Waterproof or not?

By Geek -

Roaming the web we stumbled upon a blog post that tells about new waterproof SD card technology. Naturally, we wondered whether such memory cards are really needed or may be ordinary cards are just enough. So we gathered memory cards which were at hand and also decided not to ignore a USB pen drive. We formatted and put files on all of them.
Then we filled a microwave container with water, put all the devices into it, and left them sit underwater for half an hour.

So we got (left to right)

  • Nikon EC8-CF 8MB CompactFlash
  • Transcend JetFlash V30 2GB (USB pen drive)
  • Sandisk M2 2GB
  • Kingston MMC mobile 1GB

under water



After that we got the devices out, wiped them dry and connected to the computer one by one.

And here is the result of our experiment: all of the memory cards work well with their content intact. As for the USB pen drive, we were concerned for a moment that we killed as we watched it sink slowly, filling up with water. However, in the end, the pen drive works perfectly as well.

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 .
