    Hey all,

    I am looking for a tool to help make wiping machines faster. SAS or SATA SSDs would be the primary targets and DBAN seems like it does not work for this.

    Ideally it would be a bootable ISO format so it can be mounted via IPMI.

    Does anyone else have a good recommendation?

    I switched from dban to nwipe a while back - basically the same thing (technically a fork) but it runs under linux instead of booting directly into it which gives it hardware support for everything that linux supports.

    But for SSDs the thing to do would be just issue the secure-erase command to them and let them do it internally. Any kind of external secure erase (eg. dban, nwipe, etc.) can't guarantee that ever block was overwritten due to the drives internal block remapping/wear-leveling.

    nwipe is included in the parted-magic bootable iso's (including the old free release thats still hosted in various places), as well as hdparm which can be used to issue the ATA secure-erase command.

    Most SSD vendors have utilities which can handle it for their drives.

    @TuxDude thanks. I bought parted magic in September so I may try that next.

    I just need something that can also deal with a "frozen" SSD. In terms of scale, not huge for numbers of drives, but if I am going to do something 20 times a week potentially, it would be easier to just mount an ISO via IPMI and let the thing roll.

    @cheezehead unfortunately, given the variety of vendor gear we get it needs to be a universal solution.

    I've never had any issues just doing a secure erase with hdparm, plus you can set OP with it at the same time.

    I have had bad experience with HDPARM OP mechanism.
    For some reason the change is permanent on some SSD. I tried to OP vertex 4 ssd that I had from 240gb to 100gb and accidently left out a zero in the block size and now I got a 10Gb SSD that I cant revert back to original size.

    Sorry to hear about Hdparm for your SSD. I would feel like I lost big time. I love my drives! Wish there was a software we could recommend to get it back for you!

    Patrick, I use Parted Magic in Windows. Works ok for me when I need to secure erase a SSD every now and again. You could also try Darik's tool. Seems bootable, but I am not sure how long/fast it runs. See here:

    2015: How to securely erase hard drives (HDDs) and solid state drives (SSDs) | ZDNet

    Article/page is dated for last year, but may help alittle. They also link to some other bits of software they recommend for secure erasing.

    Never had a problem with hdparm.
    Used it more times then i can count on samsung/pro , intel,adata and some others secure erase and OP.
    it is pretty important you follow the right path and steps otherwise you might end up with a bricked device.
    Method i use and prefer is thomass krenn method
