Got one of these (actually 2, also a 300MHz on the shelf):
everymac.com
At least I think it is as it says 400 MHz on the label, with 128MB RAM, if it's still in there, forgot to check, label says 128MB.
... and the harddrive (IBM DNES-309170 9GB Ultra2 SCSI) has a loud high pitch noise that fills a room.
I believe it's past 21 y-o and it's time to replace it.
So I want to swap it for something modern and hopefully more quiet to use with OS9.2.x.
Available options that I have at home:
32GB CF-card with IDE-adapter
120GB 2.5" SATA Seagate Momentus 5400.2 ST9120821AS
120GB 2.5" SATA Seagate Momentus 5400.2 ST9120821AS
320GB 2.5" SATA WD3200BVVT (SATA would need an IDE adapter if possible)
6.49GB 2.5" IDE IBM Travelstar DBCA-206480
10.06GB 2,5" IDE IBM Travelstar DJSA-210
40GB 2.5" IDE Toshiba MK4025GAS
2.16GB 3.5" IDE Samsung WU32165A
10GB 3.5" IDE Fujitsu MPF3102AT
16GB 3.5" IDE Fujitsu MPE3170AT
20GB 3.5" IDE WD Caviar WD200
40GB 3.5" IDE Samsung SpinPoint SP0411N
100GB 3.5" IDE Maxtor 4W100H6
6GB 3.5" IDE Quantum Fireball CX (Apple branded)
80GB 3.5" IDE WD Caviar WD800 (Apple branded)
I assume I'll loose performance if I use ATA/IDE but it would be worth it to stop the noise.
I remember messing with this before trying to use an IDE SSD - didn't work, computer would freeze and spontaneously crash. Tried some harddrive as well, I recall I had to shut off virtual memory to get it started.
Not that I'm experienced with such things.
Plan was to install one of the drives I have (I have a few more, this is what was at hand), copy everything over, scrap the SCSI-disk and SCSI-card (put it on the shelf for safe keeping, I rarely throw anything away). Then enjoy just hearing fan noise...
So, disconnect SCSI drive, install OS9.2 on the IDE drive, reconnect SCSI drive and copy stuff over... I read somewhere it's a drag and drop maneuver basically.
If you have other recommendations, I'm all ears.
