当我删除由我的Galaxy S3格式化的SD卡,并将其放在MacBook中, fdisk
显示其唯一分区,与具有分区ID 0C
表示它是FAT32 LBA分区。但是,OSX无法安装它,并且Ubuntu似乎将其安装为exfat分区。
此分区上使用的文件系统是什么?可以在分区ID和分区上使用的文件系统之间的差异阻止OSX安装分区?

When I remove the SD Card that was formatted by my Galaxy S3 from it and put it in a MacBook, fdisk
shows its sole partition as having partition ID 0C
, indicating that it is a Fat32 LBA partition. However, OSX is unable to mount it, and Ubuntu appears to be mounting it as an exFAT partition.
What is the filesystem used on this partition? Could a discrepancy between the partition ID and the filesystem used on the partition be preventing OSX from mounting the partition?
原因是,至少使用大于32GB的三星设备和卡片,三星或Android使用exfat文件系统格式化卡,但错误地将分区类型标识为"FAT32(LBA)" 或分区类型"C" 或卡分区表中的"0C" 。
如果使用Windows或Android分区应用程序使用exfat格式化卡,它将在MicroSD分区表中正确地将分区类型为7或"07" 或"exfat" (hpfs / ntfs / exfat)。< / p>
我已经努力解决了同样的问题,并通过在三星Galaxy Note 3上形成了一个完全空白的未分区的200GB MicroSD卡,在三星Galaxy Note 3上使用Android 4.4.2以及Windows,以及Aparted Android。< / p>
如果您尝试从与exfat格式化的卡中恢复数据,但其分区错误地标识为分区表中的"FAT32(LBA)" 或"C" 或"0C" ,我相信您将需要强制恢复应用程序(例如TestDisk)将其标识为HPFS / NTFS / exfat或"07" 。
The reason is, at least with Samsung devices and cards larger than 32GB, Samsung or Android formats the card with the exFAT file system, but incorrectly identifies the partition type as "FAT32 (LBA)", or partition type "c" or "0c" in the card's partition table.
If you format the card with exFAT using Windows or the Android partitioning app Aparted, it will correctly declare the partition type as 7 or "07" for "exFAT" (HPFS/NTFS/exFAT) in the microSD partition table.
I have struggled with this same problem, and just confirmed the above information by formating a completely blank, unpartitioned 200GB microSD card on a Samsung Galaxy Note 3 with Android 4.4.2, and in Windows, and using Aparted on Android.
If you are trying to recover data from a card that was formatted with exFAT, but whose partition is incorrectly identified as "FAT32 (LBA)" or "c" or "0c" in the partition table, I believe you will need to force the recovery app (e.g. Testdisk) to identify it as HPFS/NTFS/exFAT or "07".
我在SGS 3中格式化了1GB Micro SD卡(Android 4.3),然后在PC上的Windows 8.1中检查它。 "属性" 对话框表示胖。 (PC也可以读取内容而没有任何问题)
我也将它格式化为PC上的exfat并将其放入手机上。它可以读取和写入它。另一方面,报告了NTFS卡为不受支持的。

根据本论坛帖子: [q]在s3上用于sd卡的文件系统是什么? :
任何32gb和下面都将是fat32。 64GB将被EXTFAT。
对于您的卡,最好的选择是尝试将其安装在Linux中(支持最多的文件系统,注意:对于Exfat,可能需要安装其他包)。如果它有效,请检查使用的文件系统,如将 CAT / PROC / MOUNT 。
I formatted a 1GB micro SD card in my SGS 3 (Android 4.3) then checked it in Windows 8.1 on a PC. The Properties dialog says it is FAT. (also the PC can read the content without any problems)
I also formatted it to exFAT on the PC and put it in the phone. It could read and write to it. On the other hand, a NTFS card was reported as unsupported.
More info:
According to this forum post: [Q] What filesystem is used for SD cards on the S3? :
Anything 32GB and under will be FAT32. 64GB will be extFAT.
For your card the best bet is to try mounting it in Linux (supports the most file systems, note: for exFAT an additional package might need to be installed). If it works, check the used filesystem, like with cat /proc/mounts.
