Cause<\/h2>\n
Error 0x3 means ERROR_PATH_NOT_FOUND (Path not found). This can happen if the Reagentc tool does not detect the recovery partition, and the root cause is incorrect attributes assigned to it.<\/p>\n
The Diskpart’s “detail partition” shows that the recovery partition has incorrect attributes.<\/p>\n
Partition 5\nType    : de94bba4-06d1-4d40-a16a-bfd50179d6ac\nHidden  : Yes\nRequired: Yes\nAttrib  : 0XC000000000000001\nOffset in Bytes: 511323406336\n\n  Volume ###  Ltr  Label        Fs     Type        Size     Status     Info\n  ----------  ---  -----------  -----  ----------  -------  ---------  --------\n* Volume 3         Recovery     NTFS   Partition    749 MB  Healthy    Hidden\n<\/pre>\n
\"reagent<\/p>\n
The attributes value of 0XC000000000000001<\/strong><\/code> means the following bit has been enabled that causes the partition to be hidden:<\/p>\n
0x4000000000000000 – Hides a partition’s volume so it’s not detected by the mount manager.<\/strong><\/p>\n

RELATED:<\/strong> REAGENTC.EXE: Operation failed: 2<\/a><\/div>\n
Resolution<\/h2>\n
To resolve the REAGENT error 0x3, fix the GPT attributes value for the recovery partition.<\/p>\n
The recovery partition is located on Disk 0 and Partition 5 <\/strong>in this example<\/strong>. Please see the above screenshot.<\/p>\n
In that case, please run these commands from an admin Command Prompt:<\/p>\n
diskpart\n\nselect disk 0\n\nselect part 5\n\ngpt attributes=0x8000000000000001\n\nexit<\/pre>\n
\"reagent<\/p>\n
Now, run the following command:<\/p>\n
reagentc \/info<\/pre>\n
\"reagent<\/p>\n
That fixes the issue.<\/p>\n
