# hdparm -Tt /dev/hdc
/dev/hdc:
 Timing buffer-cache reads:   -3008 MB in  0.00 seconds =  -inf kB/sec
 Timing buffered disk reads:  -1504 MB in  0.00 seconds =  -inf kB/sec
Hmm.. suspicious results: probably not enough free memory for a proper
test. 

# hdparm -Tt /dev/hdd
/dev/hdd:
 Timing buffer-cache reads:   128 MB in  2.13 seconds = 59.98 MB/sec
 Timing buffered disk reads:  64 MB in  1.77 seconds = 36.24 MB/sec
Hmm.. suspicious results: probably not enough free memory for a proper
test.

Hvad pokker sker der her? 

Jeg har lige indsat nogle nye ATA133 skærmede kabler, for at sikre at
diskene kunne køre så hurtigt som muligt uden CRC fejl.

diskene er:
hdc: ST380021A, ATA DISK drive (Seagate Barracuda IV - 80gb)
hdd: Maxtor 6Y160L0, ATA DISK drive (Maxtor 160gb)

Årsagen til at jeg skiftede var dette output fra smartctl -a /hdc | grep
CRC

# smartctl -a /dev/hdc | grep CRC
199 UDMA_CRC_Error_Count    0x003e   200   200   000    Old_age      -  
   0 

# smartctl -a /dev/hdd | grep CRC
199 UDMA_CRC_Error_Count    0x0008   199   199   000    Old_age      -  
   0

Som den underligt nok stadig skriver - skal man nulstille disse tællere?
maskinen har selvsagt været genstartet, da jeg indsatte det nye ATA133
kabel.
