Sparc Linux Hard Drive problems on Sparcstation 20

[spfanallen]

Hey everyone, I have a major problem with linux and a sun box. I have a SS20, and I tried to install Mandrake 7.2 on a 4.5Gb drive. After installing, the drive is not accessable, I cannot format it through the sun Format program, and no Linux distros can do anything with it. It keeps saying that my Partition table is invalid. I tried to repartition it through a solaris boot CD, and I keep getting write errors on track 0. This has happened to two of my best drives! Both worked fine with Solaris. Has anyone else had this problem??> Please help! Thanks!
