既然部落格文章是拿來自爽用的..那看到人家牆壁上掛了那麼多奇怪的"死人骨頭".
當然要把一些自認很寶貝的東西拿出來"敝帚自珍"一下...
希望有一天能像謝仔買的那台相機變的這麼值錢
我只記的家中第一台的三八六電腦用的是CONNER 40MB的硬碟.
令人訝異的是後來這幾顆從資源回收場撿來的硬碟大約是1992年.
也就是說當桌上型電腦還在用三吋半這種小硬碟時.
這些可能用在高階電腦用的硬碟竟然已經用所謂五又四分之一吋的全高硬碟..
介面有narrow-SCSI 和ESDI介面..整顆重量超過兩公斤.
而且這些資料還可以在網路上用文字檔的形式繼續留存
相信有點經驗的人對這些MTBF 耗電瓦數 硬碟轉速.搜尋時間的說明都有些認識.
就不一一說明
PS:目前還沒有勇氣把他接電測試看看.畢竟能轉動跟能正常工作是有差異的.
除非只是想聽聽古早馬達的轉動聲音
PS2.這兩顆希捷SEAGATE的硬碟一顆是美國製的(奧克拉荷馬).上面還貼有出廠的壞磁區列表.另一顆是新加坡製的
