Ah sh!t!... erm... press on.

If you are reconfiguring a RAID, or whatever other storage system, and something unexpected happens, or something happens that you do not fully understand, stop.

Pressing on in this situation would likely make things worse. Pressing on for long enough will eventually make things irreversibly bad.

This thread on Tom's presents a good example. When reading it, keep in mind two things,

  • Even if one do not initialize the RAID, each time RAID 10 is reassembled and resynched with different order of disks, there is a 50:50 chance of total data loss

  • Repairing a filesystem or troubleshooting boot process without having fixed an underlying RAID first is certainly useless and often damages the data.

QNAP Data Recovery

We were doing some experiments with our QNAP TS-639: pulled off six drives storing several real shares total capacity of 7.5 TB, inserted new blank drives and created a new RAID5 over them, made new test shares, loaded the data to them, and turned off the system. When we put the old disks (with real shares) to the corresponding bays and turned on the unit, the system has booted without a problem but…our Windows 7 PC could no longer see the NAS. QFinder 6.2.0.0726 saw the NAS and reported that the QNAP had an IP address. More than that, all the shares were available in the Control panel of QFinder.   Went to the General setting in QFinder and everything looked good in there: Tried to map a network drive as described here and got the following: " Network failure: the device was not found on the network. Please check the device status. " In Windows Network we had the following: Clicked the NAS from the...

APFS Data Recovery

By -
Apple File System, APFS for short, is a brand-new filesystem released in 2017. The goal is to replace HFS+ which has been in use on Apple computers since 1998. Formally released in late 2017, APFS filesystem began to be used by default on Apple computers running under MacOS High Sierra. Among the main features of APFS filesystem are 64-bit pointers allowing to address 2^56 blocks More accurate created/accesses/modification time measured in nanoseconds since 1970-01-01 Copy-on-write Sharing blocks between APFS volumes Native full-disk encryption We are happy to announce that now ReclaiMe data recovery software is capable of recovering data from APFS-formatted devices be it a USB thumb drive, or external hard drive, or internal SSD boot drive. You can download the latest build of ReclaiMe at www.ReclaiMe.com .
