Hi there, excuse me if i'm a bit abrupt but i'm a bit in a bind. I have an old Mac Performa 450 that use to be my grandfathers which I really love for nostalgia reasons. As of late this old computer has more or less had it, and is almost dead. I suspect something funny with the motherboard or possibly the HDD. Either way, I am unable to get it to boot 99% of the time, the HDD starts revving up but then just stops, system does not even recognize it those 99% of attempts when using a bootdisk. Today, just now I got a lucky break and managed to actually start the system up again through some miracle. And now i want to make a complete system backup of "everything", but I am not sure how to do that. I tried copying the HDD onto floppy(like you can do with PC's), but was met with an error of there not being enough space. So I would like to know if there is any way I can backup the entire system as is accross multiple floppies? Thanks! |

Hi Alex, since you do not seem to have an external HD backup volume, Norton Utilities 2 or SUMII might be fine for backing up you HD to floppies. If you got enough space on your HD, you might rather create a disk image of the HD and compress and segment the image with Stuffit. That image might be useful for mounting it with the emulators. Norton Utilities 2, Stuffit or SUMII can be found at Macintoshgarden. Good luck!

Thanks for the advice! Though i seem to have another obstacle to overcome. This is my only mac, and i have a PC, and trying to do things with Mac files via PC seems to mess them up somehow. Any idea on how to get around this?

Mac files are usually damaged by PCs, sadly. All Mac compressed SIT files MUST be inflated on your Mac, to work properly. The files from MG usually are done with Stuffit5. Look for the free Stuffit Expander in the first place and take it to your Mac to decompress there. Stuffit Expander should handle the SUMII disk images. DiskCopy images will open on the Mac by double-clicking them. I hope, all the tinkering won´t stress your HD too much. May be you should look for sombody who can take out the HD and do the backup with another Mac. If you PC has a SCSI host adapter, you might consider reading your disk there with BasiliskII build 142. I have done exactly that, with a HFS disk from an old Mac. Best wishes!

Mmm that almost sounds best. Looking at a few cheap SCSI Host Adapters on e-bay. Does one need any kind of special drivers or software to use them, or are they plug and play?

Plug and play will depend on the OS you are running. My Tekram adapter came with a driver for W2K. XP rcognized it by default. Many divers can be found at DriverUpdate or similar sites. If Windows works with the adapter, Basilisk can use it. If you go for a SCSI host adapter, you might also look for an old SCSI external case with a disk. You could use that with your Performa´s DB-25 SCSI port. If you are a EU resident, I could give you a SQ555 SCSI drive with some 40MB cartridges. I used those a lot in the MacII days. They are a bit slow, but you should be able to boot your Performa from one of those.

Well i made a small discovery that i had completely missed. Turns out my old Dell Precision workstation has support for SCSI drives. The bad news is that the SCSI connector on the motherboard does not seem to be the same kind as the Mac's HDD(which looks like a standard IDE cable but with different pin configuration)and i'm not quite sure what to do about that.

I think what my motherboard has is a SCSI U160 68pin connector, and i think the HDD has a IDC50

Ultra-160 SCSI host adapters are using a 16bit bus, so you might have trouble with a 8bit bus device. Can you configure the host adapter to narrow? I am using my Formac host adapter´s "narrow" port for a external HDD with a 68 to 50pin cable. If you can set your SCSI controller to narrow, you might try to adapt your 68pins to a 50pin Mac disk. I have seen such adapters in the past, but I did not look for those recently.
