(Oops no power, maybe it's explained in) the manual?

See the last bit of 9.6.2 where it says -
A single drive connected via a cable to a host 80-pin I/O connector is
not recommended.

9.6.2 SCSI interface physical description
Cheetah 10K.6 SCSI drives support the physical interface requirements of
the Ultra320 SCSI Parallel Interface-
4 (SPI-4), and operate compatibly at the interface with devices that
support earlier SCSI-2 and SCSI-3
standards. It should be noted that this is only true if the systems
engineering has been correctly done, and if
earlier SCSI-2 and SCSI-3 devices respond in an acceptable manner (per
applicable SCSI Standards) to reject
newer Ultra320 protocol extensions that they don’t support.
<snipped>
LC model drives plug into PCBA or bulkhead connectors in the host. They
may be connected in a daisy chain
by the host backplane wiring or PCBA circuit runs that have adequate DC
current carrying capacity to support
the number of drives plugged into the PCBA or bulkhead connectors. A
single 80-pin I/O connector cable cannot
support the DC current needs of several drives, so no daisy chain cables
beyond the bulkhead connectors
should be used.
A single drive connected via a cable to a host 80-pin I/O connector is
not recommended.
See the Install guide -
What you need
• Screwdriver and four 6-32 UNC drive mounting screws
• Forced-air ventilation to provide adequate drive cooling
• An unused drive power connector (not applicable to LC models)
To operate at LVD transfer rates, you may also need an LVD-capable SCSI
host adapter, LVD I/O cable and active negation external terminator.
6. Mount the drive in the host system and connect cables
Note. LC drives are designed to be attached to a carrier or tray and
inserted into the host system without I/O or power cables.

I always used Adaptec controllers

worked.
Iwill also do controllers.
