I'm another who can't get scandisk to work tho defrag works just fine
if I'm careful.

I've tried safe mode, no joy

I tried running it in DOS and got the error message
"
There is not enough free conventional memory to perform a surface
scan.

You may need to remark (REM) some device drivers from your CONFIG.SYS
file. Or, in your CONFIG.SYS file you made need to load the EMM386.EXE
driver to load your other device drivers into Upper Memory Blocks
using DEVICEHIGH= statements"

Thing is I've looked at config.sys and there doesn't seem to be
anything else I can do there:

It reads:

DEVICE=C:\WINDOWS\HIMEM.SYS
DEVICE=C:\WINDOWS\EMM386.EXE
REM [Header]

REM [CD-ROM Drive]
REM DEVICE=C:\CDROM\HIT-DVD.SYS /D:MSCD001
REM DEVICE=C:\CDROM\ATAPI_CD.SYS /D:MSCD001 /PIO

REM [Miscellaneous]

REM [Display]

DEVICEHIGH=c:\windows\setver.exe
DEVICEHIGH=c:\windows\COMMAND\display.sys con=(ega,,1)
Country=044,850,c:\windows\COMMAND\country.sys
[COMMON]
DEVICEHIGH=C:\DELL\RTC.CLK +R
REM DEVICEHIGH=C:\WINDOWS\COMMAND\DRVSPACE.SYS /MOVE

Anybody got any other ideas?

Regards and TIA
