I don't know if this is a problem specific to CURRENT or not, but bcwipe seems to do the right thing when wiping files. however, when using the -b option to wipe an entire block device, there is an "Invalid Argument" error, and I don't understand exactly why... fbsd52# bcwipe -bvmd /dev/da0 Wipe /dev/da0 (y/[n]/a)?a Wiping device /dev/da0 Writing to /dev/da0: Invalid argument fbsd52# bcwipe -bvm3 /dev/fd0 Wipe /dev/fd0 (y/[n]/a)?a Wiping device /dev/fd0 Writing to /dev/fd0: Invalid argument fbsd52# these are examples of commands verbatim from the bcwipe man page... The devices exist in /dev/, and there is a floppy in the drive... This is the dmesg for the USB hard disk that I'm ultimately trying to wipe... umass0: Cypress Semiconductor USB2.0 Storage Device, rev 2.00/0.01, addr 2 umass0: Get Max Lun not supported (STALLED) GEOM: create disk da0 dp=0xc2060450 da0 at umass-sim0 bus 0 target 0 lun 0 da0: <WDC WD12 00JB-00FUA0 \\0000\\0000> Fixed Direct Access SCSI-0 device da0: 1.000MB/s transfers da0: 114473MB (234441648 512 byte sectors: 255H 63S/T 14593C)
