Where is Pin #5 at?

Specs: Windows 95, 266/16
I got an older hard drive and trying to reinstall it long enough to remove an Autocad file. Per my good-bok and old data onna web, it says to attend to pin 5. In fliping my HD over, I can see only Jumper nos. 16 to 25 on the bottom. Where is this mysterious #5 at?


The HD I am working with is a Maxtor Model 7245AT and being used on a Win 98 computer.

245MB HDD? Wow! All you need to do is jumper it as either master or slave, then connect it to an IDE cable. When you boot up, it will be assigned a drive letter, then you'll be able to do whatever you want with it.

You asked about this drive over a year ago & mavis007 provided the info you needed. Apparently you never went back to that thread? The only jumper need to be concerned with is J20.

Mick...

I already tried as noted, but with zero luck. I got the case off, the drive is recogised via the BIOS and can feel what I think is spinning over. However, the Windows operation says the whole drive does not exist, and I cannot get to it via the DOS level either.

The smaller HD now has one file that used to be there, circa 2002, and have not used it in years.

Had some troubles with the posted diagram as of back when, for it did not match the underside of my drive exactly at that time.

I think there may have been more than one pc board for that drive but if it was working previously the only jumper you need to worry about would be J20--the master/slave setting. I don't think any of the others would affect its being seen.

If it was identified in its previous computer as a particular drive type and then moved to a different PC and defined differently then it's possible yoiu won't be able to find the data. So do you know how it was set up in its original computer?

Also, run fdisk, option 4 on it and post back what it says.

Wadda you mean run FDisk?


Doesn't this destroy most everything on the disk?

What computer did the drive come out off? In that era some systems did not autodetect the drive type. Different setting (CHS) could be used.

Well, if you use fdisk option 3 and remove the partitions then yeah, it's all gone. But option 4 is to view partition information.

Fred:

For quite some time it was used on a Windows 3.1 machine as the second drive. The P-S had enough poop to push it along. The original BIOS could auto detect or your could write in maually via their info reported. I still have a bunch of the orignal cables for this operation.

Then that computer got obsoleted out with a bigger and faster H-D inside another computer. Everything was for free as neighbor kept passing older models he got free from work on to me. 'cept for the software. Which he kept copies and key cards on.

I figured out the the pin #5 being referred to is same as JPT-20. Only five in a row on whole bottom of the drive.
