QNAP 5 bay NAS Data Recovery
Data successfully recovered from QNAP 5 bay drive system with AMD sticker, where software had reset or failed to update. Zero Alpha has successfully demonstrated data recovery for a problem 5 bay nas system.
This QNAP uses propreitory multiple disk admin and lvm2 raid software. Which will show as a volume group in common raid software but with no filesystem detected. You will not find a linux, ext3/4 or zfs system due to this complex structure. If you try to scan the disk virtually you will only find raw results with most files below block size. LVM2 THICK VOLUME will require thin-provisioning-tools installed. Thick provision (lazy or eager) never fluctates in size.
This device was checked and found to have no initiased qnap software and had possibly failed due to an update or technician interference. Direct lan cable connection found the device with qnap software tool. Most qnap systems will have a different subnet address and will not be visible from a 3rd party switch.
