The possibility of serious reliability problems with certain of IBM's GXP-series hard drives has been well documented. High failure rates may have forced IBM's decision to sell its hard drive business to Hitachi, and anecdotal evidence has been overwhelming, spawning a massive thread that will not die here at TR, as over a thousand posts have rolled in over time detailing users' experiences with drive failures, failures of replacement drives, and struggles to get IBM to honor its warranties. The fiasco led to the filing of a class-action lawsuit against IBM on behalf of GXP failure victims. However, IBM has consistently denied unusually high failure rates on its GXP drives.
