I have some questions about your PC hardware.
1. After disabling the CPU cache, can you format a floppy using LIFUTIL?
2. Read Test. With a floppy formatted on a 9114, can you run fdio -info?
3. Write Test. Can you write a LIF image from the ftp archive using fdio?
4. What are the results of running testfdc?

Hello Dave,

Unfortunately I can't disable the cache (in the BIOS Setup, maybe there are tools to accomplish that, I don't know). The laptop I use is a Pentium 4 2.0 GHz, much too modern probably, but some images could be restored.

1. Although cache was active, formatting a disk using LIFUTIL was successful.
Verified also using an HP 71b / 9114.

2. Also looks good.
FDIO reports: "Medium in drive a: looks like LIF 3.5 DS/DD (616 kBytes)".
Sector size 256, Data rate 250 kBytes/s, Cyl/Heads/Sectors: 77/2/16.

3.
No problem. I wrote lexfl1.lif to a disk, and 9114/HP 71b could read the files.

4.
TESTDFC 1.18, testing 720k DD, reports:
BIOS reports drive A: as 1.44M HD, 80-track.
Single Density at 250 kbps: passed
Double Density at 250 kbps: passed
Double Density at 250 kbps / 128 byte sectors: failed.
(300 and 500 kbps: not tested )

Altogether, from these tests my system seems to be not that bad ...
It would seem that I can't restore those TD0 images that originally were recorded from SINGLE sided disks, by the way.

Thank you again for advice and assistance!
Michael
