The standard advertised capacity for the relevant model is 80–90 GB (often listed as 80 GB or 90 GB decimal), but the formatted/actual usable capacity frequently shows as 92.6 GB (or very close, like 92. something GB) in many tools, BIOS readings, or low-level utilities due to how the drive reports LBA sectors and binary vs. decimal conversion quirks. Some variants of this model were non-short-stroked versions that achieved higher formatted capacity on the same hardware.

Here are the key specifications for the Deskstar 180GXP (focusing on the ~90–92.6 GB variant, typically model IC35L090AVV207-0 or IC35L090AVV207-1):
