Seagate 540SL - Manual (Page 12)

Mounting the drive
Required materials:
•
Four 6-32 UNC-2A screws (not included)
The drive fits in a standard 3.5-inch bay and can be mounted in
any orientation. Position the drive so that the cables are not
strained or crimped. Secure it with four mounting screws not more
than 6 full turns (0.20 inches) into the drive frame (see Figure 4).
Caution. To prevent drive mounting-hole damage, use only the
type of screws specified.
This completes the hardware installation.
