WD400 HDD - Jumper Settings - Possible bad drive

My sister-in-law's old local build computer will not boot.
It acts like it is getting power, but I do not have a spare PSU to swap out. When powered up, seems to provide normal keyboard lights, fans run, but system stalls with no boot activity ... possible defective HDD.
Her son said he would give her his old (5 year) computer, so sister-in-law wants me to copy off some WORD and picture files from old drive. I pulled the WD400 (40GB) drive out of the box. I have a Sabrent USB to SATA/IDE drive adapter (includes AC adapter). Sabrent requires jumpers set to Master. Drive is a 10 pin setup. Using the diagram on the drive, drive was set at "cable select" in computer with pin 1and 2 jumped. For "Single/Master ", diagram states "No pin jumped ", so I pulled jumper off.

I attached required cables to HDD/external adapter. Plugged USB into computer, powered up device (required sequence) and my computer recognized USB mass storage in attached. HDD does power-up to the point I can feel the platter(s) spinning. But "My Computer ", nor "Disk Management" see's drive. With everything attached and running I re-booted computer, USB device recognized/mass storage, again nothing.
Any suggestions / conclusions ??

 

Figured it out. Above sequence wrong ... must first power up the drive, THEN plug into USB port. Works fine, recognized as a "Local Drive ".
Grrrr , but got it working. Sister-in-law will be happy.
