Bad capacitors are causing issues for countless technological items built throughout the last century and into the early-mid 2000’s. Unfortunately, hard drives aren’t spared from this tragic scenario.
Below are a few examples of this particular issue, plaguing Toshiba hard drives from the early 90’s in particular.
Capacitor leakage on the majority of these drives has caused major issues, resulting in a necessity for advanced trace repair & circuit analysis. As a result, Toshiba hard drives from this period are particularly susceptible to demonstrating strange behaviour, failing to start or simply refusing to identify. All drives above required full capacitor replacements in order to function as expected.
A full list of (currently) known models impacted by capacitor leakage can be found below. This is followed up with another list of models known not to be affected.
All Toshiba models produced past 1996 are not affected.
============================================== TOSHIBA: IMPACTED MODELS BY CAPACITOR LEAKAGE: ============================================== - MK232F/MK234F - MK1032F/MK1034F - MK1122F Note: Identifiers - MK1422F past F (e.g. B (SCSI), C (IDE)) - MK1522F all suffer from the - MK2024F same issue. - MK2124F - MK2224F - MK2326F - MK2428F* - MK2526F/MK2528F* ============================================== TOSHIBA: NON-IMPACTED MODELS: ============================================== - MK1624F - MK1722F/MK1724F - MK1822F/MK1824F - MK1923F/MK1924F/MK1926F - MK2720F ============================================== *unconfirmed entry, although PCB design seems identical to 12.5mm variants (e.g. MK1422F)
This post will be updated over time, as model confirmation continues to occur.
