Hi,
I'm trying to connect an old disk from a Sun-3 to a PC running Linux (99.11).
The disk is an Emulex MD21 307 Mb. I'm a little confused about the type
of the disk. I always thought it was a SCSI, but my ADAPTEC 1542C says
ESDI. It recognises the disk and I can format, and verify it. The real
disk geometry is: cyl 896, hd 14, alt 3, sec 50. The 1542c seems to map
this to: cyl 307, hd 64, sec 32.
When I boot Linux, it recognises the disk, but somehow it sees it twice. I do
have /dev/sda and can make a partition table, but when I try to write
that partition table I get some error messages. But the next time I boot, the
newly created partition table is correctly found. When I try to make a
filesystem on the disk I get the following error message:
SCSI host 0 timed out - aborting command
I saw some messages about possible problems with the Linux Adaptec 1542c
driver.
- Might this be an occurance of the same problem?
- Does anyone know whether it is possible at all to connect such an old
disk to a 1542c and make it really work?
