Steve Becher states that the Seagate 225N drive, the drive used in
Apple's SCSI HD-20 may need custom ROMS in order to implement file
tags in an article in Delphi Digest V2 #52.

Ephraim Vishniac states also in a previous article that this drive
does not need custom roms for this function as it already has this
capabity.

All one needs for file tags with a Segate 225N drive is Apples
software.  I was playing with MacMate drive which is sold by Relax
Technologies in Union City.  All this drive contains is a power
supply, a Seagate 225N drive and a very cheap case.  I tried just
out of fun to initialize the drive with the floppy that came with
the Apple HD20 SCSI.  The MacMate drive formatted and initialized
without any difficulty, and Fedit Plus confirmed that this drive now
had file tags, which it did not when previously formatted with the
MacMate software.  Another problem is that for some reason the
MacMate software won't reformat the drive, but the experiment proves
that the Seagate 225N drive does not need special ROMS for file
tags.

By the way I can not recommend the Mac Mate drive several of my
friends had problems with them and received less than satisfactory
help with their problems from the manufacturer.  Apparently the
drive is marked with a serial number internally on the drive when it
leaves the company, and the enclosed software will not initialize
the drive if it does not match the serial number.  Their
initialization software comes on the drive itself, and not on any
enclosed software.  So if you don't think of copying the program or
if you buy two drives and only copy the program off one drive, if
you want to reformat a drive you cant.  They won't send you a copy
of the format program.  You have to send them back the drive, so
they can format it and inscribe a new serial number.  Of course this
is not covered by the warranty because it is your fault for not
knowing that each drive has its very own formatting program
Also their driver
will not recognize another company's driver, nor will it  mount if
another company's driver is used on startup; unless you pay $15 for
an upgrade of the driver.  Of course you will not have these
problems if you buy the drive and then use Apple's software. 

Another thing about file tags: the only 3rd party company who has
drives that will be supporting file tags is Levco.
