I may be able to help. I have had mixed success reading QIC tapes.
I have encountered two problems reading them.
1. Band failure. There is a band inside the cartridge that keeps the
tape taut when drive advances and rewinds the tape. These bands like to
fail. I have found replacements that
Hi Chen,
I just tried the tape drive and sadly it too has the capacitor leakage
problem like the CDROM drive.
So sorry but I cannot help reading your tapes.

Dear Tom,
Does your Sun workstation is functional and read QIC -150 cartridge?
I have some old 3M 6150 cartridges that was created by Sun Sparc workstation in
2000.
One those cartridges, I have some my personal files I like to get them.
If you can you read those cartridges, I can pay some money

Hi Liam,
You are probably quite correct.
In another forum someone came up with the same explanation for my "rat
problem".
Here is what he wrote:
"Were there any electrolytic capacitors in the region of the corrosion?
When an electrolytic capacitor leaks (even slightly) the electrolyte often

A friend had Western Dynex 10mb drives years ago which were hard to come
by. Equivalent to the RL02's.
He had a test system which could run Microdata Reality as a test station

I've heard of "factory rust" and "factory oil leaks,"
I removed the PCB off the CDROM drive and on closer inspection noticed a
region of substantial corrosion of solder joints on the component side.
About 70% of the PCB had solder joints that were nice and shiny like brand
new. The remaining section near the front of the drive was quite badly
I have now installed an old Adaptec AHA-2940 Ultra SCSI card with
micro-SCSI interface in a Windows XP PC. Windows successfully installed the
device driver and sees the Sony drive. If I attempt to read from the drive
I get a generic I/O error.
So it appears that the drives SCSI interface,
