Quicker fixes are not a good idea (in most cases)

By -
Every once in a while someone comes up with a forum question along the lines of

I have such and such problem with my storage. The data is still accessible, but the storage unit is for some reason in abnormal state. What should I do?

Typical (and proper) answer is
  1. back up data,
  2. test the backup,
  3. make sure the original problem, which caused whatever abnormality there was, is corrected,
  4. rebuild the storage from scratch,
  5. restore data
Often, this is not considered a good enough advice: Is there any quicker way to resolve the issue?

Actually, no. To make sure the abnormal state is properly repaired, one needs to identify all the undesired effects and changes to the data. This is plain impossible in all but most simple cases. So, there is always a risk of missing some important point during "quick" repair, masking the problem instead of repairing it. The issue might then reappear later in some undesired way.

QNAP revisited

By Geek -
For reference, we were using QNAP TS-639 Pro with six WD20EADS disks. After about half a year of use, the web-interface was running slower, so that we needed to wait for several minutes to obtain the list of the disks. Gradually, we noted that the array performance decreased significantly. It seemed obvious to assume that one of the member disks has been dropped from the array and a RAID5 was working in the degraded mode. However, all the member disks were marked as GOOD in the web-interface. It was suspicious that LEDs on the disk bays indicating the state and activity of the disks were blinking unevenly. Logically, for RAID5 one should expect almost symmetric load on the disks, but in fact, one of the disk LED was blinking much more frequently. Once we had run the bad blocks check on this disk through the web-interface, the disk dropped from the array in less than half an hour and its bay LED turned red. At this point, the web-interface began to work properly again. The disk taken fr

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 .
