You know your in for a rough ride when the only advice you can find for a BSDO is to back up all data and format your drive. B.S.!
Working on a HP pc with windows Vista home, the customer was receiving a BSOD
0x0000c1f5
Hmm maybe an easy fix.. Yeah right.
What MSKB had to say..
SYMPTOMS
When you start a Windows Vista-based computer, you receive the following Stop error message on a blue screen:
0xC1F5
CAUSE
This issue occurs because the Common Log File System (Clfs.sys) driver does not fix the $TxfLog file when the file is corrupted. In addition to the Stop error message, Windows Vista may not start during startup until the offending disk is removed from the computer.
