I want to replace my 80GB harddisk with a brand new 200GB harddisk.
Onlything mounted now is the 80Gb ide harddisk as master and a ide cd rewriter as slave onto the 1st channel.
What is the easiest way to do this?
Can I set the new harddisk to the second ide channel and format it from there?
If so guess I'll have to give the partitions an other name at first and rename them after removal offthe old harddisk?
Don't want to do a fresh install as it is working quite nice now the way it is.

Yes you have to name it different to your Partion Names and rename it after replacement.
I did it that way when i replaced my 120Gig HD with a 250Gig

Thanks for reply.
They fill up fast don't they?
On my amiga4000PPC 20GB was more then enough but as you get used to mp3's and music and pictures..phew!

If you got many small files it can take ages to copy them from one to the other HD.
I am looking now for a bigger HD with 500GB or maybe 1TB

Well I finally give it a go.
I connected the new 200GB harddisk to the 2nd idechannel as master.
It shows up ok in scsiconfig but it doesn't accept my partitions.
It won't let me pass the 4 gb it seems..strange.
And when I try to save with these partitionsizes it gives me a writeerror.
Harddisk total size shows up correctly though.
Maybe old version off scsiconfig? version 1.36 (okt 3 2002).

I did manage to partition my old 80Gb harddisk but can't remember how...too long ago


Oooh too fast with asking I just RTFM sorry!

Still not possible to write the changes to disk ..write error.
Maybe because there are two harddisks on the peg?
Should I try partitioning from the morphos cd and only the new harddisk installed?

When using ScsiConfig, did u try pressing Config Drive and Reload Geometry ?
It could resolve your problem making Scsi Config read the exact dimension of your drive...

Bye,
AKiLL

Optimal geometry is what you should use, not reload.

My 160 GB disk was starting to feel full (I have been capturing dv and making DVDs recently) so this weekend I bought a 500 GB drive (Seagate Barracuda ST3500630A, UltraATA, 7200 rpm). On power on the firmware can't find any drives even with 3 seconds delay. I just type reset at the firmware prompt and everything is fine but I will experiment with a longer delay.

SCSIconfig seems to have several bugs. I could not see geometry past 256 GB. I tried "optimal geometry" and "reload geometry" but both would not give more than 256 GB (the number of cylinders was maxed at 32767).

Every time I created a partition, the summary showed the wrong sizes (e.g. create 20 GB partition, shows as 4 MB etc). Anyway, I ignored reported sizes and created 256 GB worth of MorphOS partitions. Then I booted Linux and finished partitioning the remaining ~200 GB. After this, SCSIconfig could read the new partition table but I didn't try to set up the partitions >256 GB with SCSIconfig.

I don't mind because I wanted the extra 200 GB for my Linux side but if you are not dual booting like me, you may have problems setting up your partitions.

On the MorphOS side, what is the difference bewteen Quick Format and Format ? Apart from a very long wait ? I guess that Quick Format only creates a blank FAT but Format writes zeros to the disk in a proper structure. Therefore, Quick Format will work but if I need to use recovery tools, I could be in trouble. Can anyone confirm this hypothesis ?

I made the first partition FFS, bootable, named MorphOS2.0 in anticipation of updating my OS :)

The drive was only Y10,000; 750 GB was Y25,000. So I could have got 1 TB for cheaper, if I don't mind using 2 IDE channels.

(P.S. I'm using MorphOS 1.4.5)

Why not 2 harddisks?
I've 2 harddisks (first is 40 GB, the second is 160 Gb), a DVD-writer and a CD-writer. Works fine on my Peg 2 (Morphos 1.4.5)

> but both would not give more than 256 GB (the number of cylinders was maxed at 32767).

yes, automatic (optimal geometry) is limited to 32767 cylinder (--> around 256 GiB),
but you can set more cylinder at field "Cylinder"

Example Hitachi HDT72505 (500GB):
a) automaticly (reload + optimal) was set:
Cylinder: 32768
Heads: 1
Blocks per Track: 16383
--> tracks used: 536821761 (just around 256 GiB) total: 976773169
--> not used: 439951408 --> HD was only 54% used (at around 479 GiB = 500 GB)!

b) set by Hand to maximal, to fullfill used sectors:
Cylinder: _59621_
Heads: 1
Blocks per Track: 16383
--> tracks used: 976770843 total: 976773169
--> not used just: 2326 --> HD 99,999% = full used!

only fullfill "used sectors" is necessary, not exactly geometry!
current hd with lba(48) is only adressed by block number, not more by sector /head /cylinder!


Bug 2 at Window Partition:
Field "used blocks" Size >4 GB is false (is just modulo 4GB),
but the Size at Field "MBytes" is ok

Example:
Field "used blocks": "Name=HF5: 32020 to 59620 cyl (3698MB)"
Size = 3,698 GB is false /just modulo 4 GiB!

But at Field "Mbytes": "220786"
Size = 220,786 GB is ok.

> what is the difference bewteen Quick Format and Format

Format write Pattern at all Partition Blocks (and test it) before set header
--> hd errors found
--> overwrite also old /random contents
Quick: write only filesystem header

if you must restore lost files /repair partition
full format before begin use partition can also be helpfull (no old obsolete /random contents found),
but current hd work also with quick format

Hint:
i use _second_ ide hd (unit 2) with boot partition (bootmenue and images), MorphOS Partition (System) and any more Partition as "primary" System

primary ide hd (unit 0) is used as complettly and bootable backup with lower boot prio (necessary ever set all path /assign at "Sys" not at (Example) "HDx"!)
backup system at unit 0 can start at /with bootmenue or automaticly if morphos partition (with higher boot prio) at unit 2 lost

@tom

I am using both 160 GB & 500 GB on one IDE channel and DVD & DVD writer on the other channel. If I needed 1 TB I would have got the other drive but I'm don't need that much space yet...

@mk

> you can set more cylinder at field "Cylinder"

I was not sure the number of cylinders; I already encountered at least one bug so how can I trust the other results ? I tried to create extra partitions but SCSIconfig would not let me.

> I was not sure the number of cylinders; I already encountered at least one bug

not really a bug, limited only at old (2002) program /source /used routine /defined vars

(morphos 2.0 come with new program)

> so how can I trust the other results ? I tried to create extra partitions but SCSIconfig would not let me.

only fullfill "used sectors" is necessary, not exactly geometry!
old big hd adress was tricky, no hd with head >16 exist, but adress with 256 heads was possible!
currently hd (all with lba) is only adressed by block number, not more by sector /head /cylinder!

hint:
before MorphOS 1.4.4 hd (not sfs!) was limited with old lba at 2^28 blocks a 512 bytes:
-> exactly 128 GiB (Gi = Gibi = 2^30)
-> around 137 GB (G = Giga = 10^9)
-> around 137.439.000.000 Bytes

at MorphOS 1.4.4(+) lba48 with 2^48 blocks a 512 bytes is used:
-> exactly 128 PiB (Pi = Pebi = 2^50)
-> around 144 PB (P = Peta = 10^15)
-> around 144.115.000.000.000.000 Bytes
(around 144115 TB)
