idea to put in a 4Gb drive ... I don't thing standard file systems support anything bigger than 4Gb ?
Anyone here has any experience with some other file system that would be of good use on A1200 with a "fairly" big HD and which is only used for gaming (some games are DOS, most are WHD or JST) ?

I think os3.9 supports partitions bigger than 4gb but I don't have the chance to test it myself until I get a real amiga.

jmmijo · 24 February 2002, 00:16

I also have a number of lareger hard drives to try out so I'll let you know what I run into. I've seem to think that it's the partition size rather then the actual HD size that matters, i.e., if you use a 40GB hard drive and partition into 10 equal parts, then you have essentially ten 4GB HD's.

Again, this is what it should do but who knows for sure without trying it out. I suppose for the sake of this fantastic board I could swap out my older drives and startup a new OS build on a 40GB drive
