You probably didn't read my instructions correctly and wrote zeros to the partition table of your disk. Probably over the first 1GB of data as well.
Depending on the original filesystem the data on the drive may be toast. A program like testdisk might be able to recover the data that was on there.
If there was no data on there just repartition using the Ubuntu disk utility.

Hi, i find this thread from Google and i want to share something here.
You can test SD Card / MicroSD Card with H2testtw 1.4
I Use it with wine 1.3.34 to test my MicroSD , i have Visipro 16GB Class 10
Info from dmesg
and here the h2testw result:Code:device eth1 entered promiscuous mode usb 1-3: USB disconnect, address 21 usb 1-3: new high speed USB device using ehci_hcd and address 22 usb 1-3: New USB device found, idVendor=048d, idProduct=1336 usb 1-3: New USB device strings: Mfr=1, Product=2, SerialNumber=3 usb 1-3: Product: Mass Storage Device usb 1-3: Manufacturer: Generic usb 1-3: SerialNumber: 00000000000006 scsi29 : usb-storage 1-3:1.0 scsi 29:0:0:0: Direct-Access Generic Storage Device 0.00 PQ: 0 ANSI: 2 sd 29:0:0:0: Attached scsi generic sg4 type 0 sd 29:0:0:0: [sde] 31291392 512-byte logical blocks: (16.0 GB/14.9 GiB) sd 29:0:0:0: [sde] Write Protect is off sd 29:0:0:0: [sde] Mode Sense: 03 00 00 00 sd 29:0:0:0: [sde] Assuming drive cache: write through sd 29:0:0:0: [sde] Assuming drive cache: write through
I Hope it could help you guys.
The read write performance test can be done with the help of couple of tools available out there..Taking an average out of all of them will be a better way to determine the actual speed.
Some tools are as below:
etc...Some of the tools are explained here.
