The unit stop responding about 5 days ago. The unit it a Dell PowerVault 715n NAS. The consist of 4 120 GB Western Digital IDE Drives configured in a software RAID 5. I ran the units internal Diagnostics and it passed all tests. The unit has no Video, CD ROM, Floppy so it's kinda hard to trouble shoot. I can however access the unit in a pre boot stage via serial using a null modem cable. I called Dell on Friday and spent a couple hours trying swapping the drives around with no success. Does any body know anything I can try on this unit? or away I can break the RAID so I can put the Drives in my external USB drive cage and read the data? Thank you for your help.
