Fernando Zuniga Posted April 30, 2020 Share Posted April 30, 2020 Hi, Four drives have crash in my server at the same time. The drives are not responding, apparently the PCB board was burn on all drives. They all were connected from the same power adapter. Connected all four drives in different computers without proper response from BIOS Trying to restart array, replace hdd, recover as much information as possible and wanted help moving forward. Thanks, Fernando Quote Link to comment
itimpi Posted April 30, 2020 Share Posted April 30, 2020 That does not sound good It sounds as if those drives have had it unless you can get something done via specialist repair company. Sometimes the drives controller cards can be replaced to get at the data and there are sites that specialise in this. You have to decide whether it is worth going that route, and such a decision will probably depend on the importance of the data on the drives and whether you have good backups. What type of power adapter were you using? There have been reports of the type that have the wires moulded in being prone to shorting and causing the type of damage you mention (or even catching fire in worst cases). You can get the remaining drives back into operation by using Tools >> New Config (I suggest you use the option to retain all current assignments); return to the Main tab and unassign the burnt out drives; make any other changes (e.g. re-order drives or add new ones) and then start the array to build parity based on the new drive assignments. Unraid will recognise any drives that have previously been used by Unraid and leave their data intact. Quote Link to comment

Fernando Zuniga Posted April 30, 2020 Author Share Posted April 30, 2020 Is there an option to replace one drive and have the data rebuilt Quote Link to comment
trurl Posted April 30, 2020 Share Posted April 30, 2020 Rebuilding a disk requires all the other disks. Parity is just a bit that allows a missing bit to be calculated from all the other bits. Without the other disks there is no way to rebuild. Quote Link to comment
