On AppleLink there's a memo that says the following (paraphrasing):
SafeEject is not needed and should not be used on the Mac IIx, IIcx,
SE/30, IIci, and Portable, or any machine upgraded with the FDHD upgrade
kit. There's code in the ROM of these machines to move the heads to track
79 before ejecting the disk.
In System 6.0.4, the resource ptch=7 patches the disk driver on the Mac
Plus, SE and II to provide the same fix. I disassembled this resource,
and a quick glance at it show that it installs some new code in the low
level I/O vectors, so I believe that the fix is in 6.0.4.
I hope this answers the question once and for all.
