I've been a tickled pink user of FreeBSD for several years now. However, I've been having some trouble and I don't want to submit a bug report if the answer is that I simply don't understand. I'm having trouble using some 37.5gb IDE disks under 3.3. I talked to a Linux using friend who pointed out that Linux has had a bug in its IDE driver for disks larger than 32gb. I spent a few minutes going through the 3.3 source and found what seems to me to be a similar limitation. In the file wd.c at line 861 the Logical Block Address translation appears to limit the number to 28 bits by ANDing off the top 4 bits of the 'head' value. (I hate using 'head' since this is dealing with the IDE kludge called LBA but you can see what I mean.) My math says that 2**28 sectors of 2**9 bytes equals a total of 2**(28+9)=2**37= 128 gigabytes so there shouldn't be a problem but still a similar limitation. I'm very sorry to bother you about this, but could you please tell me whether 3.3 should be able to talk to my 37gb IDE disks? Every time I run newfs on them to create a huge filesystem things work great until I attempt to do anything to the filesystem. Then the system simply panics with a "corrupt Inode" message. I submitted a bug for this on Vinum (I was originally trying to span 4 of these monster disks with Vinum). I now suspect that the problem is more basic.
