I have two cell phones Note2 and Honor 6. Both are rooted, and run 4.4.2 Both have a battery of same capacity 3100mAh. I can connect any of two external hard drives WD passport and WD Elements of 1 TB capacity (both are NTFS formatted and do not have provision for external powering on) through OTG cable on Honor 6 and transfer files But when I connect to Note2 through same OTG cable, the external hard drive LED flickers and can't view the contents of either drive.

Changing OTG cables, using multiple apps from play store to manage OTG mounting did not change anything

I read on some forum that note 2 battery capacity is not enough to power on the external hard drive for normal operations and is just enough to recognize the drive, hence the flickering. This was not substantiated by any technical explanation. Besides, Honor 6 also has the same battery capacity!!! So this explanation doesn't sound logical unless am missing something

Would welcome a technical explanation for this please

Edit: situation is the same if the external drive is formatted in FAT32


  • Most likely it's the file system being used. NTFS support rarely is available on Android devices. To verify that, you could create another partition on that drive using a supported file system, such as FAT32 or EXT3, put some files on it, and try if those are seen. – Izzy Nov 3 '15 at 12:49
  • Honor 6 have 3 GB RAM, But Note2 have only 2 GB RAM – Tintumon M Nov 3 '15 at 12:50
  • Thanks @izzy . Should have clarified this in the question. I have yet another drive formatted on FAT32 and even that is not recognised. BTW are you suggesting that honor 6 has the added capability to read NTFS? Purely my opinion, without any technical backing but Huawei phones aren't really that inclusive – beeshyams Nov 3 '15 at 12:55

    @TintuMon thanks. Agreed. Does RAM play a role in this? Would like to know more – beeshyams Nov 3 '15 at 13:00
  • Well, if the drive is formatted using NTFS, and the Honor can read it – isn't that the logic conclusion? If it would not support NTFS, it were not able to. So either the drive doesn't use NTFS, or the Honor supports it, or you're seeing ghosts. Your choice :) – Izzy Nov 3 '15 at 13:14
