Applications
The Quantum Bigfoot TX is one of the most recognizable hard drives from the mid-to-late 1990s, notable for its use of the 5.25" form factor at a time when the industry had largely standardized on 3.5" drives. Quantum introduced the Bigfoot line to deliver high capacities at low cost by using larger platters, making these drives attractive for budget desktop systems of the era — particularly consumer PCs running Windows 95, Windows 98, and MS-DOS. The 5.25" size requires a full-height 5.25" drive bay, which was common in mid-tower and full-tower cases of that period. Today, Bigfoot TX drives are sought by retrocomputing enthusiasts restoring period-correct 1990s desktop systems, as well as collectors who appreciate the distinctive oversized form factor. The IDE interface is compatible with any standard 40-pin PATA controller or motherboard IDE header from that era.
This Quantum Bigfoot TX 4.0AT 4GB 5.25" IDE hard drive has been wiped and formatted and boots to a waiting C:/ prompt. We have tested multiple units from this stock and all are model 4.0AT; the unit shipped may carry part number TX04A011 or TX04A109 but is functionally identical in either case. The drive shows typical light wear consistent with previous use. Please view our photo set and contact us if you have any questions.
