Restoring Geometry on my 1G Flashdrive
I have a 1G flashdrive made by Easydisk link below:
http://www.amazon.co.uk/EasyDisk-fla.../dp/B00096JDIK
I should have known better than to trust windows with my data but it corrupted my disk. I have data back though windows had resized the drive
to 500M.
I have reset the geometry with linux fdisk but unsure of original CHS geometry.
This is output from dmesg:
fdisk /dev/sdc

Drive is working if I manually mount it although the kernel generates a few errors:

Not sure which is correct , maybe someone has same drive and can post output from fdisk or hdparm, or any suggestions?
Thanks in advance. |
