I have a multi-boot MBP retina;

(from linux mint 17.3 and last col. from windows diskpart):

tool        sudo blkid       gksudo gparted       windows 10 diskpart   Win10_GUI
/dev/sda1   EFI - vfat          EFI - fat32       fat32                 fat32
/dev/sda2   BOOTCAMP - ntfs     BOOTCAMP - ntfs   ntfs                  ntfs
/dev/sda3   DATA - hfs+         DATA - hfs+       ntfs                  raw
/dev/sda4   OSX - hfs+          OSX - hfs+        raw                   raw
/dev/sda5   Recovery - hfs+     Recovery - hfs+                         hfs+
/dev/sda6   swap                swap                                    raw
/dev/sda7   mint - ext4         mint - ext4                             ext3
/dev/sda8   swap                swap                                    raw

I disabled journaling btw

My question was which tool do I trust (I forgot long time ago how I formatted them) to tell which partition is of what type?

This came about because my windows 10 used to be able to read and write to my DATA partition (as did my others) but ever since I tried a trial version of Paragon, windows always wants me to format DATA (which it calls now D:) instead of opening it like I used to. It also is the same with E:\, which used to be able to be read and written to - it is where linux lives.

I remember I formatted everything using Mac software via Bootcamp, so Mac (and via Bootcamp drivers) and Windows could work with them. I then installed Win10 & lastly Mint and so it seems that these changes weren't reflected by Mac or Win10 and so it could still access them. I'm guessing the bootcamp drivers were why I could access my shared partition (hfs+)

I just installed a trial version of MacDisk 10 and now the labels I used on the partitions when they were created are back - so it seems to me that Paragon wasn't that great... or it initially "killed" my bootcamp drivers?

Any thoughts would be greatly appreciated. Though I suppose I'll just drop $50 for macdrive...

But my real question is if there is an easy way to get my bootcamp drivers to again read/write to my shared partition DATA. DATA was originally partitioned in mac to be hfs+, but then changed to something else - I can't remember, nor figure out from these terminal commands. All I know is I could read/write to it via all three OSs.

Hope this was clear...

update Regarding first comment...

  • Is it possible that you have hybrid GPT and ms-dos partitioning on that drive. What do gdisk -l /dev/sda and fdisk -lu /dev/sda say? – Stéphane Chazelas Aug 8 '16 at 19:38
  • I guess so... I read a little about gdisk vs. gparted and I am thinking that the former is a better option. So I guess I should trust gdisk over all others? – nate Aug 8 '16 at 20:04
  • Wjat does file -ks /dev/sda3 say? – Stéphane Chazelas Aug 8 '16 at 20:11
  • I added the above edit... – nate Aug 8 '16 at 20:15
  • I don't see a difference between gparted and blkid... – John Leuenhagen Aug 9 '16 at 1:55
