Last time ScanDisk and Defrag performed

 Keywords:  Last time ScanDisk and Defrag performed

Question:

Does anyone know of a way to check when the last time a user has performed a scandisk and defrag on his hard drive via a winbatch script? There is a LastCheck key in the registry that tracks this information but it appears to be in hexadecimal form. How would that correspond to a normal system date form? Any help would be greatly appreciated.

The keys that I am referring to are

HKLM\Software\Microsoft\Windows\CurrentVersion\Explorer\LastCheck and
HKLM\Software\Microsoft\Windows\CurrentVersion\Explorer\LastOptimize.

I believe that the info there refers to the information that you would see when you looked at the properties of a drive and viewed the tools tab in the Win95 environment for the last time a scandisk and defrag was performed. How the info in those keys corresponds to system dates is where I am hitting the roadblock. Any ideas? Thanks in advance.

Answer:

Maybe this will do it...

;LastOptimize
AddExtender("wilx34i.dll")
ret= RegqueryBin(@RegMachine,"SOFTWARE\Microsoft\Windows\CurrentVersion\explorer\LastOptimize[C]")
;D0 07 0A 00 05 00 06 00 0A 00 2B 00 27 00 2A 03
year = xHex(itemextract(2,ret," "))*256 + xHex(Itemextract(1,ret," "))
month = xHex(itemextract(3,ret," "))
days = xHex(itemextract(5,ret," "))
hour = xHex(itemextract(7,ret," "))
mins = xHex(itemextract(9,ret," "))
secs = xHex(itemextract(11,ret," "))
year = strfixleft(year,0,4)
month = strfixleft(month,0,2)
days = strfixleft(days,0,2)
hour = strfixleft(hour,0,2)
mins = strfixleft(mins,0,2)
secs = strfixleft(secs,0,2)
date = strcat(year,":",month ,":",days,":",hour ,":",mins ,":",secs)
message("LastOptimize date",date)

Heres an example that uses a UDF in lieu of the loading the WILX Extender

#DefineFunction Dec2Hex(Dec)
   IsZero=@TRUE
   str="0123456789ABCDEF"
   hex=""
   
   for x=7 to 0 by -1
       nibble= (dec >> (x*4)) & 15
       if nibble==0 && IsZero==@TRUE then continue
       IsZero=@FALSE
       hex=strcat(hex,Strsub(str,nibble+1,1))
   next
   return(hex)
#EndFunction

;LastOptimize
ret= RegqueryBin(@RegMachine,"SOFTWARE\Microsoft\Windows\CurrentVersion\explorer\LastOptimize[C]")
;D0 07 0A 00 05 00 06 00 0A 00 2B 00 27 00 2A 03
year = Dec2Hex(itemextract(2,ret," "))*256 + Dec2Hex(Itemextract(1,ret," "))
month = Dec2Hex(itemextract(3,ret," "))
days = Dec2Hex(itemextract(5,ret," "))
hour = Dec2Hex(itemextract(7,ret," "))
mins = Dec2Hex(itemextract(9,ret," "))
secs = Dec2Hex(itemextract(11,ret," "))
year = strfixleft(year,0,4)
month = strfixleft(month,0,2)
days = strfixleft(days,0,2)
hour = strfixleft(hour,0,2)
mins = strfixleft(mins,0,2)
secs = strfixleft(secs,0,2)
date = strcat(year,":",month ,":",days,":",hour ,":",mins ,":",secs)
