MacintoshMan1999 Report post Posted September 30, 2019 When I try to install 6.0.8 on my Quantum Grand Prix HD it gives me the error message: "There's a problem with the disk"Ehman HDD." Installation cannot continue. The disk "Ehman HDD" may not be a usable startup disk. (Error #-199)" I'm not sure what's wrong with it, suggestions? Share this post Link to post Share on other sites
Scott Baret Report post Posted September 30, 2019 Have you formatted this drive recently? -199 represents a drive map error. Alternately, try copying the files directly from the System 6 floppies to the drive. There is nothing to decompress on a System 6 disk so the files can be copied without any problems. If you have the 1.4MB floppies, just drag the System Folder over, then go to your System Additions disk for anything else you may want, like MacroMaker.

For some reason the drive copy’s some files, but not others. It seems to not copy system files but does copy non-system files. Share this post Link to post Share on other sites

Just to be clear, the hard drive info is: 2GB Quantum Grand Prix 50-Pin SCSI Share this post Link to post Share on other sites
jimjimx Report post Posted October 10, 2019 What computer are you using, and what, if any, modifications have been done? Have you tried to format the disk to < 2GB? Some ROMs don’t see more than 2GB correctly. Share this post Link to post Share on other sites

It's A Macintosh Plus w/ 4MB of ram, I've made a partition that's exactly 2GB, I'll make it slightly smaller... Share this post Link to post Share on other sites
LaPorta Report post Posted October 12, 2019 I'd run Norton Utilities on it and see if there is a file map or directory error. Share this post Link to post Share on other sites

Well, while I was using the Macintosh there were no problems, at first, but problems soon started to occur (repeatedly restarting) lt has always happened but usually stops. in layman’s terms, I don’t know exactly what caused it.

dochilli Report post Posted November 13, 2019 (edited) Could be a problem with the analog board. Perhaps the voltages are out of range. You can measure them at the floppy port. Must be near 5 and 12. AB needs a recap. Could also be a RAM problem. Clean and reseat the RAM. Edited November 13, 2019 by dochilli Share this post Link to post Share on other sites

Ahhh, the RAM is a good point. its been upgraded anyway so I’ll check it. If it’s not the problem I’ll check the floppy port. Share this post Link to post Share on other sites
