Mine works fine.  "Homebrew" has essentially nothing to do with it,
unless you were sloppy and made a bad cable or something like that;
all that most of the third-party packed drives are is a drive with
embedded SCSI controller, case, power supply, and connectors.  That's
essentially the same as a homebrew drive system.

You shouldn't have to reformat the drive.

From the sounds of it, you have either a DMA or a memory usage problem.
Disable ALL third-party Desk Accessories, and if it still crashes upon
booting, suspect DMA compatibility problems.  Most memory cards had such
a problem until the most recent revisions, and the TWGS also had a DMA
problem that requires a PAL upgrade to fix.
