Well, I'm afraid that datasheet has me completely lost. I know pretty much nothing about reading this stuff, but here's the various bar codes/ID strings on the drive:

L1 B3B 192222

FRU PN 92F0428

EC895987

PN45G9490

E150455 LR34074 R9371775

SN 13 192222 S3

ESP2242411 FSP45G9883

EC 895964 4.0

Type 0662

Does any of this clear anything up?
