I'm looking to purchase a WDXT-GEN F340(F300 seems to be more common) because I want to use a Seagate ST-251-1 in an IBM 5150. According to the documentation F340 is the model number I need for that drive.
However, the F300 version of the card is a 'dynamic' type of controller (see [here]). With the F300, you inform the low-level formatting code of the geometry of the attached hard drive. Down the track, should your ST-251-1 fail, the F300 would allow you to choose a replacement from a wide range of 'MFM' drives (rather than being restricted to another ST-251-1, or equivalent).I'm looking to purchase a WDXT-GEN F340(F300 seems to be more common) because I want to use a Seagate ST-251-1 in an IBM 5150.

In regard to fitting hard drives into an IBM 5150, in case you are not already aware, be aware of the information at [here]. The +12V rail in the IBM 5150's 63W power supply is rated at 24W. According to the Seagate document at [here], the +12V start-up power requirement of the ST-251-1 is 30W (12V @ 2.5A). Maybe the IBM 63W power supply can absorb a temporary additional 6W at start-up.... because I want to use a Seagate ST-251-1 in an IBM 5150.
Yeah. If I can get the mfm drive to work in the 5150 I'll put an xt-ide with a dom in the 5162is this the same ST-251 you were trying to get working on the 5162?
