I'm cleaning house a bit. I have four IBM Model: WD-280 2.5" hard drives. The interface is not IDE nor SCSI. I once managed to Google up a page with an extensive listing of 2.5" drives (laptop service company?) which indicated that the interface was something else, the name of which I no longer remember. Anyway, I have no use for these. If you do, email me, pay shipping and they're yours. If I do not hear from anyone in one week I will dispose of them. Two of them are still factory sealed. A third one's bag is opened but the drive passes a non-electrical inspection. The fourth one has an ominous rattle coming from inside as if the head arm is swinging around loose. If you do not want the fourth one, I am happy to ship only three. Other markings on the drive include: P/N 06G6449 FRU P/N 95F4708 MLC C99714 I hope someone has a use for these unusual drives.
