This is a real story about how to Solve SD C4 Error
Hello this is Paul, last week, I got Star diagnostic software for my old SDconnect c4 at obd2shop.co.uk, comes with the Dell D630 HDD. Then I installed it in my Dell D620. Installed all drivers and activated it but there was no “LAN CONNECTIONS” information, only the error message: “A disk read error occurred. Press Ctrl+ Alt+ Del to restart-”
After our engineers checking , here it is :
Here is the tips mbstarshop technicians offered
1. Poor connection between computer and hard disk.
2. The hard disk is broken, like the picture below.
Here is the way to solve we suggest Mr. Paul
Unplug the hard disk and reinstall it.
If it still fails to use, buy a new hard disk for sd c4.
