I have a Maxtor 200 MB hard disk originally shipped for use with a Sun that I want to use as an internal HD for my IIfx. After much futzing around, I got it formatted, and the system to boot from it as an external with an external power supply. I then moved on to try and mount it internally, only to find that the system won't recognize it. I can plug it into the internal SCSI connector and external pwr supply, and everything is fine, but if I use the internal pwr, it spins up and the heads come in, but it isn't recognized. The VOM says that the external pwr supply is giving 12.5, 0, 0, 5.2 v on the 4 leads, while the internal one is 12, .25, .25, 5, with reference to the chasis ground. Is this the problem, or is something more subtle going on? Is there a fix? Any help appreciated, especially responses by email to ether@research.att.com. thanks, ...David Etherington.
