I have some problem with the micro SD card I usually use on my phone. I recently updated my phone to Android 6 and it is now asking me to format the SC card.
However it always fails.
I tried to format it in the computer (Windows 10), using a cheap USB stick adaptor. Quick format fails and complete format fails at the end after more than two hours running.
I tried EaseUS Partition Manager to format the card, but had a similar result:
There are some error occurred while writing partition chains on disk.
A Google search pointed me to the testdisk utility, which gave me the following message:
Current partition structure: check_FAT: Unusual media descriptor (0xf0!=0xf8) Warning: number of heads/cylinder mismatches 4 (FAT) != 255 (HD) Warning: number of sectors per track mismatches 16 (FAT) != 63 (HD) P FAT32 0 0 1 3852 194 54 61894656 [NO NAME]
On Linux (I'm not an advanced user), the system detects the card but cannot mount it.
dmesg gives me the following information:
[ 146.356105] usb 1-5.3: new high-speed USB device number 3 using ehci-pci [ 146.443845] usb 1-5.3: New USB device found, idVendor=058f, idProduct=6335 [ 146.443850] usb 1-5.3: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 146.443853] usb 1-5.3: Product: Mass Storage Device [ 146.443856] usb 1-5.3: Manufacturer: Generic [ 146.443858] usb 1-5.3: SerialNumber: 058F011111B1 [ 146.457414] usb-storage 1-5.3:1.0: USB Mass Storage device detected [ 146.457759] scsi4 : usb-storage 1-5.3:1.0 [ 146.457893] usbcore: registered new interface driver usb-storage [ 146.459336] usbcore: registered new interface driver uas [ 147.460498] scsi 4:0:0:0: Direct-Access SD/MMC Card Reader 1.00 PQ: 0 ANSI: 0 [ 147.460920] sd 4:0:0:0: Attached scsi generic sg5 type 0 [ 147.876455] sd 4:0:0:0: [sde] 61896704 512-byte logical blocks: (31.6 GB/29.5 GiB) [ 147.878693] sd 4:0:0:0: [sde] Write Protect is off [ 147.878698] sd 4:0:0:0: [sde] Mode Sense: 03 00 00 00 [ 147.880945] sd 4:0:0:0: [sde] No Caching mode page found [ 147.880950] sd 4:0:0:0: [sde] Assuming drive cache: write through [ 147.893705] sde: sde1 [ 147.905230] sd 4:0:0:0: [sde] Attached SCSI removable disk
The card can be used on Windows, I can read, write and copy files on the PC but not in the phone, and I cannot format it in any way.
Any suggestions about what I could try?
