![]() ![]() It just complained about the 'cylinders'. I even resorted to PuTTY and connected to the Linux installation and tried FDISK on /dev/sda (in an attempt to wipe the disk completely). I have also followed all the suggestions about mounting the drive in a Windows 7 PC and using the CLEAN command and/or formatting as MBR - that did not fix this issue either. This dose not fill me with confidence going forward, as this would be completely unacceptable in the future with 9TB's of data - swapping disks would completely trash the data. This appears to have got me past the problem, as now Bay 1 is reporting as OK, but Bay 4 (the original HDD1) needed formatting! Last resort was to power off the QNAP, remove all the disks (swap them round) then use Finder and run throught the config process, as described above. I have also tried a 320Gb disk in Bay 1 and that also will not format in Bay 1. I have formatted a disk on bay 2 and swapped it to bay 1, but it is still unreadable - long term this is no good anyway with a RAID 5 array (as the data would get destroyed). ![]() Although with all the reports of 3.6.1 slowing performance, I am tempted to stick with 3.5.3 (thoughts?) I have tried last four firmware versions: 3.4.4 / 3.5.3 / 3.6.0 / 3.6.1 and they all report the same problem. I have no problem with Bays 2,3 or 4 - the 3TB disks have gone in and formatted fine. HDD Bay 1 would not format the QNAP kept reporting the drive as Formatting failed(Cannot unmount disk). I have just bought a QNAP 412 Turbo NAS and installed 4 x Hitachi 3Tb HDS5C3030ALA630 - my issue has been very similar. If anyone could point me in the right direction I'd be very appreciative (as you can probably imagine). I've looked through these forums + general google search but haven't found anything relevant. Format disk 1 - Formatting failed(Cannot unmount disk).Īnd that's about the point that I thought I needed some kind of help Have you ever tried to format a disk in Mac OS X and Disk Utility won't Unmount the Hard Drive for formatting It can happen for external (USB and Firewire) as well as internal disks. It creates the raid array and starts formatting then I get the error 'Formatting failed(Cannot unmount disk)'.Ĥth Step - after a few 3rd steps, I decided to format both hard drives independantly - 2nd drive formats fine and 1st disk : Formatting failed(Cannot unmount disk).ĥth Step - swap the drives (phyiscally) and the problem seemed to follow the drive.Ħth Step - 'scan' the drive + check with smart - nothing wrong.ħth Step - remove the drive and put into a linux box, completely remove all partitions and format drive - all good.Ĩth Step - put back into qnap (slot 1) and format (single disk) - ' Formatting failed(Cannot unmount disk).'ĩth Step - de-grade qnap back to version I initially set up everything as. About a week ago I took some time to fix the problem: The RAID array was degraded - disk 1 was marked as uninitialized.Ģnd Step - I tried to repair the array (no luck).ģrd Step - decided it'd be quicker just to restart from scratch, so removed the array and added a new one. ![]() I originally purchased the system at the beginning of the year and have had trouble free motoring up until about a month ago (little red light flashing). It has 2 x 2T seagate drives configured in raid 1 configuration. I have a TS-219P running the latest firmware. ![]()
