I have tried to install RH9 several times. This machine has been running RH8.0 just fine. I tried to install RH9 as a fresh install and have it check for bad blocks on each file system. It is a Dell Computer with a Maxtor 30Gig IDE disk. When it failed I did the crtl+alt+d to test the disk and it passed. So then I loaded their diagnostics and ran it and it passed. So then I did an install and just selected MIN install and had it check for bad blocks and it worked. So then I tried again and selected what I really wanted and it failed. So then I got a copy of a crash recovery cd RH8.0 and ran badblock -svw /dev/hda and it passed. The question I have is what command is run when you select ext3 and check for bad blocks? I was looking at the man page for mke2fs and it says: -c Check the device for bad blocks before creating the file system. If this option is specified twice, then a slower, destructive, read-write test is used instead of a fast read-only test. So is RH9 doing -c or -c -c? Or is it using some other command? Thanks!
