I have a lenovo ix4-300d with 4 bays, each with a 2TB HDD in a RAID5. This evening it reported a data storage fault and auto-recovery email. Then a data protection reconstruction completed but with some potential data loss. When accessing the share it appeared as though half of the data that was present was missing from the share. I checked the interface and it showed an error with bay 1 that had a recoverable error. However, following a data integrity check and reboot the device came back online with only 1 drive showing data and prompting an overwrite of drive 3 which i didn't activate. I replaced the drive in bay 1 with a new 2TB HDD and rebooted to try and rebuild, suspecting it was drive 1 that had finally broken, again, prompted to overwrite but this time on drive 1 (the new replacement disk) i couldn't get the lenovo to overwrite the new disk 1, and was stuck in this state. Had to cold power down the box and replaced the original disk 1 back in the device. When the box was online, no shares were present at all, and the device was prompting an overwrite of the drive in bay 3 which i've ignored.
The automated errors sent on email state: "Storage failed and some data loss may have occurred. Multiple drives may have either failed or been removed from your storage system." At this point, decided to contact Data Clinic (http://www.dataclinic.co.uk/raid-data-recovery/). I'm happy to send the entire unit up to you and have a screen shot from this very morning with the size (2.32TB) and number of files (138,163) that should be across the 4 bays in the RAID5. Would appreciate an initial email on Monday rather than call back to advise of likely costs of review and data retrieval. Happy to send 2x 5TB external HDDs with the lenovo for backups.
We have an old windows 2003 server that we inherited from a merger and need to keep running for a legacy database. The server now won't boot. We suspect it to be a hardware fault but not entirely sure what at this stage. The RAID disks seem to be ok and the data intact as we can access it when we use a caddy attached to another computer. We cant get it to boot in another computer though and it just wants to run a windows repair and we don't have the administrator password. We basically need to get this disk booting into Windows again so that we can access the database. Again, this is another job for the RAID recovery experts at Data Clinic.
