[lug] OT: drive cables

[William Petty]

Cables are available where the drive side is a single SAS drive 
connector with a flying power lead set.
The other ends are a single SATA connector as you described, and a 
male Molex for the power.

I had to borrowed a couple of these for the same reason. The host 
adapter used individual SAS/SATA
connectors.

Welcome the world of SAS cabling....
  - Single as you described.
  - Dual Ported single drive. (Two SATA connectors)
  - Quad-Wide. (with or without SGPIO) (With or without Power)
  - Mini-SAS quad. (Internal and External versions) (Medusa style and combined)
  - Infiniband style. (Reused)

And you thought SCSI was bad???

P.S. This is BAD practice, but I have shaved off the edge of SATA 
cables and power connectors to allow them to
fit on the SAS drive. I only do this for external drive testing as 
you lose the positive lock for the cable and any
tension will dislodge the data cable.  As for the power cable, really 
bad things can happen if it gets tilted. Trust me
I know!!
