[Enable48BitLBA | Break the 137Gb barrier!]

From your procedure above it seems like it is indeed working.

Looks like defrag from WinME does work with partitions bigger than 128Gb...

One more confirmation: I'd like a screenshot of the Properties page of the 300Gb drive being filled past 137Gb, ajacent to the information dialog from a successful scandisk'ing.

yes i did the file copy in dos

i used the win98 cd to boot to a c: prompt

Wrong procedure. DOS 7.1 uses Int13x which supports 48-bit LBA. It has nothing to do with ESDI_506.PDR.

ok in extreme detail here is what i did

1. download 4102225F.ZIP and unzip

2. copy esdi_506.pdr to root dir of c:

3. reboot using win98 cd to plain old dos

4. dos commands as follows

cd windows

cd system

cd iosubsys

rename esdi_506.pdr esdi_506.bak

5. copy c:\esdi_506.pdr

6. shutdown

7. install 300gb drive as drive d:

8. boot to dos and fdisk drive

9. boot into windows and format drive d:

10 copy lots and lots of files to d:

11 run scandisk and it does not work

12 run defrag and it does not work

13 downloaded this

Did you copy the files from DOS or Windows? All the copy operations must be done through the driver (disk access must not be in 16-bit "MS-DOS Compatibility Mode"). I have posted a recommended procedure a few posts previous.
