How to clear flash on the SG300-20

[meredith.mohr1]

I've got a Cisco SG300-20 that I am trying to wipe.  I've performed a factor default.  This clears out the configs, but not the flash.  On other Cisco devices I would use the "format" command, but the SG300 does not appear to have this option.  How do I go about clearing the flash (and any other data that isn't wiped during a factory reset)?

Device info:

SW Version: 1.3.0.62

Boot Version: 1.1.0.6

HW Version: V02

Hello,

you can use the DIR command to see what do you have in the flash then you can use the DELETE comman.

for example: switchxxxxxx# delete flash://backup-config

note: mirror-config, *.sys, *.prv, image-1 and image-2 files cannot be deleted.
