Has this ever happened to you?
I was playing my favorite game, Master of Orion II. Then I quit the game and ejected the CD and noticed there was a crack in the inner ring. So I decided it might be a good time to make a backup copy of this CD, if it were possible. I tried Disk Utility first and thought it might be better to use Toast 9.0. I started running the program and suddenly the plastic CD button goober shot out of the mirror door. I got a cryptic "disc has read errors" message. I tried ejecting the disc both using eject button on the keyboard and the eject button on the front of the drive, which by the way is a Samsung from other world. None of this worked. The drive wouldn't open. I tried a paper clip and that wouldn't work. I tried rebooting the machine and that didn't help. I gave up and shut the machine down and pried the drive open. The CD was in chunks. It literally exploded in the the drive. I have probably 40% of it out of the drive in six pieces. I've never heard of this happening. I loved that game. This sucks. Now I don't have any excuses to switch over to my G5, no even lame ones.

G4 MDD SCSI (pref non PCI)
Hi folks, I have a G4 MDD (FW 400, not 800 model), which I would like to add SCSI to. All my PCI slots are taken up. I am mainly using this with OS 9.2.2. I would like to know what is the best featured/most reliable option for adding SCSI for this machine, that doesn't use a PCI slot? I use the machine as a legacy DSP farm for my home music studio. I use a Korg OASYS PCI card, which will not run under OSX. My idea for the SCSI was to interface with my old hardware samplers (EMU/Ensoniq/Akai). I have read about some Firewire and USB SCSI adapters, but information is a little sparse as to how these really perform in practice. Some also don't allow a complete SCSI chain, just one device. If really necessary, I could possibly try to free one PCI slot, but I would really rather not. It seems that some PCI SCSI solutions were more highly regarded. I certainly would not want too much hassle with an unreliable solution, if that's all I would get with USB/Firewire SCSI adapters. BTW, I have heard of PCI expansion racks to add more PCI slots; are these any good? Is there a performance degradation with these? Thanks for any pointers/advice.

It was one of their first episodes. Short story is that with normal discs no drive they tried could destroy a disc. I think they did have some failure after abusing the discs (Microwaving was one method). They finally got a normal disc to fail by mounting it on a die grinder and, IIRC, running the die grinder off of 220V, twice it's rated voltage. -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.

Most of what I know about the Firewire - SCSI adapters is that they are rare. What other PCI cards do you have, maybe there are some options there. -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.

Re: Has this ever happened to you?
There is probably only 2 things that could have caused this: 1st the CD broke going in when the thing comes down to grab the disc by the hole because of a miss alignment or 2nd It spun up to over 10,000rpm maybe it was 20,000 (Just like Clark said about Myth Busters figured out how much rpm would cause it to explode)... Now what I think happened was the first thing? Once they crack it will weaken them and the spinning of the drive would cause them to explode..? -Original Message- >From: smac0031 >Sent: Aug 27, 2012 10:29 PM >To: G-Group >Subject: Has this ever happened to you? > >I was playing my favorite game, Master of Orion II.

Re: G4 MDD SCSI (pref non PCI)
Hi Clark, Thanks for your reply. My other PCI cards are Creamware/Sonic Core Scope DSP cards (3x) and one AGP video card. The Scope cards can run under OSX, but I'm mainly working with 9 due to the OASYS PCI. I'm also more familiar with OS 9 than X. As for slow transfer rates with USB 1, I could possibly live with that. In most cases, it would be fairly small transfers. My main concern is reliability and functionality. This area is pretty new to me. I used to use Amiga for music back in the day, but often heard about other users with pro samplers connected via SCSI to their Macs (I think G3 mainly). There is host control software to run under Mac OS 9 for this. I have the samplers now (they are cheap at this point) and really like the sounds I can coax from them, but would like to integrate them into my computing environment. I don't really know what I'm doing though. I have read a little about Magma PCI expansion chassis which are supported under OS 9. Never used one though. Would an Atto SCSI card + PCI chassis be a reasonable solution? Does adding an expansion chassis cause any issues with the PCI bus performance? As I'm running a lot of live DSP audio processing, which uses main memory to some extent, as well as some CPU load (I think not a lot though) I would not want to cause issues in the bus performance.

Re: G4 MDD SCSI (pref non PCI)
Hi, I was hoping for a SCSI adapter running from the Firewire 400 bus. Haven't found one though. I'm not sure I really trust USB adapters for this purpose. Not so much from the transfer rates, but more because there have been so many poor quality USB interfaces (speaking generally), and due to the transfers being managed more directly by the CPU. My understanding is that Firewire not only has the superior bandwidth, but that it also features dedicated host control hardware to manage the transfers. Any advice on this matter would be appreciated. The alternative I was considering was to have the SCOPE PCI cards hosted in the MDD PCI slots, a Magma PCI expansion host card in the last on board slot, and a PCI SCSI card + Korg OASYS PCI mounted within the expansion chassis. I don't know how well this would perform though. I guess it would be fine. I believe professional studios were doing something similar for running Pro Tools rigs back in the day. I have a 19" equipment rack standing next to my MDD. I would likely house an expansion chassis there. I originally chose the MDD as I had access to a cheap dual 1.42 GHz model with TI4600, 2 GB RAM (1.5GB usable, I know) locally. The faster memory bandwidth appealed to me for live audio processing/generation. I don't really know how much of an issue this is in practice though. Also, I used to use my father's old PPC 6600/60, and I have nightmares about slow performance in general. Would you be able to recommend a different model with more PCI slots? I would rather not go too far back in terms of performance. If the memory bus is OK, and I can fit a decent single CPU accelerator, that would be fine. I also considered picking up an old G3 laptop with on board SCSI just for interfacing with the samplers. However, my space is getting somewhat crowded/complicated for computers/instruments. I can add SCSI to my main studio PC, but some software will only run well under Mac OS 9.
