I was replacing a dead Seagate ST238R over this weekend, and I have hit a stumbling block that I'd like a "sanity check" from you folks. System Config XT clone (w/turbo) 1 floppy Adaptec 2070A RLL Controller ST238R 30 Mb (former D: drive) ST277R 60Mb (new drive), mapped into two "logical drives" MS-Dos 3.2 Since I am running DOS 3.2, after doing a low level format of the entire 60 Mb on the new 277R, I found out that FDISK couldn't "reach" the cylinders above 432. I then re-LL-formatted, specifying that I wanted two logical drives to reside on the one physical device. I was then able to FDISK and high-level format both logical drives. I was also able to read and write to both of them, as well. The problem came when I was trying to bring the older ST238R (not the dead one, but it's "brother") on-line. Upon power up, I see the drive access LEDs being activated on both drives, however whenever I try to access the older drive, I get "Invalid drive spec." Trouble shooting: First, I ascertained that I had removed the intervening terminating resistor and had set the 238 as the second drive. I swapped the 20-pin cables, on both ends. (The Adaptec requires the first drive to be cabled to J0 on the controller.) I took the 277R off-line, put the J0 cable into the 238, changed the jumper to be the first drive. This allowed me to boot a diskette and talk to the C: drive, showing all of my data intact ... relieving my sweat deficit IMMENSELY! I put "lastdrive=f" into an otherwise empty CONFIG.SYS, with no additional success. ================================================================ Can anyone explain what I may have overlooked, and/or a solution to my problem?
