NEW OEM Original Genuine Apple Macbook Pro 13" A1278 2009 2010 HDD Hard Drive Cable 821-0814-A
Factory service part for Macbook Pro 2009 and 2010.  Original part 821-0814-A.Note: this will also work in Macbook Pro 13" from 2011, but cable length will be slightly longer than necessary - so it will "bunch up" inside system.  100% compatible, but it may appear unusual.Installation notes: take care to disconnect your battery and power supply, and deplete any residual power from your system prior to installation, to avoid damaging the new cable.  HDD Cable carries power whenever battery is connected!!
