I asked this earlier in this list, but no one answered so I assume, that no one got this message. Can anyone tell me why the mtools are getting slowly when I write to SCSI disks instead of IDE disks ? At home I have a SCSI disk partitioned in FreeBSD/DOS partitions and when I'm using mcopy to write onto the DOS partition I get a rate of nearly 2KB/s. Even a mdir command acts very slow, sometimes the whole system freezes for maybe 15-25 seconds. At work I have a Toshiba laptop with an IDE disk (also 1 DOS and 1 FreeBSD partition on it). When I'm writing to the DOS partition with mcopy it's really fast (I think nearly 1 MB/s). An mdir is also very fast. So what can I do ? Is it a SCSI-problem ? I have an Adaptec 2940AU and all of my disks act the same...:-( Maybe there's a fix for the SCSI subsystem ? By the way: I'm using FreeBSD 2.1.6R, maybe I should update ? Anyway, I got these problems since the first use of the mtools in 2.1 for using them to write to DOS partitions. By the way, I'm only using the msdosfs when reading DOS files. I trashed my disk too often after writing to it, so I have to use the mtools because they're working perfectly. They are just damn slow...:-( Thanx for any help !
