#31 hdparm fails on Intel X25-V G2 40GB SSD

[Anonymous]

Hello,

I have the Intel X25-V G2 40GB SSD and get this output:
korn@ubuntu:~/hdparm$ sudo wiper --commit /dev/sda1

wiper: Linux SATA SSD TRIM utility, version 2.5, by Mark Lord.
Preparing for online TRIM of free space on /dev/sda1 (ext4 mounted read-write at /).

I used this configuered script for Intel SSDs:

I also tried this script which also tried to fix the Intel related 500 ranges bug (but using perl):

It also fails with the IO-Error
