SATA disk is Not Detecting While Linux bootup

Did you experience below kind of error anytime with SATA disk,

PCI: enabling device 0000:00:01.0 (0140 -> 0143)
ata1: SATA max UDMA/100 cmd 0xC2852080 ctl 0xC285208A bmdma 0xC2852000 irq 22
ata2: SATA max UDMA/100 cmd 0xC28520C0 ctl 0xC28520CA bmdma 0xC2852008 irq 22
ata1 is slow to respond, please be patient

after waiting you get
ata1: no device found (phy stat 00000000)
scsi0 : sata_sil

and at last
ata2 failed to respond (30 secs)

And you know how simple answer is for this.
Yes only thing is knowing is the key.

The answer lies in power source connector; SATA disks are very sensitive to power source, so if you see such errors coming while bootup and your SATA disk is not getting detected then press the power connector, And your are saved. This is my experience after struggling for an hour with changing SATA disk and changing SMPS, changing target board, but nothing worked; finally press hold on power connector to SATA disk and done. bbuuuurrr..

Linux SMB write performance With Simple Tips

SMB write performance can be increased by Tuning the buffer cache. The secret to good performance is to keep as much of the data in memory for as long as is possible. Writing to the disk is the slowest part of any filesystem. If you know that the filesystem will be heavily used, then you can tune this process for Linux Samba. writing out dirty blocks to the disk until the filesystem buffer cache is 80 percent full (80). default is 40%, source = http://tldp.org/LDP/solrhe/Securing-Optimizing-Linux-RH-Edition-v1.3/chap29sec287.html by writing echo 80 > /proc/sys/vm/dirty_ratio I am getting around 2MB increase while write operation, tested in Xp. I have tried with this single option, as the ref source is for linux 2.2 and we are using 2.6 kernel. we can try out Linux General Optimization suggested at http://tldp.org/LDP/solrhe/Securing-Optimizing-Linux-RH-Edition-v1.3/gen-optim.html Tried with smb.conf, I am getting around 1MB gain while read and write. socket options = TCP_NODELAY I...
