thepregnantgod Posted December 21, 2017 Share Posted December 21, 2017 I don't think this is a product of Drivepool. But I know many of you guys are storage fanatics and might have faced this before... I am routinely finding a drive that loses its partition and goes RAW. This is a huge pain that I'd like to remedy. 1. What, in your experience, can cause this? 2. What is the easiest way to rebuild the partition and have the drive be good again? 3.

0 Christopher (Drashna) Posted December 21, 2017 Share Posted December 21, 2017 This can happen any time a write to the disk is "interrupted" while writing to the partition table. USB for instance, can do this, frequently. CHKDSK. No, really. In many cases, a CHKDSK pass can fix the damage and restore the partition to working order. However, normal data recovery should work too. TestDisk Recuva, EaseUS and other tools have the ability to repair damaged partitions. ReFS uses 'copy on write', so it may reduce the likelihood that this will occur. However, "fixing" may be much more problem, as not as many tools work on ReFS, at this point Additionally, converting the MBR drives to GPT would help too.

Maybe this explains why I've never seen this issue on USB drives: they're pretty much all formatted GPT. These days, I basically don't bother with MBR.

0 Christopher (Drashna) Posted December 23, 2017 Share Posted December 23, 2017 Yup. it stores the partition data twice. At the beginning of the disk (as normal) and a copy at the end. This greatly reduces the odds of this happening. It's still possible, but it may/should help. Quote Link to comment Share on other sites More sharing options...
0 thepregnantgod Posted December 29, 2017 Author Share Posted December 29, 2017 Thanks. I'm chalking it up to my horrible fascination with new tech and converting drives to ReFS. Since all my drives are above 2TB, now formatted as NTFS with GPT. I'm hoping this problem will go away. Quote Link to comment Share on other sites More sharing options...
0 Christopher (Drashna) Posted December 30, 2017 Share Posted December 30, 2017 Hopefully, it will. If not, then let us know, and if there seems to be any specific trigger. Quote Link to comment Share on other sites More sharing options...
