JP>Funny behaviour of a HD. I have this 30 g HD that was extracted
JP>from the Thinkpad and that now is in an external USB case. I tried to
JP>get it connected yesterday and it would go chunk-chunk-chunk but not
JP>be seen. I placed it back into the TP but it was not seen either and
JP>I could not Restore to it.

JP>Called IBM, they were willing to send me a new HD as it is an
JP>FRU but wanted me to run tests before. I was given a URL of
JP>www.HGST.com and to D/L from support the CD Image. It came down as
JP>an .iso file and I copied it as an image to a CD then ran the tests.
JP>The HD is good. Oh ! then I thought. I booted to DOS and ran the
JP>FDISK routine on it plus a format. Now it is seen.

JP>Now that you read the story, here is the question...what could
JP>have happend to this HD to loose it MBR and its format ? It was not
JP>dropped nor banged about. This is my first instance of this
JP>happening, have you lived this ?

That actually sounds more like a hardware issue. If the drive isn't seen by
the BIOS, it has nothing to do with MBRs, formats, etc.  The
"chunk-chunk-chunk" sounds more like the drive trying to seek track 0 than
trying to read a file system.

Maybe the shaking you gave it in moving it around caused the heads to misplace
and then get back into place.  If so, it's a time bomb waiting to happen.
Hopefully, it was more like a cable issue...
