Hello, I am not sure if this should go into tech@ since I cannot work out a decent fix for this yet, but atactl secerase has a potentially dangerous 1000mS timeout set.
Potentially dangerous, because this timeout results in some misinformation being provided to the caller or user: # atactl wd1 secerase user User password: wd1 (pciide1:1:0): timeout type: ata c_bcount: 512 c_skip: 0 atactl: ATA command timed out wd1: flush cache command timeout # The HDD light remains solid ON for a long period of time, suggesting the erase is continuing despite the command returning early, with error. I was fortunate to be able to recover the current 160GB drive by using atactl secunlock and atactl secdisable. My 80GB test drive, as it seems, wasn't so lucky. I have found part of the problem in src/sbin/atactl/atactl.c in the device_sec_erase() function: ... req.command = ATA_SEC_ERASE_UNIT; req.timeout = 1000; req.flags = ATACMD_WRITE; req.databuf = (caddr_t)&pwd; req.datalen = sizeof(pwd); ... req.timeout = 1000; One problem is I don't know what this value should be, to provide no timeout. Given that a SECURITY ERASE UNIT command may not return until several minutes, or even hours, depending on how long the actual erase is, and given the potential to brick a drive, it seems that the timeout here does more harm than good. Running -current (cvs update performed 7/6/15; built 7/6/15). I have not modified any source files from the originals. This is a long-running regression; I have tested this back to 5.5-release, although in earlier releases, I noticed it seems to "cancel" the erase once the timeout is up.
