Question 1

I don't know if it fit's in my toshiba satellite?

Accepted Answer

Based on the several laptop hard drives (typically 2.5" wide) I have grave doubts that this 3.5" wide drive would fit in any laptop that I have serviced.

If your Toshiba laptop has a new Solid State hard drive (SSHD) which are even smaller I have even more doubt that this 3.5" drive would fit.

I have about 6 or 8 of these 3.5" drives, all in desktop computers.

Question 2

WD5000AAKX: What different about the "-FR" models vs non "-FR" ones?

Accepted Answer

FR is used by WD on some  models for "Refurbished"
I find  "Refurbished"  HD work fine. You can find bad sectors on any HD, so run CHKDSK.
