Hi.
I saw that WipEout 2097 was changed in the DB.
http://redump.org/disc/1041/changes/

I have the old data track with the following hash:
Size:    86327808
CRC32:    ea86c3d4
MD5:    abc728b3e189583dab445c308aa0bea8
SHA1:    785fbd4f6b9cd0c15893cc82b39a757f34f1f1b7


I tried redumping my disc and it has a read error at sector 36703 (last sector).
This seems to be normal: http://forum.redump.org/topic/246/added … sles00327/
psxt001z --fix adds a correct header and sets user data to all zero.
This is how the old hash comes together.

What do I have to do to convert it to the new hash?

It has to do with the earlier NoEDC Sony PSX discs, which had audio tracks included.

There is no extra topic explaining that, but it was explained many times in different topics,
please look around yourself, or maybe somebody can point you directly to an explanation posting.

Edit:

the dumping guide has been changed some months ago,
now you don't have to use the psxt001z --fix option, which was cleaning the last sector.

Most drives extract the last sector without problems, only some drive brands are affected:
- plextors (which can be used in scrambled mode, or after disabling the ECC correction mode)
- pioneer
- and some other manufacturer

PX-760A (+30), PX-W4824TA (+98), GSA-H42L (+667), GDR-8164B (+102), SH-D162D (+6), SOHD-167T (+12)

You are right, my LiteOn DH4O1S BDROM was able to read the sector. My Sony NEC Optiarc AD-7240S could not.
