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, 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.
