Hi: I've recently successfully configured an external USB hard drive, Prolific Technology Inc. ATAPI-4 Bridge Controller, rev 1.00/1.00, addr 2: uplata0 (v1) da0 at uplata-sim0 bus 0 target 0 lun 0 da0: <TOSHIBA MK6411MAT > Fixed Direct Access SCSI-0 device da0: 900KB/s transfers da0: 6194MB (12685680 512 byte sectors: 0H 0S/T 0C) using a kernel module kindly provided by Ian Dowse (iedowse@maths.tcd.ie), http://www.maths.tcd.ie/~iedowse/FreeBSD/uplata.tgz FYI, I recently purchased the enclosure from Computer Geeks (www.compgeeks.com) for $21, then added a Toshiba 2.5" laptop HD. (I'm running FreeBSD-4.5-STABLE, built 5 April 02.) Does anyone have recommendations for exercising the filesystem? (For stability testing.) I'm currently using 'iozone' (/usr/ports/benchmarks/iozone): iozone -az -i 0 -i 1 -R which should take several days at 50-150KB/s (!) I've completed testing with the msdos filesystem. Now, I'm running ufs+softupdates. What I'd really like is a utility which creates/deletes lots of files and directories, while repeatedly traversing the directory tree. Thanks for any help or pointers. --Bill To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
